Thanks David. I got it running fine
Im just dealing with retraction issues right now. I have 2 mechanically identical corexy machines, both with Duets.
The older one is a dual bowden system with E3D Titans and a chimera hotend. Config is perfect. Firmware is V1.20.
I copied the config to this new machine, which is a direct drive Titan and E3D, and at first glance seemed to be fine. Mechanical tweaking got things sorted.
I obviously changed retraction and pressure advance values from from 6.5mm and PA of 0.2, but i am getting corner blobs and just unexplained issues surface issues even at very low speeds ( 20 mm/sec upwards ). I have changed the hotend, the motor ( from 0.9 deg back to 1.8, and back again, different PLA ).
Frustrated beyond belief, but not beaten........yet.
