Display & Chain Support (for CNC 2020)

thingiverse

Update 24.01.2019: Added support for X-Chain substitution. Supports for RepRap Full Graphics Smart Controller and cable chain X-axis, suitable for CNC Chinese 2020. I modified my CNC 2020 to use Arduino Mega, RAMPS 1.4, RepRap Full Graphic Smart Controller, and Marlin firmware specifically modified. To make the supports, you need: 1x Front container for GLCD smart controller (GLCD_Case-Front, recommended infill 20%); 1x Rear container for GLCD smart controller (GLCD_Case-Rear, recommended infill 20%); 4x Brackets or M3x25 round head screws for closing the container; 1x Chain support-hub (recommended infill 30%); 1x Support-hub for GLCD (recommended infill 30%); 2x Brackets or M4x25 round head screws for fixing hubs; 4x Round head M3x10 screws for fixing cable chain heads; 12x Holes for 3mm holes; 4x Holes for 4mm holes 22x Cable chain links, downloadable from the thing https://www.thingiverse.com/thing:11978 2x Cable chain heads, downloadable from the same thing as the cable chain links; 1x X-axis support chain (recommended infill 30%); Alternatively, as indicated in the notes below, print the version 2 of the X-axis chain support (CNC-SuppChainX(2)), with 30% infill and support. For assembly, it is recommended to use holes on both sides of the screw/bracket head. It should be noted that the LCD hubs do not allow freedom greater than 90°. N.B.: Verify that the cable chain does not jam in the X-axis carriage bearings. If this occurs, print and use the second support for the X-axis with a lower slider (file CNC-SuppChainX(2)). The modified Marlin firmware is available here (not my creation): https://www.youtube.com/redirect?q=https%3A%2F%2Fdrive.google.com%2Ffile%2Fd%2F1hFIoZKO6n8wDq_o3WB8wl6_FzaOIjbg4%2Fview&redir_token=v-6UFWNjuJrctgHPk97zMerj8XF8MTU0ODA5ODA3M0AxNTQ4MDExNjcz&v=jlOyqca9AqM&event=video_description The author of the modified firmware also posted a video showing its operation: https://www.youtube.com/watch?v=jlOyqca9AqM&feature=share Project files for FreeCAD are provided.
