Solved IDEX Duplication issues U prints, X Doesnt
-
Hello,
I have a custom IDEX machine that's been working great for a month or so now, and I finally calibrated the 2 hot ends so I can print duplicate objects with each extruder. I went through the guide on the Duet page for configuring multiple independent extruders, and have the config setup so that Tool 2 is the duplication setup.
I am using Simplify3D and I chopped the X width of the build area in half so that S3D works in the "box" each extruder has access to.
I've set it up so that the printing happens with "Tool 2" "Extruder 1" in S3D, and the heaters are for T2. That all seems to work kosher. When I start printing, the U Axis moves, and starts printing as expected in its half of the build area. The X axis side just stays parked off to the side, extruding filament as if it was printing but nothing is being sent to it for movements.
Below is the Config.g (Everything under the network section in my file) Any help would be appreciated:

I would find it easier to understand your configuration if you centred the print area at X=0 Y=0 (which would also support mirror mode). But from your M208 commands, I guess that for single-extruder printing you have centred it on X=150 Y=150.
I don't know how you have centred your print in the slicer when you are slicing for duplication mode (if you were centering on X=0 Y=0 for single extrusion mode then it wouldn't change), so I don't know exactly what is going wrong. But I can see that you have defined your X and U tool heads to be 300mm apart, because you have given them offsets of 150mm and -150mm in the G10 P2 command. This is wrong, if the bed is 300mm wide then they should be 150mm apart. So try changing the offsets to 75mm and -75mm.

Yep, that was the issue DC42, I started to figure that was the problem when I was thinking of the alignment I have on this printer - Justified to the left side so I had to set the offset to 0 on the X Axis hot end. Now it prints great!
Thanks,
Joe
