I have a Gidget table and the lift is on a chain. Be sure the machine shelf is level It's very hard to micro lift perfectly. I managed to get my older Bernina to fit using the extension table that came with the machine while sitting in the table. My big Arrow hydraulic lift is the same way. Very hard to microlift just a smidge needed to be perfectly flush with the insert. I got it to fit flush by using a machine mat under the machine. The tables are wonderful but in reality not as perfect as far as the inserts go as one may think for all machines.
