[BFW-6259] [BUG] Crash leaving tool dock

[Tillquist]

Printer model

XL Multitools

Firmware version

6.2.0-alpha2

Upgrades and modifications

No response

Printing from...

Prusa Connect

Describe the bug

I don't quite know how to describe the error, but watch the video and you can see that the print head moves in the opposite direction than it should normally do when starting to print.

Same gcoder runs fine on firmware 6.1.3 without anything.

Fail with 6.2.0-alpha2 firmware

How to reproduce

Same error the 2 times I have tried 6.2.0 alpha 2, I experienced the same error on 6.2.0 alpha 1

Expected behavior

No response

Files

No response

Hey, to be clear - this is at the beginning of a multitool print?

@Tillquist be careful, you seem to have publicly posted your address

@Tillquist I'm failing to reproduce this. Could you please:

• Send me the gcode that's causing this?
• Show me your dock station offsets?

@Tillquist seems like github doesn't support email attachments.

Here it is Download here

The same file runs perfectly fine on firmware 6.1.3 without problems and it is made in Prusalicer 2.8.1

But the link is only valid for 3 days from now

[CZDanol]

@Tillquist damn, I thought I have downloaded it, but apparently I forgot. Sorry :( Could you please reupload?

[CZDanol]

Can I also ask for the exact tool mapping you used?

I don't quite understand what you mean?

Mapping gcode filaments to physical toolheads. The initial sequence suggests that filament 1 is mapped to tool 4.

[CZDanol]

Thanks, and the gcode reupload? Sorry :(

[Tillquist]

Download Gcode here

Okay, I was unable to reproduce it on my XL on 6.2.0-alpha2 with your file, but I still believe I have found the cause of the crash and I have a different reproducer. It's down in the motor control code for which we have @wavexx who's expert in that, so I will try passing the issue to him.

[Tillquist]

Tanks 😊👍

[CZDanol]

Okay, we've been hopefully able to fix the issue. Please be so kind and try the next 6.2.0 candidate when it comes out and report here if the issue is resolved for you.

Thank you for your cooperation :)

[Tillquist]

I do that 👍
