I tried this code in the Select Extruder and Deselect Extruder tabs

G90 ;absolute positioning
G28 X0 Y0 ;move X/Y to min endstops
G90 ;absolute positioning

and it caused my extruder to move out of bounds off the bed. So what's the code to do something like this and where do I put it.

Edit: My Subject should be "Moving The Dual Extruder Head While 2nd Extruder Head Is Heating"

my thought would be to add something in your select extruder gcode tab like:

;Raise Z
G1 <Z+5>
;Set Extruder temp(no wait for warm up)
M104 <TEMP>
;Start moves
G1 X0 Y0 F(your speed here)
G1 (your next move)
G1 (your next move)
G1 (final position)
;set extruder temp and wait till its there
M109<TEMP>

Hope that is helpful


Here's what I use for my CubeX running RAMPS 1.4/MARLIN
; Select new extruder
T<EXT+0>
;Raise Z to safe height
G1 <Z+10>
;Move to left side of print bed
G1 X5 F3000
;Move to back of printer
G1 Y275 F3000
;Move to right, over waste bucket
G1 X 245
; Warm it up, and wait till it's warm
M109 S<TEMP>
;Reset Extruder
G92 E0
;Purge Hot end
G1 E30 F200
;Wipe the tip
G1 Y 260 F3000
;Reset Extruder
G92 E0

Thanks, that worked for what I needed with a slight mod.

I was looking for something like this as well, but I was hoping there's a way to get the location of the center of the prime pillar?

There are the <NEXTX> and <NEXTY> tokens. If you have a prime pillar enabled those tokens should evaluate to the next starting position (which will be on the prime pillar). If there is no prime pillar or wall selected, then that next point will be on the model, which probably isn't what you want.

I tried using
but it just sent the head back to the home position. It still ended up working ok for me since I used a wall instead of a pillar. The main thing I just wanted to get the hotends out of the middle of the print.
