Ok if the spindle speed is as requested then thats fine. I always did things a different way to the way Greg said but I think the end results were the same. Talking about this has jogged my memory
Step/Dir spindle control from the SS and ESS has never been perfect and Greg always said he would have a look but sadly never did as obviously there were other things that affected more people that he worked on instead. Anyway what that brought to mind was I had similar issues in some plugins and went back to 10a plugin. What would happen is the spindle would be running fine but if there was a heavy load on it all of a sudden it would E-Stop, so kind of sounds like it may be a similar thing to your problem. Maybe try the 10a plugin and see if it helps.

Hi Hood
Hmmm, what you say would make sense of what is happening, and FYI I did try the 10a plugin and that didn`t help, there are a couple more plugins between the 10a and the one I am using, maybe I`ll try those as well
Based on your thoughts it may be that the higher the spindle runs the more it would sort of emulate a higher load, I`ve only been cutting light on Aluminium castings with small 3mm end mills so very low loads being generated
If it can`t be fixed then I`ll have to look at using a different motion card for the Mill, I have a small Lathe that would be fine at those rpms so the ESS might be OK for that if I were to look at doing a Mach3 conversion on it, I do have a Galil motion card and I/O unit that I bought for a different project so may go along that road when I have done the current workload
All very interesting stuff for sure, steep learining curve though
You got any reccommendations for motion cards ? ? ?
