Hello All. Started to carve the pattern I uploaded yesterday here:
When it came to the V carve segment, the spindle slowed down and went to the centre of my workpiece. I could not find the issue and one of the messages from CM was change spindle which I have never seen before. I clicked resume but it carried on towards the centre of the workpiece and at the slow speed illustrated in the short video link. I am running the spindle at 18,000 rpm.
I have no idea what the cause may be so I created a text file and its behaviour was identical except for the change spindle instruction. I have attached both CC Pro files and both .nc files. Any assistance would be welcome. The 30° Amana bit in the toolpath has been used successfully previously.
