BLTouch not working
-
I have been banging my head against the wall for a while.
Im trying to install a brand new antclabs BLTouch but there is no action.
Is it supposed to light up or something when it has power?I have another BLTouch I know work from another printer, i tried this but to no success.
I have read the probe installation guide and the problem-solving guide at Dozuki but i dont get it;
It says "Allocate an unused heater channel to reconfigure as the servo control for the BLTouch. For example, if the E2Heat output is unused, you can use heater 3 which corresponds to the PWM1 connector on DueX. On the Expansion Breakout Board, use heater 6 or 7."
I locate the E2Heat output on the Duex but where is the Heater3 output? Is it E3Heat?
It tells at Duex to connect PWM is it like E2_PWM? And +5V is like 5V AUX?
I guess i have to make sure the BLTouch has power, how to confirm that? Is it supposed to light up? I have checked and measured the wires a numerous times and the white/black reports 3.3 V and the red/yellow/brown show somewhere around 2 V.
I have attached the pictures of the wiring at the Duet and the Duex. And attached the config.g.

Yes it should do a self test when it receives power and light up red.
The photos of the wiring look correct, but if it's not getting power perhaps there is a break in the cable. I suggest doing a continuity test on your cables with a multimeter.
The config looks ok for RRF3.
Can you send M122 and M98 P"config.g" and post the results?

THanks a lot

I havent dont a continuity test but i have replaced all of the wires and connected the bltouch directly on the bord. But, with the same result.
If you are absolutly shure a test will be a good idea i will do it. What cables are preferably the best to measure? Which of the cables are power to make it run the self-test when it gets power?
Can you send M122 and M98 P"config.g" and post the results?

Have you tried connecting this BLtouch to one of your other printers? Perhaps the BLTouch itself isn't working.

I have don that some days ago. I will try again just to make shure thats not the problem.
-
@phaedrux Could it be an option to reflash the os from scratch?

I don't think it's going to make a difference.
The easy way to test the BLtouch is to connect 5v and ground and see if it lights up and tests the pin.

Thats the black and white wire?
-
No. On a genuine BLTouch 5v is red and ground is black/brown.
-
Are you refering to the brown on the PWM or the black on the Probe?
-
The red and black/blue show 0 Volt
-
@hsverre
Doesn't matter but disconnect the probe from the board..... -
I did that and the red and brown pin show 0 volt
-
-
No one of the PWM ports gives 5 V, all of them show 0 V.
And both the BLTOuches works fine on another printer. So they are ok.
There has to be something wrong with the power on the PWM pins
-
@hsverre
There is a jumper on the duex for the use of an external 5v supply.
Have you checked that?
-
@diy-o-sphere
I have played a bit back and forth with that pin. When in the position the schem show the PWM pins gives 2.658 V -
@hsverre
Set the jumper that way.(UTC+1)
-
BTW Do I need an external powersupply for the Duex other than the 12 V?
-
@hsverre
Only with big 5v fans....Edit:
To be exact larger consumers like LEDs, rc servos...... in total more than 1A on the 5v line.
