Hi guys,

To update on what I have done lately. Just received my PSU from ebay. I hooked it up in place of the 24V PSU and fired up Mach3 and the drivers. Wow! just wow! I can rapid at 200 IPM without binding issue.

I am not going to cut at this speed of course but having the extra torgue and speed is well worth the money I spent.

Just one thing though, not sure if it is faulty or what, but the built in fan isn't working. Not sure why.

Can someone tell me what the terminals stands for. I have DC1 (V+), DC2, GRD1 (COM), GRD2, GRD3, FG, L and N. I know all except FG. Looks like it could be for the internal fan. Any idea what this terminal is?

I am using Keling KL5056 drivers and Keling 495 oz.in motors.
