Troubleshooting non responsive machine- Mach3/Syil x4

Nothing happens on the diagnostics screen when press left or right

Okay, that surprised me.

Can you measure the pin 17 voltage on the parallel port, with respect to gnd (any pin 18 through 25). Again, this is computer-side only.

From the RUN page, slew the X axis left and right (verify with DRO). In one direction you'll get 5V on pin 17, in the other, 0V.

Okay, so the pendulum of blame swings from BOB to PC.

Now that I know that you're happy patching pins on the parallel port, lets test the actual machine.

With all cables/ribbons on the Syil in place, from the DB25 on the machine (not the PC!), ground the X-Axis "Step" pin (pin 7 to pin 25). I'm assuming here that the pin is pulled high on the BOB. At the point that you ground the pin 7 you should get a single step on the x-axis. Continually breaking/making that connection should introduce further steps. The machine isn't going to launch itself - just move microscopically in one direction on the X-axis.

If that's the case then I think you need to look at the parallel port set-up.

I thought it mite of been the pc so I got a new one - the pc is new and the problem remains.

I mite wait till tomorrow for that one - most of my gear is on my houseboat. I’m just rummaging around the shed floor atm so mite wait and go get some proper jumper wires and what not from the boat and do it semi properly tomorrow

You said in your first post that
you have:
-replaced the pc (was on it way out anyway)
-checked the ports configured

Did you actually checked that the Port Address of your new pc parallel port matches the one you set in Mach3 (0x378)?

Don't know if this as been asked but did you install Mach3 and the parallel port driver or just copy across your old Mach3 folder.?

What OS does the new PC run?

Anything newer than Win7, (aka 8.x or 10), and anything 64bit, won't work with the parallel port.

Is that correct or should it be the ‘com1’ address?
