Latest update. I finished up the mechanicals and created a new profile in MACH3 this past weekend and all is good. Homing and limits working too. Relieved.

Thanks HOOD for your help!

Additional vid clips of the build progress here. (Testing was done in MACH2) :

Just reporting in.  I have been working on the mechanicals of the table and have put the MACH config problem on the back burner for now.
I will be back on configuring MACH3 shortly.
It looks like this so far:

What it looks like, jogging in MACH2 environment.

Thanks.

It's 8pm here now so it will probably go to tomorrow eve here too.

The shop is about 100' from the house, it's -8 deg C with about 60cm of snow on the ground, going to take the evening off.   ;)

OK.  Thanks.  I'm sure it's something dumb that I have overlooked, something obvious...I hope.

THX!

Thanks Hood.

Attached are the two XML's I have been using.

The one in MACH2 that does exactly what i want it to do in MACH2.   'A' axis is slaved to 'X" axis and jogs with the proper keyboard keys, as do the 'Y' and 'Z' axis.

The MACH3 XML in MACH3 on the other hand, does not.  With the same pin designations as in the above MACH2 XML I get this result:

-    'Y' axis jogs with the correct arrow up/arrow down keyboard keys,
-     the 'A' axis motor now jogs with the PgUp/PgDn keyboard keys
-     the 'X' and 'Z' axis motors run together on the 'X' axis jog  keyboard keys

nothing hardware wise has changed between the MACH2 and MACH3 benchtests.

It's as though MACH3 is ignoring the pin designations I have given it.

thanks again for your time.

Yes.  Same hardware.  Kind of weird I know.  Different xml's though.

In MACH2 I use the Bridgeport's xml modified to include slaving of the A axis to the x axis. Works fine.

In MACH3 it's a scratch built xml.

Can I cross open xml's between M2 and M3? try each xml in the other MACH?

I looked at the jog hotkey designations and they looked ok except for the slaved A axis, does it matter?

thanks!

Gentlemen,

I have been using Mach 2 with Geckos on a Bridgeport Series 1 machine for about two years now with nary a hiccup. Excellent results. Very happy.

I am now in the process of building a 4 motor (three axis, A slaved to X) plasma table and I am hoping to use the same controller to run these motors with MACH3 and a torch height controller.  MACH3 is ver. 3.043.022.   BOB is a CNC4PC C11G, it is running on 55 VDC through Gecko 203V's.

Of course, I am building a new machine configuration in MACH3  to run the plasma table.  I am only in the process of bench testing the motors with this same controller used for the Bridgeport and I am having a heck of a time getting the plasma table motors to run on the assigned pins/keyboard jog buttons.

I have been methodically cross checking my ports and pins assignements as I go, comparing them with my MACH2 plasma test configuration but even with identical pins assignment in Mach 2 and Mach 3, different motors run on jog tests. All of them run mind you, the correct ones run in MACH2, but not in MACH3.

I have been careful to save the setup, shut down the controller and Mach3 between config changes and jog tests but I am obviously doing something wrong. I'm kind of at wit's end at this point.

I have attached some screenshots.    Can anybody perhaps suggest some things I should check?  Thanks in advance.

Hi all, Mark here in Montreal Canada

I did a Rong fu mill drill 3 axis servo & ball screw conversion with Jeff Davis' help three years ago. ( http://www.homecnc.info/cnc-main.html )

Having lots of fun learning how to program and make parts.

My current project is adapting a GM performance parts 2.4 l Quad 4 supercharger kit onto a 2.3 l Quad 4 motor for a Fiero.  A bit on how Mach was used to make one of the main components for the project here:

cheers!
