3018 CNC adjustable carriage

cults3d

A direct replacement 3018 size Z-carriage with easy adjsutment to either drop or raise motor. Uses regular OEM 45mm motor. Comes with a 20mm and a 10mm vertical offset motor mount and a carriage mount for stock 8mm guide rods and an upgrade for 10mm guide rods and the standard anti-backlash nut that used on most 3018 cnc's. This was designed to be used with the 3018 to 3040 upgrade kit and mounting the old 180mm y axis extrusions on top of the new 400mm extrusions to gain the extra ~32mm Z height while still being able to mill down to the bed without having to slide the motor down in the holder or extend the bit down further which makes you lose stability. And cutting old Y axis guide rods to make new Z axis guide rods (permanent Z carriage modification required use 10mm rods) or use as a direct replacement for stock motor holder with stock 8mm guide rods. Design allows you to lower motor 10/20mm or flip it over to gain an additional 10/20mm height. Also includes a 0mm motor holder. Uses a 1/4"x2.5" (m6x65mm) bolt or 1/4"(6mm) rod for lock. Will need either 8mm or 10mm linear bearings, available on Amazon and an 8mm acme thread anti-backlash assembly( can use stock one) or also available on Amazon. 8mm linear bearingshttps://www.amazon.com/gp/product/B087WPGQ8T/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&th=1 10mm linear bearingshttps://www.amazon.com/gp/product/B07H94RXPQ/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1 8mm Anti-backlash https://www.amazon.com/dp/B0936LS7HW/ref=sspa_dk_detail_6?psc=1&pd_rd_i=B0936LS7HW&pd_rd_w=hJQEy&pf_rd_p=0c758152-61cd-452f-97a6-17f070f654b8&pd_rd_wg=KqJQi&pf_rd_r=JH1Y65BHT5FTA6989DDX&pd_rd_r=69a4d1ca-385b-4732-82f9-03c6f2a8ab5c&s=industrial&spLa=ZW5jcnlwdGVkUXVhbGlmaWVyPUEyMUpLMEM1SDZKV0RLJmVuY3J5cHRlZElkPUEwNTc5Mzk0Mk1LNVhLT09CWlJLNSZlbmNyeXB0ZWRBZElkPUEwMzkwNTcwM0kxSVZaRUFETkFSRSZ3aWRnZXROYW1lPXNwX2RldGFpbCZhY3Rpb249Y2xpY2tSZWRpcmVjdCZkb05vdExvZ0NsaWNrPXRydWU= Update: adjusted some tolerances and chamfered some edges to aid assembly
