Missing Steps - Cant Print SpreadCycle StealthChop tuning help

[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

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

We all hope it will be history by then

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 ?

@droftarts Could you post links with a short description to explain how we configured the stall detection, sensor less homing and the trinamic flowchart. The way you explained it made more sense than the dozuki.l and I think many would understand it better.

[droftarts]

@sputnikoc3d We spent a large part of the day testing @carcamerarig Mini 5+ setup. I was able to reproduce the 'small bangs' he talked about, by setting the changeover from stealthchop to spreadcycle to around 32mm/s, and it was particularly noticeable on gyroid fill sections of the test print, just like his video. If set to one or the other mode in config.g, by using M569 D(2 or 3) parameter, it stayed in the set mode and did not bang (was not using stall homing at this point, so did not need to change M569 parameters after power on). I was unable to reproduce the large bang in either mode with the latest firmware (14/4), or in 3.2.2. I ran out of time to test 3.3b2, but have set up my machine to try it out when I get the chance.

Also tested movement with bed mesh on, and with high jerk (900mm/min or 15mm/s) but didn’t push acceleration, which was set at 1500mm/s^2.

I recommended and setup for him to use stealthchop all the time, as the printer was happy to run at up to 300mm/s in stealthchop. I spent some time setting up what I regard as a good stealthchop tuning series of commands, and tuning the stall homing, which was pretty finicky to get right, and I'm still not 100% confident with.

I moved the M915 stall setup to homeall.g, and the stealthchop tuning commands (see posted homeall.g). It follows the recommendations from the Trinamic datasheet; see page 35 and 36 here https://www.trinamic.com/fileadmin/assets/Products/ICs_Documents/TMC2209_Datasheet_V103.pdf#page35
If anyone has more questions about this, please do ask, though it may be a couple of days before I get back to you.

I have set up my printer now with 24V and motors that are very similar in spec to the LDO 0.9 motors. I ran a quick test in stealthchop, with the latest firmware (14/4) and found motors quiet and no banging. In our testing today with the latest firmware, we had no driver errors reported by M122.

Kind of annoying we couldn’t replicate the big bangs today, but maybe switching to an older 3.3b2 firmware will provoke it.

If anyone wants me to test a different setup eg with stealthchop/spreadcycle changeover, please let me know.

Any other questions, please ask and I’ll get back to you when I can; I’m a busy family man, as @carcamerarig experienced today!

@oc_geek please post config.g. Looks like you have a low changeover speed to spreadcycle, does it mostly print in spreadcycle?
