3018 CNC upgrades with SKR Mini E3 V3.0 running Marlin 2.0 controllable with Raspberry Pi
Description
This is a remix from Teaching Tech’s Sainsmart Genmitsu 3018 CNC upgrades https://www.thingiverse.com/thing:4740697 https://www.youtube.com/watch?v=Q4TrzshXV10 The main goal is to replace the original GRBL board with a controllable marlin board. Here are the differences from his original design - My 3018 CNC machine uses 2020 aluminum extrusion instead of an acrylic frame. - Using SKR Mini E3 V3 instead of discontinued SKR Mini V1.1 - To incorporate this new board, I updated the firmware to Marlin bugfix-2.0.x - Since I’m waiting for a working LCD, so I will have to use raspberry pi 3b to control the device. - Using the original motor provided by the original kit. - Using FAN1 as Spindle enable pin. And supply 5V and GND from Filament stop pins. Using locally sourced single channel relay. Tested working with original 24v spindle motor. Shopping list - SKR Mini E3 v3.0 https://s.click.aliexpress.com/e/_DmjuX4F - 5V Single Channel Low-Level Relay https://s.click.aliexpress.com/e/_DENxkkP This is an unfinished project and it’s highly bare-bones. Please be extra careful when working with the main voltage.
