According to a few guides I’ve read, ARC_SUPPORT isn’t something that 3D printers normally use, so I disabled that by commenting out #define ARC_SUPPORT in Configuration_adv.h. Again, many of the guides online suggest using Arduino IDE. This is probably convenient if you are connected directly to the printer, but again, I have the Raspberry Pi setup to flash the firmware.
Take the files that we’ve copied and place them in the ‘Marlin-2.0.x/Marlin’ folder from the previous step. If files with the same name exist in that directory, overwrite them with the new configurations. In the ‘config/examples’ directory firmware files, we’ll find a list of folders belonging to different manufacturers. There is a collection of sub-folders inside of them, one for each 3D Printer that company has released.
One of the last ‘free’ upgrades to my 3D printer that I hadn’t done yet was updating the firmware to the latest version of Marlin. Once the folder is opened, you will expand the Marlin folder on the left and side and then double click on the file called “Configuration.h”.
This will cause the printer to flash the firmware from the SD card to your printer CPU. There are many other options in the firmware for setting up upgrades, tuning, and other features. Read through the files configuration section to see all the features we’ve put in the firmware for you. In the configuration.h file there are printer models you can uncomment to tell the firmware what machine you are setting it up for.
- It is not uncommon that a 3d printer suddenly has a shift in the X or Y axis at a random layer and all of the remaining ones.
- For example, if your X/Y/Z acceleration is not setup properly then your machine can engrave with black spots.
- If you notice that the first layer is too high or too low, re-adjust the Z offset accordingly until you are getting perfect first layers.
- Finally, you would click on “Firmware Update” and all the relevant information will pop up, including the current firmware version that your printer is using.
- Oh, and while you’re at it, a transceiver for the 70cm ham band?
As we touched on above, the purpose of any firmware update is to make a change to the existing software in some way. But what, exactly, any specific firmware update accomplishes depends on the context and the specific firmware version. Smartphones (like iOS and Android), digital camera manufacturers provide the same functionalities about firmware updating the devices. Firmware is permanently embedded into a device’s read-only memory to enable hardware-level control and security. Other electronic devices may not look like a computer, but they still have an embedded system such as a microcontroller inside, with a program telling them what to do.
