Grizzly G0745 Micro Lathe CNC Conversion Y Axis (UPDATED)

thingiverse

@@@@@@@@@@@@@@@ I've added two new files now I'm converting a desktop Micro Lathe into a CNC lathe, it has a machining envelope that measures four inches in diameter and six inches long. This is my very first homebrew CNC machine and I built it as I went along since no plans existed yet :) This isn't finished just yet....but it's extremely close. @@@@@@@@@@@@@@ I've added two new files now Ymount.stl is an update to the original Y_mount file, it has been updated with improved motor fittings and it replaces the metal bridge on the carriage now. Ymount_brg.stl is an update to add a precision bearing that's 8mm OD x 5mm ID x 2mm thick, this tiny bearing has almost microscopic ball bearings (http://www.mcmaster.com/#7804k104/=w2uqhf) This should help stiffen the shaft slightly, indeed it does. Y_Mount.stl is the servo mount for the Y carriage on the lathe...I'll leave it up since I know a couple of users are using it to base their own designs on.... Instructions I printed it with the "Y" facing down on a Craftbot, sliced for .30 resolution and standard printing. Took about three hours now. Printed with supports in PLA (blech)...but I want to print it in ABS so the supports come off much easier. OK...the two new files can be printed on their side. This cuts way down on the support needed now. You can still print it face down, that will give you a nice glossy or matte finish. You'll just have to watch out for the supports then. If you're printing this in ABS...nothing to worry about....supports are much easier to remove.
