  1. I, too, noticed the under-extrusion that you're talking about. The e-steps are calibrated but the flow rate could have been off. It was a frustrating time for me and this particular STL became my goto test piece, it would fail 100% of the time, and it's possible I might have rushed through some settings. I'm far from perfect/good calibration, which I'll be doing using your tool and Teaching Tech's acceleration tuning gcode generator. But in the meantime, I remembered what another MK4 user had told, he halved his X axis acceleration. I've done the same (M201 X3000.00 >> M201 X
  2. @GregValiant So, I got this tool working now with your instructions, and what can I say, this tool is like magic. The thing is, I'm not sure what data I should be gathering from it. For example, I set Accel to 500/500, Jerk to 10/10, speed to 150mm/s, and did the Nascar race (after qualifying). The printhead moved around smoothly. Is that the test? Should I be listening for strange sounds/skipping belts? If that is the case, and I find that anything over 500/500 and 10/10 cause the belts to skip, would I then do a M204 P500.00 R500.00 T500.00 M205 X10 Y10 My current accelera
  3. Update: I've upped the voltage for my stepper drivers to 1.15V (which is in fact the voltage that is recommended by users of my printer, it's just that with my bowden setup I was able to keep voltage at 1.0V). I am able to print at 60 mm/s issue free. I've realized that I've been a very silly boy. I somehow equated direct drive with greater print speeds and I don't think that is the case. My printhead is now roughly 140 g heavier and I'm expecting it to print at the same speeds (100-150 mm/s) as when the printhead was lighter. It was very silly of me to think that. @Gre
  4. Grrr I thought this issue was solved but not quite. Increasing voltage to the stepper drivers didn't help as much as I thought it did.
  5. @GregValiant Unfortunately, I couldn't figure out this tool. I only managed to getting it up and running. In any case, what should I do in theory? I know that the skip always happens along the y-axis, so should I change the Y jerk setting? Or is it something else? I just don't know where to start. Here is the relevant output from M503: Recv: echo:; Maximum feedrates (units/s): Recv: echo: M203 X500.00 Y500.00 Z6.00 E30.00 Recv: echo:; Maximum Acceleration (units/s2): Recv: echo: M201 X3000.00 Y2000.00 Z60.00 E10000.00 Recv: echo:; Acceleration (units/s2): P<pri
  6. @GregValiant I'm willing to boot into Windows for this! Thanks!! I will report back my results. Thanks again!
  7. The layer shifts are occurring along the Y axis. The following are 3 different prints of the same part. Note, most parts print just fine, this piece in particular is giving me a hard time but there is nothing with the piece/gcode itself, it's simply highlighting the underlying problem. I believe this layer shifting is happening because the printhead is heavier now and getting it moving from a standstill is difficult. I'm going to use Teaching Tech's calibration page but I would appreciate some guidance. In the meantime, I'm going to do a print a reduced Print jerk setting in
  8. Got it. I think it's best if I just print these pieces separately, as in separate gcode files. I just thought that this was a bug. Thanks.
  9. These pieces are obviously printing one at a time. I don't see why the cylindrical piece can't print first and then the blockish piece second. But I'm obviously missing something here. :/
  10. So it still might be possible to do. Will look into it further. Thanks!
  11. Anycubic Mega S I'm using a customized firmware that's based on Marlin 2.0.x.
  12. Hi there, I'm able to turn on the part cooling fan via M106 P0 S255 When I try the same command with P indexes from 1 to 5, the heatsink cooling fan doesn't turn on. The fan is functional because it does turn on automatically when the hotend is heated. Thanks!
  13. I just wanted to make sure I have this right. Let's assume the nozzle is touching the bed right now. The distance between the bed and the bottom of the rod is 32 mm. So my Gantry Height would be 32 mm? If that is the case then the Gantry Height is the vertical distance between the tip of the nozzle and the rod holding the printhead? Thanks!
  14. Also wanted to add, Octoprint connects just fine to the printer.
  15. @Torgeir @wjbdesign @gr5 @GregValiant All of you have given me much to think about. Thanks! I have done a few more things: -flow rate has been adjusted to 95%. I am confident in this value. -the gantry (I think that's what it's called; the thing that moves the nozzle up/down on the Z-axis) was slightly lopsided. It is now square. I will check it again after printing. -the print head does not wobble. I need to check a few more things that were mentioned. Will report back. Adjusting the flow rate has had a significant positive effect btw. To be
