Hey guys need a little help. This is a new item for Grizzly. It looks interesting. It says it has a 4a drive motor. I cannot find what size stepper motor that is. Does anyone have any experience with this unit or one like it? Sherline has one that looks close and it is a #23 framestepper motor. I know it is not big but just to index it does not have to be. I thought I might remove the stepper motor and controller and adapt it to my larger rotary table. Thoughts,suggestions?
