In the bottom right, there is a number "TEAN E120339". Google that. I did it quickly and it came up with a load of images. I just clicked on one of them and it said "MK808B Clone"

You cannot download a configuration.h from any ardunio based board

If your lucky M503 will tell you some settings. But never all of them.
X and Y travel is not normally displayed or editable in gcode unless printer support M208 command, documentation says that this is only in "RepRap Firmware"

Contact your supplier for source code and configuration.h

Your processor is a ATMEL 644p

This is common on melzi and Sanguinololu and pre v2 gen 7 boards

If your lucky your board is compatible with one of those

You only need a ISP if you a) need to upload a boot loader b) change cpu fuses c) upload firmware when there is no bootloader

It should have a bootloader, and with that you should be able to upload a new firmware over usb

You can also use another atmega board as a ISP

Salve, ho trovato una stampate 3d praticamente uguale alla tua, vorrei vedere se è funzionante, ho cercato di farla funzionare con vari programmi di slicing ma inutile, e visto che tu forse te ne intendi di queste cose vorrei sapere se mi potresti dare una mano a metterla in moto.almeno mi sarebe utile qualunque informazione su di esso. O paura che può farsi qualcosa o inserito male può darsi,non sono esperto.lo provato con repetier-host ma mi da sempre comunicazion timeout - reset buffer Block, 20 ore di montaggio studio e prove e ancora non si a mossa nula. Scrivimi alla mia email slava.super@libero.it, Grazie!

Ciao Adriano , sono appena iscritto , ho letto tuoi messaggi di circa 6 anni fà , ho una stampante che monta lo stesso chip ATMEGA644PA 1535
vorrei chiederti se eri riuscito a cambiare il firmware , se si quale tipo scheda é e che boot loader hai usato .
Grazie

ATMEGA644P is just the processor. that is not enough information to identify the controller board (ie which pins are connected to what function)

Resume its got no bootloader and put one on it.

the 644p is to small for most modern firmware except for the most basic of machines.

In my view if you have atmega644o based controller, it is time to replace it with a stm32 based controller.
