Re: Tip of the Day 8- Scripts tab, G-Code

I am printing with a T Rex 3.0 and the Single Extruder profiles, both Right and Left, have this script in the Start Script tab:
T0
M106 P0 S[fan_speed_pwm]
M106 P1 S[fan_speed_pwm]
G28 ; home all axes
M420 S1
G1 X-42 F8000
G92 E0
G1 E5 F500
G1 X0 F5000
G1 X-40
G1 X0
G1 X-40
G1 X0
G1 X-40
G1 X200
G1 Y200 F5000

It works great, wipes at start and runs the fan with my modified settings in the Cooling tab.

The Duplicate profile, which I use frequently, has only this script in the Starting Script tab:
M106 P0 S[fan_speed_pwm]
M106 P1 S[fan_speed_pwm]

I get no wipes at start on either extruder and the cooling fan does not come on on E2. I must turn it on in the Tune menu and turn it off after the print is complete.

I have read through all this topic and several others on IDEX printing, and even several gcode youtube courses but am out of my depth and just want to print well.

I have not pasted the single extruder code into the duplicate process because I am not experienced enough to understand the interaction of the Marlin IDEX Duplicate menu role and the T Rex Duplicate profile which treats the bed as two separate platforms but with extruders that need to home and wipe in opposite directions.

I am averse to head crashes after the few I’ve had and appreciate any expert help. Thanks.
