I recently upgraded a STG driven CNC mill from EMC1 to EMC2. Homing on an index pulse didn't work for me. I ended up setting the "home on index pulse" parameters for all three axes to "NO" in the .ini file. Luckily a precision home position wasn't critical to my client, but it is a loose end... Also, the estop control logic is slightly different in EMC2, not necessarily wrong, but different. In EMC1 the ESTOP state would change to ESTOP RESET only after pressing F1 and setting the "estop write" bit. In EMC2 you go to ESTOP RESET as soon as "estop sense" is OK (the estop chain is all continuous). In EMC1 the F1 key would toggle "estop write", in EMC2 you have to break the estop chain to get from MACHINE ON to ESTOP. Like I said not wrong, just different. Finally I've found that keyboard jogging in tkemc is jerky. Starting a jog move seems OK, but upon releasing the key the axis jerks to a stop rather than smoothly decelerating.
