Hi

Some months ago me and my father bought a used X3 conversion 3axis cnc machine. It was working ok for a while and we were basically learning from 0.
Now we have run into several problems and none of us are very familiar with cnc machine electronics.

The mill runs from an Ubuntu machine with EMC2. THis is how the mill looks.
(Slightly disassembled) Sorry for the crappy phonepics. Will take better ones if required.



The first problem we had was that the display on the front that shows spindle rpm, got stuck at 0080. Everything else worked ok.
Next problem was when the Z axis went into some sort of "half speed" mode. The software on the computer displayed a much faster movement than the z axis actually travelled.
(This could suddenly bo ok if the mill was turned on for a while, got warm and then restarted)
Most recent in the line of problems is that when the mill is turned on, EMC2 gets an emergency stop signal, and the mill can not be run at all. Ontop of that, the front display is now completely dead.
The green light on the front indicates tension to the mill, and we can hear a main relay or similar connecting and disconnecting when turning on/off.
The motordrivers have 3 leds and all are showing the red led lit.

Advice on where to start this mess is appreciated. I know basic electrics but I have no idea of the electronics in the mill. I got a multimeter for measurements.

Thanks for reading.

Everytime someone uses a mill in a drill chuck, god kills a puppy. :nono:

I tend to use the drillchuck for the smaller mills.
Got approperiate equipment for all sizes that I only use for the larger ones.
Any downsides with this? Drill chuck + small radial loads = no problem is my idea.
