Dual Extruder Upgrade - Limited Availability

[Levi8than]

I had the same problem with the four retaining slots and the motor plugs cover. The wiring covers are tight but I got everything in. All I have left is the limit switch and firmware upload. Other than the tight fit of the wiring, the kit and instructions are well done. I have to admit the wiring does look good when finished.

Post some pictures if you can. Or a video of it running. I haven't seen any new posts since the leaked offset head pictures.

Just getting started on my upgrade, haven't started the wiring harness work yet. But here's a picture.

I'm done. Everything is heating but no fans are coming on. I expected the Rambo fan and extruder fan to come on but no go. Checked the extruder offset. Was returned as 31.1 so I think the marlin was loaded correctly

looking at your pic jin, whats the deal with the heaters? its hard to see but the hot ends dont appear to have the traditional block style ones. are they the regular heater cartridges and what are they mounted in to transfer the heat?

Check to see if you are connecting the fans to the correct wiring harness, only the original side is utilized for fans.

Fans are running and extruders are working. But the 2 nd extruder is turning the wrong direction. It pushes filiment during retract. Got to find out how to reverse that.

I think you've got the extruder stepper motor plugged into the RAMBo backwards.

jimc, they are short block heaters under the insulation, oriented vertically. I'd take a picture for you, but my cable is out and my phone needs to be docked for me to be on the internet. It is downright primitive, and Comcast is causing me to revert to a Hobbesian state of nature.

Word to the wise, there are two stepper motor openings on the RAMBo board, make sure you plug extruder 1 into the one closest to the rear of the machine. At first I plugged it into the first open spot I found which turned out to be related to the Z motor and then both Z and the extruder didn't work. Now it's better. Also looks like the extruder 1 motor needs to be plugged in backwards.
