hi my duet 3 6xd wont boot it cannot be found on my pc they asked me to use the delete jumper done 6 times can yo help me

@gardon64 The delete jumper deletes the firmware. You will need to follow the instructions here to flash the firmware to your board: https://docs.duet3d.com/User_manual/RepRapFirmware/Updating_firmware#all-other-duet-boards

However, before doing this, check what LEDs come on when you connect USB power to the board. Follow the troubleshooting guide here, and report back what works/doesn't work: https://docs.duet3d.com/User_manual/Troubleshooting/Duet_wont_respond

thank you for that
next to usb red then green then third red

bossa downloaded but cannot install

[dc42]

@gardon64 what error message do you get when you try to install it?

[gardon64]

@dc42 no exe file

[droftarts]

@gardon64 download Bossa.exe from here: https://github.com/Duet3D/BOSSA/releases/tag/1.9.1a-duet3d

thanks for the help this is where i got it from git hub

What exactly happens when you follow the steps in this link?

[gardon64]

Thanks for the help board running I have set up 1 stepper motor and driver to test stepper but dose not run software said it moveing but not .sorry for being so thick pls help

@gardon64 It is almost impossible to support you when you supply so little information. See https://forum.duet3d.com/post/53522 for a list of information we need to help you. All we know so far is:

• You have a Duet 3 6XD
• You have managed to get some version of the firmware and Duet Web Control (DWC) working on it
• You are using an external driver and stepper motor

At the very least, we need to know:

• What version of RRF you installed (send M122 and post the response)
• What stepper driver you are using, with a link to the datasheet
• The config.g you are using (contains details of how the drive is setup)
• How you have wired the stepper driver to the 6XD
• From turning on, what commands are you sending to replicate the problem

There are a number of other threads dealing with external stepper drivers recently, and the issue is usually either the wiring to enable the driver or the stepper driver timing, for example:
https://forum.duet3d.com/topic/32437/external-driver-and-duet-1xd-issues

Really, Ooznest should not have told you to delete the firmware from the board. It's highly unlikely that is what caused the initial problem.

hear is the m122 result
console.txt config.g
using dm542t drivers
wired up as in stepper motor on duet 3d for duet 3 6xd with sbc
sending m564 so ho first
then using x- and + on duet three
hear the motor make a sound but will not move

[gardon64]

hear is the data sheet DM542T_V4.0.pdf

[droftarts]

@gardon64 Okay, so the stepper driver is connected to the 6XD driver 1 outputs? How have you wired it? Like in the documentation here: https://docs.duet3d.com/Duet3D_hardware/Duet_3_family/Duet_3_Mainboard_6XD_Hardware_Overview#connecting-external-motor-drivers ?
Post a picture if it helps.

How are the jumpers on the external stepper driver set?

Your config.g has no stepper driver timings, so it will be using the default, which are too fast for the external driver. According to the data sheet (page 10):

a) t1: ENA must be ahead of DIR by at least 200ms. Usually, ENA+ and ENA- are NC (not connected). See “Connector P1 Configurations” for more information.
b) t2: DIR must be ahead of PUL effective edge by 5us to ensure correct direction;
c) t3: Pulse width not less than 2.5us;
d) t4: Low level width not less than 2.5us;
e) Duty cycle of Pulse signal is recommend 50%

So try:

M569 P0.0 S1 T5:5:10:10                            ; physical drive 0.0 goes forwards

Also disconnect the enable wires as the driver expects these to be not connected by default. If you want to try keeping them connected, add R0 or R1 to the M569 command above.

This is pretty much exactly what was described in the post I linked in my earlier reply.

Steppers now turning thank you so much
