Does anyone use this ? "GM215 Step Motor / Motion Controller"

Gecko 203v Microsteppers
 

Just got the 4 drivers in. Hmmmm. I was expecting them to be bigger.

Don't let the size fool you....very powerful and efficient

They are so small because missing heatsink.

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?

PDMX-134 Motherboard
 

Like plug n play available for $65 from cncrouterparts.com

Only $55 from the website . Here is link to the boards. http://www.pmdx.com/PMDX-134

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.

This motherboard seems to be nice option.

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.

Alabama can have this back
 

I don't want it.

Well we sure had it also!! Not normal for sure and especially this time of year!!

I know what you mean. We got 11 inches here. I am 3 hrs. NE of you . Just now getting dried out before the rain hits.

Geckos and PXDM
 

Okay surprised at the might of these little drivers. Read for about an hour on them today.

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.

Okay ordered the PMDX-134 Motherboard today 55 plus 9 shipping. gets me a little closer.

Pmdx-134
 

Those people ship fast. 2 days.

I have completed a lot of hours, reading this forum. Going to take a break now.
Hope all of you have, "A Great Christmas", and a Safe New Year.

you do the same

New friend BOB
 

Okay another new year and another piece of the puzzle arrived, today.
PMDX-126C BOB. $183 with shipping. Now what size ribbon connector is correct?

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:

and for PC Connect this one or a Smooth Stepper board:

That is the combination. Thank you for the reply.

A few more parts in
 

I know I am a little slow. But things are still coming in. 2 E-switches and cables from PMDX

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.

Never mind I got it sorted.

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?

First Movements Achieved
 

First movements in all the right directions today. I quit being mean now..:D.
