Hello,
I have a chinese 3020 machine and when i got it, it worked perfectly. Since few weeks i got some major problems with it and it gets worse with time.

First problem:
When i jog with my keyboard the Y axis (only in the bottom section of the working area) hangs/locks itself and it makes a strange sound. The X axis strated to do the same but only when a milling session is currently going on.
When i got the machine this problem wasnt present.

Second problem:
The spindle doesnt turn on when i activate it. It gets electricity and it makes a sound but it doesnt turn by itself.
I have to turn the spindle head by hand, in order to get it to rotate. After that i can normaly regulate it with the VFD.

I will include a Video aswell there i have recorded the problems.
Can anybody give me advice what to do?

Thank you!

Sounds like there might be some sort of bearing issue, ticking noise. It might keep going if max speed is set to lover, slow speed more torque, but eventually something will break. I don´t have this type control box, but it feels like there is not enough voltage?
