MPG-Mode Question..
« on: December 08, 2006, 05:53:00 PM »
Hi,

I`ve a little bit problems to understand the MPG movement modes... ???

In velocity mode my axis runs in dependance of my turning speed - ? ok!

In step / velocity mode my axis moves at lower turning speed with the set step-size from cycle step mode?
At higher speed it switched to velocity mode, as calibrated or set in MPG-Setup.

But my steps are independant of the cycle steps setting and not fine enough to touch a surface or an edge..
My settings are 4 Imp / detent, vel 100, 40%..

Whats wrong??


The single / Multistep modes are ok, but to slow to jog over the whole table..


Thanks and Greetings,

Wolfram

That is why there are two modes... Art and I have talked a bit about putting the two modes together but there are problems with trying to do that. The problems all go back to under powered machines.

Thanks

Hi Brian,

ok, thanks. So I have to build a new jog wheel with the
function to change the cycle steps...

But..

"The problems all go back to under powered machines."

what does it mean?

Thanks and Greetings,

If we were to do a true electronic gearing of the MPG to the motor you would be able to out accel the motor. The larger machines get past this by having VERY large motors. We send out moves that have the accel and deccel built into the move so users will not suffer missed steps.

Hope that helps
