    Can I BUY it from you so it doesn't get trashed?C64, real ones, can carry a lot of memories from good teenagehood time for many peoples, and working C64 are getting rare now.

    Modular DIY CNC V2

    Hi !I am SUPER interested in this instructable as I wanted to build a CNC for myself for a long time.However, I understand that planning avoid spending on the wrong design, and while this is V2, you already suggest ditching the belt for a thread transmission, and also use Nema23 instead of Nema17 for more torque while milling.I was also looking on the net for a design for a tough CNC, with a better accuracy than what belts can provide, especially when milling metal. We slide away from real DIY as we must reuse existing components (I don't feel like etching my own PCB and soldering resistors, capacitors, small electronic components, to do what a manufacturer can provide for a reasonable price). I found that planet-cnc.com has some great hardware for stepper motor controllers, up to 9 axi...

    Hi !I am SUPER interested in this instructable as I wanted to build a CNC for myself for a long time.However, I understand that planning avoid spending on the wrong design, and while this is V2, you already suggest ditching the belt for a thread transmission, and also use Nema23 instead of Nema17 for more torque while milling.I was also looking on the net for a design for a tough CNC, with a better accuracy than what belts can provide, especially when milling metal. We slide away from real DIY as we must reuse existing components (I don't feel like etching my own PCB and soldering resistors, capacitors, small electronic components, to do what a manufacturer can provide for a reasonable price). I found that planet-cnc.com has some great hardware for stepper motor controllers, up to 9 axis, which is great when some axis are redundant (XYZ using 2 motors each for a very strong portal-type frame, parallax free) and AB axis doing a true 5 axis motion. You can find some from bang good or eBay too, but would get no support after your purchase.I have a big metal lathe, a cheap manual vertical mill, having a good CNC 5 axis mill is my next investment, which , as a DIY, with Nema23 motors, 2kW spindle and controller, chassis, I estimate the cost to a 1000$+ so still making sure I get the design right before i put this amount on the table. If I am wrong, I could reuse the motors and spindle, but maybe not the parts of the frame.Your frame design is great, especially you anticipated on the risk for a play on the axis. I would happily reuse it, with a higher Z portal allowing a bigger build size, as well as a AB axis holding the spindle.Finding a compact design for a AB axis arm fixed on the Z platform, holding the spindle and not bumping into itself when turning the axis, is my next design challenge :) I saw some "4th axis" kits and thought of combining them, but they are belt driven, and materials seem cheap to sustain the torque of a 2kW spindle and its weight without having too much intrinsic play...Let's keep in touch !!Best regards,Laurent
