General Mach Discussion / Controller Frequency Setting

« on: October 15, 2012, 09:32:52 PM »

Just getting started and noticed a problerm.... while in MDI and dumping in coordinates and the wait time for actuation to begin is 1min+ followed by an error code about SS frequency being too high for computer to understand.   Message recommends lowering to 1khz or 500 mhz.   I lowered it al the way to 250 and got long waits and proper motion, anything higher and error messages......

What's reasonable response time?

Thanks

Yep,  Under the Bus with the Boy!   At least you're the only one on Earth that knows!!!  Don't tell his mother  I said that though... I'll deny everything!!!

Cheers and Thanks Again for your consideration of my problem!

Gentlemen,  I'm going to blame my teenage Son with whom I entrusted soldering and heat shrink tube installation......I found my problem!!!

Thank you very much for your responses and help!!

Lastly, can you point a Newb to a thread where I can learn how to get her milling?

Cheers to all,  Scott

Well,  reversed the Motor Output pins from X(2,3) and Y(4,5) to X(4,5) and Y(2,3).     Manual actuation changed on the keyboard - previous X arrows and Y arrows swapped functionality but random direction changes remain on the X stepper (albeit somewhat less frequent which doesn't make sense to me).

I guess I'll re-inspect all wiring points and await another idea...

Cheers

Gentlemen,  I've adjusted the SS filter(s) down to 1.43, confirmed wiring OK and switched axis' to track problem and....... I've still got the problem!

It seems to me the problem is upstairs in Mach3.   Once again if I press X+ repeatedly the motor will change direction in a random manner.

Upon Homing, Z/Y perform flawlessly and when X ho,ming begins the motor just sits and growls, like its getting X+ and X- instructions at the same time.

I'll double check...at first I thought it was my dodgy soldering so I sacrificed a db9 cable and spliced into it to eliminate the potential for the problem...Thanks

Good Morning Hood,   Actuating the X axis by mouse or keyboard generates random directions changes.    For example if you repeatedly press X+ you get random direction changes.    Yes,  I moved the pigtail to the Y axis and the problem remained.

Any Thoughts?   How is the weather in Scotland?!
