General Mach Discussion / Z Height Setting Woes
« on: February 01, 2013, 06:20:43 AM »
Hi,
We have a few machines running mach3 and using both big tex and gerrys 2010 screens to set the Z height (we set the height using the plate manually at every tool change).
We keep having random problems on all machines whereby every so often the tools do not retract from the touch plate and push themselves down hard into the plates, this sometimes chips the end of the tool. We never have any limit errors or home errors and sure no noise exists in any of the machines, we have tried altering the debounce values however this makes no difference as the problem still randomly occurs so we leave now leave them at zero.
It is a really annoying problem and I wonder if anyone else has experienced this? The touch light is rock solid on all machines and from what we can see there's no obvious problem why this occurs. As the problem exists with both screens (only every now and then) I see the problem being elsewhere, although strange how it is on all machines.
All of the machines operate faultlessly, no missed steps on the stepper machines and no positon errors on the servo machines, just the annoying touch plate error every so often on all machines.
If anyone has any advice it would be much appreciated.
Thank you very much.
