Missing Steps - Cant Print SpreadCycle StealthChop tuning help

dc42

@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, 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

Yes. Would you be able to tell if there was a problem if you air-printed a few cm above the bed, to avoid the risk of nozzle hits?

Shall i disable the forcing of SpreadCycle too ?

No, I'd rather resolve any issues running in spreadCycle mode before we look at other modes.

Initially I could also reproduce the issue at will. I won't be able to confirm for a couple of weeks as I no longer have a working Mini5+ to test with (amazingly my replacement was dead on arrival, this is being handled separately by @T3P3Tony I believe).

This will of course be one of my first tests once I get a working board in my hands again.

Loaded the Beta 3.3 beta 2+2 as per your indication

spreadcycle forced (D2)
mesh active

it apperas to be working fine
i made two prints: one 1st layer and 4 corners prints, no issues of sort

thanks

Thanks for the report! It may be that fixing the stepper driver comms timeout errors has fixed this issue.

I have just added a new M569.2 command to RRF so that if this issue still occurs, we can read the actual values of the stepper driver registers.

carcamerarig

@dc42 Fairly productive day with Ian using the new fw as you know, we couldn't replicate the bangs (large travel bangs causing layer shifts) and Ian explained the mini bangs during infill are the switchovers (these never caused layer shifts, mini bangs was just how described them) Had some fun and games with homing but I think we've got something like with maybe just a bit of fine tuning.
Need to check through the config later / tomorrow and see if I can rattle off a couple of prints, fingers crossed no bangs I did mention yesterday under the 2+2 fw I couldn't get it to bang air printing. Only just back home so ill update later / tomorrow.

Ian and Dave thanks for the support both.

droftarts

@carcamerarig Yes, good day! Can you share a copy of your config.g and homeall.g? I forgot to get a copy, and I think it contains a good example of stealthchop tuning.

Ian

SputnikOC3d

@droftarts - any chance of elaborating on the mods and changes and focus of how to sort this ?

What did we discover was happening that was corrected ?
