Another "what do I need" thread. Vmc retrofit

Example:

Halshow, halscope, sim_pin and other applications useful for testing can be started in
an ini file too

As I think that the custom HAL component will be generically useful I am happy to write that, if you are happy to test it

If you take the time to write the code then I'll absolutely test it!

I was reverse engineering the spindle encoder today. I found A and B but I don't know witch is witch but I know witch is the index.
So I now have a 1024 line encoder on the spindle. Should be 4096/rev.
That solves the spindle orienting right? At least mechanically. The spindle drive is +/-10V so that should not be a problem to hook up.

I translated some of the original documentation I got with the machine.

Is it a bad idea to use a Arduino in you guys opinion?
If I went that route Linuxcnc would only need to position the spindle then tell the Arduino what tool is selected and move the Z axis when needed. I could also add a display for debugging and maybe show load on X/Y/Z/spindle as a fancy bar graph

I really appreciate the help I'm getting here!

Hi mr who
I think you chart is wrong if i follow that right the arm would crash into the spindle ,..
I made for better read an script which is called for tool change i just posted it in here

first i check if tool pocket actual is ok you might be able to rotate the carousel !!
i put all in sub ngc files for better maintenance because from comp to drive Z axis was not possible for me ,..
Spindle stop

get Z axis out of their way therefore i have a subprogram called get_put move
Then orient Spindle wait and Check M19 Stuff this is what you need to get with your encoder done !!!!
Move Z axis in right position for change (if there is an tool in )
then arm_danger means arm goes forward where it can collide with spindle
release the tool
move z axis up
then i set switches to call my component which does the real time for rotating the carousel in right direction (shorts way) error handling to ensure right position for pocket
of course all with error handling
then i open collet go down
set blow relays for cleaning the taper
then close collet
put arm in save position

proceed with cutting
