Well, it was 99.9% ready to run. I rebuild nothing. The machine was said to have cut 2 parts and based on the chips on the grease I believe it. 1st off someone scarfed the digital video card. then the dual com board wasn't seated correctly or installed in windows. the 3 nine pin connectors from each servo apear (and according to aerotech) to do nothing. There was a mach 2 demo installed. It looks to be a very professional retro using quality components.
I now have "axis 4" on the program run screen but ony x,y,z setup in port&pins. I do not remember it being there earlier.
The knee (not spindle). no it WAS working perfectly. yes, PgDn moves it UP. NO - the Z- jog moves it DOWN, but way too fast.
When all was working at 45kHz it was around 20,000. I'm runnning 25khz (since upgrade today & haven't officially retuned) now and even with ridiculously LOW #, it still moves way to fast. I'm talking like 100 steps, vel & acell all the way down to 1 !!!
under motor outputs dir active low is OFF for ALL axises. Step low active is CHECKED for all as well.
After I enter the code, a few seconds later the table moved DOWN FAST.
Thing is...when my z moves this fast, it makes a horible screeching sound that we can't identify where it's coming from. The locks are off, the ways aren't getting gouged, everything is well lubed including the screw. I do not let it make this noise very long...which is why I didn't answer your question about the feed DRO yet. IT says .45 when I set steps to 2000, 4.9v 31 acel. it says about 10 in x&y
There is a couple second delay when moving the z axis not present in the other 2.
As a bald guy, I'm REALLY frustrated! I did BTW install 2 small programs before this happened. Autoeditnc and cncsimulator. Both free utilities that should" have nothing to do with this. Other than that the PC is quite pure down to Arts exact instructions of a clean xp which got my "pump" relay from clicking on & off a million times a minute.
