MGM 12 Linear guide part for CNC3018 Pro

thingiverse

On my CNC3018Pro, the existing linear guide is often too unstable to machine harder materials (hardwood, brass or even front sheets 1.5- 2mm deep).For this I bought a more stable Z-axis for my CNC 3018Pro. The conversion was not difficult, now it showed that the X-axis also needed a more stable linear guide.A simple solution was needed.First I replaced the 20x20 aluminum profiles with 20x40 and one 20x60 profiles at the back of the CNC3018Pro.And added a linear guide as shown in the CAD drawing (in the CAD drawing there are, still, 2 pieces of 20x40 aluminum profiles).As shown in Fig. 1, an MGN12 linear guide is mounted at the upper position of the 20x40 aluminum profile. Make sure that the MGN12 linear guide is well aligned, as the Z-axis is now equipped with 3 linear guides. A bad alignment of the linear guide would worsen or even block the movements of the X-axis.A mechanical connection is now missing between the additional linear guide and the Z-axis module. Which I have designed as in 3D as it is to be seen in the picture 2. This 3D design was designed by me with DesignSparks mechanical and has been uploaded as STEP here.As usual, so that everyone has the opportunity to pick up the idea to adapt his CNC 3018 or derivatives as desired.I recently upload Step-files with the STL files. STL-Files can often not be well adapted and if then it costs unnecessary time.The MGN12 trolley needs 4pcs M3x10 screws,the 3D model has the correct drilling dimensions for fastening.Only the files provided here for download are made available. I ask you to refrain from requesting files that can be seen in the pictures.(All texts are translated with DeepL.)
