4" zip ties

Wire comb

Align the wire comb with the corresponding annotations (ie. filament fan, heat block, etc.), and secure it with a zip tie.

Goal: pre-install a 4" zip tie into every pair of holes that is 'connected' with an etching.

(Your etching may look more like a RECTANGLE rather than lines.)

That's 18 zip ties :-)

You should know that the record time to install all 18 (!) zip ties is under 3 minutes by Shawn and Stephanie from Baltimore.

Tip: It is more efficient to first drop all the zip ties in all the holes, and then pull them all back at once! Energize.

Tip: There are two groups of 3 holes around the middle that fit two zip ties - the middle hole is shared.

Acrylic Arduino spacer

Arduino + RAMPS combo (affectionately known as sandwich)

Put the arduino on top of the arduino spacer.

There are three holes that will align.

Attach the arduino with the arduino spacer to the inner back.

Gently tighten the screws to avoid damaging the board.

The holes are tapped so you do not need much force. You only need to hold it in place against gravity. No stresses here.

The Goal.

Disconnect the power supply connector from the rest of the power wire harness.

Remove the nut and spring washer from the connector.

Insert the connector into the frame from the outside.

Secure with the spring washer and the nut.

Remove one nut from the front of the power switch.

Place the switch into the "Big Friendly Button" hole from the inside.

Secure with the nut.

Commonly, switches are installed so that

bottom position = off

top position = on

Re-attach the positive terminal to the switch.

Re-connect the negative spade connector.

Minus MUST connect to minus and plus MUST connect to plus or you WILL destroy your board and will need to buy a replacement.

Read the wire labels. Red wire is always plus. Black wire is always minus.

You can find little pluses and minuses on the RAMPS board next to the connector.

Make sure to properly insert the power wires into the green RAMPS power connector, and tigten them very well. If you leave this connection loose, it may lead to excessive contact oxidation, excessive resistance, and eventually to a melted connector or fire.

The wire ends (crimps, ferrules) are thick; you need to fully open the connector.

fully open :-)

not fully open :-(

Tidy up with 4'' zip ties.

You can tighten these only lightly by hand.

USB extension cable

M3x12 bolts (2)

M3 serrated washers (2)

M3x12 screws and serrated washers

Commonly, USB connectors (type B) are installed facing upwards.

Yes, the USB cable is too long. Deal with it. Make a tidy loop and attach it to the inner back.

4'' zip tie

Small aluminum heat sinks (4)

Stepper drivers (4)

The drivers come pre-installed on the RAMPS board, you don't need to do anything.

Attach the heatsinks onto the black square chips on each driver.

The heatsink ribs should be vertical. This way the heat can escape upward more efficiently.

The heat sinks must not touch any of the contacts around the drivers. Or you may burn your drivers.

The heatsinks are optional but will increase the longevity of the printer. Drivers like to keep their cool.

Note: there was a limited edition of JellyBOX experimenting with 32 bit drivers; these do not require heat sinks. Thus, if you haven't got any heat sinks, do not despair and simply move on.
