Pro2 Plus - GCode not printing as expected

[SignCov]

Hi,

I want to run a custom generated GCode on my Pro2 Plus to calibrate my retraction settings. Now my problem is that the GCode looks fine if previewed in IdeaMaker, but does not print correctly. It should look like in picture 20230228_ideamaker_1.PNG.

How it should look.

But the printer behaves like in 20230228_random_gcode_viewer.PNG shown. The encircled movement paths should not be there.

How the printer behaves. View from the top.

I use nozzle 2 (right) for this print. The problem starts at Layer 3. Here the printer wont use the relative positioning, even if it is set in the code. I tried it with nozzle 1 (left) and the print will work. So it seems the problem is specific to the second print head?

Here is line 335-341:

Code: Select all

M83
G91
M106 S255
M104 T1 S220.00
;Layer 3
G1 F4800 X-2 E0.02467
G1 F4800 Y-2 E0.02467

While debugging I removed the E part of the G1 move. Then the printhead will execute the movement correctly. Without any extrusion of course.

Code: Select all

M83
G91
M106 S255
M104 T1 S220.00
;Layer 3
G1 F4800 X-2
G1 F4800 Y-2

Does someone have an idea why the printe behaves like that? I use the newst Firmware and IdeaMaker Version. I attatched my GCode. I would be grateful if someone can verify my problem.
