One axis stucks when other two moved.

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:

  1. Plug power supply
  2. Move X axis > works fine
  3. Move Y axis > works fine
  4. Move Z axis > a terrible sound + system lock
  5. Reset from LCD screen
Another scenerio
  1. Move Y axis > works fine
  2. Move Z axis > works fine
  3. Move X axis > terrible sound + system lock
  4. Reset from LCD screen
So basiclly what happens is when I try to move the 3rd axis, system gets locked. Does not matter whatever combination I try. <source src="

With Repetier Host:

  1. Plug board to computer (using Mac)
  2. Plug power supply to outlet
  3. Open Repetier host and upload Crown gcode.
    1. Baud rate is 200000 (some threads says it is too much for Mac but if I go with 115200 Repetier cannot connect to board.)
  4. Run
    1. 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:

  1. Move X > works fine
  2. Move Y > work fine
  3. Move X again > terrible sound + system lock
Videos are coming

What might be causing this? Please help.

 

My electronics:

 

What firmware are you running, did you set your drivers, what happens when you run my crown gcode?

Never mind you figured this out in another thread.
