Hi guys. Im a newbie to all these. I got myself a chinese CNC 3040Z-DQ machine. Assembled the machine and everything works fine. Learned how to draw 3D objects and creating tool paths. When I tried the first engraving, 1 of the gcode was wrong and lead to the spindle plunge all the way down. Jammed then stopped. I stopped the Mach3 right away. Removed the drill bit from the wood and the spindle wont run again. X Y Z still works controlled by my laptop. Just the spindle doesnt workor spins anymore. Checked the cables connects to the spindle with a DC voltage of only 0.4 Vdc. The controller machine is on and connected to mach3. I disassembled the spindle and everything seemed fine in the inside. Anyone can shed me some lights whether its the spindle or the controller having problem? Or where should I check inorder to know what should I get for replacement or get it repaired?

Thanks in advance!

if your control box is like the one in this post :-

you will see from the circuit diagram in the post there is two fuses
one for the stepper driver DC supply & one for the speed control

if your very lucky you may of blown fuse F2 that powers the spindle motor
check resistors R 3 & R4 have not been burnt by the overload

Thanks John! Will open up the controller and have a look later. Fingers crossed.
