Assembling your Hephaestos

Some tips from Dave, who recently assembled one blind from the instructions:

Additional tools needed. Screwdriver with removable heads, for Allen key heads (2mm and 2.5mm needed i believe) Also ‘helping hands’ for the soldering.

Chapter 1:

Fit the nuts: Do this. But whilst you have lots of plastic parts out, go through the ENTIRE model and find all the plastic parts. Then read all the manuals, and if there is a part that requires a smooth rod or other part to be passed through it, or any sliding interaction with another plastic piece, get a smooth rod and a file/sand paper and make sure that it goes through smoothly. This will save A LOT of time later on.

Preparation of motors. Flattening the motor spindles is not really necessary.

Preparation of the motor’s cables: Does not need to be done straight away. Would recommend doing this right at the end during wiring.

Chapter 5 - Fixing with flanges. I found the zip ties not to be necessary and the slot that the rod went in was secure enough and did not allow any movement.

Chapter 6. Section 4- Routing extruder cables……

Don’t thread the extruder motors cables first, do the hot end cable first, then the motor cable. Towards the end, they get quite tricky, use a small flat blade screwdriver to assist in pushing them through one by one.

Chapter 8- Routing and connecting the cables.

This is when i did my cable lengths. The guide lengths are good, but lead to a lot of excess on some extensions. If i was to make a second printer for myself, i would measure the length needed to go the neatest way into the motherboard using string, then i could cut the cables to the perfect length with no excess. But this would be purely a personal preference.

As you are soldering the connectors on to each motor, scratch into the connector which on it is (eg X, XL, XR, Y)
