[youtu.be]. I want to make a 3d printer exactly like this but i couldn't find anything else on it, just this YouTube video. Can anyone help me to configure marlin to allow for this type of movement.

Do you have something? I'm trying same cinematics with SKR2 and RRF but there is no way to control it...

It looks to me that the kinematics is identical to a normal polar printer, in which case the standard builds of RepRapFirmware can drive it.

Large delta printer [miscsolutions.wordpress.com], E3D tool changer, Robotdigg SCARA printer, Crane Quad and Ormerod

Disclosure: I design Duet electronics and work on RepRapFirmware, [duet3d.com].

I runned RRF with my config in SKR2. (I have 3 external TB6600 drivers connected via STEP/DIR mode and 3 classical EndStops)

After first boot, from two red LEDs, I have left flashing and right on. I connected SKR to Pronterface and I only have some random movements in one of the motors. There is no response to any request.

In parallel, I connect a TTF, but currently it is useless. I only need to control my machine manually via Gcode in pronterface. (without wifi control, but I have ESP32U for the future )
