Run G1 for 2 tools simultaneously?

[CJ.BRAVO]

Hey,

As I understand gcode, it has to wait for the line of command to finish.
if I run this segment:

T0
G1 X24.577 Y197.646 E0.5019 F1470
G1 X26.626 Y197.646 E2.7959

it has to finish line 1 before line 2, right?

But can I do this:

T0
G1 X24.577 Y197.646 E0.5019

T2
G1 U26.626 Y197.646 E2.7959

And have T2 line run at the same time? T2 is set to be on a different X axis (U) but both are running on the same Y axis.

Why would I do this?
I'd like to try and print parts of the same model using two tools at the same time.

Using DUET 3

Thoughts?

@CJ-BRAVO I think you’re describing an IDEX printer. You can set up a tool so it prints on both extruders at the same time.

You could also simply command the U axis in the first line

G1 X123.4 Y123.4 U143.2 F9000000000000000000000000000000 E0.00000001

@bot
yeah but lets say I'd want a different E amount...

@CJ-BRAVO

Oh, right, yeah, no.

Maybe you can specify two E moves?

G1 X10.0 Y12.0 U15.0 E0.5:0.4

@droftarts

I know IDEX but the link you mentioned is for 2 copies of the same model.

I'm thinking of a simple model that would run the same Y but different X,U and E's.

@bot

Not sure if that works in that case.
There's M567 for mixing ratio but that's per specific tool...

@CJ-BRAVO only one way to find out
