I recently bought a 3018 pro, I am using Easel and then UGS .All the speeds and feed settings are stock , My problem is when I start the machine it sometimes stalls , judders and the spindle doesnt start properly . It seems that the spindle starting at the same time as the Z axis motor raising is too much for it . I tried reducing the acceleration of the Z axis motor but same. All is ok with the spindle disconected . I changed $1 to 50ms but it judders during the job occationally. I have it set to $1=255 now it works ok but motors are getting hot at idle. Is there a way of setting a start delay between spindle and Z axis? any ideas please ?
