Hi not long had my ctc brought is as my clone makerbot board stopped working


so brought a ctc basically the same upgraded the feeder and replaced the throats to ones that don't use ptfe tubes. (Same setup I was running before)


but now have the problem when it seems to jam when it starts the infill. (same file iv been using time and time again with no problem) I am using sailfish 7.7 abs temp is 240-250 and bed temp is 110c . when it blocks if I pill the filament out and reload it no problems will reload and print again until infill.


I have tried the olive oil trick on the tip of the filament when loading and this makes it print ok??? (not even sure its safe to do with abs I read its more for pla) I don't want to relies on oiling it all the time though? what could be the problem?


many thanks any help will be grateful!!
