I worked on this a little this weekend and I also reviewed the suggestion for using the encoder board from romaxxcnc.com. The romaxxcnc board cost $159 more than I wanted to spend at this time and at this time I am only concerned with 1 axis.
The first few steps I have done to get this going was to get an encoder working with Mach3 then couple the encoder to the motor, and finally calibrate the units for the encoder and motor. The next steps will involve having the software compare the data from encoder to the DRO in Mach3. My thoughts for the software is to modify the home sequence of the z-axis to zero the encoder to get the Z machine position equal to the encoder position. Then have the comparison done in Mach3 Brains. But at first I may do the comparison in a Macropump because it may be easier for me at this time.
Is there much of an advantage to using a macropump over doing the comparison in Brains? My original thinking is that Brains run faster.
Thanks,
