My 2007 shop sabre with servos has developed some behavior problems.
The machines problems started out with the z axis not stopping during setup and crashing into the spoil board. I thought this might be a one time thing or that maybe operator error was the culprit. Next problem the feed speed pays no attention to the programmed speeds (even when testing with old files that used to run fine), at 200% the listed speed is 600 or more always and somtimes the bottom speed is higher then the 200% speed. Next up and this is a doosey, the tool touch command has always ran at a default speed, now it runs at program speed which it thinks 600 ipm or higher is a good speed. The last time I used the tool touch the spindle took off like it was on fire and ran past the touch switch and maybe would still be going if I had'nt installed crash limit switches.
That last fiasco caused me to stop using the machine till it's fixed. I'm concerned for the machines and my health, if trys any more tricks who knows what might happen.
I ran a new version of AVG V.8 and there were only some cookies that were cleaned up, no serious problems were found.
I think the problem lies in the Wincnc software.
Anybody have any experience like this or know a possible fix?
I have contacted Ben at Shopsabre and expect his reply shortly, he has been
helpful but the problems seem to be moving around.
