Problem solved!
It really wasn't a big deal, I just had two probes to configure and my Z axis end stop was one of them (I had left the basic Reprap configuration). And when probing, each probe could be individually triggered and mislead the probing by scanning the bed.
So I'm giving you the corrected configuration for those who have this problem.
@dc42 Et bien j'avoue ne y avoir penser, effectivement erreur de ma par j'ai louper l'information sur la documentation ... En revanche j'ai donc quand même bien besoin des deux résistance comme sur le schéma ou éventuellement d'un abaisseur logique ?
Hello everyone,
I'll keep it simple and quick.
I've already read the different threads that talk about sending data in GCode from an Arduino but I want to be absolutely sure to understand everything, especially wiring and a little code.
A thread presents this schematic https://forum.duet3d.com/assets/uploads/files/1697735659312-duet3d-cnc-pendant-wiring.png
Does it allow you to connect the 6XD, its Panel I7 and the Arduino without an additional board and send it GCode?
In my case (large multi-axis CNC) I won't be able to slide an SD card onto the motherboard. So I need the second method of connecting the Panel with the “panel duet” port. (The only difference is that the Arduino is directly connected to the io_0 pin).
Another related question. About the code (I'm not the strongest on this side).
Arduino
void setup() {
Serial.begin(57600);
void loop() {
// Send Gcode exemple
Serial.print(g_code);
Will it be enough to send the information? (gcode is a text variable)
Duet 6XD Config.g
M575 P1 S0 B57600
Will it be enough to understand the information received?
Thank you in advance for your response.
To give more details: The goal is to create an ultra functional machine in “free access” of this fact to be able via a screen 10 inch touch connected to the Arduino to make a simple program for a fast and simple machining for all people. For example, you want to make 4 holes with 40mm and 110mm centres on a 500x500 plate, starting from the center. All you have to do is enter this information via a graphical interface, click on “ok” and you'll have your part back.

C'est une pince relativement grand, environ 50mm de diamètre.
Je vais tacher de faire ces meusures
@achrn
Non je n’ai changer aucun autre paramètre.
Pour ma pince, c'est une pince professionnel mais je ne trouve pas ses caractéristiques.
Je vais tacher de voir en contactant directement mon lit momentanément a l’alimentation pour vérifier mes résultats.
Et de modifier mon Gcode
Thank you very much for all your answers, they help me a lot to understand the various functions.
So far I'm still on 3.5 but I'm going to switch to 3.6 with the installation of the new cards.
When I talk about “error correction”, I'm talking about holding in position. I didn't know if it was the 1XD that took care of this or if it was the boxes of the different external controller kits. But now I know.
Indeed, on a CL-42-T controller I dismantled, I couldn't find much electronics, which is where this question came from.
On the other hand, one last question: for very complex machines with a large number of axes, would it be more “efficient” to have a main 6XD and then add 1XDs and another 6XD in daughter mode?

No, everything has always gone smoothly. But if I max out at 6.8 * 24 = +/-160W and 1.7 * 24 = +/-40W, could that explain why there's no voltage drop?
Hello everyone,
I'm going to add 3 new boards to one of my machines.
And I'm in dire need of information that I can't seem to find or understand.
I'm trying to find out how (in a rather basic way) data is shared and processed in a Duet environment with expansion boards.
My first question arose from the fact that my machine, equipped with a single Duet 3 Mini 5+ card, shows artifacts when turning at “high speed”. I've carried out numerous speed and acceleration tests, and yet (without exceeding the mechanical limits of my printer) at high speed, it still lets gohsting appear in combined/complex movements such as bends, exceeding 120mm/s. So I wanted to know if it's possible to saturate the Cortex M4? And if so, does it simplify calculations for the various movements? In my case, there are two X and Y motors set at 400 steps/mm for a speed of more or less 120 to 150 mm/s for a slicer part with Cura, which has a motion resolution setting of 0.01mm.
My second question is whether there's a way / a calculation to know if the calculations required of the processor by GCode are too complicated or not?
In the case of expansion board connections, a 3HC, which board will perform PWM, motors and temperature monitoring calculations? In a certain logic, each board only performs the calculations for its own sub-components (except for the main board, which also reads the code and compiles the information received by the CAN to display it on the screen)?
SBC mode can help relieve the main board of certain calculations?
My machine will soon have two servomotors in a loop connected to a 1XD daughter board, and I'm wondering if there might be a slight latency between the two 1XD boards (the X-axis and the Y-axis)? Especially in combined movements ...
Finally, I can't quite figure out who sends the correction command to the motor in the event of an error between the 1XD and the integrated box (for example, with a Cl-42-T box or much more powerful industrial boxes).
Many thanks for helping me out on this front.
@jay_s_uk said in Low heating element current:
maybe the rating of the bed and the hotend heater?
For the trays, no, it's a 320W. As for the hotend, I confess I haven't tested it with more powerful heaters, but I'm pretty sure I have a 60W (Chinese, but normally not the cheapest of all).
Hello everyone,
I'm going to install three new boards on one of my machines.
Just as a precaution, I'm interested in monitoring the temperature of my boards, but I can't find out if these two different types of board have an integrated temperature sensor like the Mini 5+.
Is this the case?
What are the commands to attach to my config.g if this is the case?
Thanks in advance for your help!
Hello everyone,
I'm experiencing a slight problem with the output current of my bed and hotend. Nothing alarming in the sense that they work and to my knowledge have always worked like that, but in the need to heat my machine much faster, I checked my amperages:
*to the current clamp
My board is a Duet 3 Mini 5+, so I should be able to get 15Afor the board and 5A for the hotend. However, this is not the case. There's no limitation on my power supply (LRS-350-24 MeanWell), whether the elements are switched on separately or not, the values remain approximately the same.
Where could the limitation come from? I don't have PWM limitation for my M307 controllers.
