Here is the firmware: https://www.dropbox.com/s/6t4sm836w2xwab...n.rar?dl=0

Everything in this firmware is set up to use with a delta. Hope this helps you guys. I ordered a new hotend but is is from China, I ordered it because it was only about $10, this one I will not screw up (hopefully) but I'd also be willing to print out some of the parts you need for the printer if someone supplied the filament.

Thanks! I'll check the firmware out. On the RepRapWiki the Rostock firmware is said to have lots of upgrades in it, but I'll have to compare them. Either is going to take custom config.

$10 hotend would scare me just a little bit. The JHead I ordered is obviously a Chinese clone at $35, but they seem to have a decent reputation if setup right. I'd love to grab another Hexagon or a E3Dv6 as they handle nearly every material because they're all-metal, but those are on the pricey side. Maybe once it's running and needs an upgrade (unless we decide we need a Chimera, or even a Kraken! Big Grin

).

Thanks for the offer to help! What's yours run? 1.75mm? Will it do PLA and ABS? I've got a fair amount of both in my filament chest. Not sure what frame we're going for yet as we've got to see what we've got in parts (linear bearings and the like) laying around. It might end up being completely custom to utilize available parts and keep cost down (yay 3D printing!).

I will bring my 4 - 4' linear rods and bearings tomorrow

I was waiting to evaluate materials on-hand. Part of the problem is the frame rails need some way to prevent twisting, so we can't just toss a single rod on each corner. Though, combining the linear rods and bearings you have as a drive rail, with the 3/4" aluminum rods at the space as a bracing rail, we could make a 4' tall frame. With the 18" traxxis rods I saw online, that's roughly a 14-16" diameter build envelope. We'd never have time to print something that large (max volume would be something like 14" x 36" and take days to print). Unless we doubled up on the belting or went with threaded rods, there would probably be a fair amount of stretch over 8' of belt at each corner.
