I had some technical trouble with my automated build platform today. (Yesterday? Last night? It all blurs. :) )
I’ve fixed some problems and found others.
Right now I think there may be a slight kink in my filament spindle box. The extruder motor kept running but no plastic came out in one build job. I can successfully print using the ABP as a heated build platform – but it is only really successful with single print tasks. More than that and it screws up the raft.
I’m tempted to lightly sand the automated build platform belt to see if that helps. If not, a friend suggested using blue painter’s tape on the platform. I’ll try the tape first tomorrow.
