I have several guitars hung with them. My favorite model has the wall mount separate from the hanger, which slides on. Most important thing is to print in the correct orientation to handle the stress load.

The updated Fixed-Time Motion scheduler and trajectory planner is blowing away the previous implementation with its smooth and quiet operation. It’s been ages since we just sat and watched the printer in awe, but this is some crazy magic. #RepRap #3DPrinting #OpenSource

Realtime 100x print speed is possible, but only in simulation! Attach the Marlin Simulator to LLDB in VSCode and there's no more fun and exciting way to debug and test your improvements to our small and maximally efficient #OpenSource motion system. #RepRap #3DPrinting #ImgUI

Most people just use Auto Build Marlin in VSCode. You will need to be more comprehensive in setting up your configuration. I was merely pointing out that building Marlin is relatively trivial if you have a good configuration.

The options that were modified allowed the firmware to build for SKR3-EZ. The mftest command is included in the Marlin project and it builds Marlin from the command line. The -a flag tells it to automatically determine the correct target env.

For a test to make sure everything is copacetic I just did this and got a successful build. Of course, various settings would need tweaking, but it works like a charm. The "Auto Build Marlin" tool makes it slightly more convenient.

Indeed, the Ender is often the best choice for an example because it is a reference design. If you have a config created that works for your Ender-3 with SKR-3 EZ please submit it to the project! We rely 100% on the community for these things,

Examples Customizations Β· MarlinFirmware/Configurations@6cc6fda

Change nothing else β€”only the MOTHERBOARDβ€” as a starting point. If it builds and works you can then make your own adjustments. Some examples may override a pin or two so watch out for that. This helpful page shows just the non-default settings in isolation: github.com/MarlinFirmwa...

14.09.2025 14:34 πŸ‘ 0 πŸ” 0 πŸ’¬ 1 πŸ“Œ 0

Build examples are for specific printers, not boards alone. Take an example for the given machine and just change the MOTHERBOARD to whatever you’ve got.

With so many changes in our industry, now is Marlin's critical moment.

Our sponsorship is in steep decline, yet our workload is holding steady.

As we continue support and development we need your help now more than ever!
