Re: Hafco 12x36 CNC conversion
Nice work. I like your approach to a few of the problems.
I would think your mounts should minimize flex. Didnt you say they are 2" thick? I have a Central Machinery (HF) 12 x 36 and have considered converting. I might have to get around to it.
Is it the photography or is the hole for the X screw off center in your mount? That is quite an elaborate mount with the plug entering the ball screws bore. The 2 bolt holes would have likely been sufficient.
Ok I wasnt going to say anything about your stepper mount for the carriage. I thought the additional plate for the stepper itself with the slots was bulky and an after thought in relation to everything else. Then on post #3 picture #14 down on the right side, there is the mount like I would have liked it. What went wrong with that mount? Not enough clearance of the stepper to the bed?
Also on the pillow block for the X, right where the pulley is. Is that just proud enough over the ways for the carriage to hit it? As in a positive stop? Otherwise over travel would have the carriage hitting the pulley. Wouldnt it?
A lazy man does it twice.
