Had originally bought the parts for an MPCNC almost 2 years ago. I was sold on the design as soon as I saw how some smart ass designed a working cnc machine out of roller skate bearings and emt conduit. Always thought 3D printing was out of reach but yet this machine could work as a printer too and make itself on a budget. It was an inexpensive entry into CNC and 3D printing that I couldn’t resist. Thanks Ryan for the machine and fostering a community around it.
The machine doubled as a printer and router and help build a MP3DP. The original build of the MPCNC was with too small of a foot print for many things that I wanted to try. The time come to resize it this summer. When disassembling noticed a few parts had cracked from over tightening and time. Would need to replace some of the corner pieces so started printing burly corners… but I got side tracked in Tinkercad.
When building and rebuilding the MPCNC I always wished I could use a sheet of peg board to square up the machines corner to corner. The pegboard is squarer than I can measure with my trusted measuring tape. Why not make the sides out of peg board and take aligning the height of the legs out and square them up too. The corner supports of the MPCNC could be part of a peg board box used to align and strengthen the machine.
This is my first designed project with 3d printing so the pieces are crude and will likely break but that is no reason not to build it.
Finally finished printing enough pieces this long weekend for the pegboard enabled corner posts. The assembly process starts from the top (flipped upside down). Basically temporarily use a sheet of peg board affixed to the top pieces to align the corner posts during assembly of the box and mounting to the table at which point the project is flipped over and the top board removed to continue with the adding the real MPCNC guts.
It begins. Shown is the original MPCNC corner parts side by side with the equivalent Pegboard Enabled Corner Posts elements and a mock up to show how it is hopefully going to engage with the peg board during assembly.
A picture of the first stage of assembly was added.
