Re: [CAD_CAM_EDM_DRO] Re: BOSS5 to Mach2/Gecko

How do we detect lost steps without a DRO? Set handwheels on zero with software zeros and run for a while then referencs software zeros and the handwheels return to zero everytime. Using servos on my Bridgeport it has never lost a step. I've checked it so many times, I dont even bother anymore. To my knowledge it's never lost position.

I've no experience of anything else, but it does what I want. I get
about 80 ipm rapids (reliably, it will go faster), it'll drive

some fairly heavy cuts without losing steps.





Hi, that brings up a question for me. I have a Bridgeport Boss5
converted over to Ahha. I also have a DRO attached to x and y.

My question is with a non feedback system, how do you "see" the lost
steps. I can see them with my DRO display beside my ahha computer
display if it happens. But without that how do you see the lost
steps besides an out of tolerance part?

Just curious how others deal with it. Not curious about how to
prevent the lost steps just how you are detecting them.

Thanks guys, JRouche
