I have a TAIG with DESKCNC 2nd Gen and Miroproto Driver (Lambdaa Series 1000x)

I'm Losing Steps seems to happen when both X and Y axis are moving.
I wired an external power supply into the Microproto Driver, same thing.
I noticed that the Microproto uses 1 PIC microcontroller to drive two stepper motors.... can it guarantee pulses in a timely manner? I'm wondering if its a flaw in the Mircoproto driver.
