Missing Steps - Cant Print SpreadCycle StealthChop tuning help

SputnikOC3d

seems as if the options are limited to stealth ON for homing only, then spreadcycle for all other.

Getting the code right for this appears to be the challenge now.

Wish I had the answer for ya buddy ... ANybody ? Bueller ?

So ive tried some more this evening, thought I had made some progress but still not great. I checked M569 P0.0 S0 V50
M569 P0.1 S0 V50 at 75mm/s for my motors to fall into line with my homing speed of 66.6mm/s, I can't say whether the bangs or what im calling micro bangs / thuds are still there as it sounds worse everywhere else... Thought's, help?

Layer shift / skipped steps??

X Axis

Drive 1 runs in reverse, active low enable, timing fast, mode stealthChop, ccr 0x00053, toff 3, tblank 0, tpwmthrs 50 (75.0 mm/sec), pwmScaleSum 10, pwmScaleAuto 0, pwmOfsAuto 112, pwmGradAuto 18, pos 584

Y Axis

M569 P0.0
Drive 0 runs in reverse, active low enable, timing fast, mode stealthChop, ccr 0x00053, toff 3, tblank 0, tpwmthrs 50 (75.0 mm/sec), pwmScaleSum 11, pwmScaleAuto 0, pwmOfsAuto 119, pwmGradAuto 18, pos 328

Home X ( Y is a duplicate) I had to increase the speed of "G1 X125 F5000 ; centre the head and set a reasonable feed rate" line as the final move sounded terrible at the end.

@carcamerarig could part of the issue be related to this:

@t3p3tony

Thanks for the link and trying to lend an assist. Myself and a few others are trying to get our heads around this issue with the OP. I have a new build that will use the Mini as well, and our friends with the 3H full board is lending a hand - but we just cant seem to get things working as they should.

Homing is sorted ... however; after we take him out of stealthchop via M569 D2 parameter after homing- hes still missing steps and getting layer shifts in very easy prints - no major torque stress - no blobs - not nozzle impacts - just infill moves.

There really has to be a better way to tune these .9* motors and these drivers - this nonsense has been going on for days now ...

Honestly I have no clue now, that thread went cold with no definitive outcome, I asked if the Gcode dictionary reflected the updated comments?

ctilley79

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?

droftarts

@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.

Ian

ctilley79

@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.

Argo

Duet WifI = TMC2660
Duet 3 Mini = TMC2209

0.9 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.

gloomyandy

@carcamerarig Still doesn't work for me.

ctilley79

@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 ?

carcamerarig

@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.

ctilley79

@carcamerarig A method that doesn't require an oscilloscope would be nice.
