Well, I recreated it and confirmed cycling VFD power without rebooting LinuxCNC makes the spindle run again. I looked into the HAL after the "Spindle CW" button breaks everything: enable TRUE is_alarm FALSE is_at_speed FALSE is_ready TRUE is_running TRUE reverse FALSE run TRUE watchdog_out TRUE

Re: [Emc-users] Spindle control panel breaks LinuxCNC?

It's modbus, sorry forgot to mention that. What baffles me is the Spindle buttons on the panel, AFAIK, just map to the same spindle-run in the HAL that M3 goes to. I remember looking at the HAL monitor on this weeks ago and IIRC it was "spindle run true, but spindle-isrunning false". The

Re: [Emc-users] Spindle control panel breaks LinuxCNC?

very difficult without a crystal ball you'll need to post your complete config folder as an archive somewhere , not just snips . so we can mimick your installation . it could be you have the spindle enable reversed in hardware , hence it works but not from the gui . ( easily done ) use the hal

[Emc-users] Spindle control panel breaks LinuxCNC?

I have an X200 VFD. M3,M5,S18000 work fine, from MDI or code. My MPG's "spindle" button works. On the default panel, there's a "Spindle" button flanked with a CW/CCW indicator. Clicking any of that doesn't make the spindle go, even with "S" set to a valid RPM. It's not JUST that. Once you

you can use stepconf to produce a configuration , you usually see a sets spindle-at-speed true , this overides the spindle at speed it may be in your postgui.hal file . comment it out and you should be ok On 29 December 2015 at 14:59, lloyd wilson wrote: > I'm

[Emc-users] Spindle control

I'm trying to add a pyvcp panel to control a spindle vfd. To take advantage of the 'at-speed' signal from the vfd to inhibit motion until ready, the motion component of LCNC needs to be aware of the spindle command state- from the documentation: *motion.spindle-at-speed* IN BIT Motion will
