@carcamerarig Your video (posted earlier) does not seem to be accessible, at least it isn't for me.

should be I just checked, links set to anyone with link, anyone else not able to see it?

@carcamerarig could part of the issue be related to this:
https://forum.duet3d.com/topic/21108/stall-detection-on-duet-3-miniHonestly I have no clue now, that thread went cold with no definitive outcome, I asked if the Gcode dictionary reflected the updated comments?

I've tried helping @carcamerarig on this issue, maybe I can give my take on what's going on. We believe we have homing with stallguard figured out, but that's not the main issue.
The issue is during fast moves, the printer will stutter causing a thump sound, resulting in a layer shift. The nozzle is not hitting the print or other obstruction.
I thought originally this may be caused by the switchover from stealtchop to spreadcyce. However forcing the machine into spreadcycle after homing did not alleviate the issue during a print. @carcamerarig Can you post a link to the video showing the problem?

@ctilley79 @carcamerarig does it still do the thump with mesh bed levelling disabled? Could be a slow Z axis movement is stopping X Y movement.

@droftarts He has a prusa type machine similar to mine and mine doesn't behave like this. We both have similar acceleration and jerk settings for Z although he does keep his Z in StealthChop full time. The only ohter difference is my machines are Duet WiFis.
-
Duet WifI = TMC2660
Duet 3 Mini = TMC22090.9 motors + TMC2209 are difficult to set up. Our Marlin neighbours are having similar difficulties with 0.9 motors, TMC2209 and StealthChop.
Imo it's not worth the hustle. Use 1.8 motors, set V to 0 (no hybrid mode) and happy printing.
-
@carcamerarig Still doesn't work for me.
-
@argo we've switched entirely to spreadcycle and the issue remains.

Why cant this board be easily tuned and configured to run with .9* motors while other - cheaper alternatives and lessor developed FW can?
This really shouldn't be this difficult. Perhaps 2209 drivers werent the best selection for the Duet mini boards ?
-
@dc42 Could you, or task somebody to do it, create a step by step guide from start to finish for this ( configuring then printing ) an idiots guide that a monkey could follow please. I'll pay for it to be done if you can organise it.
-
@carcamerarig A method that doesn't require an oscilloscope would be nice.
-
Acknowledgement of a potential issue and a working fix would be nicer.
There seems to be issues around he spectrum of users with the TMC2209's and .9* stepper motors.
That being the case I dont at all see the attraction to these 2209 drivers ... All this for sensorless homing ?
-
@sputnikoc3d
No. Sensorless homing is working fine while homing. He's only in StealthChop for homing currently. We switch back to SpreadCycle after homing. He's having the thumping/banging issues in SpreadCycle as well which is bizarre. SpreadCycle normally doesn't require tuning for it to operate on a variety of different motors. You might get more noise with different brands, but the stutters and resulting in layer shifts with SpreadCycle is stumping me. I don't see why the 2209 in SpreadCycle mode should vary among the different Trinamic chips regardless whether it's a 2660, 2209, 2208, or 5160. -
@droftarts - have any other insights to this issue ... any known successful configurations ?
Missing steps in SpreadCycle on very easy print geometry and conservative travel speed moves/settings.
Eliminated MANY potential aspects - but its starting to seem that these 2209's just dont like to play nice with LDO .9* motors

To be fair im at the point where im "hacked off" with the lack of input or support, 6 fairly knowledgable people located around the world all in different timezones have put an insane amount of time and assistance into trying to get this issue resolved to no avail... A simple procedure to follow to setup motors would pretty much alleviate this?

Forced Spreadcycle settings, same thump/bang persists, StealthChop for homing only.
