Duet3 Homing failed

Usually this would indicate that when homing some axis the movement was completed without triggering the endstop.

Please cut-and-paste your homing code using the </> tag.

Thanks.

@fcwilt Thanks for the reply. The motors didnt move at all. Im using motors from Nanotec with built in encoders. They are connected to 1XD boards.

Please post a link to the steppers you are using.

Based on what I have read the 1XD boards are not for controlling closed loop steppers. The 1HLC board is designed to do that.

Can you please give us some more details about your setup?

Have you been able to get the motors to move at all? You can force the axis to report as homed without moving at all by sending G92 X100 Y100 Z10 and then carefully testing movement by sending G1 X1 F100

Also, what firmware version are you using? Please send M122 and M98 P"config.g" and post the results here.

@fcwilt https://de.nanotec.com/produkte/1604-pd4-c-schrittmotor-mit-integriertem-controller-nema-23-24

this is the motor. It is a closed loop motor.

Hammad

@phaedrux The setup is a Duet3 6HC and 3 1XD boards. I want to use 3 motors from Nanotec. I posted the link in my previous reply. i will post the responses from the mainboard in my next reply

@phaedrux these are the responses from the Mainboard

@hammad do you have a M291 command in your homing files? There is a known bug in firmware 3.3 that causes the homing failed message when you do that. It is fixed in firmware 3.4.0.

dc42

PS - I see that you have posted your homeall.g file and it doesn't include a M291 command. Nevertheless, please upgrade to firmware 3.4.0 because it includes fixes to bugs that affect 1XD boards.

Hammad

@dc42 I misunderstood the instructions and bridged erase. now i cant flash the firmware because BOSSA isnt detecting the board at all. How can I solve this issue?

Hammad

@hammad The Status LED is slightly on. I can't figure out why Bossa doesn't want to connect to the board. I've followed the instructions on how to upload the firmware if the firmware was erased. It doesn't work for me. I keep getting the error "could not connect to device on COM 22".

Hammad

@dc42 I measured the 5V to make sure I'm getting a stable 5V. I'm measuring just a few mV. The board is only connected to the PC using a high quality USB cable from ANKER.

Phaedrux

@hammad said in Duet3 Homing failed:

The board is only connected to the PC using a high quality USB cable from ANKER.

The Duet3 can be quite particular about USB cable and port. Please try some different combinations. Also make sure you remove the jumper after the erase.

Hammad

@phaedrux 3 different laptops and over 15 cables and still nothing. I removed the bridge from erase before resetting the board. I'm not sure what to do now. nothing seems to be working.

jay_s_uk

@hammad do you have a powered hub you can try with?

Hammad

@jay_s_uk Do you think this will solve the problem?

jay_s_uk

@hammad it has for people in the past. i've seen instances where standard USB doesn't provide enough power, especially laptops

Hammad

@jay_s_uk Thank you for the idea. Ill let you know in few minutes if this actually works.

Hammad

@jay_s_uk Thank you so much! this actually worked. It is writing the Firmware right now. It's been at 34% for a while now. I'm just glad that it connected!

jay_s_uk

@hammad one step forwards and all that
