I did the wrench exercise rather easily.
I started machining the FACE exercise (tutorial 2) and the machine started vibrating. I e-stoped it and realized that the spindle pulley had gone up the motor shaft and that the belt was skipping. I managed to put the pulley back into place, and tighten the belt. ( I am very mechanically inclined by the way) but now I cannot get the machine back online.
When I press the button on the front. It blinks every 3 second and I hear a zapping noise. The light on the power supply also blinks. My two cents is that we have a short wire somewhere in there.
obviously I can not longer connect the computer and your software to the machine.
I manually moved all axises to make sure the machine was not hitting a limit switch.
the forum does not seem to mention anything on such error. The machine is a sitting duck.
