Emergencyish stop
-
Just wondering if theirs any g code that can simply cancel the print. I know m112 rests the board but i wanted something just stopping a failed print.
thanks

Pause and Cancel?

yea mainly cancel. basically if i have a bad first layer i just want it to cancel the print and put some gcode to lower the z axis. -

The firmware finishes any moves left in its buffer, then it executes the macro file cancel.g if present, if the axes are homed and if a print is being cancelled. Otherwise it attempts to run sleep.g if present before all motors and heaters are turned off. It can still be sent G and M codes, the first of which will wake it up again. See also M0, M112.
If Marlin is emulated in RepRapFirmware, this does the same as M25 if the code was read from a serial or Telnet connection, else the macro file sleep.g is run before all heaters and drives are turned off.

I think the "before all motors and heaters are turned off. " covers the case where neither are present.
I don't use sleep.g myself, but I do have a pause.g and cancel.g
; pause.g ; called when a print from SD card is paused G10 ; retract filament G91 ; relative positioning G1 Z5 F600 ; lift Z by 5mm G90 ; absolute positioning G1 X10 Y10 F10000 ; go to X=0 Y=0; cancel.g ; Run when the print is paused, and then canceled. G10 P0 R0 S0 ; Set hotend temp to 0 M140 S0 ; Set bed temp to 0 M106 S255 ; Fan at 100 to cool nozzle and bed M220 S100 ; Set speed factor back to 100% in case it was changed M221 S100 ; Set extrusion factor back to 100% in case it was changed M204 P1000 T4000 ; Set printing and travel accelerations M566 X900 Y900 Z30 ; Set maximum instantaneous speed changes (mm/min) (Jerk) G28 XY ; home XY M84 ; turn off steppers G4 S60 ; wait 1 minute for nozzle to cool M107 ; turn off the fanAs you can see cancel basically just turns off the heaters and motors with a little bit of extra detail.

sweet thanks examples are a huge help. I appreciate all your help btw, You made this project go a lot smoother, probably would have taken twice as long to finish lol.

No problem. Glad I could help.
The gcode wiki is a great resource. You should always have it open in a tab. Any time you're wondering if you can do something or how something works, searching the wiki there can be a big help.

Since everything is configured with gcode, and there is basically a gcode for everything, and anything can be configured on the fly, anything you can think of doing, you can probably do.
