Firmware Upgrade and Configuration.h settings

Hello Guys,

I have a 3D Printer made in Brazil which uses Marlin Firmware version 1.0.6, and I need to do some firmware changes as, for instance, enabling filament runout detection. Once I need to change the firmware I would also like to upgrade Marlin Firmware to the latest version 1.1.9, enabling also the improvements of that version.

The problem is: I don't have the parameters to set up the configuration.h file in order to compile Marlin. I've contacted the brasilian manufacturer of the printer but they refused to provide me the Marlin Firmware configuration.h file.

My first question is: Is the manufacturer obligated to share the configuration.h file (or the parameters that should be filled on it) once they use Marlin Firmware which is distributed under the GNU GPL3 license?

Thanks

Send a M503 to the controller the Data / information you seek will be returned, copy and past to notepad and print.

What is the Model an make of the 3D Printer you have?

Roberts_Clif,

Thanks for the quick response.

The model is GTMAX3D Core A1 (2016). As I said it’s a brazilian manufacturer.

But I still have parameter missing as the Z probe configuration for autoleveling, for instance.

This is true but look how much closer you are today.

You should be able to measure the Z-Axis Sensors location from the Nozzle.

What do you have for your end-stops / bed sensor.

It appears this is a CoreXY Machines if you ask under the topic CoreXY Machines and ask someone there may be able to help you further.

Actually, the auto leveling works with a metallic pin which is dropped down as the carriage touches the side of the x axis outside the print area. Then, the z axis moves the bed until it touches the metallic pin and lift it up some distance (until the pin reaches the optical sensor). After mesuring 9 point on the bed, the pin is lifted up by moving it to outside the printing area over the glass holder and a quick move of the Z axis that pushes it up. What I don’t know is: (a) what kind of probe is this? (I couldn’t identify between the options on the configuration.h); (b) is it necessary to write some code so the auto leveling would work or selecting the right king of probe will do?

Another question remaining is what kind of thermistor is used by the printer? I don’t know how to identify... (i’m I real rookie... kkk)

Also, I know that the board used is RAMPS 1.4 but I found that are many kinds of boards in the conf.h that matches this information and I can’t choose the right one...

By the way, it’s definitely a CoreXY.

Thanks for the help!
