Got my extruders printed.:)  I attatched the STL that I used.  It is set up for 3mm filament, and 0.40 layer height.  The body is black and the gears are natural clear.  

Some of my problems with openscad where because I didn't have the files in the prusa repository source folder.  Apparently it uses settings from there.  

The way it's looking is the two nozzles are going to have a 3 inch offset from each other.  That's with them installed with the hinge forward.  I could rotate one and get a 2.5 inch offset, but I don't see any gain in that.  

Nate

That's awesome Nate, Thanks.

Looks slick haxar:)

It looks like the z axis is using the same setup for linear bearings as I will be using on my next one.  Does it come with rods, nuts and bolts?

The kit comes with everything necessary to build the Mendel.

Finally, here's a clean print of a 20x20 millimeter cube:

Awesome Haxar,

Have you done any calibrations so far?

Thanks Jeff,
I still have my heated bed video to put together and upload. :)

Nate

Good morning Nate, question, did you use the automotive heating pad for your heated print bed, if so what voltage is it and did you use a relay to control it ? I would like to find a heating pad that is 12 volts DC, or I think I might use nicrhome heat wire. Will you be working on your build today ? Have fun.

Yeah, I used 2 120VAC automotive pads.  I put together a box with a 30 amp 12 volt relay to control the pads.  Its been working great.  I'll try to get my video done this weekend. I finnished my ramps board in my hotel this week.:D  I might be printing a new ramps box design for the new printer today.  I'm also working on the O-ring pressure test print.  

Weekends have been very busy lateley. Lol

Hi Nate, good job on the heated bed plate :cool:. I'm working on my heated plate now, I'm going to drill a hole from the electronics side of the plate to the middle of the plate, then use heat paste when installing the thermister in the hole to the center of the plate, I think this will protect it and it will be able to since the temperature well.:D

I just got my new printer computer (AMD 3.3 Ghz 6 Core) put together and installed the latest Pronterface.  Looks like they did a lot of updating from my last install.  Not sure how much difference is from running on Ubuntu, which I think I'm going to like a lot.:)

Ha Nate that looks very nice, will it be able to run both hotends or do you have to tweak it :cool:.

Well I'm pretty sure I can't use pronterface for 2 hot ends.  I'll need to use RepRap Host, which I'm having all sorts of troubles with in Ubuntu.  It needs all sorts of Java programs installed, which I can't seem to do right.  I may have to start over again.  I also tried installing VMplayer to allow a windows installation to run inside Ubuntu, but of course that don't work either. lol(might want to stay away from ATI video cards)  I may be keeping the old Pentium III for the new printer for awhile.  Getting RepRap host to work on linux seems like a million hurdles to jump over, while Pronterface and SFact are a walk in the park.

Nate

OK so I still can't get RepRap Host to run on Ubuntu, and I need some j3d.org files that I can't download.  I stopped on over at the reprap IRC to ask where I can get them.  They insisted I not use Host, and use pronterface.  I said I need 2 extruders, and this is what I get for a reply lol:

[09:40] firepinto, don't get ahead of yourtself.  If you build it and it works mechanically, *I'll* write the firmware and adjusting PRonterface is easy
[09:40] Also, that's kind of a lousy approach, but whatever... go for it.
[09:40] lol alrighty then

Apart from my 2 extruder design being a lousy idea:rolleyes: sounds  like people could modify Pronterface to work with it.  All the (untested) designs I've seen for 2 extruders on a prusa have limitations because of lack of space in the printer.  This is where the KISS method kicks in for me, make more room on the printer.  So one could call it LOUSY lol but its SIMPLE.  :rolleyes::dodgy::rolleyes::dodgy::rolleyes:  I might have to look into makerbot software.:P

The only reason it could be a lousy idea is because they did not think of it first Nate, so it is a very good idea and one that should be pursued :cool:.

It's definitely going to be done.:P  I can still run Host on XP.  Even if RepRap host doesn't work well I'm still going to do test runs with it.  I'm just really surprised no one but Makerbot is pursuing the software and hardware end of dual extruders already.  RepRap host has the capability, but there is no dual extruder RepRap? :huh:So I'm sure there is a chance Host won't work.   I'll have to research to see if Makerbot software works with RAMPS.  I'm hoping I can put some sketchup hours in this week.  Its getting tough to do with out the printer frame and calipers sitting next to me. lol

The #reprap Freenode IRC channel users claim the "official" RepRap host software is outdated and obsolete and is only to be used in Bath, UK.

The developers for the alternative firmware and host software can't give support for dual extruders as they probably don't have such a setup.

Pronterface would take a major overhaul to run duals in my opinion.  Not that I'm a programmer, but it sure don't sound like an easy adjustment .  It can only load one STL to the bed plate as far as I know.    I find it kind of funny that a dual machine needs to be built before they try to develop for it.  RepRaps only give temp readings for feed back to the software, nothing to hard to simulate.  The second hot end could even be simulated with just a pointer on an existing printer for setting up offsets.  
To me it just felt like a Chevy vs. Ford type thing...

Here is a little sneak peek at the X end parts for my dual extruder printer.  I drew these up on my new computer with sketchup running in XP, which runs inside Ubuntu 11.10 Linux.:P  So far so good.   This machine has some horse power.:D

Tomorrow I'm attempting an X carraige for the extruders.

Very cool Nate, allot of time and thought went into that one :cool: .

[attachment=858][attachment=859]

More progress on the Dual extruder X axis parts.  I just need to draw up the belt clamps and tensioner, and then go through with a fine tooth comb to clean up the models.  I'll probably have to print one of each to find alignment problems and make some tweaks.  (unless I'm really lucky!) I'm not sure I like the X carraige but I had to start somewhere. :-)
