Machine - Hurco Hawk 5M
During the calibration 'shuffle' which seems to be in the order Z axis, X axis then Y, occasionally the Z axis would not calibrate with the resultant 'error positioning to marker on axis Z'. This would happen maybe 1 in 10 calibrations but when calibration was achieved all would be well.
Now what has happened is that a similar error message 'error positioning to marker on axis X' is happening on axis X but all the time. All axis can be moved using the jog controls, the encoder readouts look good and I can see the marker 'dot' for each axis except for the X axis. I swapped the servo cards around without adjusting anything and the X axis card would not calibrate in any other axis position although it looked like it was trying to. i.e the table would move to the limit switch and move forward to (not) find the marker and then throw up the error message. I read the previous thread 'lost Y axis marker' but I think it was for a different machine as although there is a bal pot the wiring must be different.
Any help on this would be appreciated
