General Mach Discussion / Re: 1 drive 3 axes and mach 3

There you go then... replace the motor with a big FO stepper and use the PP port - (is joke).

I'll leave you to it - but if you need any help don't be too shy to shout up  .

Ah - understood. Thanks.

Just tried it here for the hell of it with the PP and unlike your CSMIO - Mach doesn't give a monkey's - all three axis pumping steps out of the same pin.

OK - but whatever systems you're using, "somewhere" you must configure Mach with axis step and dir info so my thinking is you make them all the same. Maybe not. I'll get back in my box

Like I say - I'm out of my zone so bear with me if I'm being dumb here - but whatever type of drive you use - don't you set up "pins" somewhere?

OK - I'm out of my zone then - but just for my edification - how does Mach send out +/- 10V?

Mach itself could not send the signal to one drive when commanding different axes but it is likely you could trick it into doing so.

Why not just setup each axis step/dir pair to be the same two pins? As long as you never command a 2 or 3 axis move (particularly of different directions) you should be ok. So as you say - just have an M call prior to each axis move to select the appropriate clutch - then whether you command XY or Z it will activate the same two pins?

The file you posted in reply #21 is not an XML file. It's a copy of the program MachXML.exe. Please post your xml PROFILE file. That's the one ending in .xml in your Mach3 folder with the same name as the profile you're using.

Click on menu item "operator/edit button script" then click on the (flashing) Ref All Home button. You'll see the macro code for that button. To understand the numbers in the doButton calls see http://www.machsupport.com/forum/index.php/topic,6657.0.html Then read the above pdf with regard to the refcombination procedure call. All will become clear.

Can you post the gcode from the two wizards?

On/Off control of your router could be simply implemented with a suitable relay setup. A solid-state relay is (IMHO) the easiest way.

Current control is perhaps more of a challenge - I'm sure there are folks here who can advise you better but PWM control is a possible option for your setup.

To home simultaneously (where you use separate pins for each axis) you need to edit the "Ref All Home" button. Currently you'll have something like three separate DoButton() calls. Have a look at the "RefCombination" procedure call in the Mach3_V3.x_Macro_Prog_Ref.pdf at http://www.machsupport.com/help-learning/product-manuals

your "glitch" sounds like you have noise issues or dirty/bad switch(es).

Sorry but you've slightly lost me on your circle wizard issues.

Spindle control very much depends on what sort of router you have - i.e. more detail needed.

Hi again LGF. Good to see you're making good progress.

A note about your limits - I think I mentioned it before but you don't need a brain. Simply tie all your (NC - normally closed) switches in series and stick em into ONE input pin. Then when ANY axis hits a limit it'll stop - Mach doesn't care WHICH switch was hit - the result is the same - STOP. Homing will also work with all switches tied to just ONE pin. The only "down side" as opposed to using three pins is that each axis will home one at a time rather than concurrently.

Re: your circle wizard - do you mean the CODE was a square with rounded corners (unlikely) or that the actual cut looked like a square with rounded corners? If the latter then that definitely sounds like backlash.
