I've had my Felix Printer 2.0 for a couple of months now and I love it. These past couple days however I have gotten stuck trying to print support using the 2nd extruder.
I use the registered version of kisslicer and select "Ultra" support. I double checked the calibration of the bed and the hotends of both extruders. I also just did a print with a raft using the 2nd extruder and it worked fine.
In this current print, the nozzle (tip) of the hotends hits the print when it comes back from the home position to print the support. I believe the problem is that it prints three regular layers with hotend 1 (which in normal quality is 0.6mm), so when it adjusts the print head for the support layer the tip of the hotends are probably 0.2mm-0.4mm above the print bed (or the last support layer). This of course is lower than the last regular printed layer and the nozzles will "scratch" over that last layer, which damages the print and probably won't be great for the extruders in the long run.
During the last print I tried increasing the z-distance a little bit, but while the hot ends were still hitting the print, the layers wouldn't stick anymore (which I did expect unfortunately).
I think the solution would simply be to print one regular layer and one support layer right after another, rather than multiple layers with each extruder before switching. Needless to say this will increase the print time as the head will move to the home position much more frequently, but it should work.
My problem is that I couldn't find any setting in kisslicer that would achieve what I am thinking.
Has anybody here dealt with the same problem? Any suggestions for Kisslicer settings that will work for dual-extrusion support would be much appreciated. Or is there another software that supports dual extruders at this time?
Thanks so much,
Hans
