The first task for my Solidis CNC was the EFIS panel. Here I could get some lessons about cutting and engraving. Especially the engraving was very exciting because when you want to engrave your panel after it is already cut out and painted, the engraving has to be exactly at the place it has to be. So I designed a touch plate which I cut out from aluminum to calculate the orientation of the panel to the axis of the CNC.
The panel was painted with RAL 7011, engraved and covered with some coats of clear varnish. I used 3mm acrylic glass from Plexiglas (white WN070 GT and clear 0A000 GT). The cut out was done with a 2mm single flute bit and the engraving with a 30° engraving tool. The cutting was done with 10mm/s and 0.4 mm of depth with each pass. The engraving depth was 0.2 mm.
Update: Because of the risk of breaking the 2mm cutting bit, I'm now using a 3mm bit for cutting operations and it is working good.
In the download package you will find the Estlcam files to cut out and engrave your own panel. As well as the dxf file to create your own tool pathes for your machine
