I had not printed dual extruder for a while and the software has updated since last dual print. All my dual prints before worked very well. I use the wizard for the setup and everything looks great on preview but the printer beeps and stops after maybe 20% or so of prints. I have leveled the bed and made sure both noozels are equally spaced from bed. I have tried many different filaments (abs) with same results. The prints that stop are also poorly printed. I have printed the same piece with a single extruder and it prints perfectly.
I have tried using the last version S3D which I still have on my computer but same results as with newest version.
