I am just curious, as I ve pm'ed Ihavenofish and he mentioned he was able to increase his rapid movement to a certain point before it would just plain stall and not operate.
I believe he mentioned 130ipm or 135ipm as the ceiling.
Well I just thought I would mention that while working with mine, we had the feed rate at 160% over ridden and when it hit a rapid move , it shot right to 160 ipm ( I have mine set to 100 ipm in the config files ).
It ran 160 ipm without a glitch for the short time that it did so before I realized what happened.
We replicated the "problem" again , and again no issues. It didn't seem to miss steps either. But we didn't run an entire program at 160 ipm. I tried it at other levels lower then 160 , again not a full program.
It ran smooth as silk at 160 ipm. I am going to try and set it up and run a program at that rapid speed just to see if it does miss steps or what happens.
If it works at 160 ipm , then I'll try a little higher till it stalls. It would be great to get 200 ipm rapids out of it reliably ! I be happy with 160 ipm rapids as well. I know rapids aren't the main concern as feedrates are and there isn't enough spindle speed to take advantage of the rapids cutting soft materials.
But I'll report back when I get the rapids ironed out and what speed I have them at.
