General Mach Discussion / Problems Setting Home limits, table size etc

« on: June 21, 2010, 05:56:05 PM »

HI All,

I am running through the setup of my home limits, table size for the first time and seem to need some assistance. I have viewed the online video which was some help, but still having some problems.

I have all three home switches functioning properly, inputs configured and working.

A few questions:

   Can I tell just a single axis to go "home" to test it out before tackling the other axis?

   When I manually jog the table to home and all three home switches activate, how to I tell Mach3 that this is Home.

   My DRO's seem to be reading twice the actual table movement ie" I get a DRO reading of 72 for 36" of actual table movement.

My table is 36x36 with a 5" Z axis

Any assistance would be appreciated.

Thanks

General Mach Discussion / Parallel Port Test Pulsing too fast

« on: June 10, 2010, 09:33:22 PM »

Hi All,

Having difficulty setting up a new PC on a 3 axis cnc router I have previously used.

When running the parallel port test immediately after the system preparation screen it says "Pulsing too fast" then it goes into the "system take over in..." mode and the speed says excellent.

Following this test I am still unable to get any movement out of my motors. I have been through the pin I/O successfully before on this cnc machine and am confident the configuration is correct.

The only reason for moving to a new PC was the old one crashed, it was still under warranty and received this replacement.

I do have a non integrated video card.

Would installing a dedicated parallel port possibly help?

Any suggestions would be greatly appreciated.

Thanks
