General Mach Discussion / Re: trying to set up home and soft limits

« on: October 08, 2012, 11:55:04 PM »

G70 will run your code in inch mode and G71 will run it in metric mode.  Code is simply units.  Depending on what mode your in will dictate how far the machine actually moves.  If you have a line of code that tells the machine to move 1 unit G0 x-1.0 it will move one inch if in G70 mode.   Now if you put it in G71 mode and repeat it should only move 0.0394 inches because now the 1 is considered 1 mm instead of 1 inch and 1mm = 0.0394 inches.  If your running the default mach mill screen you can also go to the settings page and click on the units button.  This will change modes from mms to inches or vise versa.  Clicking this button is the same as entering G70 or G71 from MDI.

I dont think the backlash will be causing you any trouble but you could disable it and test to find out.

Sounds like you might be skipping steps.  Has anything gotten worn or dirty that would make the axis bind?  Dull tooling, or maybe just trying to be more agressive than the machine can handle?  You could try to make lighter passes and/or detune the motor a little and see if that helps but I would check the mechanical bits first.

You can set the units to inch or metric but you will need to do the math and adjust your motor tuning.  You could also clone your old profile and name it inch or something and play with it.  Also you can use G70 for inches and G71 for MM in your Gcode.

FAQs / Re: hooking up an older spindle relay to mach 3

« on: October 08, 2012, 05:39:23 PM »

Alonzo, I think you would get a lot more input if this was posted in the general discussion board.  I'm guessing the spindle is being driven by a VFD.  If so, what kind of vfd is it?
