Hi Hood,
The driver test looks steady at 25020 with the occassional change to 25018-21 for a brief 1 sec or so - the graph looks straight lined with the odd small spikes (very small) appearing every so often.
I have already tried reducing the motor speed by 10% and reducing the acceleration by around 20% but just the same. The stall only appears to happen at the one point in the programme - on a G0 line. I have done a work around with swapping over the two pockets (ie pockets 7 - 8 to 8 - 7) which has seemed to cure the problem and it runs through the programme so far - a few aircuts without a hiccup. But, the G0 is used all over on the programme so why just this one line? There must be something that makes this happen - it has done it in a few programmes which made me start searching for the answer. The computer is a Dell dimension 3Ghz processor, etc so should be fast enough.
