General Mach Discussion / Missing steps revisited
« on: July 28, 2006, 02:09:27 PM »
I am a newbie to mach2, but have created many models for other cnc machines.
I have a camtronics servo system with g320 geckos and moog servos with 250 count US Digital encoders.
I am running mach2 on an older system 450 xeon cpu. The ocxtest shows 25,600 but when running a program the pulse gets as low as 23,400.
The motors jog both forward & reverse fairly smoothly, yet when the machine does a constant move ( 2” or more) it seems to miss steps (get lost) & run like junk.
In reading similar topics on this site I have come to the conclusion that is either a pulsing problem or low voltage at the port.
Questions:
1. When I check the voltage to the port, should the system be engaged or off-with a program running or not?
2. Is there a dos program that will run with the geckos to see if it is my computer OS that is at fault?
Thanks in advance,
