3.2 beta 1 Freeze while printing

Veti

can you post your config?

dc42

@Luke-sLaboratory, thanks. I suspect the problem is being triggered by the G29 S1 command in tpost.g, which involves fetching the height map from the SBC. Are you able to try printing with that command removed from tpost.g?

PS - if I am right, then you may be able to get the fault to happen more quickly if you put multiple G29 S1 commands in tpost.g.

@dc42 Still bugged out at about the same point, random toolchange. Unfortunately I hit M112 vs M122 for diag, so no gcode, but I took out the mesh correction as requested. Sorry for a late reply, took me a while to get back to the printer.

Hello,

I also encounter random freezes since the 3.2 beta 1. It happens in almost 1 out of 3 print.
I do a purge line at the beginning of each print with the following GCode:

M561	; Clear any bed transform
G28	; Home all axes
G29 S1	; Grid compensation

T0      ; Select tool 0
M116	; Wait for tools

; Purge line
G1 Z0.2
G1 Y2 X25 F15000        ; move out of build volume
G1 X150.0 E24 F1200     ; finish purge line
G4 P4000	        ; Wait to let the plastic cool a little
G92 E0                  ; reset extruder position to 0

And it freezes right after doing the purge line. It might be an issue with the heightmap loading as suggested by @dc42 because effectively I normally receive the "Heightmap loaded" notification just after the purge line and when my print freezes I don't have this notification.

dc42

@Lucas, are you also running Due 3 with attached SBC?

Lucas

@dc42 Yes a Duet 3 with a Raspberry Pi 3 attached

dc42

Thanks. Please post a M122 report taken when it has frozen. Also please post some more lines from your GCode file.

Which is the last GCode line completed when it freezes?

Lucas

@dc42 Here is the M122 when the printer is frozen:

The GCode I posted earlier is my "Before Print" Gcode and it's all of it. The next GCode lines are the lines from the print itself but I think that the last completed line is the line 12 of my "Before Print" Gcode because the Tool is still positioned at the end of the purge line and the extruder isn't reset to position 0 as it should be on line 13.
Also I said in my previous post that I didn't have the "Heightmap loaded" notification when it freezes but it was a mistake I do have the "Height map loaded from file heightmap.csv" notification before the freeze.

I'm getting the same intermittent freezing. Also seems to happen during toolchange procedure. Sometimes before toolchange, sometimes after.

@Luke-sLaboratory, please try firmware 3.2beta2. We have made major changes to the way communication between the Duet and SBC is handled, which may resolve this.

Luke'sLaboratory

@dc42 WHOO!

apt-get update && upgrade are in my future! I'll give it a chooch and see what happens

Luke'sLaboratory

@dc42 I'm very upset right now - you failed to mention the more important upgrade - ON SCREEN KEYBOARD!!!!!!

Luke'sLaboratory

@dc42 Alright - 3rd Reply - Did Another print, no fail on tool/mesh load! great! However - got a push() Stack overflow error in my console, M122 below it cancelled the print, and cooled down the stuff, which was very nice of it

M122
