Request for Mesa 5i23_7i48_7i52 firmware

If your spindle control can set 0 speed as 1/2 way up PWM
than that should work but note that you will get full speed
when LinuxCNC is not running (since PWM would be off)
so you need a separate enable (perhaps from the 7I84).

This mode is supported in the hostmot2 driver for PWM as "offset mode"


 

On changing my ini file to try out this new firmware I get this error:
IDROM IOPorts is 3 but MD IOPort NumInstances is 6, inconsistent firmware, aborting driver load

I've created and attached the report file.

This one should be better:

 
 

That's good so far - existing system is perfectly happy and working as before with the new firmware in; it'll take a bit of time to integrate and check the new functions. Hasn't helped that the new servo drive/motor kit is now doing nothing but fault out, after a working brilliantly for about half a day (nothing to do with the firmware change, it's doing it regardless of how I send it commands). I think I can still try out the alternate PWMgen on my existing vfd.
Thank you once again for your help
