I decided to upgrade my old ShapeOko 2 to a larger CNC, and I have been buying parts when I have the money, I started getting parts to do this upgrade years ago, but got distracted with other projects. I wanted the ability to cut a 4x8 foot sheet of plywood, but I just don't have the space for that, I do however have the space for a 5x5 foot CNC router, and I already have a nice table made just for that. I have a Bosch colt on my ShapeOko 2, unfortunately even with ear protection it's just far too loud, so I ordered a 1.5KW 220v 400Hz 24000rpm Air Cooled Spindle ER11 spindle. I need a good 65mm mount for my spindle, I have seen a few that don't look too good or that you have to drill your own holes for, I want something good but not over $60, any ideas? I now need a VFD, and to upgrade the ShapeOko 2 to handle the 6 pound spindle. I am thinking about a HUANYANG HY-Series 1.5KW, 220V VFD for my spindle, any other VFDs around that $140 price range that are better? Years ago I ordered 6 pieces of 1800mm MakerSlide from Inventables, back then it cost me around $300 with shipping, my thought was to have a ShapeOko 2 style "X carriage" on each side of the y-axis, I had even got the extra ShapeOko 2 "Motor Mount Plates" that would allow me to use extra v-wheels and support more weight, unfortunately over the years I cut one piece of the 1800mm MakerSlide up to make a 3D printer, so now I only have 5 pieces of 1800mm MakerSlide. I am thinking about OpenRail, and something like a 1500mm piece of V-Slot 40x40 Linear Rail for my X-axis, but I need to find out what spacers and bolts I will need for that, I did read that someone called "EliasPolitis" over at the inventables forum upgraded his X-Carve like this and used 3mm tall aluminum spacers for that, and that they "expanded the X-axis slots on the Y side plates", I also have the X-Carve X-Axis carriage and Y-Plates but never installed them. I have some 7-hole aluminum joining plates that I was going to use has "mid span supports" for the Y-axis rails, or I might use some aluminum extrusion under the MakerSlide. I want to upgrade the Z-Axis, I honestly never liked the ShapeOko 2 Z-Axis and it always seemed to give me problems, I am thinking something like the "C-Beam Linear Actuator Bundle" but that will likely be a later upgrade. Thanks for any tips or ideas!
