The 8.5"x21" control panel for my cnc is made presently out of 1/4" plywood and I will replace it with one made out of 1/8" aluminum. My cnc is made out of 1/2" thick aluminum plate, 3 axes, with 2 motors on the Y (A & Y)
I did a few trial cuts on MDF to assure that all dimensions / letters are ok and today I did the final cut
All square / round openings came out perfect but the letters which describe the function of each switch / pushbutton did not come out as my MDF sample.
For the engraving I used a 1/16" 60 degrees V carbide bid, feed rate was 10"/min, plunge rate was 5"/min and the spindle was set to 8000RPM. Used same settings on MDF and the letters were all perfect.
I used MastercamX5 and although its not perfect for engraving because you got to get the Art package, but it did a nice job on MDF and I was expecting to have the same results on aluminum.
Anyone has done engraving on aluminum to tell me what I did wrong?
