Hi folks,
Currently finished building the machine but struggling of running it.
I tried to have a test to move axies via LCD screen to see if everything works fine. But let’s see what happens in sequence:
- Plug power supply
- Move X axis > works fine
- Move Y axis > works fine
- Move Z axis > a terrible sound + system lock
- Reset from LCD screen
- Move Y axis > works fine
- Move Z axis > works fine
- Move X axis > terrible sound + system lock
- Reset from LCD screen

With Repetier Host:
- Plug board to computer (using Mac)
- Plug power supply to outlet
- Open Repetier host and upload Crown gcode.
- Baud rate is 200000 (some threads says it is too much for Mac but if I go with 115200 Repetier cannot connect to board.)
- Run
- Immediatly terrible sound + system lock

Some guys on FB group suggested a higher power source. But even if I unplug (let’s say) Z motor and left two motors connected, same thing happens:
- Move X > works fine
- Move Y > work fine
- Move X again > terrible sound + system lock
What might be causing this? Please help.
