When I had the velocity set to 200in/min I couldn't go above 5% in the slow jog % box in the manual screen. Since I have lowered the velocity to 10in/min and the accel is set to 0.5 in/sec/sec now I can go to 100% but these numbers are academic as the overall velocity is no higher than before. I hope this makes sense cause i'm confused as hell...lol.
When I say everything works fine, this is what I mean. My lathe is only 14" across the bed so 10 in/minute is slow but workable. I would have thought that for a rough cut I could have got 20-30 in/min but i'm no expert in machining. I'm an electronics man, not a turner. It's just something I fancied learning.
I should also add that i'm working with delrin 150 so I should be able to go quite a bit faster than working with alloys.
Also, my steppers are only 1 amp rated, I suspect they are underrated.
Cheers
Phil
