Series 1, Slic3r and Marlin

If you haven't seen Slic3r already then go look at it: slic3r.org

And if you have a RAMPS based machine and haven't already switched to Marlin then get on that right now.

Its a fairly painless transition from Sprinter (apart from Marlin having an extruder lockout that stops it from extruding at 190C... simple to fix, but stupid in the world of PLA!). And once you have some acceleration values dialed in you can have your machine running quite happily with to speeds of 80mm/s printing and 200mm/s travel. And thats just my first attempt, I don't think theres any reason why I can't turn that top speed for printing up to 200mm/s as well....

Still need to fine tune my bridge settings.

Oh and the Series 1 prototype is looking rather good :)

Keep your powder dry.

Well, your filament actually.

Decided to use some white PLA I had laying around, turns out its sucked up so much water from the air its actually unusable. Not kidding, horrible blobby prints.

Ho hum, back to red, or one of the 3 or 4 other options!

Oh, and printing at 0.15mm layers!

Trying to run a 3D printer from a 3A 12v supply. Doesn't really work.

Big PSU on order.

Regardless of your views on copyright, it does exist and people can use the laws that surround it.

Which leaves me wondering, are the people who not only ignore blatant copyright violations but celebrate them and splash them all over their website, stupid or just cruising for a bruising? (as they said where I grew up).

It seems especially short sighted when its ripping off the IP of a company with a history of protecting said IP very vigorously.

The more things change the more they stay the same.

And now I'm at the fun part of the prototype... banging my head against the firmware barrier.

What I wouldn't give for a nice simple and well supported firmware for RAMPS.

Oo... Ultimaker firmware! That might work!

good thing/bad thing

Good thing:

Cutting a load of parts on the laser.

Bad thing:

Discovering all the bits that you designed wrong and don't fit.

More cutting.
Need a bigger and more powerful laser. Anyone got a 80+ watt 3'x4' laser I can use for free? (in the bay area!).

Post post post...

Lots of fun things in the post...

Lots of things cut on the Noisebridge laser...

Pile of stuff at Noisebridge waiting to be attached to the laser-cut stuff...

Maybe the Super Cupcake is finally going to turn into something more...

Watch this space.
