ok so leave vin alone then?
also I have two of these boards will I be able to stack them on top with same pins except the cs pin and use cs2 for another board

Yes.

Glad you figured it out.

Ordered the connectors, Thank you!

We need more information to be able to help you.

should be fine to wire fault- to ground and fault+ to stp, even for multiple fault+ signals to the same stp pin.

edit: stp is the silkscreen label, the wiring diagram says e1stop, just to be clear.

edit2: by the looks of it you should use ^ in the config to enable internal pull up of the endstop pin name.

@Phaedrux
It's a Conductive probe (NPN & NO) I've used it before with little to no problems (except the temp-related failure in a heated chamber)
LJC18A3-B-Z/BX also works on wood and other materials.
Which is the reason, why I had it on my CNC as well.
(try DC42's mini IR probe on shiny metal, just for fun...)

@Hélder-Rocha said in BLTouch Config.:

@Veti can you tell me how to use the </>? I dont know how and i´ll like to do it correctly!

When you click that button in the post creation window it adds a section between three dots above and below. Put your code in the middle where it says code_text.

https://forum.duet3d.com/topic/8934/inverting-ps_on-levels

Thanks I have found that thread already myself but it did not help me a lot. As I said, I am not much of an expert in electronics. The solution with the PCB at the end of the thread seems to be for an MW RSP-500-24 which is a bit different than the RSP-1000-48 I have. For instance, the logic levels for remote control are not inverted here and apparently directly compatible with the Duet. Also in my case I do not want to turn on/off the PSU that directly powers the Duet but only a 2nd PSU.

Hence, the question if I still need the PCB or if I can connect the PSU directly to the Duet and if yes, to which pins?

@fcwilt said in Question about M591:

I miss the days when my eyesight was better and my hands were steadier.

I use 3.5 diopter reading glasses when soldering.

@hackinistrator said in trying to understand diagnostics (M122):

what is the min/max pulse width for the under voltage event to register ? i would like to test that .

It's 1ms.

.i think the default homing sequence should be better .

even my 6 years old 8bit board checks if the endstop is pressed before homing , and if it is , it tries to move the motor in the other direction to see if the endstop state changes . if not then something is wrong , and you hae an error.

You can do anything you like in the homing files. We'll look at making the homing files generated by configtool do as you suggest.

@rilot said in Which component on Duet 2 Wifi would cause serial ports to fail?:

Thanks. I thought it might be.
I'll have a go at replacing it. I've replaced the board so might as well have a go and see if I can resurrect this one.

Be very careful not to lift any of the traces that the MCU pins are soldered to. Use a suction device to lift the MCU off the board.

Thanks for your help !
Problem 2: With “T0” to the end of config.g all work perfect.

Problem 1: I find the problem: now work all good !!!

; homeall.g
; called to home all axes
G91 ; relative positioning
G1 H2 Z5 F6000 ; lift Z relative to current position
G1 H1 X-235 Y-228 F3000 ; move quickly to X and Y axis endstops and stop there (first pass)
G1 H2 X5 Y5 F6000 ; go back a few mm
G1 H1 X-235 Y-228 F240 ; move slowly to X and Y axis endstops once more (second pass)
THIS IS TE PROBLEM !!! G1 H1 Z-255 F240 ; an old command in RRF2
G90 ; absolute positioning
G1 X110 Y110 F3600 ; Posiziono la sonda al centro del piatto
G30 ; Sondo il piatto con il BLTouch
;END

Thanks again !

@fcwilt, sounds exciting. Please let us know if you will find anything interesting.

@FG-Dynamika said in Duet 3 Not responding:

When you connect it to a PC and then go to device manager the icon is a yellow triangle. The error is device descriptor request failed. I have tried uninstalling the device. Power on-off cycling the pc, isolating the pc from ground, and through multiple powered hubs and usb-port clusters.

Please contact your vendor and initiate a warranty exchange. Please include a link to this thread as authorization.

I have increased the max length of the pin name string in the forthcoming 3.2.1 release.

Can you please measure the resistance of the heater cartridge?

Are you sure the heater is 24v?

It is going to be changed a lot (bed is going to be reduced to 1000mm instead of 1400mm), maybe change the Gantry, way too heavy right now...

@Phaedrux no offense. The purpose of making this PCB is not to sell it. I think I should close the theme

it was the G30 that was missing :

the new code :

; Uncomment the following lines to lift Z after probing G91 ; relative positioning G1 Z5 F100 ; lift Z relative to current position G90 ; absolute positioning G1 X80 Y50 F6000 ; put head over the centre of the bed, or wherever you want to probe G30 ; lower head, stop when probe triggered and set Z to trigger height
