Know before you buy
No, this motor and mainboard set is specifically engineered for the MYRIWELL RP-300A. It is not compatible with other models in the MYRIWELL lineup.
This set covers the core mechanical and electronic components responsible for extrusion and control. If your pen has stopped feeding filament or is unresponsive, replacing these parts typically resolves the issue.
You will need basic tools, such as a small screwdriver, to open the pen casing and swap the components. No specialized electronic soldering equipment is required for a standard replacement.
If your pen is failing to heat up, showing erratic LED behavior, or failing to respond to button inputs, the mainboard is likely the culprit. If the motor is making noise but the filament isn't moving, the motor itself may be the issue.
Yes, because these are direct replacement parts designed for the RP-300A, installing them will restore the pen to its factory-standard operation and reliability.
