I have an old flame cutting machine ( 2 axis - BLDC motors ), this machine is controlled with an old controller , It is used to cut steel palns.

I want to replace this old controller with a new Computer based controller, and I found the DSPMC/IP controller sutable since it can controlled through the ethernet ( the machine is 2m * 8m and I want to controll it from the upper floor).

I want to Interface this controller to the motors, and need help :

what kind of encoders to use with this DC motor, Or I can control them with out encoder (I have two tachoMeters)?

I have made a PWM DC Driver befor, Can I use it to control this motors through DSPMC/IP or I should buy a specific Driver?

Can I use EMC2 to control the DSPMC/IP Or I should use Mach3?

What model of DSPMC/IP I should use to control just two DC motors?

Thanks
