Is there an easy way to reverse the motor direction using the software?

Thanks,

General Mach Discussion / using brains to turn a switch on

« on: December 10, 2011, 06:01:51 PM »

I am going to use a brain to activate a switch. How do I specify an output switch call in the program? Please show me a sample of code that calls for an output switch that I will then link to a brain?

Thanks,

General Mach Discussion / Getting motors to reverse rotation

« on: December 03, 2011, 06:03:16 PM »

Is there a simple way to set Mach3 to turn the motors the opposite direction that they normally do? It seems that different computers send the motors in opposite directions and I either have to:

a) re-write my existing files
b) re-wire the motor outputs

It'd be great to do this in the software. Anyone know of a method?

General Mach Discussion / x axis not moving when using one computer, does when using another

« on: November 29, 2011, 08:46:11 PM »

I am trying to use a different computer to run my machine. It works perfectly on one computer, but when I switch to the new computer the x axis  doesn't work. The pin-outs are the same. I even tried using a different set of pins and it still would not move.  Everything is identical and the y,z and A axis work fine.

My question is: Can anyone think of a setting or anything else that might be keeping the x axis from working?

I'm hoping that the problem is not the computer, but I'd like to be sure it is not something else before I take the computer back to the place I bought it from.

thanks,

General Mach Discussion / Drivers spiking like crazy -pulse rating too fast

« on: November 28, 2011, 11:12:03 PM »

OK, I tried the special drivers and it still seems my pulse is too fast. Art mentioned some sort of remedy for this. Anyone willing to help? 

My motors are jumpy and some don't move at all. When I plug into a different computer everything works fine. Ports and pins are identical. Any ideas on what's wrong?

G-Code, CAD, and CAM discussions / More questions on calling sub-routines

« on: November 27, 2011, 09:00:15 PM »

Can someone post sample code for calling a subroutine?  I would also want to quantify the number of times it repeats.  Is it just a matter of typing m98 and then following it with my subroutine, and then adding L ##  for the number of times it repeats, and then ending it with M99?

Thanks,

General Mach Discussion / Using M7 without interrupting G01

« on: November 15, 2011, 06:52:39 PM »

I would like to use the M7 and M9 commands without pausing or stopping the g01 travel. What is the correct code order to achieve this?

Thanks,

General Mach Discussion / Is it possible to run Mach3 from a USB port?

« on: October 02, 2011, 10:52:40 PM »

Is it possible to run mach3 from a USB port? It's getting harder to find computers with DB25 connectors.
Thanks,

General Mach Discussion / need to close a circuit with g-code

« on: September 01, 2011, 10:51:22 PM »

I would like to repeatedly close a circuit  using g-code. What is the best way to accomplish this? I want to activate a pneumatic cylinder during the program.

Thanks,
