Retrofitting mill and a lathe: Hardware recommendations

I have 3 machines I would like to upgrade from Mach4 to LinuxCNC:
- Wabeco F1210-C hs
- Wabeco CC-F1220 hs
- Wabeco CC-D6200 hs

One is running Mach4, other older proprietary unknown to Google systems from Germany. All systems are equipped with stepper motors and 0-10V spindle control with CW / CCW. Two of the machines have tool changers. All mechanical components are metric.

My wish list:

• Same components in all cabinets
• Easily port / adapt PathPilot 2.x
• Stable production ready machines

Components:

• Mesa 7i92H Anything I/O Ethernet card
• Mesa 7I76 STEP/IO Step&dir plus I/O daughtercard - Sourcing output version
• Mesa SPINx1 PWM (for spindle speed and cw/ccw)
• Phoenix Contact PLC-OPT 24V 2900364
• Linear power supply, 36 VDC (re-using existing)
• Leadshine EM556S or EM870S for X/Y/Z axis
• Leadshine EM542S for tool changers

I'm quite a new to the game, so would really appreciate feedback and comments.

As a general rule a 7I76E is a better choice than a 7I92 + 7I76
(more expansion capability and a a bit cheaper)

Also depending on how existing output devices are wired you may find that a 7I76ED
(the sinking output version of the 7I76E) may require less wiring changes

Thank you so much, I will look into 7I76ED - it will indeed be less wiring.

Yes 7i76E is very great card with built in spindle analog isolated control but be carefull that does not support to use +-10v for spindle control this one only support maximum 15v range ! (I think SPIN1x does not allow to use negative analog and the rang is 18v max.)

For my lathe i have use a 7i83 for spindle control.

Very beautifull machine you have !
