I've managed to dual-extrude with 2 different PLAs with different temperature profiles to print successfully. I've been able to print out any number of things w/ PolySupport by itself. When dual-extruding with PolySupport, it doesn't seem to matter which extruder I use, but the PLA side inevitably jams up and starts clicking, sometimes before it even does its first layer.
I've tried all sorts of temperature profiles, different brands(Hatchbox,Zentoolworks,AIO), different tensions on my Bondtech.
If I use Polysupport for my brim or raft as well as support, that prints out fine, but the PLA side usually doesn't even start when the printer goes to do the extruder switch.
If I use PLA as my primary material, I will get one layer, then the switch to PolySupport, then clicking and nothing for the switch back.
I've read through the message threads here, I'm using the Raise3D PolySupport profile, I've scoured the web elsewhere. I'm stumped.
Any further thoughts, tips, profiles, etc. would be appreciated.
Being able to do this sort of work is one of the main reasons I went with a dual extruder printer like this.
You're saying that non-Polysupport extruder clicks when printed with polysupport on the other extruder?
But this never happens when you dual extrude with both regular PLA filament?
If so, that's weird behavior. Only explanation I can come up with is that the polysupport is overextruding, resulting in thicker layer height. So when the main extruder tries to print on top, the gap is very thin due to the thickened layer from Polysupport. This restricts the amount of filament that's trying to come out of the nozzle, causing a backup, therefore building pressure inside the nozzle, and finally the extruder gear can't push it, with the inevitable clicking. Hope that makes sense.
I tried PolyMaker PLA and polysupport dual extrude to print a Hilbert cube successfully without much trouble.https://www.thingiverse.com/thing:16343
Try lowering the flowrate on both extruders as much as you can, and raise the temp.
edit: also try thicker layer height, like 0.2mm
edit2: if your main extruder starts clicking before laying down ANY filament (that is after switching from the polysupport extruder), then all of the above is moot.
