Hi guys! Just needed to share, couse felt a little success moment today.
Not anything too special but...
It has been a deeeeeep learning curve last 3 months. Made some chips and broke some bits

Have tried different materials: wood, ply, pom,acrylic,alu. Its been great - lot of learning

So today I did aluminium. 2d adaptive, 6mm doc, 14300rpm, 785mm/min, 2flute carbide endmill, z fully extended, wd40. Best sound so far for alu! Honestly...it was quiet! I constantly thought that something is wrong and will screw up.
Finishing pass + chamfer. Though chamfer was a little bit disapoitment in radius section.
Did not wanted to make a video. Since few years back I promised myself that I will never going to manually apply wd40 and compressair, or hold a vaccuum hose next to spindle

That is definitely a great success. The cut looks very nice. Chamfer also needs a finishing pass. Same like normal side milling. I am almost sure you did not do that? So no real reason of disappointment. 0.05mm or 0.1mm will do the job next time. Also workpiece needs to be tightened to bed very strong.

You are correct, I did not do it. Lesson learned again. Thanks Boyan!
