After figuring out that 3003 aluminum is not the best to machine (so much for that machinability rating speedy metals) I decided I didn’t want to wait for new plates so I used some fork terminals to wire the bed corners together buy slipping them between the washers and ninja flex corners. So No more chasing it around with an alligator clip!
Works pretty well so far. Need to figure out my first layer height and I have some z banding I need to track down.

Aluminum has to be cut very fast; it’s easy to machine but it has a tendency to gunk up on tooling if the speed isn’t fast enough or if the edge isn’t sharp. Ditto for other soft metals.
I have been having good luck with 0.001" per tooth on aluminum cutting lately.
Great to see the bed level system coming together.
Also I think we all keep tweezers around for that string from the prime sequence 
but you can build in a wipe sequence too that can basically eliminate that. I will hunt mine down from Talos and send it over.
Great job.
I have a wiper on it. Just haven’t gotten that far. That’s print #2 
I have solid numbers for 5052 and 6061. That 3003 was like cutting gummi bears of doom. I talked to some guys at work and they just chuckled. “If your not laser or water jetting or shearing that stuff doesn’t cut”
Awesome work @Joe_Spanier !
He speaks the truth about this soft aluminum. It reminds me of trying to shape bubble gum with a needle.
I was having issues and found a post on a machinist forum. “If 3000 series aluminum can make a professional machine at look like a newb, you can only imagine a hobby cutters final product”
Lol totally. I just brought the machine to my daughters kindergarten class and hit print. I made 1/4 of an elephant before the talk was done. Autolevel still the devil but damn its convenience.
