How may I identify the firmware in use on my 3D printer?
I have a generic printer with no support documentation.
How do I determine what firmware is in use so that I can research how to make the print run?
M115to the printer. This command is
Request the Firmware Version and Capabilities of the current microcontroller.
ok PROTOCOL_VERSION:0.1 FIRMWARE_NAME:FiveD FIRMWARE_URL:http%3A//reprap.org MACHINE_TYPE:Mendel EXTRUDER_COUNT:1
For more info see here, RepRapWiki- G-code - M115: Get Firmware Version and Capabilities.
Of course, this isn't guaranteed to tell the truth, just whatever your generic clone firmware had in its source code.
Tour board probably talk serial. Use marlin or repetier host to send the gcodes to your printer
After much research I am still with no answer. The printer is stand alone. I cannot connect it via marlin or repetier as I believe that requires connecting by USB. USB connect fails with Device Descriptor Request Failed. How do I identify the printer in order to get a drive for it? or am I barking up the wrong tree.
@Gord It is very unlikely your printer needs a printer-specific driver. Take a look at the mainboard to see if you can identify the USB-to-Serial converter, and install the driver for that. It's usually either an FTDI (clone), CH340 or AtMega32u4-based one.
Another option to send gcode to your printer is the "Terminal" tab in OctoPrint. In general OctoPrint is very convenient, worth the $20 for a RaspberryPI.
Sending G-code commands to a printer is described in this question.
Usually, when a printer starts up, the screen shows a boot-screen. This contains usually the firmware version, but not who or what the settings are.
LCD: About Printer
Some printers have an LCD main menu item that is "About Printer" or similar. It would one of the last items if enabled.
In Marlin it is disabled by default, and you'd need to uncomment
Connect a terminal and send
M115. In most cases, this will tell you the current Firmware and version, as it is annotated in the firmware. This doesn't mean that those lines always were updated by who changed the files, but it is a good indication what was the basis for the installed firmware.

Please excuse my beginner state. I have the printer assembled and turned on. It has an SD card. I was hoping to learn how to 'send' it anything. how does one send an M115 to the printer. Create a .bat file for the SD card?
