General Mach Discussion / Re: Closed loop system, encoder connected to mach3
« on: June 26, 2010, 11:41:07 AM »
There is a board sold by Ron Rogers that can monitor encoders and throw an error to stop Mach and then I believe update the DROs with the correct position. Its not closed loop as it will not correct until after an e-stop and whether it would save your work will depend on the following error you set and how fast you are cutting.
Theoretically you could do this in a Brain or a macropump but I have my doubts whether this would be fast enough to save the work as the update is only 10Hz and in reality is could be nearer 5Hz as the error could be seen just after one scan so will not be picked up until the next.
As said though it would all depend on how fast you cut and how much of an error is too much, could be fine for plasma or router but doubt it would be good enough for a metal cutting machine where tolerances are usually much tighter.
Just my thoughts on the subject.
