Afterwards I was able to compile the project.Īfterwards I uploaded the sketch using the instructions in I’ve browsed the web a bit and got a hint that I should replace all occurrences of fpos_t in all files in the project to filepos_t. When I tried to compile the code in arduino I got the error: SdBaseFile.h:38: error: using typedef-name 'fpos_t' after 'struct'Īs the type was already defined in stdio.h. This came to me as a surprise, as I have installed the Z Axis upgrade, but did not install the LCD upgrade. I already had the arduino software installed on my machine (version 1.8.5), I’ve downloaded theĮxtracted it, and found the folder Marlin - 2560 - LCD. I’ve installed it, readjusted the height, and saw that I need to update the firmware. Once you have a programmer you can use it to install Marlin directly, but we recommend installing a bootloader first, then following the easy instructions above.So I got the k8204 Z Axis upgrade. For more information read the article Installing an Arduino Bootloader. Arduino IDE includes a “Burn Bootloader” function, but a programmer device or spare Arduino is required. A bootloader is required to allow the board to be programmed from the USB port. If nothing seems to work, your board may not have a bootloader installed. Disconnect or quit any host or slicer software ( e.g., PrintRun, Repetier Host, Simplif圓D, Cura, etc.) to release the serial port. If you get “timeout” errors while attempting to flash the board, make sure that no other software is connected with the board.
