First, I have a DM4400. It has the Servo Dynamics SD303 amp and the SEM DC Brush spindle motor. I have both running fine under Flashcut CNC and a small board I made.
I'm pondering replacing both with the Mitsubishi motor and drive similar to the later model DM4400M which had the Mitsubishi Meldas M3 control.
What I am hoping for is someone with a DM440M that can take a picture of:
The spindle motor label
The spindle motor drive label
If feasible the mount on the head of the DM4400 that the motor bolts to.
Post here for others if possible.
Thanks in advance.
