Everything is working great but I have noticed a lot of stringing. I have cranked up the retraction settings because of it but am still noticing a lot of it. Anybody know anything?

Sketchup isn't perfect for 3D modelling but quite easy to learn or either tinkercad which is online tool and dead simple, tinkercad also provide some basic tutorial when you sign in for the 1st time. There are loads more but in my experience the easiest are those two.

My plan is a bit different I'm going to use all my electronics from a printrbot simple!
My question is, as I know the square root of jack sh*t about 3d modelling, if at all possible could someone create a mount for the ubis hotend in the same fashion as the e3d one with a Bowden clip just above? I found this http://www.thingiverse.com/thing:693196 for sizing. If not no worries at all, I have this http://www.thingiverse.com/thing:731848 converter as a work around.

Also RAMPS upgrade is very easy thanks to the @Anthem. All depends how neat you want it.
My upgrade took literally a bit under an hour! BUT it's far from being neat by ant stretch. I haven't wired up Jr endstops (ziptied microswitch endstops instead), haven't removed logic board or any Jr part - just unplugged steppers and ran long cables to the side where my RAMPS, PSU etc are. Did it just as a test but never had a chance to do it properly! wink

If you have any questions about converting feel free to ask.

@Anthem. Ive read your tutorial several times. excellent writeup btw. Ramps is the way im gonna go. I will have questions but of course, my main worry is he manual bit. lol. Plenty patience and no time limit. Time to let my JR spread its wings!

When you mentioned "new type of the thermistors" are you refering to this http://e3d-online.com/E3D-v6/Spares/The … -Cartridge?

Also I can confirm that I had one of those new type of the thermistors but as far as I know old one was exactly the same, or pretty much very close to the new one.

Also 20-24c as @Kronikabuse said looks like room temperature to me.
1. If you try to warm up the thermistor by simply holding it in your hand does temperature goes up to 30c+?! (obviously standby mode otherwise you'll burn your fingers off)
2. Is cartridge heating up?! If you month have external thermometer use wet paper towel or piece of filament to determine if it's heating up.
3. Do you have multimeter?! Try to measure resistance on thermistor and heater block. Thermistor should be around 100k obviously and heather cartridge should read +/-3.5ohm if my math is correct assuming it's 40w cartridge.

And yes you are correct, fan requires right polarity but thermistor and heater block does not.
Also at least with my Jr when thermistor isn't plugged in it reads 10c, so if that's the case with all Jr then it reads something.

And the last as suggested by @Anthem - if you have enough spare time and love tinkering with electronics as such - go with the RAMPS upgrade. Money wise it's the same as couple of pints. The other day I've ordered another RAMPS + Mega + 4x A4988 of Ali Express, less then £15 delivered. If you want LCD that will be extra £6-7 (I've stopped wasting money on LCD's - I find them quite useless to be honest)

I may have misunderstood Kr15_UK 's post. I thought the E3d 100k thermistor would work oob but it seems not. I may, with a lot of help from a friend, attempt the Ramps conversion by Anthem. That will give me much more control over this printer.

Well, this is a pain. I've wired up the E3d. E3d Fan has correct polarity. Using E3d's 100k NTC thermistor. I believe polarity is irrelevant. Same as E3d 12v heater cartridge. When i try to run a print the temp reading on the display switches between 20 to 24c constantly. It does not go any higher. Wiring problem? I'm quite confident that the wiring is fine. Any thoughts?
btw. I'm using printers stock fw.

What is your MIN_TEMP set at in your firmware? Have you used a host like Repetier and checked the log to see if there are any errors?

I believe even on the davincis you need to flash the firmware for the new thermistor tables. If the firmware is right check the wiring

You'll need all three .scad files to render the brackets. I'm still not 100% certain I'm keeping this design (I have several ideas for a V2), but until I actually get some test prints out of it I won't know for sure.

Just flip the booleans at the bottom of the dual_hotend_bracket.scad file to pick the model(s) you want to render.

After my first print last night I've made some other adjustments, though.

For one, I realized that the bolt holes were way too long. I only have M3x20mm bolts at my disposal, and the holes were way too deep for those. I've switched back to using screw-in holes for the clips that are the right size to accept an M3 pretty well. I'm also testing a different approach for dropping in the M3 nuts for the DVJr hotend mount spacers.

Also, I figured out I was able to cut out about 13mm of dead space between the two hotends, not only reducing their offset but allowing me to shrink the width of the entire thing.

After these modifications, both hotends should be able to reach X=0. The right hotend can reach the full X axis, and the left hotend can reach all but about the last 8mm of the X-axis.

If I redesigned the DVJr fan shroud and my mounting method, I could get rid of the metal mounting bracket entirely, which would probably make up that difference and let both hotends reach the full X-axis.

Good example was with my cooling fan solution, if I used regular thickness 40mm fans they'll hit left hand side and prevent Jr from homing properly. Also by doing dual hotend setup you'll lose even more printable area on X axis. Actually if you are planning to extend Y axis you could hack both hotness in line so you don't lose on X axis print area but I guess there's a reason why no-one does that...
