@o_lampe Yeah that’s kinda what I was thinking. My only concern is that it should theoretically create a torque around the center point, so it might try really hard to fall over.

@shaunppl There is definitely a possibility of issues like that. The reason I’m building this at such a small scale is because it’s purely for proof of concept purposes - to test if that will be an issue present.

@dc42 Good to know!
If I just take the approach of specifying the additional motors and inverting them, along with using m579 to set the scale to 50%, would there be issues with delta calibration/homing of the two gantries? Or since they’re identical would I only need to calibrate one side.
Thanks!

@dc42 Very interesting, thank you. Can I treat 3 extra towers as an additional gantry?

@o_lampe Yeah, that’s what I meant by rotation distance. Sorry, I get all the different names between firmwares mixed up.

@o_lampe thank you for your response!
I mean, there’s no way to know for sure until I test it. But, I didn’t want to create the same delta as everyone else. It’s also cooler in my opinion even if it performs worse.
Wouldn’t I also need to figure out a method to split all the movements between the two sides? I mean, I was kinda thinking to just halve the rotation distance, but that feels like a bit of a cheating solution.

@o_lampe A quantum delta is like a delta, but the bed moves.
The bed is very light, lighter than the toolhead actually, as it’s only 65mm in diameter. It’s a fairly small proof of concept printer.
Currently I am planning on using endstops for the gantries.
The benefit here is that theoretically, each side only needs to go half the target speed, so overall high speed printing will be much easier to accomplish.
That’s what I’m building this for - to test it.
It also just looks cool.

Hi there! First time posting here. I am currently in the process of designing (well finishing designing) and soon will be building a delta/quantum delta hybrid machine. Basically, both the hotend and bed move independently with delta kinematics, with separate motors and belts. My question is - what would be the best way to implement this kinematics-wise? Basically, I need each side to do half of the moves in opposite directions. I would ideally like to retain individual functionality/control of the two delta gantries.
Thanks!
