MendelMax
« on: April 23, 2013, 07:48:15 PM »
Hey guys. I'm still alive. (lol)

I've brought BreepBroop home to spend more time printing parts for a MendelMax. Perhaps work on BreepBroop and make it a tad more reliable while I'm at it, though it's just been a damn champ since it's been at the house. Printed prolly 24h total and is still going; only one minor snag hit.

I'll post some more info as I figure it out and work out what's happening with it, the long and the short is that we'll for sure be making it bigger than a normal MendelMax; the current dimensions for the bed will be 20"x16" or so, and it should be able to print to the edges. Dual extrusion is pretty much a given on it as well. Hopefully I can get it running well enough to leave at the lab. It's going to be built like a damn tank.

Suggestions on colors? The extrusion will be black, which looks awesome with brightly colored printed parts. Examples:

I think the neon blue looks pretty sweet. Tron style. And that is one way sweet 3d printer. :D
yes.

I vote neon blue. Ben's right, with a few of those UV Leds or one of those UV LED panels, we've got a tron-style printer.
I like colors.

With the extrusions, I could load the channels up with blue EL wire :D

Well, I ordered the Misumi extrusion and hardware, and the rest of the frame hardware from McMaster. That should all be here early next week. Going to start working on the issues of leadscrew and linear motion for the Y axis.

UPDATE!

The frame is built.



Also, I devised a little tub to hold my PLA and keep it nice and dry. Perhaps someone would like to use a similar thing for Nylon? Keeps things around 20% RH inside...

Got my MetalMagma hotend in as well, it's pretty!

I may have the whole mess at the lab tonight, depending on if I am able to transport the frame.

I have swapped all the rods out for some thicker ones, 16mm on the bottom and 1/2" on the top, cause of flex over the huge spans. I don't have pix yet, but building some belt clamps this weekend, helping a coworker build his Lulzbot TAZ, and trying to crash the new quadcopter.

More infos on this:

  • The power supply driving the Y axis motor is 80VDC at 16.5A. That's 1500W of power to drive a single axis! Yowza!
  • I have done countless edits to "parametric" SCAD files from thingiverse to fix ones that just degrade into a hot mess when you make a few numbers bigger.
  • The new rods are hueg like xbox, and are super thick. Using some bigass pillow block bearings to keep the Y axis stable. Also, not using any sort of springs on the bed, it's too heavy. Will be fixing it solidly in place with spacers (small washers and perhaps paper to exactify the level)
  • The bed alone (Aluminum and tempered glass plate) weighs in at 10lbs!
  • This has been designed for dual-extrusion from the start, and the head should be able to carry two extruders around, but don't expect speed out of this one.


Here's more pix because pix.

Here's more pix. As it stands now...

Since the last pics, i've bulked up those rods, drilled the holes for the belt to run the Y axis, printed the mount for the large motor, installed the carriage, and am getting ready to start wiring things in.
