Upgraded Extruder X Carriage for Type A Machines S

This upgrade allows users of the Type A Machines Series 1 or U-T-O-M printers to utilize a QU-BD or MK7 clone extruder from various suppliers. The primary benefit of this modification is enhanced support for all-metal hot ends, enabling the printing of high-temperature materials such as nylon. Compared to other available options that involve swapping out the hot end only, this upgrade provides the flexibility to install an entire aftermarket extruder and is also compatible with an upcoming dual extruder model.
