Cutting a few more of the new Tria Delta plates. I am starting to find settings my @SMW3D R7 CNC really likes using a 1/8" single flute Kyocera Tycom upcut carbide endmills in 5052 aluminum.
Speed: 1150mm/min
DOC: 0.3mm
Spindle RPM: 24000
I had been breaking endmills in the past with slower-feed/slower-spindle/deeper-DOC. This particular endmill seems to like running faster and lighter instead.
I should mention “new” just means the new ones for me. I don’t want to presume these would become the defacto “new” ones in Alex’s main github. That’s for him to decide of course.
I also have had great success the last few days printing with these, and at high speed (120mm/s Atomic Filament Blue PETG) with no issues. So I will generate a pull request tonight to put them in a user mods folder for the Tria.
@raykholo yeah, the extra power is nice. But the 1.5kw water cooled spindle and 240v 1ph inverter I bought was overkill in hindsight. I am almost always profile cutting sheet stock with small endmills, not hogging with a huge endmills or anything. So the 800w version Brandon sells is likely the sweet spot if small OD endmills are going to be used.
