Help setting up a new printer

Hello everyone!

So I bought a prusa i3 kit back in January and have just finished assembling it last week. I have the arduino program installed and the marlin firmware loaded on the card, and pronterface installed and working. I can connect to the printer and move around the xyz axes, but i have two problems. When i press the home all button, i believe my z axis motors make this horrible high pitched sound for like 60 seconds, then stop, any commands entered during this state are delayed until it is finished making this sound, then they are carried out, however the z axis does not move. As for my second problem, i have no idea how where my home should be, or how to set this up. my endstops are a little backwards i know, but there is a way by editing the firmware to fix this or so i have read. The endstops for this particular kit (diytechshop.com) are of rather poor quality as they need to be ziptied to the frame, which i intend to replace after the printer is working and i can print new holders and buy new endstops. Anyway here is a picture of the printer which shows the locations of the endstops.



The y endstop is at the very front of the printer, the x endstop is on the right side of the x-axis, and the z endstop is on the bottom left side of the z-axis.


Any help would be appreciated!

Thanks,

-Jake

Hey Jake. When you wired your steppers, did you take a multimeter and verify what coil you were on? The steppers that I received from DIYTechShop were wired completely backwards from a standard wiring used by a bigger name manufacturer. Judging by the picture of the i3x, your steppers look as meek as mine. I would verify that they are wired correctly.

The below is intended if you have not checked the wiring. If you have you can ignore it:

If you have a 6 wire stepper there will be two pairs of wires that will yield approximately 12 ohms when measured across them. These pairs are the coil pairs that you will wire. For 4 wire steppers, there should be around 4-6 ohms iirc.


As for the endstops... I suggest printing these out as the first, after calibration, print. [www.thingiverse.com]

Also, you have your X and Y endstops on the MAX side, and your Z endstop on the MIN side. I suggest either moving the Z-axis to the same side as your X axis, or moving the X and Y to the opposite sides.


The way that I have my endstops setup are:

The Y Axis is behind the Z-Plate. In your picture it would be by your monitor. This is Y-Min in my firmware and how it is plugged into the RAMPS board

The X-axis is on the left side by the stepper, again this is X-min in my firmware and RAMPS

The Z-Axis is directly below the X-axis stepper and endstop. Once again it is setup as Z-min in firmware and RAMPS. One thing that might make your life easier is to print this by user N9JCV: [www.thingiverse.com] . It will allow you to make small adjustments to between your nozzle and bed once you have the bed leveled.

The last item is that you will need to turn off the MAX_ENDSTOPS in the firmware. Look for #define DISABLE_MAX_ENDSTOPS specifically, and uncomment it.

If you change your Z axis then all you have to do in the Firmware is uncomment #define DISABLE_MIN_ENDSTOPS, and ensure that your endstops are plugged into the + endstop slots on your RAMPS.

Thank you so much for the reply! I did check to make sure the stepper motors were using the correct coils and I believe that I have them set up correctly with the 12 ohm resistance between 2 of the three wires, does it matter which pair though is plugged on the left and right two wires? For me there were the 6 wires: brn blk org red wht ylw, in that order, the brn and org had 12 ohm as well as the red and ylw, so I connected them to the ramps in that order, the brn wire on the left side, and the ylw wire on the right side. Again I can move the motors perfectly on pronterface, I just needed to turn the the mm/min speed down to 500 for the x/y axes and 8 for the z-axis or they wouldn't move and just make that high pitched noise, which that took me like a week or two to figure out.

As far as the endstops, the y axis isn't long enough passed the z plate to fit the endstop. It would cut off about two inches of build space, so I put the endstop on the max side. I will just put the z endstop on the max side as well, however the kit came with just the two wire pin, and the S and + pins are spaced out for 3 pins, does this mean I need to go buy new wires that have the 3 pin?

here are some pics of what I was talking about respectively.

there is not enough room for the y endstop on that min side:



the wires out of the motor:



the wires on the ramps from the motor, the purple goes to the brown, blue to the orange, the black to the red, and the red to the yellow:



lastly, on the endstop pins for the ramps, my wire connectors just have the two pins hooked up to the (S) and (-):

For the endstops, you will want to make your Z-endstop a MAX endstop then so that you can disable the MIN side then. Also move them up one spot. Look at this diagram It shows X- , Y-, and Z-. It looks like that is where you are currently plugged into. Move them all, in the image linked, to the right by one spot and this becomes X+ , Y+ , Z+.

As long as you are keeping your wires all the same, and your steppers are the same, there shouldn't be any reason they will not work then. Your wiring of brown/orange on the first two pins, then red/yellow on the last two is perfectly valid. You have stated that you can move them in Pronterface? Perhaps fixing the endstops and being able to home will correct the movement issue.... You could be at the end of the travel on the Z-Axis.

okay, i looked at the diagram and have moved the pins down to the XYZ+ pins, and moved the z endstop to the top, now i will try to disable the min endstops! thanks for your help, I'll keep you posted!

okay I am lost. I found where to edit this in the firmware the configuration.h file, and i found where it says #define DISABLE_MAX_ENDSTOPS

but that is it. I know not exactly what i am doing here, do i need to replace this with the min endstops bit? the whole sections says:

If i change the disable max endstops to min endstops, do i have to change anything else such as the inver stepper pins or anything like that?

Are you using the Marlin that came with the kit, or did you download a fresh copy from GIThub?

I suggest getting the fresh code instead of messing with DIYTechShop's modified version. For example, in the fresh copy I have:

// The pullups are needed if you directly connect a mechanical endswitch between the signal and ground pins.
const bool X_MIN_ENDSTOP_INVERTING = false; // set to true to invert the logic of the endstop.
const bool Y_MIN_ENDSTOP_INVERTING = false; // set to true to invert the logic of the endstop.
const bool Z_MIN_ENDSTOP_INVERTING = false; // set to true to invert the logic of the endstop.
//const bool X_MAX_ENDSTOP_INVERTING = true; // set to true to invert the logic of the endstop.
//const bool Y_MAX_ENDSTOP_INVERTING = true; // set to true to invert the logic of the endstop.
//const bool Z_MAX_ENDSTOP_INVERTING = true; // set to true to invert the logic of the endstop.
#define DISABLE_MAX_ENDSTOPS
//#define DISABLE_MIN_ENDSTOPS

Where as your C&P does not have the MIN line in it. You could try adding it and commenting out the DISABLE_MAX_ENDSTOPS, but I don't know for sure if DIYTechShop has left that function in there or if they stripped it out.

As for the inverting bit... That is only needed to change from a Normally Open endstop to a Normally Closed endstop. That will depend upon how you wired it. If you have them wired as NC, the INVERTING will be false as in my pasted example. If you have them wired NO then it will switch to true. Does that help?

Yes that helps, I am pretty sure they are to nc, as in most guides. I will try to download a new copy of the firmware from that site when I get home from work tonight and then see if that fixes it!

Have you set the z axis steps in configuration.h or in eeprom? [calculator.josefprusa.cz]

I had the same problem with my motors and this fixed it.

Note, these are for my printer - you will have to change them ( refer to that calculator )

#define DEFAULT_AXIS_STEPS_PER_UNIT {100,100,2560,84.30}
#define DEFAULT_MAX_ACCELERATION {120,120,150,80} // X, Y, Z, E maximum start speed for accelerated moves. E default values are good for skeinforge 40+, for older versions raise them a lot.
#define DEFAULT_ACCELERATION 150 // X, Y, Z and E max acceleration in mm/s^2 for printing moves

For the z steps, you want to change the Z max acceleration. You likely also have to do this in your slicer/host application as well. In repetier host, go to printer configuration and then behavior. Change z axis travel feedrate down. I started at 50 then bumped by 25 until I hit that high pitched noise. Then back it down by 25 and go with that. In repetier I currently use 100 and that is working pretty well.

No I have not bilsch, I'll have to give that a try as well when I am working on it tonight! Thanks. Bunch, I'll let you know how it goes!

So lukan, I put in the new marlin code, and edited some stuff so that it is similar to the items that diy put in for their setting, i guess this is called editing the firmware. I no longer have the noises when hitting the home button, and my endstops are now actually registering, however i think my printer thinks that everything is at the end, when its at the max? Im not sure, this is hard to describe. For example, my X-axis is at the Max side where my endstop is located. When i try to move it towards the min side, pronterface says that it is hitting an endstop and lets it move .02mm at a time. Also now, the z-axis has been inverted completely! When i try to move it down on pronterface, it moves up and vice versa.

I feel like i just dug myself in to a bigger whole then i was earlier!

Does your Y-axis endstop really sit on that backside as this kit suggests? How does your bed go all the way through if the kit suggests that there should be a 7cm gap between the Z-plate and the rear feet?

Anyway here is my code for the endstops which im sure are all messed up. Is there a guide for this section somewhere online maybe?

Jake, It is ok. If your steppers are moving the wrong way, Just invert them.

#define INVERT_X_DIR true    // for Mendel set to false, for Orca set to true
#define INVERT_Y_DIR false    // for Mendel set to true, for Orca set to false
#define INVERT_Z_DIR true     // for Mendel set to false, for Orca set to true

You said that the Z axis is going the wrong way correct? The change would look like:

#define INVERT_X_DIR true    // for Mendel set to false, for Orca set to true
#define INVERT_Y_DIR false    // for Mendel set to true, for Orca set to false
#define INVERT_Z_DIR false    // for Mendel set to false, for Orca set to true

As for the endstops:

// The pullups are needed if you directly connect a mechanical endswitch between the signal and ground pins.
const bool X_MIN_ENDSTOP_INVERTING = true; // set to true to invert the logic of the endstop.
const bool Y_MIN_ENDSTOP_INVERTING = true; // set to true to invert the logic of the endstop.
const bool Z_MIN_ENDSTOP_INVERTING = true; // set to true to invert the logic of the endstop.
const bool X_MAX_ENDSTOP_INVERTING = true; // set to true to invert the logic of the endstop.
const bool Y_MAX_ENDSTOP_INVERTING = true; // set to true to invert the logic of the endstop.
const bool Z_MAX_ENDSTOP_INVERTING = true; // set to true to invert the logic of the endstop.
//#define DISABLE_MAX_ENDSTOPS
#define DISABLE_MIN_ENDSTOPS

You have everything moved over to max correct? I would comment out the MIN endstops which would have this section looking like:

// The pullups are needed if you directly connect a mechanical endswitch between the signal and ground pins.
//const bool X_MIN_ENDSTOP_INVERTING = true; // set to true to invert the logic of the endstop.
//const bool Y_MIN_ENDSTOP_INVERTING = true; // set to true to invert the logic of the endstop.
//const bool Z_MIN_ENDSTOP_INVERTING = true; // set to true to invert the logic of the endstop.
const bool X_MAX_ENDSTOP_INVERTING = true; // set to true to invert the logic of the endstop.
const bool Y_MAX_ENDSTOP_INVERTING = true; // set to true to invert the logic of the endstop.
const bool Z_MAX_ENDSTOP_INVERTING = true; // set to true to invert the logic of the endstop.
//#define DISABLE_MAX_ENDSTOPS
#define DISABLE_MIN_ENDSTOPS

It is essentially how I have mine set up, and without commenting those out the system thinks that you have them wired up but there is nothing being registered. If you don't want to comment them out, change the MIN_ENDSTOP_INVERTING to false.


OH!!! I also noticed this section!!!

// ENDSTOP SETTINGS:
// Sets direction of endstops when homing; 1=MAX, -1=MIN
#define X_HOME_DIR -1
#define Y_HOME_DIR -1
#define Z_HOME_DIR -1

CHANGE THOSE ALL TO 1!!!!!!

Good news! It is working better after those adjustments! All of the axes are moving in their respective directions, as well as all of the endstops i believe are recognized. I think that the printer thinks that being at the max is also the home direction right now. Im kind of not sure what is going on at this point with it. The X-axis is still having that problem when i move it towards the min position (it is currently at the max where my endstop is located) pronterface is saying that it is hitting the endstop and only moves .02mm towards the min. Also the endstops arent working to stop it when it hits them. Could this be a problem with the endstops not being set as the end of its 200mm path?

Okay so here is what my config.h looks like now. I still have yet to set my axis steps per unit (I looked at that page bilsch to calculate it and it is all greek to me. i could probably count all the teeth on my pully, but im not sure how do to any of that!)

// True == Normally Open

Then change out your MAX_ENDSTOP_INVERTING to false. This should allow you to start moving fully.

That is pretty cool! The y and z axes are working perfectly (except for their positions being off)! It is pretty neat sending the 100mm command and having the endstop actually stop it! The x-axis is still acting a little funny though. It doesnt stop at the endstop when i move it all the way towards the max. but when i hit the endstop and try to move back towards the min side, while the endstop is triggered it only moves .02mm and says that the endstop is triggered. So this leads me to think maybe the machine thinks that the endstop is on the min side still?

And thank you so much for your help! it feels like I am so close to calibrating the bed then printing something!!!!

No worries at all Jake. Being one of the relatively new nubs to printing I understand the feeling.

#define INVERT_X_DIR true    // for Mendel set to false, for Orca set to true

When you try to move your X, does it go in the expected direction? I noticed that your definition for travel direction is different than the other two. I didn't think anything about it until now since you are still having issues with your travel on that axis. The only other things I can think of that could be causing this is that the endstop is either still plugged into X- on the RAMPS, or it is connected as NO. When you start up in Pronterface, send the command m119 and see what it returns. Then hold the X-endstop and send the m119 command again and make sure that it changes. It sounds like it is, but it is always nice to make sure when there is a problem. About the only other thing to check is that there is continuity through your cable. This can be checked simply by unplugging the endstop, then using a multimeter on the lowest ohm setting measure the resistance across the connector pins. On an NC endstop it should read 0 ohms, of very close to it.

Just a quick thought...have you jumpered the unused end stop header pins on the ramps board? The switches trigger when they are in the open state when wired for 'normallly closed' No jumpers in the headers tricks ramps into thinking the other end stop has been hit (even if you don't actually have the end stop there). So you can either jumper the headers, or reverse the end stop logic in the configuration file.

That is normally true Shane, except that if you setup #define DISABLE_MIN_ENDSTOPS then you do not need to worry about jumpers. This command turns those pins off completely.

okay so I was toying with it tonight lukan, i moved the x-axis away from the max, where it was triggering the x endstop. and it was moving left and right perfectly, but when it hit the max endstop it wouldnt stop! So i decided to move the x-axis towards the min (away from the endstop) and i triggered the endstop with my hand, and voila! it stopped. So then im thinking, okay.... the endstop thinks its at the min position instead of the max! but then i thought wait a sec... for some reason as you stated the x axis is inverted! well before i did any of these tests i tried setting that to true, and the axis was moving backwards. So i reinverted it and then ran these tests now. Im wondering if because it is inverted that the endstop is also inverted! this would explain me having it set as a max but is being registered as a min. Any thoughts?

Well, as I stated above... The inversion of the endstop will switch it from NC to NO and vice-versa.

Also, the inversion of either endstop or stepper will only affect the endstop or the stepper.

When the stepper was inverted, the only thing that would affect the endstop is the :

// Sets direction of endstops when homing; 1=MAX, -1=MIN
#define X_HOME_DIR 1

I guess the thing to remember here is that your movements are all going to be on the cartesian coordinates.

If your movements are moving correctly on that coordinate system, and your endstop is triggering on the MIN side still, go back and check where that is actually connected to on the board.

Well the endstop is working, it is on the NC tab, and it shows triggered when i send the m119 and i hold it down, and not triggered when i send it and its not triggered. This should show that there is connection, and i looked back at that diagram you sent earlier and they are in the pins under the -X endstop. so it should be wired correctly. If i put it in the xmin slot, and set the printer to register it as the min. would the printer function correctly? or does everything need to be min or max?

Or, would it work just as it is, if i just move the x endstop over to the min side that it thinks it should be at? would the printer function correctly?

Well, remember that we disabled your MIN endstops. You would have to go in and comment that back out, then there is a small amount of work to get the un-used endstops setup properly, and you will have to follow Shane's advice and use jumpers on the unused header pins. I will be unable to help much after that as I have not gone that route and wanted the firmware to be as simple as possible to setup so I made everything MIN and disabled the MAX side.

Now.. you say that the endstop is under the -X pins. I am assuming that you have your board 180 from my board. Just to make sure that I am thinking properly, you have it plugged in between the -X and -Y pins correct?

Another thing you can try now is to send an X-home command and see which way the bed is moving. Then trigger the endstop. If it stops the bed, put the endstop on the side that the bed was moving.

This is how my board is set up.



all of the endstops were in the (-) pins, now they are in the ones under them which are the (+). I would like to keep them from needing to be jumped and just use the firmware.

I just hit the X-home and it sent the printer towards the min and it hit the very end and kept going and grinding because it could not move, and it turned my power supply off, it stopped, i turned it back on and it kept going, then i thought to hit the endswitch. then i thought of something!

my printer is backwards!!!! i think this is it! you know how the x direction is set to false and the other two are true? well my printer is facing away from my monitor! but when im at the monitor and i hit go left, it goes left from where i am sitting! but if i actually go to the front of the printer and hit left, it would be going right! wow i feel so stupid!

so alls i need to do is put that backwards, and when i hit left it will actually go left instead of right (which appears left from the back side).

wow...

oh man

it is working! i feel so happy! endstops are all done and working now!!!!!!!!!

I hit x-home and it goes, to the max, hits the endstop, goes away from the endstop for 2 inches then goes back to the endstop and stops!

good deal. So does this mean i am ready to set my bed size and then calibrate it with the sheet of paper then i am ready to print?

alrighty, here is a video of it homing. I feel so proud! thank you for your help getting this far!

It will home, then go back a little bit, and then slowly go towards the endstop. in that last trip back to the endstop its very sluggish and slow and the motors sounds like they are struggling. im sure that is just changing the speed or power in the firmware. but i feel so relieved to have gotten this far, which i could not have done without your help lukan!

Awesome! Now you can start working on Triffid's Guide for Calibration!!! Do the WHOLE thing mind you... If you go all the way through that and finish the Fine Tuning steps as well, you will be putting out some real quality prints.

Here are some prints to help you out:

The main calibration cube:
Calibration Box

Triffid's guide has the 5mm cube pyramid in there which is useful after getting your rough tuning done with the above block.

Extra just to see where your printer stands with overhangs:
Overhang test

Then you should be off and ready to go.

thanks for the information! quick question though. i know the formula for the stepper motors steps per revolution, but i dont get how to find this out.

okay after looking online i think there are stickers on the motors that tell you about the turns, ill have to inspect the motors tomorrow. but i did see someone said in a post you need to put jumpers under each of your stepper chips? i saw my bag of jumpers today and no instructions anywhere said i need them. am i missing out on anything? everything apears to be working though?!
