Small PCB CNC V1.2 (Fully Printed Body)

thingiverse

Worked together with Moe_Fpv_Team to fix some issues with the mill. Hole accuracy was fixed and some little design changes were made. The two back parts which hold the board in place are now 3D printable. They should fit the case made by Hustensaft: https://www.thingiverse.com/thing:2609513 Furthermore we added some feet which should be printed in TPU with 3-4 perimeters and zero infill to get rid of some vibrations. We changed the 12x LM8UU 6x LM8LUU. Also we made the bed slightly bigger to fit 70x100 EURO copper PCBs. We used the Display-housing from the RS-CNC Project: https://www.thingiverse.com/thing:2159840 BOM: 3x Nema 17 Stepper https://www.banggood.com/custlink/333h9SGlvN 2x 8mm Smooth Rods 22cm https://www.banggood.com/custlink/m3GyISGlcv 2x 8mm Smooth Rods 18,5cm https://www.banggood.com/custlink/m3GyISGlcv 2x 8mm Smooth Rods 15cm https://www.banggood.com/custlink/m3GyISGlcv 6x LM8LUU Bearings https://de.banggood.com/LM8LUU-8mm-Long-Type-Linear-Motion-Ball-Bearing-Slide-Bushing-CNC-Part-p-994394.html 3x 608ZZ Bearing https://www.banggood.com/custlink/GvKyio6Z9O 3x Leadscrew (22cm, 18,5cm and 15cm) https://www.banggood.com/custlink/GvKhZ9GOdo 3x Coupler Lead to Nema https://www.banggood.com/custlink/vGGh8iDjYN Make sure to pick 5mm to 8mm bore! 4x M3 Spacer 20mm https://www.banggood.com/custlink/KmmdI9vLJT 4x M3 Spacer 15mm https://www.banggood.com/custlink/KmmdI9vLJT 4x M3x25mm Screw Arduino 3D Printer controller MKS GEN-L https://www.banggood.com/custlink/GmDRjpH797 Display (Optional) https://www.banggood.com/custlink/GvKdi9KjK2 12V Powersupply https://www.banggood.com/custlink/GDvyZSDapt 2x Fans https://www.banggood.com/custlink/DKmhISKLCg Spindle Motor https://www.banggood.com/custlink/KmvEiI3Omd This remix will be updated if something changes in the future.
