After I pushed. My cnc out of form I disconnected the motors and put Some tape on the shafts. I wish I did that earlyer.
3.6 volts. You where both right!
The port I bought has A universal slot, for 3.3 and 5 volts. The slot in the computer is A long one so I expected it to be 5 volts. Nope!
By running A G-code the voltage was 4.6 volts so when I jog the motors get powered bij the parallelport and running A G-code by the USB 5 volt connection.
Do I need A other motherboard? Or is there A way to fix this and get 5 volt on the port. The powersupply of the computer is 12 and 5 volts so somewere on the motherboard iTS being redused to 3.5.
Sorry i am Overwhelmed with my bad Bavarian English.
