Hello all! I'm a MechE who has been working on printers for the last 7 years but have never touched the software/firmware side too much other than some basic post slice G-code modifications. I'm attempting to make firmware for a custom machine with Duet Boards that does more than just print and I know will require me to establish other axis and a lot more than the standard Reprap Wizard does. So... Obviously, a slicer turns models into g-code which is then interpreted by the microcontroller and turned into movements. However, for this custom machine, I of course do not want to modify the g-code every time I use it so can one use ONLY g-code in the firmware setup in the .config files to build out a completely new firmware for a custom machine like I'm trying to do? If not what is the best way to approach this firmware build. Thanks everyone! https://reprap.org/forum/read.php?1,887421,887421#msg-887421 Thu, 08 Oct 2026 22:14:54 -0400 Phorum 5.2.23 https://reprap.org/forum/read.php?1,887421,887457#msg-887457 https://reprap.org/forum/read.php?1,887421,887457#msg-887457
If it's more like the latter, you might want to look at Klipper as an alternative firmware development package.

Might be easier if you want to end up with a graphical front end on a PC that you change with a mouse and keyboard. Also gives you greater choice of controllers. Duets are not cheap.

(My wild ass guess is a custom topping pizza maker but I think that's already a product).]]> DragonFire General Thu, 16 Dec 2021 11:32:40 -0500 https://reprap.org/forum/read.php?1,887421,887422#msg-887422 https://reprap.org/forum/read.php?1,887421,887422#msg-887422
