ECMO VMC100 Retrofit with Carousel/Toolchanger

Hi guys!
I get a VMC-100 as gift from a school.

I owm a F1P which i retrofit to LINUXCNC years ago. works perfect.
Same Machine as the VMC-100 but with manual Toolchange.

Now the VMC-100 has a carousel as Toolchanger.

 

This carousel have 4 proximity switch to operate the Toolchanger.

 

Sensor1 is a sensor to reference tool 1.
Sensor2 counts a hole in a parallel gear. is it counts 2 times the next toolslot is reached.
Sensor3 tells that the tool is engaged.
Sensor4 tells that the tool is disengaged and the mainspindle can rotate the carousel.

 

Main issue for me is that the carousel works above the Z reference sensor.
At Z reference positon the Carousel begins to disengage the tool and when sensor 4 is reached the carousel can rotate.

Does someone ever retrofit this in Linuxcnc and can share his experience?
I searched a bit arround but found only some videos with MACH3 and some dead threads.

I will use the orignial maindrive which has a encoder on it at the beginning.
the maindrive works with step/dir signals.

On my f1p was the same maindrive which i use to tap threads.. spindle orient is used for this but iswitch to a 1kw servo.
this time i will use everything orignial because i have 3 orignial stepperdrivers for the 5 phase steppers. later i would change to nema23 2 phase.
Main focus is to bring everything back to live without changing to different steppermotors or maindrive.

The maindrive is working and the encoder counts.
Steppers working.
all proximity sensors are working.


thanks for any help
