They seem really close to resolution. Now we only need to accomplish two remaining things:
Get the 15" I series Puma 2100 to kill the spindle and coolant when a load monitor break happens (so the operator doesn't keep seeing high pressure coolant and hearing motor noise which can make the operator think the machine is running).
Get both 15" I series controls to load monitor spindles.
I agree the 31I is a lot faster and a better control, but I have some hope that with AICCII and these simple issues worked out the I series will be able to compete. The AICC II makes the I series a little more competitive but it more like half closes the gap in performance. The AICC II by the way showed that huge improvement on a dynamic milling path G17 face milling the main spindle. When we ran the program currently in that machine it only made a 2 second difference (because the milling moves on that part were simple thread milling G12.1 and linear Y axis flats. So it's particularly challenging dynamic milled geometries with a few thousand lines of code that AICC II will save tremendous time on.
