Hey #3dprinting community!
I'm running a sturdy #corexy printer I've build myself back in 2018. Currently, I'm thinking about replacing it. Since 2018, the market evolved and seems to come up with affordable quality builds, quality of life features, new capabilities (multicolor ...) and the need for less tinkering (I've kids now 😉). It seems like the more "integrated" systems don't play nice with my beloved #octoprint . Is it getting less relevant? What do you think?

another model you asked me for at SMRRF is the Prusa Core One piggy bank, so I uploaded it to @printablescom and you can start printing it 😉👌

Alrighty.
After dicking with #Klipper for two days, there's something wrong with the kinematics.
Being a Hybrid #CoreXY, my kinematics have a lot less people using them than a run of the mill CoreXY.
Hybrid CoreXY means that two steppers have to work together to make what might be a simple, lateral Y- toolhead move.
I am not an expert at #Klipper by any means, but I've noticed a couple instances when this seems to be true.
There's a small bump at homing (which could also be Klipper backing off, in case it was already flush with the sensor) but there is also an example near 0,0 when clicking the button to move Y, only moves the X stepper when it should move both.
This shouldn't happen. It needs to operate BOTH the X and Y steppers together to make that move. Even if it cannot move one (e.g. it's at the limit), it should then abort the move on the OTHER stepper. It should never move ONLY one when both are required.
So; After two days, it's back to #Marlin.
I just added up the price of making my own #CoreXY #3Dprinter.
it wasn't too bad, then I noticed that all the metal work had been deselected, once I added that back (spurt coffee.gif).
I'll just carry on with my #Ender3
Forgot to add a way to tension the belts, so I had to redesign the part. 😅

A Review Of The Two Trees SK1
My journey into 3D printing started ten years ago with a Prusa clone I built from a kit, and has moved forward in fits and starts. Last year I decided to invest more into it, and now things have escalated yet again–for I have spent the past month testing the Two Trees SK1, a solid CoreXY machine tha(...)

Why is the belt moving up and down?
This is generally due to 4 things:
- Angular misalignment of the pulleys/idlers
- Parallel misalignment of the pulleys/idlers
- Belt quality, wear and type
- Pulleys/idlers quality and wear
It is also good to know that long belts have the teeth cut at a very small angle which could also increase this phenomena.

Today, it's hard to find a 3D printer motion system that isn't capable of fast printing with both light or heavy extruders. I wish the motion type would stop being an important selling/marketing point.
Focusing on the quality and testing of the design itself is a more important aspect.
For example, thermal expansion, scalability, ease of building, hardware quality, low maintenance could impact a lot more than the motion system itself.
Working on yet another spare parts 3D-printer. 🙃
CoreXY on the Pi Pico https://hackaday.com/2023/12/28/corexy-on-the-pi-pico/ #RobotsHacks #plotter #CoreXY #rp2040
Now that I have a printer capable of printing ABS and an #ender5plus that needs some work, I think I'll be doing the mercury one conversion to #corexy and the hydra bed conversion.
Hopefully this will give me a good, reasonably fast large format printer.

Seeing the performance difference makes all the designing work feel worth it
