Mach3 MPG is loosing steps in slow speed
« on: February 22, 2025, 01:25:03 PM »
Hello,

I have connected an MPG on the 2x5 connector of Mach3 USB Interface Board with RNRMotionController. While in Function Cfg's -> Calibration of MPG's, "Cal Detent size" all clicks of the encoder are detected as detent/counts no matter what is the speed I rotate the MPG. Even a single click with very low rotation speed is detected (I see the counts increasing). When in MPG Mode in Velocity only or Step/Velocity the slow clicks do nothing but if there is a sequence of slow clicks after the first few clicks the rest are translated to move. In Single step mode the mach3 is not responding to kind of speed of clicks. In Multi-step mode there is a response on a fast rotating speed of the encoder with a delay of a few seconds.

Can imagine what is wrong?
