Heat sink? Good idea--Thank you. I think placing these on a motherboard will be a good idea. Is that what most people do now?

Read gecko manual. Heatsink is nessecary, and of course heatsink compound between driver and heatsink. What did you mean by motherboard?

Example setup
Example panel using the PDMX-134
This photo on the left came from this thread - http://www.cnczone.com/forums/gecko-...mdx-134-a.html The photo is not correct - The Geckos are installed backwards on the PMDX-134 board! The correct configuration is on the right.

You are getting to the fun part of the project.
I finally had to do a repair on mine. almost 2 years. The transformer/power supply is causing uneven power through the contactor. 144 volts one side 106 through the other. It was a head scratcher till we figured it out.

Infinite apologies for being sort of Dyslexic. I have been typing PDMX.
It is PMDX.com So I believe I am going to use the PMDX-126 Rev-C breakout board. The PMDX-134 Motherboard and mount them all on an aluminum screen for a heat sink with a fan to pull the air through. I see Metalhead's setup uses the PMDX-126 at one time as well.

I had a problem with mine with a bearing sticking in the z. It was causing voltage problems. Everyone kept wanting me to replace the power supply. Replaced the bearing and all is well. Keeping it greased correctly from now on.

I suggest you reach back out to PMDX and let them know you have the PMDX 134 board. He will tell you the correct cable, but I suspect it is this one:
http://www.pmdx.com/HDR26Ribbon-18 and for PC Connect this one or a Smooth Stepper board: http://www.pmdx.com/DB25MtoM http://www.pmdx.com/1PARPCI

Is it acceptable to just reverse the wiring, on the 8 wire stepper motor. So one runs in reverse on the x-axis, or do it through mach3. I have been reading and am just a little confused.

Okay all I did was reverse the wires at the drive. That is what it looks like most are doing.
Is that right? Also is there a basic xml file already for Mach 3.

Can someone point me to the post that determines ports and pins setup for mach3?
In other words how do you determine the ports and pin setup in mach3?
