<div dir="ltr"><div><br>tl;dr, the 2 3dp machines currently at noisebridge are updated to the sailfish v7.8 and SD card only for now. fat32 works fine and gcode must be converted to s3g files. <br><br><br>Last night I used an avr programmer to update the firmwares on the 3dp clone mini army at noisebridge -- they are
now running the latest version of sailfish, v7.8 <br></div><a href="https://github.com/noisebridge/Sailfish-MightyBoardFirmware">https://github.com/noisebridge/Sailfish-MightyBoardFirmware</a><br><div><div><br>Both boards are [merciless, soul crushing, think of the children] faithful clones, and both use originally as-designed stock atmega1280 chips. Desoldering the atmega1280 and replacing with a atmega2560 could provide an upgrade path for a bit more 'fun' plastic junk printing machine, which I'm open to discussing the merits of doing.<br><br>In any case, I still need a good firmware for the usb to serial chip (atmega8u2) so that computers with os x/linux/window & octoprint (with gpx plugin) *or* any alternative controller software (printrun, etc) can perform direct control of the machines. <br><br>The LUFA project was used for this by Arduino folks, and modified by M******t to run at different baud rates in order to prevent in-print resets when reconnecting to monitor machine status. Little remains of all that junk, no m******t wiki or docs beyond github and dead links everywhere, so in the long run it's best to get back to LUFA or something licensed to survice and mostly unaffiliated with money grubbing ambitions. Besides, the sailfish project is just saving hex files to github without a firmware sources or a build setup for this usb to serial IC[*]. When I tried the stock hex files, they didn't work as expected in any
case, so long story short, until this fix, these machines are SD card
