E3D V6

[jimc]

for any of you guys in the past who have or are using my e3d mount and drive duct on thingiverse....i made a change. go on there and download the new bed cooling duct and print it. i made a couple tweaks to it so it sits centered on the heater block and gives a little more room for wires.

the firmware on the wiki is the correct firmware and is what would be on your machine right now. just pick the right one that applies. i think there are 4 different ones for different versions of the m2. the firmware change is easy. all you need to do is in the config h file is change the thermistor table to #5 so the temp reads correctly.

Well that seems simple enough. I take it that change needs to be made regardless of the 12v or 24v version? I'll put the order in tonight and print out the new and improved version of your drive / fan mount.

It never ceases to amaze me that you can print upgrades to a machine that you are upgrading etc etc.

[jimc]

yes. the difference is that makergear and e3d use different thermistors so to read accurately they use a different table. its already built into marlin. you just need to set it to read the right one. goto the arduino website and download the software. you will open the firmware up with that program, make the changes then upload it to the rambo.

Thanks Jim, this makes it perfect. The wires were my only issue with it and not a big issue at that as its been working great!

[jimc]

yeah it always worked but was just one of those things i know could be improved. just never got around to it. now that i have 2 m2's here i figured i would do it. i didnt want to print another round of hardware with the old style duct.

Ok guys so my 24v version of the E3d arrived and after cannibalizing a molex connectors from my spares I have the thermistor and the heat element installed (I reused a spare one of those as well, keeping the one that shipped with the E3d as a spare).

After doing all this 2 things struck me

1) Why the hell did I bother ordering the 24 volt version when I just reused all the 24 parts from my spares
2) The 30mm fan that shipped with the kits was also 24v and that is different from the 40mm 12v version that blows on the standard v3b hotend.

Do I need order a 12v version of the 30mm fan?

[jimc]

yep you should have just ordered the 12v version. you can take the cartridge heater right out of the v3b and put it in the new hot end, you need a 12v 30mm fan now.

Yeah . It didn't cost any more for the 24v version but got a new 30mm on the way.Oh well it will give me time to get all the mounting stuff printed.

Jim on another note it seems to be that your filament drive perfectly lends itself to other attachments in addition to the fan shroud. My thought its it would be a great way to mount a machinists meter for easy bed leveling. Any chance you could provide the original design files. If not its fine I will bust out my limited modelling skills and a set of calipers

[jimc]

Actually i have the snap on bracket as a seperate model so you can make what you want then just add the bracket to it, print it them it should snap right into place. I can guve ut to you in the original 3dm file for rhino or a step or iges.
