Hey All, I have a Challenge 15MP which is the knock off of the SP-15 and am having two issues that I would love some help figuring out.
Question #1: Oscillating Roller
Recent home construction resulted my contractor accidentally flooding the room where I keep my press with very fine concrete dust. I cleaned off my press till it was shiney as possible, oiled it up and started printing.
Everything was going fine till my roller locked up. The newly applied vaseline was thick as mud. I cleaned, vasoline and cleaned the worm multiple times and now it’s looking much better and thinner after running for 1/2 an hour. Still, I can hear a few bits of debris rolling around in the core of the roller.
Would love to take the roller apart and give it a more thorough cleaning. Not sure if the Challenge roller is the same as the SP-15 roller but there are no set screws or apparent ways to take the roller off of the worm. Does Anyone have any thoughts?
Question #2: Switching Itself Into Trip
About every 15th run my press switches itself from print into trip. This happens when the carriage is 2/3rds of the way back to the starting position and I can’t seem to figure out why and what to adjust.
Thanks in advance!
