I did send a message to support, but I thought I would seek input from the incredible knowledge base here, too. I’m busy preparing for a vending booth at the upcoming 2nd Star Festival in Oregon in a week and a half, wand suddenly my machine started making a new strange sound.
Attached is a video of the sound that my GF pro just started making and it has me concerned. Everything seems to be working, but it started making this rather high pitched whining sound (seeming to come from the right side of the GF pro as I face it but I can’t be sure) in the middle of a job, and it seems it could have a problem. Thanks for any insights anyone can offer.
