CR10v2 - Duet 3 Connections

BearcatTD

I went through the rep rap configuration utility as best I could for my CR10v2 - Duet 3 combo. I have included here text of the config.g file and an image showing the things I have wired up already. The things I have left are the X and Y Endstops and the BLTouch. I just want to ensure that I have these last things plugged in correctly based on the config.g file.

Thanks for the help!

Motor and thermistor config seems to match the inputs and outputs as marked yes.

So I guess I'm just confused where these last guys get plugged in. I'm having a hard time finding where on the board I find these:
; Endstops
M574 X1 S1 P"xstop"
M574 Y2 S1 P"!ystop"
M574 Z1 S2
M574 U2 S1 P"^duex.e2stop"

Same thing for the for the BLTouch
; Z-Probe
M950 S0 C"io4.out" ; create servo pin 0 for BLTouch
M558 P9 C"io7.in+io7.out" H5 F120 T6000 ; set Z probe type to bltouch and the dive height + speeds

The BLTouch has one plug with three wires and one with two wires.

Hopefully this makes sense!

I was wondering about that bit, my understanding is that you would have used IO_1.in instead of xstop but not my area of expertice.

Did you use the online configurator? Just tried it and it proivded a different, and probably correct output to me?

@BearcatTD see edit

BearcatTD

Thanks! Yes, I used the config utility online to get the above config.g file. I'll edit the file with your suggestions and give it a go!!

could you upload the config.json file it procuced? I would think devs would want to look at that if thats the output you got.

BearcatTD

Will do!

that is very strange, only issue I could see is the bltouch was split betwwen io4 and io7 , endstops should have come out as io1 and io2, smells like a bug.

BearcatTD

I'm glad to help...LOL!

A Former User

haha, you can laugh but if it saves someone else from banging their head against the wall its well worth it!

BearcatTD

Amen to that. Usually I'm the one doing the head banging. And not in an awesome 80' Rock way.

So here is the BLTouch Duet 3 hookup

I get the impression that the ground pin will have two wires?

Dealers choice. They're connected internally in the BLTouch and won't carry much current, so 1 or 2 will be fine when all connectors go to the same header imo. (but i suspect there are two grounds to insure signal integretry for RAMPS boards where the signal and pwm are split to different headers)

But yeah, I'd join them, its tidyer and you don't have one lead flapping about.
