The 18+" aluminum disk came in today. A 34+ lb lump of aluminum is ... heavy. [www.ebay.com] The surface finish is quite good. There's a bit of dirt and a minor scratch here and there. The streaks in...

Funkymonk, Does it straddle the top inside the triangle? The end result being filament management similar to the original 3DR?

@uncle_bob: If you want a mirror finish on your aluminum Flitz Metal Polish is probably all you need. I would begin and end using a wax, and grease remover. Flitz Industrial Strength Aluminum...

At this point I'm not to concerned about mirror finish as much as I'm concerned about keeping the surface flat. I'll probably keep it in the packaging until I'm ready to mount it and give it a good...

Alcoa Mic-6 looks like a very stable metal at high temperatures. Are you planning on printing directly onto the aluminum plate? How flat of a surface do you require? You could use a lapping plate to...

Actually I think this one better if you want Johann's probe code and M66 end stop offsets. [github.com] I myself don't use the probe so I'm using the main Marlin branch with the delta configuration...
View ArticleRe: Current best version of Marlin for a 3DR or 3DR Simple?
The only differences I have found are that Erik's Marlin firmware [github.com] uses bed leveling in a square pattern, and Johann's [github.com] uses bed leveling in a more circular pattern (or so I've...

Flatness: A lot depends on how thin a first layer you are trying to print. If I stick with something in the 0.2 to 0.3 mm thick first layer, a flatness of 0.02 mm (slightly under .001") would be...

Sorry to backtrack a bit, I just finished making my delta printer, and I'm itching to make a lead screw LISA. I read through this thread but maybe I missed it. I know you guys were looking into ways...

@vinhdinh: I'm pretty sure Nicholas Seward has mentioned mounting the motors on top. Good idea, and there no reason you couldn't mount the stepper motors on top of the upper platen, and out side of...

1) If you put the motors on top, you need something to terminate the short lead screws into. 2) Most of the torque and force is on the plate that has the motors and screws in common. That would mean a...

Now that I understand how the sexupteron operates; I'm awestruck nicholas. Truly. An ingenious design. Any news on progress?

There's never a design path that's all good or all bad. The cost of the lead screws (with some thread designs) is fairly high. That can drive you to a compromise that shortens the screws. In my case...

Why not just use the rod jig JohnSL made for his 3DR simple? Mounts right to the printer.
