Hi, I'm setting up filament change during print with M600 code. This is my filament-change.g :

;Change filament during print

M83               ; relative extruder moves
G1 E-10 F2000     ; retract 10mm of filament
G91               ; relative positioning
G1 Z5 F360        ; lift Z by 5mm
G90            	  ; absolute positioning
G1 X10 Y10 F3000  ; go to X=10 Y=10

G1 E-150 F1500 	  ; Retract 150mm of filament at 1500 mm/min
M400 		  ; Wait for the moves to finish

M300 S2000 P100   ; Beep
G4 P200
M300 S2000 P100

M300 S2000 P100
G4 P200
M300 S2000 P100
G4 P200
M300 S2000 P100

M291 P"Insert new filament" R"Filament change" S2

G1 E40 F100 	; Feed 40mm of filament at 100mm/min
M400 		; Wait for the moves to finish

M291 P"Press OK to resume" R"Filament change" S2

G1 E-10 F3600   ; retract 10mm of filament
M400 		; Wait for the moves to finish
M24		; Resume print

The problem is that M24 wont resume print. However, if I enter M24 in web console, or hit resume on LCD it resumes. I'm running version 2.02(RTOS) (2018-12-24b1) on Maestro.
Am I doing something wrong here ? Thanks.

Hello, is there 3D model for Maestro available ? I tried exporting from KiCad project, but I only managed to get bare PCB model. I'm designing enclosure to fit my 3D printer and this would help.

Thanks!
