Need Help!- independent-universal THC device

[PromaElektronik]

Hi, My name is Lukasz, i'm from Poland. I'm Sorry for my english. The DIY CNC plasma cutters are not widespread in Poland so I can not get help. in connection with questions from my clients i need help with the project Z-Axis driver plasma complette controller built on the my Compact THC Controller.

My main assumptions new project:
1. Integrated Stepper Motor driver (or only step/dir signals)
2. USB/opto RS485 interface
3. Small PC software (management of groups of parameters)
4. Inputs : my THC controller, Torch On (from PC),THC(voltage control) Enable? (from PC), material sensor (switch or diferent sensor), axis limit switch
5. outputs: Torch ON, ARC OK (to PC) and stepper motor.

I seek user (maybe more users), who wants to help create a prototype in exchange for the finished product. All my new products have the ability to firmware UpGrade, should remote collaboration not be difficult.

I care That the device was universal and capable of being mounted in a variety of CNC control systems.

but in the beginning I need to know your needs. This will be the device for you, not for me .

Most important is unfavorable opinion - what is wrong with my assumptions.

Please, a lot of reservations

EDIT:
I forgot to write: my time zone is different than the U.S. so I can write off on a strange time.

It seems very simple in construction. (compared to other controllers as my company produces for individual orders ).
