Ned_Seven,
Any updates on your Gerber Saber?
I just purchased a Gerber Sabre 408 last weekend. What a rock solid machine mechanically.
Previous owner was told by the Gerber Tech he needed to replace the following Servo items Gerber Part #P61544B ($1,680) #P61529C ($532) #P61525C ($507).
I'm still waiting to get access to the Gerber Online support docs so I can look online to see what parts are bad. They sent me a credit application to fill out and wanted proof of
ownership before issuing me a user Id.
to get access to their website. Everything is locked down.
I want to replace/update the current proprietary controller system and add a water cooled spindle.
At this point, I have 2 choices:
1. Re-wiring controls using your method using existing Servos, Machdrives RBR and Centroid Acorn.
2. Replace Servos with DMM DNY4 NEMA 34 ($1400) and Centroid Acorn. If I go this route I need have the Servo brackets machined to accept NEMA 34 motors which means removing ball screw nut.
(I saw pictures Ned had posted of a Gerber Sabre machined to accept NEMA 34 steppers.)
I would prefer No. 1 because of cost and time. Only problem is that I don't know if the existing servo is bad or even how to test it. How did you test to see if your servos and encoders were good.
Thanks
Karl
