General Mach Discussion / spindle calibration

« on: January 16, 2013, 04:54:10 PM »

Hi all
i had my lathe spindle set up with pwm output (0-10v) working index pulse displaying correct speed and not that far out with the sword from speeds from 200-4000rpm
then i decided to run the auto calibration to try and improve things- big mistake!

the calibration process completed ok but shows a massive spike at start. for some reason the spindle never started till about 1000rpm+
and now spindle does not respond to swords below 1500. i deleted the lineration.dat and restarted and still the same. I noticed the control ratio shows about 0.01 (as opposed to nearer 1?

is there anything i can do to get it back to its default settings or is it a complete reinstall!?

do i still need to set steps/vel/acceleration in motor tuning even thou it is PWm?

thanks in advance for any help!

PoKeys / po56u and poextbus problem

« on: January 08, 2013, 03:07:11 PM »

i have a problem with the extbus device.
i have an output connected to a relay module (24v relay) and this switches a contactor but no (coolant) motor connected as yet
now on switching on using either keyboard or external button - sometimes it works but most times relay twitches off then on again- or vice versa- only sometimes staying in the correct state as shown on the mach screen.
the relay is well within current limits of the extbus and i cant see how this would affect the load on the bus.
