I have also connected another motor and let it run freely and there the same problem occurs.

Edit: I also tried printing the top layers to check if it has something to do with the z-height, but there the problem does not occur.

Hello all,

Recently I have a strange problem that I have not been able to solve. I have a Renkforce RF2000, which is equipped with two extruders. The extruder in question is attached to the side of the printer and does not move when printing. I want to print fiber-reinforced samples, so I generate the Gcode myself in a program I wrote, which has always worked well so far.
Currently I want to print tensile specimens with fiber reinforcement.
In my problem, I am printing three samples side by side. From a certain layer, where fiber strands are inserted, fiber strands are surrounded by normal plastic. The printer does the same for the first sample and then switches to the second and from that point on the extruder stops spinning. The extruder also can no longer be controlled to pull back or extrude filament. Only when I restart the printer it works again, but breaks off at the same point during printing.

The previous 20 layers everything works fine. The wiring also looks good. I am using firmware 2.0.5.

Does anyone know how I fix the problem?

Thanks in advance!

@Phaedrux
Thank you!

I printed a similar sample today and I had no problems with these. It must have something to do with the layer geometry. I still can't explain the error.

I have attached my config.

Attached is exactly the layer. The left outlines are printed. Then the print head moves to the right side to print these outlines as well and from this point on the extruder motor can no longer be controlled.

@sn0w1995 said in Changing the extrusion letter for the second extruder:

Hello,

I am relatively new to working with Duet3D and have a question:
My slicing program generates two different letters for the extrusion for the dual extruder, for example:

Extruder 1: G1 X1 Y1 E2 F1000

Extruder 2: G1 X1 Y1 U2 F1000

Unfortunately, the printer only works with the E letter for extrusion. Is there a way how I can also use e.g. the U as extrusion letter in the firmware for the second printer?

Thanks in advance for your help!

Nope. "U" is used as an additional axis. What slicer are you using that generates extruder moves as non"E" values?
Thanks for the quick reply.
I use Aura2 from Anisoprint.
Would it be possible to use, for example, A or B or another letter for the second extruder instead of the "U"? Then I could just replace the U manually in the generated G-code?
