I am really bad at GCODE. REALLY bad.
So I need help to set my heat bed to 70 C, then wait 5 mins, then to 60 C, then wait 5 mins, then to 50 C, 5 mins etc. until I get to 20 C.
It would be put in the box of after print gcode stuff at the last page of slic3r.
Can anyone help me and write this stuff out or just give me the line of 70C wait 5mins, I can figure the rest out by myself
Thx.

The best way, I can think of is to keep the printer busy for 5mins until you change bed temp again.

M190 S70          ;set bed temp to 70C
G1 F2000 X0     ; moxe x axis to zero at normal speed
G91                   ; set to relative positioning

G1 F10 X50       ;moves x-axis 50mm at a speed of 10mm/min = 5min pause
M400                 ; tell the printer to wait until the move has ended
M190 S60          ; set next temperature

G1 F10 X-50       ;moves x-axis minus 50mm at a speed of 10mm/min = 5min pause
M400                 ; tell the printer to wait until the move has ended
M190 S50          ; set next temperature

G1 F10 X50       ;moves x-axis 50mm at a speed of 10mm/min = 5min pause
M400                 ; tell the printer to wait until the move has ended
M190 S40          ; set next temperature

; repeat until done

G90                  ;set to absolute positioning
G1 F2000         ; set speed to normal values

Hmm, just tested the script on my Prusa and it only seems to work when started from SD-Card.
Trying to "print" this via Octoprint/USB port ended in a timeout error. Seems the M400 command blocks everything.

I've attached the script in case someone want to try it. ( or improve it smiling smiley

)
