Toolboard 1LC on Voron 2.4R2 Stealthburner CW2 Question

c_ern

Hi,
now that I've finally found a way to mount my Toolboard 1LC V1.3 to my Stealthburner CW2 extruder , I now will have to wire it up. And that's why I would be happy to get some clarifications (I'm referring to the documentation most of the time):

for using the CAN connection, I only need to bridge the solder jumper without the need to bring a physical resistor into the circuit, right?
How crucial is it to especially use twisted pair as CAN wires? I would like to use my Heluflon 0.25mm² (AWG 23) cables because they are quite flexible. Can I do this?
Can I use a RJ11 adapter to connect the cables to my Mainboard 6HC? Something like this?
If I understand correctly, there are limitations in RRF so that I cannot use my inductive probe Omron TL-Q5MC2 with the toolboard. For the start, I will connect it directly to the Mainboard and then I will likely switch to Voron Tap. Can I connect the sensor of it to the toolboard? I suspect it's probe type 8?!?
Do you have any suggestions on how to ground the whole toolhead effectively? I see I can connect a wire to the screws holding the toolboard - where on the metal parts (especially the gears) should I connect a ground wire to?
At the moment, I don't see any possibility to connect toolhead LEDs to the Toolboard. It's not crucial, but nice to have nonetheless. Do you have any suggestions on how to do this?

I know, that's quite a bunch of newbie questions, but you would help me a lot in answering!
Thank you!

While I can't answer all of your questions I have a very similar setup with but with a 1LC V1.2.

I believe this is the case. I put a resistor in the wiring because it allowed for more flexibility in the future. May want to wait for others to chime in.
I think I was one of the first people to have a version 1.0 1LC on a V2.4 and ran into canbus errors when i ran standard wiring along the cable chain. Others didn't have the same problems I did. I ended up with shielded wiring and ran my Z axis stepper motors outside of the cable chain. That being said I think twisted wires are a minimum requirement for this length of run. You can always twist them yourself.
Yes you sure can do this.
If you can swing it I would just start with tap (or klicky). The Omron probe was finicky for me and melted several times. I've used the Omron probe, a Chinese version of the Omron, BLtouch, Klicky, and Tap. Klicky and Tap are by far the best.

The tap connects directly to the 1LC; in my case IO2.
Here is my current voron tap config:

;Voron TAP probe setup
M558 P8 C"!20.io2.in" T18000 F150 H5.0 A1 S0.01 B0 R0.0 K0
G31 K0 P25 X0.0 Y0.0 z-0.8

And just for reference here was my Omron config:

;NPN NO switch (stock voron sensor)
M558 P8 C"^0.io5.in" T18000 F600 H5 A3 S0.01 B0 R0.2 K0
G31 K0 P25 X0.0 Y25.0 z2.458					         ; set Z probe trigger value, offset and trigger height,

I didn't ground the board separately. Sorry can't help much with this one.
Not sure on this one, I need to do this still someday.

Hope this helps.

yes the jumper connects the the built in resistor into the circuit

It depends on your CAN bus wiring length you can start with that wire if its a typical voron 2.4 size machine and you will probably find it works well.

you can connect the Z probe to the toolboard. the limitation was removed a few firmware versions ago (see https://docs.duet3d.com/en/User_manual/RepRapFirmware/CAN_limitations) you are right you are limited to types 8 and 9.

the toolboard v1.3 had a connection to ground (via a bleed resistor and filtering capacitor) from the mounting hols so if you mount it with metal fixings. This means that static generated in an extruder can have a path to ground via those mounting holes. This was especially relevant when mounting it onto the side of Hemera XS (metal extruder body, metal mounting hardware - instant path to ground). Grounding the CW2 completely, with all the plastic parts would be challenging, that said the failure mode we are trying to prevent with the grounding is static buildup in the extruder founding a path to ground via a circuit like the thermistor circuit and frying it. I expect it would be sufficient to ground the extruder heatsink.

This is no Neopixel output on the 1LC. IT may be possibly to drive a couple of LEDs from the onboard 5V regulator, more from an external 5V supply however firmware work is required to support it. This is logged as a feature request here:

@Alex-cr using the 3.5.0-rc3 firmware version it is possible to drive a few Neopixel LEDs from the IO0_OUT pin.

Awesome I missed that capability!
