As i'm sure you'll be able to tell, i'm new to LinuxEMC, recently got a Gecko G320 servo driver and was testing it out. Once it gets moving a certain speed the servo stops in its tracks and the interface says ESTOP. There is no feedback so I know it's the software stopping it for some reason, is there a MAX speed set somewhere that would do this?

It used to not do this, then I changed the max speed of the X axis (the servo i'm just playing with) upto like 40, just to see how fast I could get it turning. All my numbers are not setup in proportion to anything, so 40 means about nothing. Regardless after I did this once it gets going i'd estimate 200-300rpm it stops.

I guess I just need to read up on the emc config file...

Thanks in advance,
Ross

You are getting a following error. There is feedback in the parallel port driving code, EMC asks for a given velocity and the parallel port isn't able to keep up with it, so the position it reports back is outside the following error tolerance. I believe you need to drop the max velocity until you stop getting following errors. You are hitting the max capability of your computer.

That's interesting, my computer is an old 1.2GHZ athlon, from the thunderbird series. What speed computer do I need to get in order to maximize the speed I get from the parallel port? Is it basically just speed of the puter or is there a special parallel port that I should concentrate on?

I might just buy a cheap 2-3ghz emachine at best buy, you think that would allow my servo to travel faster?

Thanks,
