Anycubic i3 Mega CNC Router Conversion

youmagine

I converted my Anycubic i3 Mega to a CNC milling and engraving machine. To accomplish this conversion, several items were necessary. Below is a list of modifications I applied to my machine: Dremel Mount (https://www.thingiverse.com/thing:3934942) A simple mount that slides into the universal mount. You can securely fit the end of the flexible shaft in this mount. X-axis Belt Mount (https://www.thingiverse.com/thing:3868324) This is a required modification for the universal mount to fit the X carriage. Universal X Carriage Mount (https://www.thingiverse.com/thing:3869322) This will allow you to mount the dremel mount to the X carriage of the machine. Y-axis Stepper Motor Cover (https://www.thingiverse.com/thing:3908207) A simple dust cover for the Y-axis stepper motor. Power Supply Dust Cover (https://www.thingiverse.com/thing:3908218) Another dust cover, this time for the ventilation holes of the power supply. 3D Printer Tube Frame Stand (https://www.thingiverse.com/thing:3867986) You'll need this as a base for the plexiglass enclosure. The parts for this enclosure are uploaded with this Thing, so you can find them under Thing Files. Mainboard Dust Cover (https://www.thingiverse.com/thing:3909536) The final dust cover, this time for the ventilation holes of the mainboard. Besides these modifications, I performed some additional changes: Removed all internal wires that were not necessary for the operation of the CNC machine. This means that things like bed heating wires, fan wires, etc. were all removed. Updated the firmware to allow for G2 and G3 commands, which is done with the #define CNC_WORKSPACE_PLANES line in the Configuration_adv.h file of the firmware (although I'm not sure that this was necessary in the end). Removed the entire extruder assembly Placed a plexiglass enclosure around the printer, the files for which are in the Thing Files. I used 2mm thick acrylic sheets. Mounted an MDF printbed, for which I printed some solid PLA spacers for the right height. Mounted an LED strip to create more light. Removed all the limit switches. These are not needed with the software I use (Estlcam). Remounted the filament sensor (the printer will give an error without it). Placed a 13x1mm aluminium rod within the plexiglass enclosure, that allows me to hang the rotary tool above the printer (this gives the flexible shaft enough room to flex). As you can see in the third image, this conversion works quite well. All three tools and the flexible shaft were included with the rotary tool I bought (https://bit.ly/32QcNcF). For software, I'm using Estlcam to create .gcode for the CNC machine. I'm importing .DXF files to Estlcam, which I made with SolidWorks. If you have Fusion 360, then you can also export your design to .DXF and then import it to Estlcam. If you have any questions about this conversion, please let me know in the comments.
