I'm on the fence with this one. Clearly you are one of the more knowledgeable gurus here so I respect your opinion. The Z axis is the least used axis as far as cycles go. Yes, movement must be accurate to have accurate layer thicknesses. However, the lowly threaded rod, once calibrated, should yield accurate movement. The X carriage and extruder assembly all hang on the Z threaded rods, so there's no backlash or looseness there since the nuts are always being pushed down against the threads. What are the real advantages of using the lead screws other than it looks more professional?

You are only thinking about one direction. You get backlash when you axis (Z for this instance) changes direction. In the beginning the nut and threaded rods will probably work fine as they are still tight. But over time the rod and nut will start to ware and this is when the backlash issue will happen. Thats why people made a double nut with a spring for the z axis like this one on thingiverse, z-anti backlash. Plus this is a kit printer. By improving it we get a better machine and more knowledge. Plus its just plain fun to tinker. Speaking of tinkering, how is TINKERCAD working for you?

I understand that when you change direction, the backlash comes into play BUT the Z axis never changes direction during a print. It's always moving up a step at a time. At least with the things I've printed.

Oh, yea, TINKERCAD is awesome for an easy to use program. I'm using it every day to modify things, combine things, invent new things, change wording on trophies for the grand kids, and even today I printed out a power window knob for the son's Jeep! I only wish it had the ability to easily chamfer or radius edges. Even rounding the corners of a square is a chore. There's no template for that. To that end I'm also learning AutoCad's free 123Design. I've used AutoCad from day one but never got into 3 D.

I fully understand the urge to tinker and improve. I'm a sucker for anything technological. Always have been for 72 years. smiling smiley I can program PLC'S in ladder logic and code, can program robots, design products, fly RC airplanes (60 years doing that), enjoy woodworking, am a part time potter and enjoy working on cars. Other than that, I just sit around and do nothing!!!!! hahaha I'm sure I'll have those lead screws on here whether I need them or not just because they are cool and it gives me an excuse to print some more 'stuff'. My printer has been going since 7 am printing 'stuff' for Halloween plus an X motor cooling shroud I designed with TINKERCAD. That's the only motor that gets hot and it has the lowest voltage by far. I read the specs on our stepsticks and it appears that they can only put out a max of 1.5 amps so anything goes. That's assuming FT hasn't changed them.

Was it you that wanted pictures of the latest version of the FT extruder drive? If so, I'll get some tonight.

I got my 8mm threaded rods from bangood and they were pretty good looking, i noticed some lateral movement and backlash which i did not like. I put the long small end of the nuts into the 3 jaw chuck on the lathe and kept crimping them until all lateral movement and backlash was gone. I use 20W50 synthetic oil (harley oil) on them and so far it is still solid. I have used 1 1/2 rolls of abs through it since i installed them and all is good. Now I am not letting the weight of the z carrage be held by the motors and adding load to the motor bearings and the spring action of the couplings I turned the end of the rod down to 5mm and used a bearing in a remade z rod support.

I understand that when you change direction, the backlash comes into play BUT the Z axis never changes direction during a print. It's always moving up a step at a time. At least with the things I've printed.

If you have it set to lift as it crosses over you tell it how much to lift and then it goes bach to its correct hight when it starts back. I was using petg and getting alot of strings , i believe it was therippa who told me to change the settings and give it some lift , i set it to 3mm and no more problem. So depends on your settings it will go up and down both during a print.

Hey KN4UD.........
Good idea for tightening up the nut on your lathe chuck. If mine are like that, I'll do the same on my lathe. I had a small cnc mill a few years ago that had a brass lead screw nut that was split on one side and had a screw going from one side to the other on the bottom of the nut. If you started to get back lash you could just tighten the nut a little.

Do you have pictures of your z bearing support you made?

OK, I now understand that you could have movement up and down. Hmmmm, maybe it would help MY stringing. Gotta try it. At the rate I'm using this printer, I probably will have those threaded rods worn out soon anyway. I guess I better start printing the Z carriage pieces for the lead screws!

Do you have pictures of your z bearing support you made?

[i.imgur.com]

This is a picture of the one I done in PETG. The ones I am using now are ABS. I gave some thought of making a split nut like the one you are talking about, It has been 20+ years since I cut a multi start internal thread (lol) so I just settled for crimping it. It is still good and checking it with a dial indicator it only has .0015 inch slack. I am going to do a remake of the upper support and use a 5mm bearing in it too and make a solid 5mm cupling from the motor to it to completely do away with the flex and sping of the factory cupling and the 5x8 one. I probably is not necessary but hay I love tinkering with this thing and trying to make it better, its fun. I added a 4th bearing to the bed because I could feel some twist in it. I have learned with these bearings to order alot of them and go through them to find the best ones last time I got 6 out of 10 that I found usable.

I am going to try and make pictures of the unit tomorrow and post them. I am 2hours into a 6hour print for the grand kids right now.

That is a pretty awesome set up upgrades therippa! Could you point me to details on how to install/implement the auto-leveling? I saw a post way back where you linked to a thread/diagram in German, but that was not enough for me to follow. I'd really like to add this feature...

First you need to get an aluminum build plate, and this sensor

Then you need to build a circuit that handles the switch connection, since the probe runs on 12v, but the RAMPS board needs 5v. It's just this guy...



You need to order a 4k7 resistor and a 10k resistor, some terminal blocks, and a PC817 optocoupler, and wire it as it is in the diagram.

Once you get it all together, you can follow Tom's video on adding autoleveling/autotramming.

I bought everything I needed for auto tramming, however it doesn't appear I am running the correct Marlin Firmware!?!? What version are you running??

Man I am really wanting to print this but no matter how I try I cant figure it out. I have split it into parts with cura but I cant figure out the best way to print it.

This

How about split it down the center of the long dimension and glue the two pieces together.


Newbie with Folgertech 2020 i3.

Okay, I'm stuck...again :-(

I updated the firmware and uploaded it.
I followed Tom's guide to test the sensor and make sure the firmware was working properly (printer homes using the probe with no problem).
I give it a G29 command but nothing happens!?!?
I checked and rechecked the firmware, all of the auto leveling code matches yours except two things, the grid pattern (mine is different due to my sensor mount-left of the hot end in X-Axis) and I deleted the comment on:
#define ENABLE_AUTO_BED_LEVELING (your firmware has this commented out).

Any idea what I might be missing!?!?

Thanks,
Sonny

FYI: I did a cut and paste of the Auto Level portion of your config file, I did not want to upload the full file as I didn't want it to have to change other settings I had already tweaked...

I'm on the fence with this one. Clearly you are one of the more knowledgeable gurus here so I respect your opinion. The Z axis is the least used axis as far as cycles go. Yes, movement must be accurate to have accurate layer thicknesses. However, the lowly threaded rod, once calibrated, should yield accurate movement. The X carriage and extruder assembly all hang on the Z threaded rods, so there's no backlash or looseness there since the nuts are always being pushed down against the threads. What are the real advantages of using the lead screws other than it looks more professional?

You are only thinking about one direction. You get backlash when you axis (Z for this instance) changes direction. In the beginning the nut and threaded rods will probably work fine as they are still tight. But over time the rod and nut will start to ware and this is when the backlash issue will happen. Thats why people made a double nut with a spring for the z axis like this one on thingiverse, z-anti backlash. Plus this is a kit printer. By improving it we get a better machine and more knowledge. Plus its just plain fun to tinker. Speaking of tinkering, how is TINKERCAD working for you?

I understand that when you change direction, the backlash comes into play BUT the Z axis never changes direction during a print. It's always moving up a step at a time. At least with the things I've printed.

Oh, yea, TINKERCAD is awesome for an easy to use program. I'm using it every day to modify things, combine things, invent new things, change wording on trophies for the grand kids, and even today I printed out a power window knob for the son's Jeep! I only wish it had the ability to easily chamfer or radius edges. Even rounding the corners of a square is a chore. There's no template for that. To that end I'm also learning AutoCad's free 123Design. I've used AutoCad from day one but never got into 3 D.

I fully understand the urge to tinker and improve. I'm a sucker for anything technological. Always have been for 72 years. smiling smiley I can program PLC'S in ladder logic and code, can program robots, design products, fly RC airplanes (60 years doing that), enjoy woodworking, am a part time potter and enjoy working on cars. Other than that, I just sit around and do nothing!!!!! hahaha I'm sure I'll have those lead screws on here whether I need them or not just because they are cool and it gives me an excuse to print some more 'stuff'. My printer has been going since 7 am printing 'stuff' for Halloween plus an X motor cooling shroud I designed with TINKERCAD. That's the only motor that gets hot and it has the lowest voltage by far. I read the specs on our stepsticks and it appears that they can only put out a max of 1.5 amps so anything goes. That's assuming FT hasn't changed them.

Was it you that wanted pictures of the latest version of the FT extruder drive? If so, I'll get some tonight.

I too have been using 123d. But I find myself going back to tinkercad for easy tasks. I need to stick with 123d until I find it easy.

Have you tried Fusion 360? They really do a good job updating the basic core of 123D!

That is a pretty awesome set up upgrades therippa! Could you point me to details on how to install/implement the auto-leveling? I saw a post way back where you linked to a thread/diagram in German, but that was not enough for me to follow. I'd really like to add this feature...

First you need to get an aluminum build plate, and this sensor

Then you need to build a circuit that handles the switch connection, since the probe runs on 12v, but the RAMPS board needs 5v. It's just this guy...



You need to order a 4k7 resistor and a 10k resistor, some terminal blocks, and a PC817 optocoupler, and wire it as it is in the diagram.

Once you get it all together, you can follow Tom's video on adding autoleveling/autotramming.

I bought everything I needed for auto tramming, however it doesn't appear I am running the correct Marlin Firmware!?!? What version are you running??

Check my signature smiling smiley

You made it too easy ;-)

Thanks!!!

Okay, I'm stuck...again :-(

I updated the firmware and uploaded it.
I followed Tom's guide to test the sensor and make sure the firmware was working properly (printer homes using the probe with no problem).
I give it a G29 command but nothing happens!?!?
I checked and rechecked the firmware, all of the auto leveling code matches yours except two things, the grid pattern (mine is different due to my sensor mount-left of the hot end in X-Axis) and I deleted the comment on:
#define ENABLE_AUTO_BED_LEVELING (your firmware has this commented out).

Any idea what I might be missing!?!?

Thanks,
Sonny

FYI: I did a cut and paste of the Auto Level portion of your config file, I did not want to upload the full file as I didn't want it to have to change other settings I had already tweaked...

You need to upload the full firmware from my project for autolevel to work (stock folgertech doesn't support it), so use something like BeyondCompare to merge your specific config.h settings in with mine. Also, for G28 (home) to work properly, you're going to have to move your x-axis to the left side, as the autolevel-version of G28/home doesn't support x-endstop being in the max position. You can see what changes I had to make to config.h in my personal branch - [github.com]

Man I am really wanting to print this but no matter how I try I cant figure it out. I have split it into parts with cura but I cant figure out the best way to print it.

This

How about split it down the center of the long dimension and glue the two pieces together.

I don't have a way of doing that since I cant seem to figure out a way to load it into inventor. Anyone want to split it down the middle?

You can import the stl into sketchup and do it with that.

Yep, why go anywhere else? You won't find that any cheaper plus you're supporting a great US company that's treated us very well. No, I don't work for them! They just gave me great service when I most needed it.

Ok, so I ran through this several times and settle on 96.8. I decided to try a 20 mm square cube and the attached photo is the result of the print. It's close to 20 mm square, if I can smooth out the print. First photo should be top and sides, second is bottom and sides.

That's absolutely horrible looking! Your print should look like this >
[attachment 64066 test_cube.jpg]

Hopefully, someone with more experience than I can pinpoint what's going on. To me, it looks like you've maladjusted something or many things in your slicer program. Or your layer thicknesses are 3.0 instead of 0.3? Or you have never adjusted your nozzle to bed clearance to 0.1mm?

When you were testing your extruder calibration, did you see large changes in how much it fed each time you tested the 100 mm? Maybe it's not feeding correctly or your voltage to the stepper motor is wrong. Clearly something is majorly wrong.

I'm starting to think I missed some steps somewhere. Anyway I played with it last night and attached it some photo of the result. left to right: slack in the belts, turn up with estep and adjust temp, printer clog, played wit estep and temp again. Now I got the firmware from from github so is there anything special I show be aware of with it? Reason being is I had to turn up the estep to 165 to get the last cube in the photos.

I'm going to jump in and say "slow down" . Take one step at a time. The first thing I would do if I were you would be to back up. How tight are your belts? Make sure the pulleys are tight on the stepper motor shaft or it will skip and you will lose steps. Then after you think that is ok, take a digital caliper and check your axis's. And recheck them. Make changes in your firmware like you did on the extruder. Get them as close as possible. Then try a simple 20x20 cube.

Hi kn4ud, rippa,

You guys mind sharing some slic3r tips on PETG? I see you mention lift.. did not try that, going to do it myself.

I am having stringy hell right now smiling smiley

Sonny I have auto-level in place now via servo.. love it.. let me know what I can do to help.
Don't even bother trying to get the 5v bus on the stock folger to power the servo as-is. You'll need to wire up a separate 5V power supply to the ramps board for it.
