Tool board configuration

I've measured on the connectors on Toolboard which reads 5v.. but when connecting BLTouch it briefly drops below 3v, so my issues might be some voltage drop?

You could try adding a 100uF capacitor between the BLTouch +5V and ground connections.

Sidenote: I'm using a Quality Meanwell HRP psu. I measure output Volt at 24.2 at PSU and on Duet3 terminals,, while Duet3 reports it at 23.7v. Always... I find this somewhat.. odd? Using a decent quality Multiemter.

The Duet uses its 3.3V regulator as the voltage reference, so it can be few percent inaccurate. Your multimeter is probably more accurate.

Out of curiosity, do you have a terminating resistor on your can-fd line?

dintid

@Nuramori I don't know what that means? I have the requisite jumpers on my Distribution board.

dintid

@dc42 I only had a 35v 470uf. It didn't make a difference.
In your documentation you write that Orange i control wire.. but it's really yellow though?

It depends on your colour vision and how you assign colours. I see it as orange.

@dc42 I'm colorblind but asked my two girls who aren't
Any ideas to steps I can try to make BLTouch work on the Toolboard? I havn't had time to try it on the mainboard yet.

It's odd that it's not working, because BLTouch worked fine connected to the tool board when I took that photo. Are you certain that you have connected the wires correctly? The brown wire goes to ground (2nd terminal from the top) along with the black wire, which isn't clear in that photo.

Yea, I have it wired correctly. Might be faulty probe. It's rare but it happens.
I'm about to hook it up to Duet3 MB, and will report back

Is it genuine BTouch, or a clone?

dintid

@dc42 Genuine, I only use genuine.
I just tested with known good probe and it was a faulty probe, sigh. So much time wasted.
Works fine on Toolboard.. tried getting it to work on io5 on Duet3 without luck though for some reason.
