ok, found the solution, tried with enabled pin in and out didn't work, but tried something rather simple after seeing this dozuki page ( I don't know how I missed it before ! )... rather than connecting the TB6600 GND to the E2_STOP, I connected it directly to the GND on pin number 2... works perfectly now !
so the correct pin layout for me was :
E2_EN to EN
E2_DIR to DIR
E2_STEP to CLK
GND to GND
and for the mode selection on the TB6600 :
TQ OFF ( AUTO )
I'm so happy this finally works !
@PhoenixSimon In decreasing order of likelyness:
simply crimp both the servo wire and the capacitor leads into the terminal and maybe add some sleeving on the exposed part of the leads
solder capacitor to the bottom of the board, onto the solder joints of the servo header.
remove the plastic "shroud" for the servo header then wire wrap + solder the capacitor leads onto the bottom of the header pins
solder capacitor to pcb inside servo, 3d print new cover.
Additional some information.. maybe.. who knows what one of the problems.

I´v done sucessfull a update.. so I´m actual at the newest Firmaware since two weeks.
The Powerin is 24V 360W for Board´s and Nozzle-Heater H1
Bed (H0) has it´s own Powersupply weith 600W
How can I check the DUEX-Board.. for correct function or is it enogh, if the Z-drivers working?
@dc42 said in 12v Water Pump on a 24V System:
We recommend that you do not run water pumps that used brushed DC motors from the fan outputs. This is because the starting current for a brushed DC motor is usually many times the running current, and will probably exceed the 4.4A rated current of the bed mosfet.
If your E1 Heat output is free then you can use that to drive the water pump; but then you must use an external flyback diode.
Maybe add that to the warning about adding diodes to brushed motors in the wiki for completeness? (And good catch!)
This meanwell PSU has the function. See the lat page of this manual: http://download.lulzbot.com/retail_parts/Completed_Parts/24v_500w_PSU_KT-EL0063/RSP-500-spec.pdf
It works the opposite way of ATX power supplies: apply voltage to turn OFF the PSU.
thanks, when I mesaure across GND and Z PROBE IN I get constant 3.2v, when probe is not triggered and around 17v with a 10k resistor. without the endstop connected I also read 3.2 between GND and Z PROBE IN, is there something defective?
@colten said in FET wiring:
I've got a parts cooler and a hotend cooler that I would like to control with 3 wires. On a Ramps 1.4, I would connect both positive's together and use the negatives to control on/off with the ramps FET's. Is this possible with the Duet 1.04? Ive looked for a schematic but could not find one.
Yes, you can do the same on the Duet.
@thomas_rudloff said in Z endstop at high end should set Z position to maximum:
Z endstop at high end should set Z position to maximum and not to zero after homing.
It does if you have declared your Z endstop to be at the high end in your M574 command, unless you have overridden that using a G92 command in your homez.g or homeall.g file. https://duet3d.dozuki.com/Wiki/ConfiguringRepRapFirmwareCartesianPrinter#Section_Homing_Z_to_a_Z_max_endstop_switch
@daydreamn1134 said in is this a Hardware issue? Duet WiFi does not boot.:
after fiddling around a bit more I tried yet another USB cable. while plugging it in I noticed that the other LEDs flashed quickly. I very gently wiggled it just slightly and the all stay on as long as I don't breath. The board now is booted up and I was able to connect to the board and configure and am able to access the board over wifi..
Maybe I have a bad USB port on the board @dc42 ? What are your thoughts?
Yes it could be a bad USB port, either bad contacts inside the connector, or a bad solder joint between the back of the connector and the PCB. Those solder joints rarely cause trouble, and they can be inspected easily. Do they look OK?
@pkirill said in Fans running only when tool is inactive:
When I connect a second fan to the second always on and turn on the power, the fuse blows.
Do you have the red and black wires the right way round? If you do then that second fan is probably faulty. I am assuming that they are not very powerful fans such that the combined total load is well over 1A.
I'm sorry, it looks like one of the stepper drivers has suffered infant mortality. If it's a genuine Duet then this is covered by the warranty, so you should contact your supplier to get it the Duet exchanged.
If you want to postpone swapping the Duet for a few days, you can use the E1 motor output instead of E0 by adding this line to config.g (earlier than any M906 or M350 lines), assuming you don't already have a M584 command in config,g:
M584 X0 Y1 Z2 E4
