Duet crashes just after starting

@dc42 you mean like print_start and speed_printing/speed_probing? yes, those

dc42

@marcfischer please share those macros.

MarcFischer

Print_start:

; Start a print V2.1661

;G29 S1
M220 S100 ; reset speed multiplier
M221 S100 ; reset extruder factor to 100%
M290 R0 S0 ; clear babystepping
G10 P0 S235 ; set temperature

M83 ; set extruder to relative mode
G21 ; set units to mm

T0 ; select tool 0

G32 ; level the gantry while everything is hot

G29 S1 ; Load previously probed bed mesh (optional, use only if you know your bed is warped)

;M98 P"/macros/print_scripts/goto_bed_center.g"
G28 Z ; Final z height adjust

G1 X10 Y30 Z1 F5000 ; move z up little to prevent scratching of surface
G92 E0 ; reset extruder
G1 X10 Y30 Z0.2 F5000.0 ; move to start-line position
G1 X10 Y200.0 Z0.2 F1500.0 E15 ; draw 1st line
G1 E-0.05 F3600 ; quick retract
G1 Z5 ; go away from bed because of temperature
G92 E0 ; reset extruder
G21 ; set units to millimeters
G90 ; use absolute coordinates
M83 ; use relative distances for extrusion

setup_printing:

; called to set up current, speed & accel for printing moves

M566 X500 Y500 Z60 E8000 ; Set maximum instantaneous speed changes (mm/min)
M203 X18000 Y18000 Z3000 E15000 ; Set maximum speeds (mm/min)
M201 X2000 Y2000 Z250 E2000 ; Set maximum accelerations (mm/s^2)
M204 P1200 T2000 ; Set printing acceleration and travel accelerations
M913 X100 Y100 Z100 ; restore current to 100%

setup_probing:

M566 X900 Y900 Z20 E3600 ; Set maximum instantaneous speed changes (mm/min)
M203 X18000 Y18000 Z3000 E5000 ; Set maximum speeds (mm/min)
M201 X2000 Y2000 Z100 E800 ; Set maximum accelerations (mm/s^2)
M913 X60 Y60 Z40 ; Set reduced current for probing/homing to reduce damage

First file (Blue1) does probing, starts printing and resets after 1-2 minutes (tested twice, stopped at the same place)
Second file (Blue2) resets right away after i start it.

@marcfischer are you using a daemon.g file?

@marcfischer thanks. There is a known issue with M486 in RRF 3.3 when the number of objects on the build plate is >20. This is fixed in RRF 3.4beta1. We will probably do a 3.3.1 release with this and a few other fixes.

No

A, ok! That's why the big saturday print prints without problems, 12h..... only 16 parts.

dc42

@marcfischer a workaround is to tell your slicer not to generate M486 labels, if you can. RRF doesn't need them if the file includes object labels as comments. Or you could post-process all the M486 lines into comments.

MarcFischer

Ok, thanks. Weird thing is, they just showed up. But fount it in SuperSlicer:

Print Settings > Output options > Output File > Label Objects. When off, it doesn't make the M486 anymore.

Thnx for all help!
