I bought a new CoPrint for the Ender-3 V2 and have run into a bit of a problem. Several prints worked (although the retraction for the color kept screwing up), but then I downloaded the new cfg CoPrint told me to and now I have a “Move exceeds maximum extrusion” error using Orcaslicer.
I have researched the problem and troubleshot for quite a bit. I have adjusted relative vs absolute extrusion, I have adjusted both “max_extrude_only_distance: 300.0” and “max_extrude_cross_section:10”, and dropped M82 and M83s everywhere and still cannot get this error message to quit. I think it was doing okay with the first prints because I started with a reduced bed size (less then 200), just to test the color changes and when I put the correct bed size in with the new cfg, its all jacked up. I converted the “start_print” macro to a Gcode and tried to see if the flow rate was the problem…below is the picture, shows 11, but had a flow rate of 14 and still got the error. My code and pictures are below if anyone can figure it out…I am lost and CoPrint hasn’t gotten to my message yet.
