Hi,


I have just fitted my lathe with an MPG, 4 pulses per click, X/Z switch and X1,X10,X100 rotary step selector this is all connected to the second LPT port.  Now for the issues:-


I used the calibration screen and it gave me some results, 4 pulses per detent, 3.452 and 2.376 saved and reset.  One click send the axis off at some rate and travels about 40mm with the Step/Velocity set.  Why?


The X/Z switch works fine.


The step selector is very odd, I have it connected to 3 inputs set as OEMTrig 1,2 and 3, these are configured as OEM codes 191,192 and 193.  The gen config is set so the first 3 entries of the steps are 0.01, 0.1 and 1.0


When turning from X1 to X10 to X100 I see 0.01, 0.1, 0.01 in the DRO and when going back I see 0.01, 1.0, 0.01 By my reckoning I should see 0.01, 0.1, 1.0, 0.1, 0.01  Why? ?


Also there is no movement in Step or Multistep mode? ?


Please help its driving me nuts.
 
All I want is to be able to move 0,01,  0.1 or 1.0 with one detent.

It sounds like the MPG is being interpreted as a velocity jog rather than one increment per detent. Check the encoder pulse settings and use separate active inputs or a macro for the X1/X10/X100 selector, as OEM codes 191–193 may be cycling rather than selecting fixed steps.
