Mach4 General Discussion / Re: HOME with absolute encoders
« on: July 16, 2020, 05:47:17 PM »
That still is probably not going to work without some help from the motion controller.  The motion controller will have to define the 0 machine coordinate keep track of the offset.  Mach does none of that.  Mach's positions are whatever the motion controller tells Mach.

This is really cool stuff.  Nice job!

It would be motion controller dependent.  What motion controller are your going to use?  Some motion controller home ABS encoders just like they would INC encoders.  Others let you define the home position in the plugin configuration and when you home, it just goes to that position.

Update your video driver?

Mach4 General Discussion / Re: Mach4 feature vs Mach3
« on: July 16, 2020, 01:17:00 PM »
Stuart,

This covid crap has most of us working from home and therefore the testing that goes on before a GA release just hasn't been possible.  But 4517 seems to be doing well.  There are a few new features that are not finished in it (Timer control, multi-touch support, etc...).  But it is stable otherwise.  Try it out.

But as to when will there be a new release, I just can't say.  When will there again be normalcy?  No one knows at this point.  :(

Mach4 General Discussion / Re: Mach4 soft limits reverse axes
« on: July 02, 2020, 10:46:57 PM »
This is because the soft limits are set incorrectly.  Min isn't always 0 and max isn't always positive.  It depends entirely on how the machine was built and what motion controller is used.

The soft limits are in machine native units.  To set them, home the machine first.  Then do one axis at a time.  This always uses the right hand rule.  She the Mill G code programming manual on page 6 for what the right hand rule is. 

Run the axis towards the positive side until you hit the limit switch.  You should see the + limit light up on the diagnostic page.  Then back off a bit.  Then record this machine position for that axis.  It will go in the soft limit Max field. 

Run the axis towards the negative side until you hit the limit switch.  You should see the - limit light up on the diagnostic page.  Then back off a bit.  Then record this machine position for that axis.  It will go in the soft limit Min field.

Mach4 General Discussion / Re: mach4 gui crash

I would try updating your video driver.  My guess (because you provided no other information about your PC) is that you have an Intel GPU on the CPU with the original driver that ALWAYS fails.

I haven't got that implemented yet.  :(

Try using a Fanuc postprocessor and see if they have one of those setup for the 4th axis.  Then you may be able to adapt what they are doing for the Mach 4 post processor. 

Mach 4 is built to emulate a Fanuc 21i control, BTW.
