My size 42 stepper drive BP sized CNC mill has Z on the quill, but my 55 year old back is tired of cranking the knee up and down so I'm adding an 1800 in-oz stepper motor to the knee also. I'll configure two start up files so I can use the knee for Z for heaving milling (quill locked) and the quill for Z for drilling, tapping, light milling.
So I'm going to have my cake and eat it too.
Ray L., I'd like to put some gas springs on my knee like you did, to you have any model numbers and the supplier info for the ones you bought?
Thanks,
Paul T.
