Wiring DuetWifi/Voltage again
-
Thx for the answers and tips
Already thinking about 24V over all and the belted z-axis/leadscrews
-
Why not go with a single Z stepper and connect however many leadscrews you want to use with belts? I recently upgraded my D-Bot from a 2 leadscrew/2 stepper configuration to 3 leadscrews/1 stepper, and couldn't be happier. It's more stable, and I'm assured of my leadscrews not getting out sync with each other. With a stepper per leadscrew if one skips a step and the other doesn't your bed can begin to tilt.
The problem with multiple Z leadscrews is not that one skips a step and the other doesn't - if that happens you have bigger problems to deal with. The problem is that when you power the machine up, the motors jump to the nearest multiple of 4 full steps that matches the motor current, and they may jump in different directions. The new facility to auto level the bed solves that problem, but uses up another driver. The belted system is a good solution too.

As promised ^^ I am starting wiring
Yesterday all the parts (except heatbed) arrived and now i have some spare time 24V psu, mosfet and board are wired. Board is connected to the duet web control interface, wifi server is connected and working.
PanelDue is working too.So far so good.
Now i have to do some re-wiring of the endstops and the stepper motors and now i am kinda stuck.
Removing the wires from the dupont and re-attaching them in the right order is really very easy. Never thought that and i don't have to re-crimp all of the cables
Endstops are working but the stepper motors (42BYGHW811 2.5A) not
According to the left wiring diagram of the stepper motor and the duet wifi, the black and green are one coil and the red and blue are one coil:
I re-wired the cables in the connector in this order (to test the wiring i did this only for one motor at the moment, the others are not connected):
Original wiring:
Do i miss a step somewhere from the wiki/board? Orr missunderstood something?
Oh and i am using the PanelDue for moving the motors and the config-file is still the one provided with the board if this matters. Connected to the board are only the PanelDue, the x-endstop and the x-axis-stepper at the moment.

Does a M119 command show the X end stop being activated? That'll keep the motor from moving.
-
Have you homed the axis before trying to move it?
-
When you try to move the motor, does it vibrate noisily, or it is silent?
What config.g file are you using? If it's set up as a delta printer then the jog buttons won't work because delta printers have to be homed before it is safe to move them.
-
Don't think you need to change the order of the wires in the plug at all put them back and try again. and Follow DC42's suggestions to the letter.

Endstops are open.
I tried the tip from Jackal and homed the axis first and then i could move the steppers.
When i first moved one of them, all moved ^^ Changed the settings and now they are all moving as expected
@dc42
I used the original config.g file with the command to change to corexy.I configured new setting with https://configurator.reprapfirmware.org/ and added the T0 command at the end of the config file.
@Dougal1957
You were right, no need for changing the order of the wires!Now figuring out the BLTouch and still waiting for the heatbed
All in all i am still impressed with the Duet. The hotend temperature is constant, even without a pid-tuning.
The extruder steps are way off (instead of 100 mm it extrudes 460 mm) but i will figure this out too. Didn't had the time yet to dig into all the settings.
Great board, great forum. Thanks for all your help so far

M92 E*** divided by 4.6 will get your extrusion close.

I know
