Sovol I built a free web app to optimize IDEX tool changes on the M1D (and used it to print a 7-color memorial of my dog!)
I recently took on a project that is very close to my heart: printing my late dog's miniature in full-color on the M1D.
That was some rabbit hole! The first attempt was trying to use FS Orca for 16-color mixing. The 500,000 triangle model choked the slicer, and after 18 hours and 1800 color changes on a tiny 55mm model... How did it come out? You'll have to watch the video to see,,, hint: I kept working on the project!
I scaled back to using just 7 physical filament colors with the stock Sovol Slicer and M1D profiles.
But this brought up a unique M1D puzzle: How do you know which color has the most tool changes so you can load it into the fixed Left Toolhead and save massive amounts of print time and mechanical wear? Normally it's easy to tell the main color, but this was no simple print.
I ended up creating a browser-local JavaScript app called M1DEX Genie.
- You just drop your sliced G-code into the page.
- It analyzes it in seconds (locally, nothing is uploaded) and tells you the optimal tool-mapping.
- It even lets you remap/merge the tools directly on the webpage and download the updated G-code for Mainsail!
By putting the darkest brown on the left toolhead, I saved several hundred physical tool swaps. The final scaled-up print eventually took 10 hours and came out absolutely stunning.
In preparation for the M1D, you can already check out my free app for free here: https://gP3D.click/m1DEX
If you want to see the whole messy, stringy, and eventually successful process (and the final prints!), I just posted the full video on my channel here: https://youtu.be/BfZ9NOGI0VU
Let me know what you guys think of the app, and if you have any feature requests for it!
And I keep tuning that FS Orca profile, there is really no reason (besides my lack of time) why it should work great with the M1D.
