does not completely finish the last layer of the print 3.5.0-b4

@Diamondback that's what I want to know. It may have had the same cause as the issue I was able to reproduce and fix.

Ah, sorry, wrong thread I meant to post in the filament monitor one...

@dc42 Can you elaborate what sort of condition lead to the SD print not finishing properly? Can you tell what it would do "instead"?
Would it just ignore all the rest of the file? Or just parts of it? What I can imagine given the behavior I saw is that RRF ignored the last few lines of actual extrusion but then executed all the management stuff afterwards (tool deselection, toolhead parking etc)
In that case the headcrash would happen due to the nozzle still being in the middle of the print and Z not being lifted...
Is that something that seems plausible?

I really want to understand this issue and help debug it but I'm not really fond of destroying another Revo nozzle...

@dc42 More info on this from my side. What I have been seeing appears to be the combination of two issues.

Not finishing of the extrusion bit of the print file
Some weird crashing/stalling movement issues after pausing and unpausing the print

The first issue seems to be new with RC1, but the second issue also just happened to me on beta 4. I will try to actually replicate what it's doing, maybe without a tool or without a nozzle or something. It's kinda scary, but I don't fully understand what exactly is happening. The printer makes very loud nosies as if it's stalling/crashing into something, but ultimately it somehow ends up moving in the right places. I haven't been able to actually see what it's doing, I only heard it a couple of times and saw the end result. I will try to film it or something and then make a new thread about that.

@Diamondback A little bit of info from my case:

Not finishing of the extrusion bit of the print file - I had this problem with 3.5 beta versions too, it was solved with RC1.

2.Some weird crashing/stalling movement issues after pausing and unpausing the print - I had crashes for no reason at the very end of the print, with beta versions (there was no pause).

@Diamondback have you tried the new firmware at https://www.dropbox.com/scl/fo/tjznycpk7bv7sj71p0ssl/h?rlkey=096p4nvgmigyrb20jj8olg3wu&dl=0 yet?

@dc42 So far no issues with not finishing the print with this build.

@Diamondback thanks for reporting back.

@dc42 Some more prints done, nothing new to report, all working fine.

@Diamondback thanks, I'll flag this as solved.
