Topic: Cannot stop z-probe after print

Hello! For whatever reason, my press insists on doing the z-probing after a print is finished, and in turn mashes my finished prints

I am using rh, tried deleting start and end g code in both print settings and slic3r with just the box checked for park after print, and now I'm running it with just this in the printer settings, with park after job/kill unchecked
start
G21; set mm units
G28 X0 Y0; home x and y axes
G29; probe bed
G90; set absolute coordinates
G1 Z5 F300 ;move platform down 5mm
G1 X10 Y10 F3000 ;move to front left corner
M109 S[temperature]; wait for extruder temp to be reached
G1 Z[first_layer_height] F200 ;move platform close to nozzle
G92 E0; reset extrusion distance
G1 E7 ;extrude anchor

end
G28 X0 Y0  ; home X axis and y axis
G1 Z150 F300 ; lower platform to bottom
M104 S0 ; kill extruder temperature
M140 S0 ; kill bed temperature
M84 ; disable motors

Please help me!

Re: Cannot stop z-probe after print

Remove the G28 in your end code. This is what the printer uses to find out where things are. It does this by moving the nozzle around until it hits various limit switches.

Re: Cannot stop z-probe after print

If you want to home your XY AXIS at print end just like trayracing said remove the G28 Command. But rather than remove it, change it to G1 X0 Y0.. That will move the X and Y back to home position.

Printing since 2009 and still love it!

Re: Cannot stop z-probe after print

Ok I will try that and report back!
Why does that cause it to go through the whole bed leveling z-probe procedure?

Re: Cannot stop z-probe after print

G28 shouldn't trigger the whole 9-point leveling (That's G29), but it will trigger a z probe to home the bed (and the moves for probe extend/retract)

If you're looking to move the nozzle out of the way, use a G0 X180 Y180. (don't move it all the way to the right - that restricts cooling air due to a design flaw.) Also, ideally you'd set to absolute coordinates before that, in case some crazy g-code left you in relative mode.

Ohhh ok that makes sense! I'll give it a try tonight, and I just installed a better spool holder, so hopefully with that and fixing my end code I'll have some better luck

Re: Cannot stop z-probe after print

still probed z after my new g code

end:

G1 Z150 F300 ; lower platform to bottom
G90; set absolute coordinates
G0 X180 Y180
M104 S0 ; kill extruder temperature
M140 S0 ; kill bed temperature
M84 ; disable motors

sad

(this code is in printer settings in the scripts tab, slic3r g-code section is empty)

Re: Cannot stop z-probe after print

Sorry you're still having problems. Look at the print log to see what commands are being sent at the end of print. Maybe there's an unexpected command in there (or  some sort of message from the printer.)
