I have the Taz 4 with the dual filament head. Ever since i upgraded the head i have had issues completing a print.
I use MatterControl because i like it alot.
I was playing with the tune (flow, speed, layer thickness) and got it down really nice. I printed a part that needed support material and would switch between the 2 filaments regularly. and got all the way thru it without any issues. it was an 8 hour print.
So i thought perfect, now i’ll try my big part.
it started out perfect, then i came back the next day and bam, take a look at the picture.
it looks like the Y axis lost its step because after a few layers everything is just moved back about 25mm.
then a while later it did it again, but the X axis moved over 15mm as well.
has anyone had this happen?
