I am running the PWN air cooled 80mm 2.2kw spindle on my Onefinity CNC with the Buildbotics controller. About a week ago there was a firmware update released for the BB controller (V 1.6.1). I read a couple of posts where it was stated that after the update was done, the PWN VFD is no longer in the tool drop down menu. My question is, has anyone else heard of this and if it is true, is there a fix for it? Thanks! ---

The following topics may help you. “…Onefinity Renamed the PWNCNC profile to EM60…” > [@Onefinty BB controller firmware 1.6 w/rotary issue](https://forum.pwncnc.com/t/onefinty-bb-controller-firmware-1-6-w-rotary-issue/2599): > > Hello all, Just an FYI but the new 1.6 firmware from Onefinity Renamed the PWNCNC profile to EM60 - the reason? Because they have Redline now and i guess we get kicked to the curb. from Onefiinity support "The only spindle we officially support is: [https://www.onefinitycnc.com/shop/category/spindles](https://www.onefinitycnc.com/shop/category/spindles) All other spindles are considered aftermarket and we will not be able to provide technical support. Aftermarket spindles may void your warranty."

Sorry for the false alarm. I was unaware of our tool type being EM60. ---

My PWN spindle will not turn on speed after the 1.6.1 upgrade. New sim card reflashed by 1F and the speeds run great in manual mode but not in automatic mode as it did prior to the upgrade. Another reason why i don’t like upgrading, never seems to work out for my items. ---
