3030 CNC 3018 DIY Rude and Crude Remix

thingiverse

For those with eyes to see, a helping hand for those who don't. This is the 3030 Remix of shivackt's 3018 DIY CNC machine. You'll need: 2 x 3030 profile @ 390mm for X frame parts 2 x 3030 profile @ 320mm for Y frame parts 2 x 3030 profile @ 210mm for Z frame vertical parts 2/3 x 3030 profile @ 330mm for Z frame in between horizontal parts (I've removed one middle piece as 3030 is a sturdy frame, so you can also get away with only two pieces here) 2 x 400mm x 8mm smooth rods for the X axis 2 x 400mm x 8mm smooth rods for the Y axis 3 x 5mm to 8mm solid couplers 3 x 608 bearings for the ends of the leadscrews 3 x 8mm collars for the bearing ends of the leadscrews 2 x 400mm T8 leadscrews and leadnut (X and Y axes) 1 x 135mm T8 leadscrew and leadnut. (Z axis) 12 x 3030 inside corner brackets 1 x 300mm x 180mm x 15mm wooden baseboard 8 x M4 x 6mm Socket Head Screws to lock the smooth rods in place. 8 x M3 x 16mm Socket Head Screws to mount X and Y motors. 24 x M6 x 10mm Socket Head Screws to mount the plastic parts. 24 x M6 T-Nuts for 30 profile for the screws above. And a huge dose of patience - seriously. Of course, you may want to get all the other nice extras from shivackt (who I wish to thank for the 2020 version) but that's entirely up to you. The final versions here have been modified after I printed the original parts but they didn't fit well due to shrinkage. I've reprinted all the parts successfully at a 2.5 - 3% increase in size for ABS. UPDATE 14/10/2019 Just got my hands on a flexi extension piece for the Tork Craft rotary tool: http://www.torkcraft.com/index.php?route=product/product&path=818_1227_1228&product_id=17747 Added an Arduino CNC Shield V3.0 running grbl 1.1h firmware from https://github.com/gnea/grbl/releases/tag/v1.1h.20190825 Added: Spindle collar for flexi extension to fit into Z-carriage Clamps for rotary tool on rear of gantry to save space? UPDATE 7/11/2019 Added a new leadnut block for the Y-axis bed as the original was flimsy. Installed grbl 1.1 from git zip and it shows up as 1.1g in LaserGRBL. Set S32=0 for milling mode. Installed a4988 driver boards with trimpots at the bottom. Will be hooking up a 12V 300 W PSU to the GRBL Board and testing for correct operation. Will set the driver board currents to 1.2A. I am using 42BYGH4812AA stepper motors on all 3 axes. Still have to figure out the colour codes for the pairs as they are green, blue , red and yellow.
