Prusa Core One HT – Finally, it's done!  

RE: Prusa Core One HT – Finally, it's done!

Glad it worked with the idler arm, i always try to keep mods to the bare minimum 🙂

Hello Cédric.

Yes, that's true. I completely lost sight of the modified idler. I had only seen that it would be nicer to place the bend of the filament around the extruder drive. But it works now 😉

Printed right out of the box on prusa nylon settings, have you modified anything except temps, i never put effort into calibration of the print parameters?

I actually only adjusted the temperatures. Everything else was taken from the “Prusament PC Blend CF” profile.The filament is now dry, and I can print this hook from CNC Kitchen to see what it can withstand. I think this will be the first good practical test for my Prusa C1 HT.

Would be nice if you could print several standing hooks from 290-330 degrees and try to load it heavy to see if there is a measurable difference in what it can take. But maybe its more practical to use a smaller hook, depending on what equipment you have, its not that easy to find so many weights 🙂

I will test it 😉

Hello, everyone.

I hope I haven't forgotten anything and that everything works with the GitHub fork.

This was the first time I uploaded something like this. The AI was a great help.

If anyone would like to test it, here is the link:

https://github.com/jandslay/Prusa-Firmware-Buddy-Core-One-HT450

All further tests with PPA-CF and PPS are still to come. I have another big project running in parallel with the Prusa XL, and the little Core One usually has to take a back seat 😉

Hello everyone.

I had some time again to continue working on my Prusa Core One HT450.

I implemented a Volcano mod today. I wanted to redesign the fan shroud so that I could use the longer Volcano heating block for other filaments as well. Today, I had the idea of simply shortening the block.

No sooner said than done. Now I can continue to use the original Prusa nozzles and there is enough space compared to the original Prusa heating block for the PT1000 sensor and the heating element plus cable.

Currently, a Benchy is printing with Siraya Tec PPA-CF, and tomorrow the fan cowling will be made from PPA-CF instead of PCCF.

And then finally, the hook I wanted to print plus the heat shield will be added.
