Well. A while ago the motor typically tripped and stopped on the X2 after I forgot to lift Z in the G:code before rapid to the next cutting area.
Mach3 kept the table running and there was enough force to snap the end mill in half. Was running a 8mm 4 flute at 600mm/min with rapid of 1000mm/min at the time. I didn't catch it at the time as I'd gone in the house briefly.
Since then the finishing cuts have marked quite badly. Came out really smooth before.
I've replaced the spindle (changed to R8), bearings, front of the head (spindle holding part). Taken it completely apart, cleaned and rebuilt it, new bearings all round and new X,Y ballscrews. Tightened all the gibs and it's still pretty bad if anything it's now getting worse.
Has the solid column, belt drive upgrades, angular bearings, counterweight pulley system, flood cooling etc.
The vibrations I'm getting from it have got quite bad and it screams when doing finishing cuts which it never used to do and the programs I use I've used since day 1 unchanged. Finishing cuts are coming out pretty rough.
It all feels nice and solid when you try to rock everything about head table etc, so I'm out of ideas.
Could the motor cause these kinds of issues? could it have been that all along?
Any thoughts from you guys or is it dead?
Thanks.
Daz.
Just thought to mention. Using my direct R8 collets my runout in the spindle is as little as 0.004mm according to the dial indicator so it isn't that.
