This is a customizable riser for an FFC (flexible flat cable) extension PCB.

This riser is intended for use on a Sidewinder X1 with either:

• the stock extruder assembly
• an aftermarket extruder assembly (such as the E3D Hemera).

Please note that when you use this riser on a Sidewinder X1, you will no longer be able to use the stock breakout board cover.

This design is completely free and shared under a permissive license. Your support is hugely appreciated.

Purpose

The riser serves two potential functions:

1. Flexible flat cable height adjustment

Firstly, it can be used to raise the height of the FFC connector to prevent the flexible flat cable from rubbing against the X axis pulley wheel. In particular, when fitting aftermarket extruders such as the E3D Hemera, the position of the FFC can be lowered (depending on how it is mounted). This riser can be used to raise the height of the FFC connector via an FFC extension PCB.

2. Securing flexible flat cable connection

Secondly, it can help prevent the flexible flat cable from becoming loose. The FFC connectors on the breakout board of later versions of the Sidewinder X1 (such as the V4) do not have clips. As a result the flexible flat cable can work itself loose over time. A number of supports exist to help prevent this, however some FFC extension PCBs have connectors with clips. Using such FFC extension PCB with clips will help to secure the flexible flat cable.

STLs

A few pre-configured STLs are included that have been rotated for printing (`Rotate_For_Printing` option enabled):

• `codeandmake.com_Sidewinder_X1_FFC_Riser_v1.0_E3D_Hemera_(parallel).stl` - This is an export of the default settings. This should be ideal for an E3D Hemera extruder assembly (using the recommended or similar printed mount). **This has not been tested - please share your makes and comments**.
• `codeandmake.com_Sidewinder_X1_FFC_Riser_v1.0_E3D_Hemera_(perpendicular).stl` - This is an export with the the `Inner_Cable_Slot_Offset` value set to '0' and the `Parallel_PCB_Mount` and `Outer_Cable_Slot` options disabled. This should be ideal for an E3D Hemera extruder assembly (using the recommended or similar printed mount).
• `codeandmake.com_Sidewinder_X1_FFC_Riser_v1.0_Stock_(parallel).stl` - This is an export with the `PCB_Mount_Vertical_Offset` value set to '0'. This should be ideal for the stock extruder assembly. **This has not been tested - please share your makes and comments**.
• `codeandmake.com_Sidewinder_X1_FFC_Riser_v1.0_Stock_(perpendicular).stl` - This is an export with the `PCB_Mount_Vertical_Offset` and `Inner_Cable_Slot_Offset` values set to '0' and the `Parallel_PCB_Mount` and `Outer_Cable_Slot` options disabled. This should be ideal for the stock extruder assembly. **This has not been tested - please share your makes and comments**.

You will need
-------------

For fitting to a Sidewinder X1 you will need:

• 2x M3 screws (see note below)
• Up to 2x M3 nuts (square or regular) - This depends on how your breakout board is mounted
• 1x 20 pin, 1mm pitch FFC extension PCB
• 1x 20 pin, 1mm pitch FFC cable with same-side connections (ideally about 10cm - the one pictured is 15cm which is sligtly too long)
• A cable tie
• Some double-sided tape or a sticky foam pad (optional)

A note on screws
To attach this riser you will probably need slightly longer M3 screws than the ones currently being used to mount the breakout board (not the stock cover) to the Sidewinder X1.

You will probably need to add the `Material_Thickness` of this riser to the length of your existing screws. The default material thickness is 3mm.

If you are unable to obtain the exact lengh you can use slightly longer screws with some washers.

I am using this Hemera mount. I originally used 8mm screws to attach the breakout board to the circuit board mount and I am now using 12mm screws to mount this riser.

Installing

• Customise the riser or use one of the provided STLs and print it
• Attach the FFC extension PCB with double-sided tape or a sticky foam pad
• Secure the FFC extension PCB with a cable tie
• Connect the new FFC
• Attach the riser to your Sidewinder X1 with 2x M3 screws
• Connect the new FFC to the breakout board connector
• Connect the existing FFC to the FFC extension PCB

Versions

• 1.0 (5 Nov 2020) - Changed variables from camelCase to Underscore_Case and added `PCB_Tie_Slots` option.
• 0.3 (1 Feb 2020) - Added `Rotate_For_Printing`, `Inner_Cable_Slot_Offset` and `Outer_Cable_Slot_Offset` options
• 0.2 (29 Jan 2020) - Added `Parallel_PCB_Mount`, `Inner_Cable_Slot` and `Outer_Cable_Slot` options
• 0.1 (26 Jan 2020) - Initial version

Printing

Recommended slicer settings:

• Resolution: 0.1mm
• Infill: 50%
• Orientation: The best orientation for printing in will vary depending on the options selected. However, for best results, you should generally print this part with the PCB recess facing up. Enable the `Rotate_For_Printing` option to rotate the part in this orientation.
• Supports: Depending on the options selected, it may be necessary to use supports.
• Rafts: Doesn't Matter
