hc300tc hypercube 300 tool changer

thingiverse

Hi and thanks for visiting. I'm excited to show off my pride and joy, a tool changer I've designed specifically for the community where I've been following along. The frame is based on a standard HC300, but I've completely reworked the X and Y axes, and I'm currently using the dual Z axis from hashtagdavi - hopefully, I'll make it triple in no time. The tool changer concept is inspired by the E3D tool changer plate, but I've redesigned it to fit my preferences. Although it still uses a servo motor, it's proven reliable for me; eventually, I plan to switch to a stepper motor. The X and Y axes feature MGN15H rails, while the Z axis relies on 12mm smooth rods (I'm using LM12LUU holders that I've also designed). For my print heads, I use E3D V6 hotends, and for my extruders, BMG clones - these are connected to a Duet 2 WiFi board, which, in conjunction with a Duex5, allows me to control up to 10 stepper drivers. To maximize heatbed performance, the system runs on 24V. As you may notice, this project is still a work in progress; I'll be updating and uploading new parts as they become available. Right now, I'm focusing on making improvements. Regarding the servo motor, I've replaced the original lock pin with a metal one to prevent it from breaking - it's a constant issue for me.
