Can you describe what you want to happen? I have a feeling that the AI might be over-complicatiing things. But without knowing your requirements it is hard to tell.

Does the MPG connect to a Mesa counter, or only to GPIO?

Remapping is way way over my head and messing around with it can crash my machine
 

The simplest case of remapping is fairly straightforward. It starts off looking a lot like a subroutine in its own file (which is also a possibility) 

See section 2.6 here: linuxcnc.org/docs/stable/html/remap/rema...xample_remapped_code

Your ngc file would probably just contain the usual G83 but wrapped with a spindle reversal, and passing-through the XYZRQ etc parameters. 
 

What happens if you just wire selected-pocket directly in HAL?

Unfortunately a problem has been found with the 2.9.5 release with the touch-off dialog in Axis. 
It will not accept values other than zero. 
If you don't use Axis or always touch-off to zero then you can use 2.9.5 without problems. 
If you do need to use Axis and non-zero touch-off then you can either revert temporarily to 2.9.4 or MDI G10 to achieve the same effect as the touch-off dialog (which actually does use G10) 

I hope to release a 2.9.6 with this problem fixed rather more quickly than the usual "measured" cadence. 

Now believed to be fixed: forum.linuxcnc.org/29-forum-announcement...xcnc-v2-9-6-released
 

Basically what the original m10 from probe basic does. It tells the carousel comp the pocket number

What does M120 do?

So you are saying that you commented out the HOME_SEQUENCE  lines
in the ini file and then got:

1. Individual axis check boxes for homing in the GUI (Axis)
2. When you selected an axis and pressed the Home Axis
button, the selected axis did not move?

Other questions:

What version of LinuxCNC are you running?

(not that this is likely an issue with an official release since there are probably more than 100000 LinuxCNC installations
using home switches)

So the real question is what is different about your configuration?
 

I think it may have been a typo, but even then, there is a far better way to have multi versions of Linuxcnc, that's the beauty of building from source, if you can follow instructions you can do it, and taking advantage of the run in place facility, aka RIP.

I used both several years back, the free version of QCAD was perfectly fine for what i needed back then.

You may try 2.9.4 if you like.

Your HDD probably has enough space to dual boot LinuxCNC 2.9.4 and 2.9.4.

Why? What's the point of having two of the same version?

Are you still using the above attached config files? They are missing home switch inputs in hal, and Mesa inputs are in the wrong place.
Make a new config, this is to messed up.

I'm still using the BT40 spindle that this machine came with. However getting the preload right for the spindle and getting the upper bearings for the quill drive to like high rpm milling for prolonged periods has been a challenge. I've been planning to replace the spindle for quite some time but not really taken leap yet.

However after fiddling with the spindle for sometime I've realized that I have to set the preload when the spindle is really warm in order to get a preload that works.

This in turn requires me to do few minutes of spindle warmup at lower rpm when the spindle is cold before I can crank up the rpm. Else I get a really nasty oscillating sound from one of the upper bearings.

Here is a video of the spindle at 3200 rpm roughing 6082 aluminum with a long 24 mm indexed end mill.



This has became a favorite tool for roughing aluminum as it has good reach, removes material at a decent rate and the 1003 inserts are cheap and readily available from many vendors.

Individual homing does not work.

Could it be that I am not using the correct version of LinuxCNC?

No, any version of LinuxCNC from 2.8 on will work with the 7I76E

Like I said you need to check


hm2_7i76e.0.7i76.0.0.spinout-minlim  
hm2_7i76e.0.7i76.0.0.spinout-maxlim   
hm2_7i76e.0.7i76.0.0.spinout-scalemax 
hm2_7i76e.0.7i76.0.0.spinena-invert  

 hm2_7i76e.0.7i76.0.0.spinout
hm2_7i76e.0.7i76.0.0.spinena

with halshow

In axis, you can run halshow with:

Machine --> Show Hal Configuration --> Watch

And also verify that you have +10V on the 7I76E SPINDLE+ pin
(TB4 pin 3) relative to SPINDLE- (TB4 pin 1)

 

Fast-forward 3 years, and FreeCAD is over the version 1.0 hump and the topo-problem has been resolved.  Seems many are still finding it hard to use effectively; perhaps a generational-gap between traditional (geometric) CAD and modern (parametric) CAD.

For 2.5D work from traditional CAD, take a look at QCAD-CAM:  www.qcad.org/en/products/qcad-cam
A quick CAM tutorial:  www.qcad.org/doc/qcadcam/QCADCAM_Tutorial_en.pdf

These pages really don't show off all the features and capability... QCAD is the mothership of the illegitimate LibreCAD; a full-featured (paid) CAD package which should be familiar to anybody with old-school CAD experience.  Free trial version available, reasonable cost / you own it, no cloud, no locks.  Import/export .DXF and many other common formats; has layers, line styles, hatching, blocks, extensive snaps / geometry / tools, dimensions, etc.  With the CAM add-on, there are like 50 pre-defined gcode export styles, including MACH and LinucCNC in both metric and imperial.  It also has an ECMAScript (JavaScript) post-processor that can further tweak the gcode to your heart's content: qcad.org/en/92-qcad-cam  It has an active user forum, with currently 43k posts and seven languages supported.
