    • IceSL printer profile

      I recently stumbled uppon IceSL, which looked very interresting.

      The included printer profiles did not generate G10 and G11 for firmware retraction, so I needed to create a new profile. Maybe this is of use for someone else, so I put it on github: https://github.com/darookee/icesl-duetwifi.

      I use scripts and macros for a lot of things, so instead of generating a start and end g-code the generated g-code file relies on macros stored on the Duet. This has the advantage that you don't need to re-slice a model for everytime you change something in your start and end procedures. It also just generates the code to set the bed temperature, as selecting a tool with Tn will heat the tool up to the temperature set with G10, in combination with the filament feature of the WebUI the files generated with this profile are almost material independent.

    • RE: Tuning the Precision Piezo to not trigger on every move

      @djdemond No Problem! Unfortunately I gave up for now, as I could not get it to not trigger before probing or even while probing, but not yet touching the bed as it needed to be very sensitive to trigger when the nozzle touched the bed.
      I'm planning on rebuilding my Z and getting rid of the springs on the corners of the bed. Do you think this could help with triggering at a lower sensitivity?

    • RE: Extruder motor stuttering/skipping

      The print just finished. It occasionally clicked and clacked a bit, I tried loosening the screw a bit more, but that does not do anything. But I guess it's not a Duet problem. Thanks for the help! 😄

    • RE: Extruder motor stuttering/skipping

      I disconnected the motor and tried turning on the black gear. It was a bit hard to move. I disassembled the extruder body and tried turning and it moved freely... So then I reassembled everything and did not tighten any of the screws, than turned the gear and tightened one screw after another. When I tightened the one through the bearings and gear it started to get harder to turn, than I unscrewed it a bit. I'm currently heating the printer up. I checked the screws multiple times but never noticed this... gnah 😐

    • RE: Extruder motor stuttering/skipping

      The pinout seems to be the same for both motors and cables. The motor that is currently installed was installed with the same cable for about one year, but with an MK10 extruder. Now that is 'in' the Titan Aero it is giving me troubles. Also the Titan Aero with the pancake motor was working fine for at least a few days. Could this be a problem with the bearings (that E3D had a while ago...)?

    • RE: Extruder motor stuttering/skipping

      Yes, well. I already swapped the cable, and that did work at first. As for the motor, I guess the E3D pancake motor is busted, I did not try it again after it didn't work with the new cable, the other motor I'm currently using worked flawlessly in my old extruder assembly and worked fine until I installed it on the Titan Aero with the new cable and printed for a while (didn't work with the old cable).
      I'm running on 12V. The E3D pancake motor is a 0.9° 12V motor rated at 1400mA, the other motor is from an 'old' Wanhao i3 and the specifications are not clear, but it is a 1.8° 12V motor, and it ran for about 1 year at 1200mA without problems.
      My settings are as follows:

      M201 X2000 Y2000 Z100 E250
      M203 X18000 Y18000 Z300 E1200
      M92 X80 Y80 Z400 E418

    • RE: Extruder motor stuttering/skipping

      It was connected to E0, after your post I moved it to E1 and added M584 E4:3 to my config, before any M906 and M350 commands. Then restarted the printer. (It was also powered down while swapping the connectors).

    • RE: Extruder motor stuttering/skipping

      Thanks for the suggestion. I just tried it, but it also does stutter. Just to confirm, M584 E4:3 just remaps the driver internally, the output still is the on marked as E1 on the board?
      Yesterday I did try E1 with reconfiguring the tool (M563 P0 D1 H1), also with stuttering. 😕

    • Extruder motor stuttering/skipping

      A few days ago my Titan Aero started stuttering while extruding and retracting. After a lot of troubleshooting I was conviced that it was a bad cable, but that does not seem to be the only problem.
      I used the pancake motor that came with my Titan Aero and it was running successfully for a few days after finaly installing it on my printer. Then one morning when I wanted to change filament it startet suttering a bit while retracting. I didn't think much of it so I inserted the new filament and startet to print. While printing it stuttered more often so I cancelled the print and got on with the troubleshooting. Trying higher temperatures, doing cold pulls, pushing the filament manually,... I could cofirm that it was not a clogged nozzle. I then disassembled the extruder and tried to run the motor on its own which resultet in more stuttering and ended in the motor only stuttering and not moving at all. I then tried the motor from my old extruder, which also did stutter. I then tried another motor driver (was using E0 exclusively before that) but it also stuttered. Than I used another motor cable and the motor turned without a problem. So I reassembled the Titan Aero, first with the pancake motor, but it started stuttering again, then with the other motor and I finally got filament extruding. I then tried a print, not bothering with finetuning the extruder steps, just modifying it for the 1.8° stepper instead of the 0.9° pancake stepper. The print started fine, but after a few layers it began to stutter again. I cancelled the print, tried again with higher temperatures and slower extrusion speeds, but it begins to stutter more frequently again. I now stopped everything because I don't want to damage another motor.
      I'm at a loss. It's not just the motor, it was not just the cable, it's not a clogged nozzle and it does not seem to be too high pressure on the motor shaft. What can I look for now? I also tried adjusting the motor current (was set to 1200mA for my old extruder, which I also used with the Titan Aero pancake motor without problems, that one is rated for 1400mA), but that doesn't do anything, either...

      I need help, please 😕

    • RE: Tuning the Precision Piezo to not trigger on every move

      I did a bit more testing and foud out that the piezo will trigger, just much later than I expected. And much less reliable. I did G29 and got this:
      Gnah

      After moving everything around one lead of my piezo broke and I had to replace it, but just had 27mm discs. I stuck one below the lowest screw of the mount and got this G29 result
      YAY

      Now I'm happy...

    • RE: Tuning the Precision Piezo to not trigger on every move

      After fiddling a bit more I glued the disc in place, this got rid of the constant triggering when the fan is turned on (YAY!).

      Unfortunately I discovered that my design is pretty flawed. As I said the idea was that the bed touching the nozzle would pivot the 'arm' with the triangle on top around the whole in the bottom to press the piezo. Touching the bottom of the motor mount does just that. Touching the coldend part of the Titan Aero does it, too. Touching the nozzle doesn't…

      I also found that the top of the triangle is touching the solder point on the piezo, I'm trying to file it down a bit so that it does not touch it anymore and see if that does anything...
