We're sorry to hear you're having this issue! Please send pictures/video of the wobbling to info@safejacks.com and we will work with you to determine where things went wrong. Thank you!
love the concept, take my money after you please stop using plc for the guides. They will crush easily that will cause wobble. At least use ABS or ASA, and you really want to use some type of metal, probably same type that is used for high impact airtools
