So My TC is running great. All 4 extruders print well. Toolchanging is now as close to 100% reliable as I can get. So now I am trying to print a simple multi-color PLA 3D Benchy and DOH! The hotends have so much drippage they eventually knock the Prime Pillar (S3D) right off the bed. I tried 4 times. Next I'll try with an Oooze Shield instead... But... How about wiper designs? The idea of replacing all the nozzles with steel replacements only because of the use of a wired brush can't be the only way to do this. I have a batch of the thick felt strips that Aleph Objects uses in the lulzbot mini for nozzle wipes and I will see if I can insert a piece of it into the wiper part that is on the Github. It should be fine with brass hotends. But there must be other approaches. While at MRRF I saw the 3 beta E3D TCs. One had a kind of bladed thing in front of each tool such that when the hotend passed over it the blade knocked off any oozing. There's nothing like that I could find on the Tverse. I think it was on Hackney's machine Then there's how you get the wipe to happen??? I see the "Brush.g file... Do I insert gcode in a tool change script (S3D again)???
