IDEX Changing tool macro

Cyberyo34

Hello guys,

I actually assembling an idex printer and all goes well exept a problem for changing tools.
My printer have actually 2 tools TO and T1,

I try to make a z hop of 0.5mm when changing tool with tpost and tfree macro from example in the doc.

When i select TO, all is going well, but for T1 the Zhop and ZLIFT value is decrease from 1.93mm and i don't understand why.
When i check the Zvalue from dashboard, example 30mm when select T1, first the value is increase from 5mm and decrease immediatly from 1.92mm.

I need a litlle help please to check where is the problem.

Here is my config file :

I check if the offsets of tools was ok and don't see any problem.

Thanks for your help.

@Proschi78 hello, thank you for your help.

I just try know with your macros without the Z lIFT,

The problem is before the Z high is reset to the correct position, the tool is in position and start to work for one lyer, after this layer the tool come back in correct position.

I got the same result with my macro too.

I use superslicer, maybe the information for X height is not send at the good moment by the slicer?

Here an example of gcode :

I tried to added T0 and T-0 each time the filament change, the result is the same.

Thank you for your help

@Cyberyo34 I only print dual with simplify because the Prusa slicer doesn't have a tower to deny. But I don't think the slicer is responsible for this.

Proschi3D

Do you have something in the tool changer in the prusa slicer?

@Cyberyo34 I recently ran into a similar issue, and I fixed it by guarding the tool change macros with M400 commands at the beginning and the end of the macro files to ensure moves aren't getting interleaved.

@Proschi78 In tool changer i have nothing, only in filament gcode start and end (EX T0 and T-0)

I think the problem is the offset of Z, i 'm trying now to put a Z offset

Proschi3D

@Cyberyo34 Here is a gcode of simplify in dual mode.

Offset_X_Y_dual_extruder_1.gcode.txt

@Proschi78 Thank you so much !

It seem my problem was about the zoffset of tool 1, but only on firmware issue, i don't understand why, physicly my 2 nozzle a straight, i think this is about the probe offset maybe but the value it's not the same...

Now trying my first print in dual. ;op
