Mesa 5I25 conversion

Hello everybody,I am currently converting the control system of a CNC machine to use Mesa components (5I25 with 7I76). At this point, I have some questions regarding the serial connections for Mesa components.The machine currently employs Leadshine DM556 stepper drivers with RS232 interface. Is it possible to control them using RS-232 from Mesa components, or would it be advisable to switch to a direct control method using STEP and DIR inputs?Furthermore, the spindle is currently controlled via SPI. Is there a compatible connection card available that would allow me to maintain the SPI connection with the Mesa 5i25?The machine features a custom-built coolant control system using I2C. Is there a feasible way to interface I2C with Mesa components?I would greatly appreciate hearing your opinions and insights on this matter, as well as any relevant experiences you might have.

 

There is no easy way to use the RS-232,SPI or I2C interfaces with the 5I25/7I76
hardware. I would just use step/dir and 7I76 field I/O for coolant and Spindle control
