Hi Ray, i thought many time about changing the fpga code of the MESA card for generating step and dir for steppers. It should be possible by keeping the interface to EMC2 and driving the steppers like servo´s (from EMC2 perspective). This would help everyone who needs to generate a high, accurate

Hi Eric I don't have my mesa card in the fast computer I used for the 71k pps stepper tests but I tried starting up a mesa card inside a stepper_inch setup. Since all of the mesa communication is in the servo thread it does almost nothing to the ability of base to spit out pulses. Certainly cha

Hi all, This is mostly in context with the Mesa M5i20 board. I have a new project where I need to control two micro-stepping stepper motors, as well as a laser. The laser takes a PWM input. I am pretty much committed to the m5i20 for the PWM, but at the same time need to generate 60-70Khz step a
