General Mach Discussion / Re: Mach3 win7 32bit, movement only in one direction, what to do?

« on: February 12, 2018, 04:04:30 PM »

Now I am really lost. 5 volt max voltage on the dir pin. When jogging or not. Also on the com pin and About 0.4 on the step pin.
I can't figure out what settings I could alter. At this point it's only the ports and pins settings to get my motors running. What am I doing wrong?
By the way: i'm an building/construction engineer and not an elektronic engineer so forgive me if I don't get it.
About two years ago I finished my home build cnc. The software and elektronics took me A lot of YouTube tutorials viewing but I got it working. I'm supprised that it doesn't work anymore.

Thanx for the help til so far.

I did use this post to identify if I had A 5 volt slot and to buy A pci card. It didn't work so far. Tried it with xp and with two other older desktops.
The problem remains the same. I was thinking that maybe The driver for the pci isn't the right one. The pci I bought is A delock.

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.

Hello everybody, my xp desktop crashed. Now i've got A Windows 7, 32 bit version and i'm trying to get my cnc router working again.
I have movement but only in one direction. On this forum I read A topic with the same problem, solution was the difference between the old and new parallel port, 5 and 3.3 volts. I changed mine for A 5 volt version today but the problem remains the same.does anybody have ideas how I can fix this?
