@logan I think it is time to begin work on a cable harness test fixture using the extra cablescan we have in MER.

@kent Is this to be limited to this harness or should more be included?

Let's start with this one, but make it big enough to add more later as needed.

I have built and modeled the panel frame and requested these crimp on terminals to connect to the purple faston connectors: https://www.digikey.com/product-detail/en/te-connectivity-amp-connectors/62887-1/A125118CT-ND/6810819

I will need those to complete this.

@MikeR where are we on this?

Im pretty sure we got the connectors in. This has kind of gotten put on the back burner.

Per my discussion with @cmerot this will be expanding to include internal harnesses for the event that they are built in house as well as any externals that are not built by Igus.
Harnesses to be included on this stand:
EL-HR0148 - CB Bed Power Harness
EL-HR0149 - CB Y/Z Harness
EL-HR0150 - CB Z Endstop Harness
EL-HR0151 - CB X Harness
EL-HR0153 - CB Extruder Sensor Harness
EL-HR0155 - CB Bed Harness
EL-HR0156 - Erase Switch Harness
EL-HR0142 - Z Max External
EL-HR0143 - Y/Z Harness
EL-HR0144 - Filament Sensor Harness
EL-HR0145 - E1 Extension Harness
EL-HR0146 - Bed Extension Harness

Correction: EL-HR0147 can be tested on an existing cablescan stand, like Mini 2 is.

Harnesses are being outsourced and with current workload this will not be complete before their arrival so this project has been placed on hold.
