Older kits still came without the Orbiter Smart Sensor 2. That also means the Hex standoff M3x20x4.5 is 3mm too long. You need a 17mm standoff to make this work to retrofit the filament sensor.

Of course RatRig doesn't include 17mm standoffs while selling you 2 filament sensors for your V-Core 4. (They don't even tell you that you need them, even when explicitly told that you're buying them for a V-Core 4.)

For my these two screws came in a separate small bag labelled: Low Profile M3*6 SS304 BLK (SKU: HW3917SC)

Consider mounting the Beacon probe here. If you do it later, you'll have to do it upside down while crawling under your toolhead.

See steps 35, 36 to decide:

08. RatRig V-Core 4 Toolhead

Install the tensioning screw after mounting the extruder to the toolhead plate. (It's in the way of your screwdriver.)

Do not Install the tensioning screw at this moment. Wait until you're mounted the extruder to the toolhead. Otherwise you'll have to take the tensioning screw out again, because it gets in the way of your screwdriver to mount the extruder to the toolhead.

The 1st picture shows to separate the pancake-stepper from the gear-housing. This is not necessary. You can just rotate the pancake-stepper by 180° in place without risking any misalignment or damage to the gears.

The 3rd picture shows to separate the pancake-stepper from the gear-housing. This is not necessary. You can just rotate the pancake-stepper in place without risking any misalignment or damage to the gears.

6 months later, and not only has the connector issue not been resolved, the documentation hasn't been fixed either.

The whole problem could be easily, and reliably, solved by including a short adapter cable for connecting the hotend and thermistor to the toolboard.

I totally second that frustraton.

RatRig should also provide a way to replace the wrong connectors for existing customers. (Even if for a small hanling fee.)

Another component that doesn't come with the correct connectors. Another opportunity to damage parts.

If you're struggling hard with crimping tiny connectors, like I do:

There are adapter cables in the toolboard box provided by BigTreeTech. These can be used to make correc tconnection.

They're unsuitable for mounting on the toolheads directly to connect the hotend to the toolboard because the cables are 2m long. (They're meant for connecting to a controller not on the toolhead.) Using these cables adds 40g to you r toolhead and a mounting problem for 4m of cable bunch. → Not a viable option for printing.

@ratrig Please provide short adapter cables that can actually be used without having to crimp another wrong connector. I'd even buy them just to avoid crimping.
