Toolpath not cutting as shown

[Swarfing]

Can you let us know what the parallel port address is set up as for the card? if you are adding a card and there is a port already there (not connected inside the pc) then you could be set up wrong in the software? What does XP say it is what is it setup in the setup in the software as.

Swarfing,
Don't think it's that as wrong address means it doesn't talk full stop.
I'm concerned by the statement you sometimes have to click on X first to get y to work ?

Stick a pen in the spindle and run this program.

Does it draw a square 50 mm square ?

Sorry John i totally missed the first part of the thread by a mile?

[Swarfing]

Ok read it properly now, John i agree with your concerns. Sounds more like signals are breaking down or not getting through. Back to basics do you have another PP cable to try? If Johns routine does not work. If a new cable does not work the bob voltages needs checking. DON'T UNPLUG any of the cables whilst machine is running though.

Ahh! he mentions a new cable.

Ok reading the rest of the threads it really does seem like it is all down to ports and pins. So he has all the answers just needs to stop and listen.

Hi Swarfing,

I have tried two new cables and metered both.

Do you think I really should be testing BOB voltages on a brand new machine or just send it back?

What he means by checking BOB voltages is that the BOB is receiving the correct voltage from the parallel port, you can measure the output voltage for steps at the parallel port outlet pins, some port run on a reduced voltage which isn't enough to give a good signal.

Sometimes uninstalling a program doesn't remove it all, don't know if this is true of mach3 or not but might be worth checking. Also depends on the method you use to uninstall.

Hi Everybody,

Just had the supplier on the phone and its not my fault! Its the post processor (not 100% sure what that is other than a file) in cut 2 d and it also is the control box (Some lose wires and the problem with the sticky jog keys) by all the tests done.

I have cut a square on three sides the fourth side not cutting however the display is counting down to 0 but no movement.

Will keep you all informed and thank you
