@droftarts said in Problem in endstop triggering:

Are you sure both 1XDs are running the same version of the firmware as the 6XD?

Checked the firmware version on main board and expansion board, both are running at 3.4.4

@jay_s_uk said in Problem in endstop triggering:

looks like you have them wired as normally open and they're picking up interference. Wire the normally closed instead

I have tried with the normally closed connection. But when triggered it goes to the floating state even triggered all the time.

All the motors are in ON state in the case 1;(Without connecting the expansion board). During which no floating state occur, so I think its not a interference problem.

Here is my Diagnostics report

edit: I have changed my CAN address of both board as 40 and 41

Hi, I am using Duet mainboard 6XD and 2 1XD expansion boards operates with the firmware version 3.4.4. My endstop is configured in main board at I/O port 1 and 2 for X and Y axis.
Using a switch type endstop which is connected to input pin and ground of each specified port(i/o port 1 and 2) with an pullup enabled(by firmware).

Case 1: DUET MB 6XD with no expansion board connected
Endstop works normal and finding no issues.

Case 2: DUET MB 6XD with expansion board.
Works fine when endstop triggered. If not the endstop is in floating state(which means showing triggered and not triggered randomly).
These state changes randomly even the endstop is not triggered all the time of this process.

Endstop wiring remains same for both the cases which is 1wire to input pin and another to GND.
Below is my config file.

I don't know what's the mistake if it works fine when no expansion boards are connected.

Any help is appreciated. Thanks in advance.

@Phaedrux
Yes, the driver has step/dir signal.

We need to connect the following driver with the duet mainboard 6HC. How should I connect the driver with the mainboard? After going through some documentation, GPIO can be used to generate PWM signals. If so, how do I generate PWM signals in the GPIO pin?
@T3P3Tony @dc42

We are required to connect a servo motor with the following specs,

50 W to 22 kW,
Input power supply for Driver: Voltage DC 24 V/48 V・AC 100 V/200 V/400 V,
23 bit Absolute/Incremental・battery-less Absolute/Incremental encoder,
Frequency response 3.2 kHz

How do I connect this servo with my duet board(Duet MainBoard 6HC)? How to configure this in the RepRap Firmware?

@dc42

@JoergS5 Thanks for the knowledge, will look into it and respond

We are currently developing a robotic arm 3D printer. We have to configure the RepRap firmware for the Robotic Arm. We need help in how to start configuring? Also I have doubt that how these 3D models are sliced for the Robotic Arm 3D printing?
Thank you in advance
@dc42 @robm

@fcwilt
Thank You for the clarification. Now I get it. I have tried it via router and now it works fine.

@droftarts
Thank You for the clarification. I was connecting the ethernet cable directly with my laptop. Now I have connected through the router and It works fine now. Thank You once again.
