Missing Steps - Cant Print SpreadCycle StealthChop tuning help

carcamerarig

@dc42
Sorry that was Home in stealthchop M569 P0.0 S0 V0 M569 P0.1 S0 V0.
Send M569 P0.0 D2, M569 P0.1 D2 for the print after homing.
M122 after each incident and M569 P0.0 / 0.1 to confirm spreadcycle.

dc42

@carcamerarig, please can you post the results of M569 P0 and M569 P1 next time as well the M122 report, to confirm the driver parameters.

carcamerarig

@dc42 top of the 1st of the 2 report posts??

dc42

Ah I see them now. What were the "incidents" ?

carcamerarig

@dc42

Travel bangs the same as before between models and mini bangs on infil 15%
I’ll upload video again but it takes a while

dc42

@carcamerarig, thanks. Please post your config,g file too.

@carcamerarig, it seems to me that you can reproduce this issue at will. Please can you try the following (still in spreadCycle mode):

Install the firmware at https://www.dropbox.com/sh/qlucwfda9257p7u/AABoJogMNT-9P0kefE2W_0bxa?dl=0. After the problem occurs, get a M122 report. This firmware includes an additional diagnostic line.
Test whether a gcode file containing a simple repeated loop such as the following provokes the problem:

while true
  G1 X300 Y400 F24000
  G1 X0 Y0

Adjust the G1 movement limits and speed according to the capabilities of your machine.

Test whether increasing XY microstepping from the default x16 to x64 makes the issue happen more or less often.

Thanks in advance!

carcamerarig

@dc42
so I ran the gcode loop to replicate my travel speed 180mm/s

while true
G1 X150 Y150 F10800
G1 X50 Y50

Homed in stealthchop, M122 and M569 P0.0 + M569 P0.1 to verify, sent M569 P0.1 D2. M569 P0.0 D2 to set spreadcycle, M569 P0.0 + M569 P0.1 to verify. Ran the loop but could not get the bangs to replicate.

@carcamerarig. thanks. Please try your original print file with this firmware. Post a M122 report after any occurrences of this issue.

carcamerarig

@dc42 What mode?

oc_geek

@carcamerarig thanks for your efforts. If i may add one bit ...in my case it was mesh enable to create major issues (axis shifts) .
Did you run with or without mesh ?

dc42

@carcamerarig said in Missing Steps - Cant Print SpreadCycle StealthChop tuning help:

@dc42 What mode?

Please use spreadCycle mode until there are no problems when using this mode.

carcamerarig

@dc42 I can't actually get it to home now in this fw...

Argo

Homing does work for me with this compiled version and the timeout issues seems solved though it did not lead to any issues with my printer.

@argo - No Bang Bang ?

Argo

@sputnikoc3d

Nope, never had issues with bangs or skipped steps.
But also had many timeouts in the M122 report which are gone now.

@oc_geek said in Missing Steps - Cant Print SpreadCycle StealthChop tuning help:

@carcamerarig thanks for your efforts. If i may add one bit ...in my case it was mesh enable to create major issues (axis shifts) .
Did you run with or without mesh ?

@oc_geek, do you still have problems with bangs or layer shifts, using more recent firmware such as the one I posted at https://www.dropbox.com/sh/qlucwfda9257p7u/AABoJogMNT-9P0kefE2W_0bxa?dl=0 ?

More generally: is anyone else apart from @carcamerarig still having this issue, using this firmware?

oc_geek

@dc42 hi i have not tried that version yet
IF i disable mesh i can print with spreadcycle forced

Are you suggesting to try the fw AND enable mesh to see how it goes (it scares me a bit...tbh as i already had two noozle hits on bed...)
Shall i disable the forcing of SpreadCycle too ?

thanks
