Chris, I found the solution in another thread you responded to. ( [PWN Spindle with Openbuilds Blckbox Controller - #5 by Chris](https://forum.pwncnc.com/t/pwn-spindle-with-openbuilds-blckbox-controller/1820/5) )

I set the P2.0.13 setting to 0.3 and this solved the RPM issue.

Thank you for the help!
