What is happening here?????

I am using RatOS with the BRS engineering 4WD upgrade. When I try to run a resonance test the print head is moving ±20mm left & right. I can also hear the frequency increasing like the plane engine reving up. Any ideas what is happening & how to fix it???

Really, I have only ever seen them vibrate about <1mm

Yeah, the resonance plugin received an update some months ago

Okay, thanks for letting me know. I kept aborting it as I thought something was going to break.
