Problems with openbuilds control, ubuntu, Mega2560 and Grbl-mega-5x

This is my very first entry in a forum ever. Please bear with me if i've come to the wrong place.
I have already searched the forum for solutions to my problem, but have not found one.
So far I have used Open builds control under Windows 10 and everything has worked wonderfully. Unfortunately, I can't quite manage the switch to Linux Ubuntu (which I have installed on the computer in my hobby room). I can connect Open builds control to my milling machine, and commands via the Log / Serial Console are also processed. Even whole jobs are running. But commands via the user interface (e.g. +X / -X or setzero do not work. Immediately after connecting to the milling machine, the "GBRL Settings" tab is also missing. This only appears after entering $$ via the Serial Console. If G53 is entered, the board reports in the console that the coordinates have been set to zero, but the display in Open builds control does not change. Another problem is that a connection can only be established if the reset button on the Arduino is held down before clicking on the connect-button and releasing the reset-button shortly afterwards.


Here are the details of my setup:

Hardware: Controlboard Mega 2560 und Ramps 1.6 on USB port ttyACM0

Firmware: Grbl-Mega-5x version 1.2g dated 20220917

Software: Open builds control v1.0.371

Operating system: Linux Ubuntu 23.10



P.S. I can connect and program the Arduino Mega with the Arduino IDE under Ubuntu without any problems. The interface works in both directions.

Maybe someone has an idea what I am doing wrong.

Many thanks in advance WillyTwo

Thank you David for the very quick reply.
I spent a lot of time customizing the settings in grbl-mega-5x (config.h / cpu_map.h) for the ramp 1.6 board and the Mega2560 board. I was overjoyed to have done it after many attempts. I used very different software as controllers, such as UGS, bCNC, SerialComCNC and finally grblgru (which can also be used to control a 4th axis). All of them worked, but none of them could fulfill all my wishes. And so I tried Openbuild control. I came very close to what I wanted. And everything worked really well under Windows, including the 4th axis. When I now wanted to move my milling machine to my workshop and I only have one computer with Linux Ubuntu there, I thought I could get everything up and running again. Unfortunately, that was not the case. Everything worked, except for the communication via the graphical user interface.
It looks like I will also have to install Windows on the workshop computer to be able to continue using Openbuilds control with my machine. The program is really good!
Thanks again for the tips

It's a MEGA2560 R3 from ELEGOO, so not a genuine Arduino. If I see it right the Chip for the communication is Atmel MEGA16U2.

 

Thanks for the tip and many thanks for the great control software. I really enjoy working with it. I understand that I need to get some other hardware as far as the Mega2560 is concerned. Unfortunately, this means a lot of work for my machine when converting it. Of course, I could simply use your black box, but I'm not there yet. I will try out a few more things and then report back.
Until then, thank you
Best regards

Hello everyone,
I have just said goodbye to openbuilds control. Two reasons for this:

1. I can't get the software to run under Linux. After a lot of research I came to the conclusion that it must be due to the communication between openbuilds control and my Mega2560 controller. There are no communication problems with other programs. Commands were also recognized via the arduino IDE and correct responses were sent. So openbuilds is actually not suitable for the mega 2560 under linux

2. The main reason for uninstalling openbuilds control is the fact that the program starts via autostart, which cannot be deactivated. This is very annoying and unacceptable.

Too bad, because the software is otherwise actually quite good.
Kind regards
Willy Two

 

On point 1: If the Mega 2560 and grbl-mega-5x are the problem, why does this combination work flawlessly with openbuilds control under windows?
Point 2: If it starts and does nothing, why does it start at all? I just don't like it when programs start without being asked. That's just the way I am
