Wow! I have to say, "FREAKING WOW!"
Yes, you can quote me on that. I just got the first axis working on the new DuGong 16035 drivers. Once I figured out everything I was doing wrong and got it setup right I did testing upto 450 IPM where it faulted. I was testing on X which is not the heaviest axis, but its certainly not the lightest. At 300 IPM (a good speed for a mill) I had it running at acceleration rates upto 80iss. No, that's not a typo. I imagine I could accelerate it even faster. No faults at that acceleration, but all 2 tons of the machine was shaking with a torture testing code file running. I have a feeling my limitation here is that the servos only turn about 2000 RPM reliably under load at the voltage I am running. That would be about 400 IPM. I decided 300 was fast enough. Its fast enough to shake the machine with rapid reversals at even the 30iss I am leaving it at until I get the other two axis going. If I can get 300 and 30 with such a huge safety margin out of Y I'll be thru the roof.
HOLY FREAKING CRAP! Its like a whole different machine.
Of course I only have one axis going, and I have to wait for a new HEDS module to arrive because I broke one of the pins futzing around with the Z axis. I am pretty excited at the moment though.
