General Mach Discussion / Re: Offsets and saving.

Not sure if I am understanding this correctly but if you zero all your offsets (offsets page) then uncheck 'offset save' and 'persistent offsets' etc in General Config page then Mach will have no knowledge of previously used offsets when starting up again from scratch.

General Mach Discussion / Re: DC Motor as Rotational axis

« on: March 28, 2011, 03:53:28 AM »

Hi JR,

I know nothing of lathes but the rotating headstock is fitted with a slotted disk which interrupts the beam from an optical sensor. This pulse is then fed into Mach to  measure RPM and is used for synchronizing threading etc. A similar system is used for spindle speed control on a mill.
You may need to do a bit of searching but there are details of spindle setups on the forum.

Hi John,

Welcome to the forum.
From just quickly glancing at your website I think we are all going to be learning stuff from you pretty soon.
That TX ballancer is just brilliant (wish I had thought of that).
Good fortune with your router.

Sorry to keep asking dumb questions but I am trying to establish what you have.

Inside your control box do you have the genuine Microproto controller or is it a Stepmaster board ?

I have run the code and nothing wrong there - all my axis return to their start positions.

I believe the CNC4PC board A25 has 5 Volt outputs but check with them first.

I think what you have suggested is the only way. (without fitting another PCI parallel port to get more inputs).
The probe cannot share a limit / home switch connection it has to have its own input but a home and limit switch can be configured as the same thing.

If your PC has a spare PCI slot you can buy a  PCI parallel port card with 5 Volt outputs.

Under 'Config' check your homing limits.
Is your GCode finishing with a G28 ?
