Robert,

Firmware for HD2x with modified E3D hotend is attached. Please be sure to connect everything to the RAMBo board verbatim if you plan to use this firmware.

For your reference, I have heard from several individuals who have successfully completed this upgrade.

Be aware that the hotend mount I have designed will only work with an E3D Volcano hotend. The volcano is 10mm longer (from the mount point to the tip) than the standard hotend. Another user has done a great job of modifying my design to fit a standard E3D mount, found here: http://www.thingiverse.com/thing:1698101 - It is the same design but with the mount 10mm closer to the build platform.

If you haven't found it already, here are step-by-step instructions for completing this upgrade, located on E3D's website: http://wiki.e3d-online.com/wiki/E3D-v6_ … HDx_/_HD2x

Let us know if you have any questions; good luck!

Gotta read some more but did you come up with an Arduino file for this new machine?

An Arduino file for what machine? I have one for the HD2x with E3D hotend, if that is what you're asking for.

i've reduced it to 2mm and also put a few drops of oil into the extruder- no more jams, hurray! However stringing is pretty nasty. Will try the coupling clip now. How much retraction are you guys using with your airwolf bowden+e3d ?

Re: Upgrading hotend: Airwolf HD2x to E3D V6 + Volcano

You should not use more than 2mm of retraction, E3D discusses this in their documentation.

http://wiki.e3d-online.com/wiki/E3D-v6_Troubleshooting

You're pulling hot material up into the cold part of the hotend, where it cools immediately and sticks to the walls of the hotness.

You should pull up on the collet as you push the tubing in. Doing this will lock it in the up position. If you don't like that approach, you can cut a credit card or print a plastic ring to hold the collet up.

You don't need much on an E3D. Direct drive I use 0.5mm for ABS and 0.8mm for PLA. While I don't have much experience with Bowden, you should start at these numbers and go up in increments of 0.5mm until you have enough. Maybe 2-3mm max. If you're pulling all the way up into the heatsink, you are using way, way, way too much. The goal is to relieve pressure, but you do not want the plastic to get into the cold zones.

The Bowden collet is in the "locked" position when it is pushed up. I've seen some people on here print a half circle to hold it in the upright position. If it's coming loose on you this may not be a bad idea to implement.

Guys, what retraction settings do you use? Namely Length, speed, acceleration? Both hotends are printing fine till they hit an area that needs some retraction, can't even print the hollow piramid torture test, it clogs big time the moment it hits the legs. And I mean it clogs so bad i have to disassemble hotend and burn it with a torch to be able to push filament through. It's not the nozzle, filament solidifies in the heatsink part. The heatsink is cool to touch, so I don't think it's heat creep, more like hot filament actually gets sucked in there and expands.

I'm currently using 6mm retract, is it excessive? I was using 7mm on the oryginal (buddaschnozzle?)
http://www.thingiverse.com/thing:29429

I also wonder if the minimum distance between retracts should be always higher then retract distance?

BTW do you have much play in the bowden couplinks? On retract/extrude I can see the tube move back and forth good 2mm on each side. I suspect if I stop this I can reduce my retract distance.

here's my hotend mount, what do you think? 1 piece holds on to the rails and small clamp secures the hotends to it. The rail clamp's got screws for regulating X tilt and getting the nozzles level (didn't have any small screws handy). Also added some extra screw holes for accessories, like the part fan or z probe. Currently for cooling the part I use 2 hoses with a powerful external radial fan (not in the picture, need redesign)

It worked!

summarizing, for those interested:
-i plugged in 5v and ground input of both thermocouples, in parallel, to pin 1 and 2 respectively, of the analog extension port.
-signal of thermocouple 1 plugged to pin 4
-signal of thermocouple 2 plugged to pin 6

edited pins.h:
#define TEMP_0_PIN 3
#define TEMP_1_PIN 4

I'll keep you posted on how my new hotends are doing.

thanks, will give it a try tonight. Also I will probably submit here my own hotend mount- rather then modify airwolf's i made one from skratch, so reduced the weight from 120 to 30 grams.

That's correct, power it in parallel.

Re: Upgrading hotend: Airwolf HD2x to E3D V6 + Volcano

2016-03-02T00:24:20Z

Thanks. And power/ground I can run from same pins in parallel with the first thermocouple?

Re: Upgrading hotend: Airwolf HD2x to E3D V6 + Volcano

2016-03-01T21:32:07Z

You can use any of the auxiliary pins for the second thermocouple. If you're using pin 7, I would use pin 5 right beside it.

I afraid I can't be of any help on the numbering. All I can say for sure is that pins 4 and 6 on the RAMBo board are assigned pins 3 and 4 in pins.h. Someone else might be able to shed more light on that than I can.

Re: Upgrading hotend: Airwolf HD2x to E3D V6 + Volcano

2016-03-01T04:07:36Z

thanks a lot, this is going to help! Yes, i'm using 2 thermocouple boards. I'm attaching my current setup for 1 thermocouple.

Counting from bottom left corner, I take power from pin1, ground is pin2 and signal pin 7 (however in pins.h it's called analog pin 8).

Would it be possible for you to specify exactly where to wire second thermocouple? And what analog pin nr to specify in pins.h?

thanks again
