micro mill electricals problems, help please!!
matnewsholme:
What type of fuse are you fitting?. It may need an anti surge one. You can usually tell by looking at original and seeing if it's a empty glass tube or if it's filled with white powder. If the latter its anti surge.

its the glass tube, I assume its the correct one as its been fine for over a year. Instructions say its an X1 Super micro mill

Strongly suggests that the controller has failed. If the motor is spinning up, chances are that the motor is OK.
Can anybody tell me if it is an AC or DC motor and what the voltage range is? Is it on a plate on the motor casing?
drmico60:
The X1 mill is powered by a 150 Watt dc motor. This motor has a voltage rating of 180 V. It has an DC electronic controller with feedback via a current sense resistor to help maintain a constant speed characteristic with varying load.

Would this controller from ebay do the job? The output would need to be routed through a reversing switch.
