Yeah I'm going to move the bearings to the middle and have some spaced. Looking at having a new design for that at either the end of this week or next depending on it I can fit it in or not.
@mrehorstdmd I've had it actually laying plastic fine with the head moving at those speeds, 0.2mm layers. It's using a volcano with a 0.8mm nozzle and a 48mm high torque stepper motor on the extruder. Moving XY is fine up to 350mm/s.
