Breakout boards as pictured in Mach 3 guide
« on: March 07, 2007, 02:45:49 PM »
I'm new to this type of project and need to get some more clarification before I move forward.

I am moving closer to building/modifying one of our old Apple based CNC mills. I want to drive it using the Mach 3 software. In the users guide it says I should use a good  breakout board. It pictures 3 but does not list any manufacturer. I am runnning 3 slo-syn syncronous stepper motors. 1. Do I need a parallel port for each motor or are different pins assigned to different motors?  2. Where do I find the proper breakout board for my motors?

Thanks for any help provided

Any breakout will do, I have used PMDX122 and it is a nice board and reasonably priced. Also have a CNC Building blocks one in the lathe I am presently retrofitting, its a bit dearer but has some very nice functions but they may not be of use to you.
 As for parallel ports you only need 1 for up to 4 axis but can add another if you require more inputs/outputs for other functions.

Also, click on the links tab above, look in electronics. Lots of suppliers there.

only possible to have two parallel ports, if you only have one at the moment you just need to get yourself a PCI parallel port. If you already have two then there are other ways to get more I/O, one route is a PLC over Modbus.
