Hello all, another newbie to cnc here, I'm currently doing some test runs on my cnc3020 using 4.5mm acrylic, I'm running with a feed rate of 700mmpm and spindle speed of 7000rpm, my overcut is set at 140%, I have it set to do multipasses of 0.4mm, I'm using 3.2mm Carbide Endmills, I'm pretty sure they are 2 flute, here's the url for them 10pcs 3 2mm Carbide End Mill Endmill Tungsten Steel Blade CNC PCB Engraving Bit | eBay , anyhow I've done a few test runs from 700mmpm to 1000mmpm, but the finish doesn't look too good, attached is a photo of what I'm getting. Any tips or suggestions would be great.
