Pretty new to this but I have been machining Acrylic on converted Sieg X1 mill between 1500 -2000 rpm DOC 1mm FR 1200mm/min 6mm 2 flute and getting good results for welding with Dichloromethane faster RPM than this I was starting to have problems with heat softening the Acrylic as cutting without any cooling. I set it running in Mach 3 and adjusted on the fly for first couple of cuts testing the limits, then went with it. 2 flute performed better than 4 flute for me.

Thank you guys for your replies !

Today I took my first cuts and the machine is currently slotting the sploiboard :) Running at 10000 RPM and a FR of 950mm/min. Chips are perfect, and there is a little bit of smoke when the bit does its first pass because of the MDF surface. Otherwise, it's looking great ! I will have to sand it a little bit when i'm done. So far, the slots are being cut. Second operation is the T slotting. I'll post pictures when I'm done. I had to cheat a little bit for the GCode in Masterdom because I had to draw the part bigger than what it really is so I could make pockets for the slots.

I also went to the store and bought a dry/wet vacuum cleaner, because things are getting messy haha. Gotta make that dust shoe when I get my 3d printer !
