I used 400 speed. 80 % Max power and 20 % Min power. The file type I created them in is png.It seems to work better. The tile size is 9.75 inches wide and13.75 inches high. I used 1 bit dithering,Jarvis. Line quality was set at 20. I used the Rustoleum White 2x Extra coverage and let dry over night.The one I did on wood was on bamboo and stained walnut light, and added a coat of high gloss laquer. I sprayed laquer thiner on tile. Waited till paint shrivled up on tile,wiped clean and buffed with clean rag.
Big thanks to all who helped me get my Atomstack A5 M50 going !
