Following with great interest.
I can already tell you that the first version I designed of the 4th axis worked quite well. The arm was printed to heavy and the carriage I used wasn't ideal but it did it's job.
Thanks to this thread i'm very keen on having this on my heavily modified Anycubic Predator.
You mentioned that the first version worked quite well. Have you had any other revisions since?
What challenges did you encounter when designing and implementing the fourth tower?
Got a video of it in action?
In my case, I'm running a zesty nimble remote drive extruder. I'm planning on using a shorter drive cable and have the extruder motor, some-what in the middle, with a gimbal to minimise forces that the cable would exert on the effector. Also, I'll add the berd-air pump to the forth tower to reduce the length of the air tube and reduce the pressure drop that a longer air tube would induce. Perhaps also add the filament spool to the other side to reduce the length of filament to the hot-end. All just ideas at the moment. Will be interesting to see how it turns out in practice.
Anyway, I'm interested in hearing your thoughts.
