Re: [CAD_CAM_EDM_DRO] Losing steps

Hi Jon:

>>>Of course a true servo system would detect this automatically, as it
>>>checks

actual vs. commanded position, say, 1000 times a second, and will go to
e-stop
immediately

It should be noted that alot of people still get lost (gained really)
steps in their servo systems due to noise on the
encoder lines. I've seen this is many situations this year. It can be a
bugger to track down because
its always assumed that servo's cannot lose steps. Just thought I'd mention
if someone appears to be losing
steps in a servo system, its a good place to start looking...

Just thought I'd mention it, don't get here as much as I'd like lately
..too little time, too much code..
