I’m curious if the limitation is motor HP to make cutting passes greater than 1/8" as recommended. Has anyone tried a 3/8" or 1/4" compression cutter and made one pass through 1/2" melamine? The only other setback I could think would be that the larger bit and stronger motor would put to much force on the floating cut head disrupting smooth cutting.
I guess you could put a stop in the code, and change from a downcut to a upcut to finish melamine cutting. but looking to see if you think it’s possible to avoid this step.
Motor HP is almost certainly not a limitation, many commercial CNC machines seem to use lower HP (and lower speeds) at faster feed rates. Frankly, much of the outside limits of testing hasn’t been done with MaslowCNC yet.
Here is a video of @bar running 1/4" bit at full speed (48"/min) at 1/4" per pass, and again at 3/4" depth. He speculates that a larger bit would perform better but that beyond 3x bit diameter you’d have problems pretty quickly, but in the middle there (using a 1/2" bit and similar depth setting) there’s probably some room to figure out a usable and accurate increase.
Obviously, for the different projects @bar has built so far, accuracy and repeatability has been key, and a good reason for using conservative numbers. On the outside edge of things I think folks have been busy getting their accuracy as high as possible and I expect we’ll learn more soon, as more and more MaslowCNCs come online and are reliably cutting accurately. It’s natural that people will begin to experiment more with where the outer limits are.
Bout 20 years back we might have bought one of those beds for Molly, Samantha, and the 2 or 3 custom dolls (can’t remember if we had them for all 3 girls). Just found a kid size Molly dress cleaning the cedar closet. Maybe it’ll go for a granddaughter some day.
All that AG paraphernalia adds up.
Must have more than 30 Barbies, bought Mattel stock around that time.
Allegedly people are paying $100 for a 2x4 cut up and screwed back together in extremely non creative manner all day long. If they are bonus. If not oh well I will still have a very hand tool. That I’ll suddenly have plenty of ideas of how to put to use.
No idea, 3 girls. Guessing the artillery is cheaper with boys, oldest girl got a nice 20g auto since the single shot left a big bruise from sporting clays. ER bills are probably more, think my parents got the quantity rate on stitches.
I don’t need more character
My daughter will be 10 next month and the hints of teenage turmoil are growing everyday. Though part of me hopes that’s just because mom refuses to let her live with me while the other part knows teenagers are teenagers. So I’m buckling in for the ride.
