I still haven't gotten anywhere with this spindle problem.  I should clarify that I am just using a relay to control spindle on/off, so my understanding is that it should be set up in "output signals" rather than "motor outputs".  Does it matter which "Output #" is used?  I'm using a Bob Campbell combo breakout board but I haven't been able to find out what pin it uses for the spindle.
Also, the spindle button on the Mach3 screen blinks when pressed.  Should it do that in normal operation?   

The LED on the machine? no

I am, in fact, missing the Step Pin#, Dir Pin#, Step port, and Dir port numbers in motor outputs, but I don't know what they should be.  Are there numbers commonly used.  How else might I determine what they should be?  I'm also not sure what you mean by "Output configure to turn on the spindle".

What should I be looking for in the steps/unit in motor tuning?

#2- Whether I try to manually turn the spindle on from within the interface or through G-code, it doesn't respond.  It's set up as a simple power on/power off with no speed control.

#3- Something's up with the units or scaling also.  I set the machine to inches in configuration during set-up and I've made sure it was in inches in the setting tab.  When I set the step jog to 1.000 the machine moves about 1/4" (~7mm).  Scaling is set to +1.000 on the DRO.

Any help with these?  Thanks.

Great, that did it.  When I opened the hot keys dialog it disabled the x,y keys though, but I was easily able to put them back in.

I've done a reinstallation of Mach3 on a mill and am slowly getting everything back to an operational condition (and when I'm done I've got to save the settings so I don't have to go through this again).  Anyway, I can manually jog the x,y,z axes using the buttons on the jog tab menu and the x,z work with the keyboard arrow keys, but the z doesn't respond to the +,- keys.  In every other way, the z seems to respond find.  Any ideas?

Thanks, Glenn

That's what it looked like that code was doing, so at least I'm understanding something.  But it still seems to me that there is nothing telling the machine to go to its tool change location.  Would that be a different code?

The first sentence of you last post, "I just looked and the 1024 set has those as user defined dros. 1200, 1201 and 1202", is gibberish to me.  Is it something useful for me to understand?

I believe the DRO positions are machine coordinates, but the machine is moving neither the amount shown or to that machine position.  Think you could tell me how to open the screen in Machscreen?

Thanks for getting me to see those buttons on the screen below the menu bar.  I knew I had seen that tool change location somewhere.  I've played around with altering the tool change location, and though I've seen some differences in where the machine goes, the changes in movement are neither in the direction or on the scale of those that I make on the settings page.

Any other ideas?

Thanks for the comments guys.  Today I worked with the machine again with the same problem, but then I set a different origin location for the piece and the machine didn't run outside of its limits on the tool change.  I'm still trying to understand where the location command is coming from for the tool change.  I hope someone can look at the attached code and tell me what it's saying.

I'm sorry, but I'm still not making sense of things.  I wish I had time to learn programing but I just don't.  I manage a multi-function student shop at a small college and am using Mach3 on a bridgeport mill which a student converted to CNC some years ago (he's much brighter than I am).  From what reading I did, it seems that the M6start/end are about returning the machine to the x,y location it was at when the tool change command comes up, after having been moved in order to make the change.

When you say there isn't a default tool change location, you mean that Mach3 doesn't have one?  I thought that there is a location which can be specified for a specific machine in Mach3.  Is that what you were referring to when you wrote, "enable the tool change in general config."?  I looked in general config and couldn't find anything about tool change location (just the 3 button options), or anything at all with x,y coordinates.

What am I missing?
