CW2 With ECAS04 and Optional Sensor Kit
Couldn't load pickup availability
CW2 ECAS04 input mod hardware kit for ERCF-style filament paths. This kit supplies the purchased hardware for the Clockwork 2 usermod that adds a press-fit ECAS04 fitting to the CW2 filament input, with the optional mechanical filament sensor hardware included.
Why this mod exists
- Adds an ECAS04 embedded collet to the Clockwork 2 filament input so the PTFE tube is retained during ERCF loading and unloading.
- Supports the optional ball-bearing microswitch sensor documented in the CW2 ECAS usermod.
- Uses a mechanical sensor design: a 7 mm ball bearing is pushed by filament and actuates a microswitch.
Kit contents
- 1× Omron D2F-series microswitch
- 2× M2×10 self-tapping screws
- 1× 7 mm ball bearing
- 1× ECAS04 embedded collet with clip
- ~18 in / 1.5 ft of 30 AWG FEP wire
Fitment and source project
- For the Clockwork 2 (CW2) extruder usermod: CW2 with ECAS fitting, with or without ball bearing filament sensor.
- Based on the Voron Stealthburner / CW2 design state documented by the mod author from August 18, 2022.
- Useful for ERCF builds where the toolhead input tube needs better retention than a bare filament path.
Important gotchas
- This is the hardware kit only; printed CW2 mod parts are not included.
- The source mod says these parts are not compatible with pre-RC1 Clockwork 2.
- The source mod shortens the lower filament path by 3 mm; follow the project instructions before cutting PTFE.
- The sensor is mechanical, not the standard ERCF Hall-effect toolhead switch design.

Shipping:
US Shipping is via UPS or USPS. The way it is set up shows the least expensive options for standard, priority and express shipping. I can not take special requests for specific carriers at this time.
International shipping is mostly UPS, as I utilize Zonos/UPS integration to tally extremely accurate import and shipping costs.
I require a telephone and email with international orders and you must make yourself available to the carrier or your customs, should they require more information. If you are unreachable and the package is discarded or rerturned, I will not be responsible for rerturning your shipping cost.
If there is a problem with an international order, it is my choice to refund part or all of the order, or send a replacement.
Addresses are verified through Shopify, but the customer is still responsible for inputting their address in the correct format. Any returns or lost shipments, due to incorrectly addressed packages, are the responsibility of the customer.
