alright, day two of troubleshooting and my hot end is getting...too hot. Is this a common problem or have I missed another glaring obvious step? If not, I have an old heat sink I can wrap around the stepper motor to cool it.
here's my on the fly fix for a test print that's at 90%
I was able to resolder my thermistor and with a little bit of kapton tape it's fixed (I order one replacement from FolgerTech and one set like the one that Sonnylowe mentioned, let's see which one get here first), I just put today the endstop brackets (the original ones) and I think I got all the wiring right, tomorrow I will get the firmware loaded on the arduino, adjust the voltage on the Drivers, and install Repetier on my laptop so I can do a quick hardware check (not printing, still waiting for the borosilicate glass)...
What host are you using?
Not to be a downer, and I'm aware that there is failsafe code in Marlin, but make sure you don't leave the area while you're printing until you get your replacements. No one wants to see your place go up in flames because of a failed thermistor
I'm only using the fixed one to get the software running and poke around to get familiar with it and testing that the extruder heating element is running... I'm so limited on free time that if i can print something it's going to be until next week and according to the traking numbers the two new thermistors are supposed to arrive Saturday so i will have the extruder fully functional to print the test cube next sunday (?)
I have a question, when connecting the endstops i notice that there are more headers label endstop on the board. I followed the instructions and connected my on the 3rd, fifth and last connector (positive on top signal on the bottom).... what is the function of the other ports?
There is a min and max endstop for each axis. If you load my updated firmware, you're going to want to move the x-endstop one set of pins over to max (this is the correct marlin behavior, folgertech has it wrong in the guide)
Ok... so there are two sets of connectors per axis and we can have a max and min endstop, it make sense, avoid damaging the machine when the values input are out of the physical limits of movement for the printer. I have my end stop for X on the right side and I'm ready to upload your firmware, did I need to change the endstop to the left side and move the connector to the 5fth position or it's ok if i keep it physically on the right side and only change the position of the Dupont connector from row 6 to 5?
by the way I have the 2004 LCD and want to install it now, I found on the RepRap wiki that I need to change the follow lines on Marlin to get it working:
"In "Configuration.h”
Change line 46 to #define MOTHERBOARD 33
Change line 306 to #define REPRAP_DISCOUNT_SMART_CONTROLLER (just remove the // at the beginning)
Change line 326 to #define NEWPANEL //enable this if you have a click-encoder panel (just remove the // at the beginning)
Switch over to "Pins.h" and change line 318 to #define RAMPS_V_1_3 (just remove the // at the beginning)
Upload the firmware, power off the Arduino, connect the panel, reapply power, and everything should work."
This changes are mention for V1 of Marlin, did the same changes need to be made on your updated firmware?
You keep the physical location of the endstop on the right side, and move the dupont connector. You'll also need to change X-endstop to MAX in your host.
As for the LCD stuff, I already have the 2004 LCD enabled in the build, so it should work without having to change anything.

I was enabling the EEPROM settings on the configuration.h file and while saving I end up getting a general error about file extension changes from .pde to .ino... I'm not sure if the change will affect the functionality of the marlin on the printer of it should work as intended when the code is compiled and sended to the arduino.
my experience on arduino microcontrollers tell me that there should not be any problem.

[attachment 64344 image.jpg][attachment 64345 image.jpg]Though you guys might like to see this. I am learning the ins and outs of support material. They weren't perfect for the helmet but they don't have to be. Some were a little thin and it took me awhile to figure out how to properly attach them at the base. Sorry I don't have shots of the helmet before I took the supports out. Pulling them off was a piece of cake. I may do this one again at half the letter height. This one was 0.2 mm. I continue to be amazed by this kit!

I got to test out my cooling fan shroud for the X axis motor over the weekend. [www.thingiverse.com]
Before I had it mounted, the motor would typically run 135 F as measured with a surface pyrometer. Now with the fan running, after 1 1/2 hours of intense movement , it's staying at 90 F! That gives me some piece of mind.
Yeah, if your x-axis motor is too hot, you have your driver's voltage set too high.
Also, anyone interested in seeing what it takes to print Ninjaflex with a bowden setup?
More details to come soon...
I would love to know if that would work...I have a couple Nijaflex project in mind and the Bowden Extruder thing is holding me back...
It does work! I did a lot of research trying to find an extruder that can handle the filament, and this one was the best I could find. Only problem is it requires a stiff 7mmx30mm spring, but all I could find was a soft spring, and it was causing the gear to slip on ABS. I had a 7mmx20mm spring laying around from my old Folgertech extruder, so I remixed the part to the use it. I'm going to reprint this piece mirrored and rotate the motor direction, you'll see why when I post a pic of the installed extruder later.
After printing a bracelet for calibration, I printed this octopus and took a poorly lit photo last night...
Happy enough with the results, I didn't expect to have it come out as clean as my ABS prints.
A few things were learned printing this stuff...
1. Because the extruder compresses the filament as it pushes it out, I lose about 10% of extruded length (when extruding 50mm of filament, I get ~45mm), so you'll have to up your extrusion multiplier in your host.
2. This stuff really doesn't want to start flowing until all of the previous is completely out of the extruder. Its melted viscosity made it difficult to push out the last bits of ABS, but it was eventually able to do it.
3. Since it's compressing inside the bowden tube, you need a decent amount of pressure behind it to get a good stream going when it's time to print. To fix this I print 7 skirt lines.

The X axis assembly is the one that was done by therippa. The lower support in the picture has a bearing in it for 5mm. I turned the end of the 8mm screw down to 5mm.

Which X axis assembly? I tried looking and haven't found it.. I saw it before but didn't keep track. Is it the same one he uses with his bowden setup?
I'm starting to look into different extruder.. while I am at it.. should change out the carriage.

So I am attempting to print the t-rex skull which is one of the more popular things to download from Thingiverse. The model looks amazing but I am running into a few snags. It's not a simple geometry like my prior prints and there are a lot of complex curves and angles. I get about 1/4" up from my build plate and the outer edges of some of the print areas start to curve up above the build plane as the layers cool. I'm assuming this is a cooling issue so I am working on getting my cooling fans now, but I wanted to check and see if anyone can verify that is in fact the problem. Thanks! I'll send some pictures later if it will help.

What material are you printing in? If it's PLA, the fan will help.

My printer it's working!
Today I got on the mail the two thermistors so I decide to install the screw in and keep the one from FolgerTech on the bag as backup.
After uploading the firmware and setting Repetier I was able to adjust the end stops for the X and Y axis and get the Z almost ready, plus I was able to test heating bed and heating element on the extruder... the only steeper that I wasn't able to test was the one on the extruder, everytime that I try to make it go Repetier keep telling me that extruder it's too cold to do it , I guess I need to let the extruder get hotter than 70 degrees!
The whole build take me forever but it's complete! I only notice two details:
There is a faint buzzing noise coming from the steepers on the Z axis, the noise it's only noticeable while idle and the motors move fine on both directions and there is not problem moving the whole extruder assembly, while I know that the steeper motors and servos tend to buzz because of the nature of their design, I think that maybe I should increase or decrease a little the voltage on the drivers and see it that helps to reduce the noise (I will prefer to avoid the "decrease voltage" to keep the torque in the steeper as close as possible to the max).
I have a bunch of screws and nuts left!

Ok, so I gave up calibrating my 2020, and loaded the new marlin firmward from the link in your signature.
I re-calibrated the extruder. The original values were 90, my calculations showed it should be 102... so I set it in the configuration.h file and reloaded it...
Now, I can manually extrude as much PLA as I want, but when I go to print anything, the PLA does not feed. If I stop the print, I can again manually feed as much as I want...
Any ideas?

Hi, my printer will not connect any more!
It has been working ok for about two weeks, but suddenly I get "Access to the port 'Com3' is denied". I have tried another cable, another USB port, and even another computer, but get the same messge.
The device manager reports that COM3 is connected to Ardunio Mega 2560.
AND, I tried to load a G-code file from an SD card, and the card reader does not even list the file. I suspect that the Ardunio has left this world.
Any ideas?

All right, I'm officially an idiot. I can't find the carriage .
Thought I found a close one but didn't fit animoose's parts that are reworked for leadscrews.
Got a link handy?

I have a couple of questions guys:
One, did the LCD display should make a beep or something? I know it works, I got temperature readings, the emergency stop works and some other details but not beep.
Second, any of you has upgraded its FT Prusa adding a second extruder?
