Gary:

This is the info I was looking for. I was struggling with the torque requirements and various motor types. I think I am going to go with an acorn controller and Gecko drives just to get things moving.

We are really excited to get this beast (shopbot) moving again!

For one of the old 2001 shop bots like we have, what motor/drive combo would you suggest (that won't break the bank)? I am sold on the acorn controller, just don't have the CNC chops to sift through the large selection of stepper motors out there. I guess one big question is the torque rating for th...

Gary: Thanks for the comment. The machine is pretty much an unknown at this point, and I don't know what shape the motors are in. As part of the learning process, I would like to get the motors moving and see what happens. I guess I should choose the motor drives and power supplies carefully so I ca...

I agree with the Gecko Drive Stepper Motor Basics documentation suggestion. I am sure I will be going over that a number of times. A couple more questions: 1) Does anyone think it is worthwhile trying to reuse the old motor drive that came with the Shopbot (along with an Acorn)? I am going to look i...

My finger is hovering over the order button for an Acorn and a Gecko G540 drive. We just purchased a shopbot that has the PK296A1A-SG3.6 motors for x and y. I need to double-check on the z-axis motor as my pictures don't show it clearly. I am trying to come up to speed stepper motor drives as quickl...
