Since so many people have been having so much trouble with the YRR Roller accessory, I have created a complete how-to video and PDF guide. It is important to note that the Ortur control boards come in different variants. Some are compatible with LB machine settings and others are not. These instructions address how to deal with both.
Don’t skip forward in the video! I know I’m boring, but skipping forward may result in missing key information!
Here is a link to the pdf file that you can print to set yours up: https://lahobbyguy.com/forum/yrr I highly recommend watching the entire video at least once to digest the information, and then printing the pdf to setup your rotary.
