Anyone knows how the Y moves on this type of setup?
Core-xy turned inside out?
^exactly what I was thinking.
a mirror reflection of m commands & g codes.
The versions of this sort of mechanism I’ve seen use a timing belt running from one stepper motor through cogs on the xy, that then move the y stage. This one may route the timing belt out to the end of the Y, and then rely on moving the steppers in synch to keep Y static.
@John_Bump that’s how it works
Looks like a old-time plotter I used in school. You could say it’s missing the Z axis.
Ho2 its made

Mira este link, creo que la teoria es la misma
I would say it´s more like a H-Belt than a CoreXY, because there is only one belt level. CoreXY has two levels of belts.
Basically if you move motors in the same way move one axis, and if you move the motors in opossite way, move the other axis. With any other combination move both axis simultaneously. Sorry for my english
I really thought it could be core XY but never seen it inverse like this
It’s called a T gantry. They’ve been around for years in pick-and-place. Same basic motion principle as HBot or CoreXY.
The rod holding the pen slides in and out of the piece in the middle and the piece in the middle slides between the two thicker ends is what it looks like to me. There is no motor on the pen axis except for the servo for pen tilt sonit must be controlled by one of the two motors on the other axis. I think you already figured out that much though. I think it is the belt in the middle that drives the axis hulding the pen. There seems to be a belt on the right of the thick axis laying horizontally that is probably the one the moves the middle block and attached to the bottom of the middle block.
I don’t know how useful it would be for a 3D Printer - it seems like slop in the bearings and flex in the rods would be amplified. Additionally, the weight of a direct drive extruder might cause even more distortion. The vibration created by quick, short moves could also be exciting.
If you feel like taking a closer look at how the movement works this is a good example.
it is cooool
Anyone can point me to the belt path arraignment for this? Been searching for a while
@cris_luna TX man. Either I’m really bad at googling or u have this under your sleeve.
