Z-probe already triggered ...

roguebyte

I am building my delta printer with a Duet WiFi and Smart Effector v1.3. When it powers on I do not see any flashing on the LED. I have checked the voltage at the wiring on the effector, and there is 3.24V between pin 6 and 8. Duet web control shows Z-Probe at 1000. G32 and G30 say Z-Probe already trigged at start of probing. I do not have the part cooling or hot end fan running, neither the heated bed.

Any recommendations or other information I should provide?

Thanks.

@roguebyte Please send M115 to your Duet, and post the response. This will show the firmware version you are on. Also please post your config.g file.

Most problems are either configuration, or wiring. Check continuity of the wires, and check with the wiring diagram where you have plugged them in. Maybe a quick picture of the Effector wiring, and of the Duet showing where the wiring is connected would also help.

Please disregard the wiring of the power connectors in the background of the effector picture, I know I have to fix this.
And as I stated before, I can read 3.24V between pins 6 and 8 off the wired pins on the 8-pin molex.

Danal

Wiring looks correct in the photos. When you measure voltage, are you measuring the pins on the board (carefully!) from below, with the connector plugged in?

It should at least self test as it powers up.

@roguebyte That looks to me like the Black Earth wire isn't seated in the plug at the Effector end which if I am right would explain why it doesn't appear to power up.

Would check the the pin is inserted fully into the shell and locked in place!

@roguebyte Looks like the blue wire connection to the board has got bent back too:

Thanks everyone. Turns out it was my faulty crimping. I cut off all the wires on the 8-pin Molex and crimped them again. Admittedly these were my first crimps in this project and weren’t my best. LED flashes after power up and successfully ran auto-calibration.

Just have to fix the crimps on that power connector and I’ll be testing the hot end and extruder.

@roguebyte one of those instances where a picture is worth a thousand words!

Glad you got it sorted!
