E3D Upgrade from Kicksatarter version

Well, finally getting around to upgrading my kickstarter Gen 1 printer hotend to an E3D v6. Got a few questions hoping the community can help me with. Ok, well, I figured out some stuff.

1. I figured out the fan on the E3D needs to be running all times so I have to wire it into the 12v. Does someone have a diagram of the board for the 1st gen robo3d showing where the 12v is?

2. The heating element for the E3D comes with a pretty long cord that looks extra insulated. Do I have to use that cord instead of the prewired wires or can I clip the wires on the E3D heater short and wire that into the pre-existing wires? Main thing is one of the wires hooked up to the default robo3d heater is yellow but I see no yellow wire coming out of the wire bundle under the printer so I am not sure where the heater pins are on the RAMPS.

 

1)

2) The E3D cartridge heater is higher amps so you probably shouldn't use the existing wiring. Unless it's of sufficient gauge which the first gen's weren't. Unforunately though the stock wires are about 150mm too short to reach the board sufficiently

In the picture you posted, the 4 screws for power and ground, aren't both outside power and both inside ground? Or did this change after the kickstarter version. I only ask because I also have this version that I got unopened just last week and want to do some upgrades.

Why do you think outside is + and inside is -? It should be in pairs like Mike shows.

 

Because that is what my voltmeter says and the wire coloring matches. But regardless...my question now is does anyone have an issue with the nozzle not being level when installed?

With the "clip" installed on the top on the nozzle it is sits in a tilt to the side. But without the "clip" it's loose.

 

What do you mean level? What clip? If you mean the stock metal fan holder, it won't fit with a e3d

 

I will take some pictures when I get home. The ones I did take were rushed and sloppy. But the "clip" I an referring to holds the tube in place if you are running a bowden setup.

The black piece above the heat sink around the tube



If I remove it, it is loose. If I leave it in, the nozzle is on a small but noticeable tilt and still has some play.

 

Drill out the gregs wade extruder, feed the PTFE tube up to the hobbed bolt and into the E3D as designed

Drill out a little extra to fit the compression coupling.

 

So modify the stock part the extruder mounts into?

 

Yup, running the PTFE will be very helpful, especially with flexible filaments

 

I use the tube above the feeder just so I don't loose it. But good to go. Thanks for the tips

 

The photo of the tilt I was referring to just for grins right now.

Tilted


Almost straight



Like an 1/8th inch of deviation or so

 

Make sure it's straight before you thread in the screws

 

It is, but moves as I thread them. I'm going to modify the housing like you said before and that should fix it.

 

what is your parts fan on?

 

The original fan is on a new printed bracket

 

I think it might be because the screws don't go all the way across. I moved one to the opposite side in a stagger and it's level now.

 

JIC you haven't wired yet -- I just did this upgrade over the weekend. I just reused the wiring that is already running up to the original hotend. No mods were made to the original heater, just removed and installed in the E3D, cut the wire to the original heatsink fan and used the supplied heatshrink and crimps for this, and then thermistor was handled the same way, installed new thermistor and crimped/heatshrinked the connections to the old ones. Makes for a far less involved install and you get to use the original quik connects...
