Dremel CNC

Support my future designs and developments at https://www.patreon.com/BangEnterprisesA simple CNC setup using old 3D printer parts, and a Dremel with flex shaft extension I had lying around. My design goal was basically to use as little plastic as possible, while still having the machine structurally sound. This will probably always be considered a work in progress.The dremel attachment is meant for one of the old dremel specific flex shaft extension. I made the attachment point somewhat modular, so you can attach a different end effector, if you choose.I have attempted to build several 3D printers, so I have a lot of extra parts hanging around. I just designed the CNC to use those parts.I originally used IGUS plastic linear guides, but I switched to linear bearings, because they were not that expensive, but significantly higher quality. The mount for them can fit either.T8 lead screws:https://www.amazon.com/Copper-Coupler-Hexagon-Bearing-Printer/dp/B07S1LKMQ6/ref=pd_ci_mcx_di_int_sccai_cn_d_sccl_3_1/137-6398462-3114451?pd_rd_w=ex2KY&content-id=amzn1.sym.751acc83-5c05-42d0-a15e-303622651e1e&pf_rd_p=751acc83-5c05-42d0-a15e-303622651e1e&pf_rd_r=CH3M84FD11REXAAWAFQA&pd_rd_wg=xQGk2&pd_rd_r=e2873a89-a0f0-423b-8b13-5eac999874a1&pd_rd_i=B07S1LKMQ6&psc=1T8 anti-backlash nuts:https://www.amazon.com/gp/product/B07T3Q4VK7/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&th=18mm Linear Rods:https://www.amazon.com/Linear-Motion-Printer-Machine-Diameter/dp/B0BL75SXMD/ref=sr_1_6?crid=3L9CYI4YVD3LS&keywords=8mm%2Blinear%2Brod%2B300mm&qid=1707158729&sprefix=8mm%2Blinear%2Brod%2B300mm%2Caps%2C93&sr=8-6&th=18mm IGUS:https://www.amazon.com/gp/product/B07B3PZ7JH/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=18mm linear bearings:https://www.amazon.com/LM8UU-Linear-Bearings-Length-Printer/dp/B087WPGQ8T/ref=pd_bxgy_d_sccl_1/137-6398462-3114451?pd_rd_w=DVu1B&content-id=amzn1.sym.839d7715-b862-4989-8f65-c6f9502d15f9&pf_rd_p=839d7715-b862-4989-8f65-c6f9502d15f9&pf_rd_r=JW7ENMW3AM135G3912DK&pd_rd_wg=tt2LN&pd_rd_r=2781c0ae-d8f1-4faa-8494-58afd6249bf6&pd_rd_i=B087WPGQ8T&psc=1Electronics:https://www.amazon.com/Twotrees-Printer-Controller-ArduinoIDE-Stepper/dp/B096RZYJG5/ref=sr_1_4?crid=FFHFU465LKW4&keywords=grbl%2Bcnc%2Bcontroller%2Bshield&qid=1707158904&sprefix=grbl%2Bcnc%2Bcontroller%2Bshield%2Caps%2C78&sr=8-4&th=1
