Thats the odd part - there is nothing i can find that touches that DRO so it must be an internal thing linked to pulley numbers or something.

Is there an OEMbutton code for the spindle speed override button - maybe easier to just tack that on at the end??

DoOemButton(183)

I seem to recall however that years ago I had issues using that button in a macro on the Beaver mill and ended up writing to the DRO itself, so if there are problems you could try.

SetOemDRO(74,100)

If however you have a pot and have the IP-A set to control the override itself rather than allowing Mach to, then likely it will force it to 100% anyway.

yes i too tried button 183 and it was not happy.

I will have a pot on the CSMIO so maybe that will fix it as you say, writing to the DRO could be useful too if not.

Thanks

Sorted :)

With the help of a much admired friend ;) I now have it working properly.

You have to have two pulleys only,

1= 1 to 3000 rpm reversed
2 = 1 to 3000rpm normal

Using my modified macro attached to instruct which mechanical setting to use, there is now no funky spindle speed override display :)

Ignore the last post, it worked on the simulation but not in reality as the PWM was totally freaked out!

I have gone back to my code with the screwy SSO DRO stuff, i also fitted the SSO pot so the CSMIO had control - it certainly fixes the weird SSO behaviour BUT the range of the override pot is very limited and dependant on the pulley setting - very complex relationship between pulleys, wpm and SSO pot i think.

Still it all seems to play together now, pretty smoothly.
