Remote labs can provide authentic and self-paced learning experiences and help to overcome barriers to learning such as high equipment cost and limited lab time.. The paper describes the development of a remotely accessible Ultimaker 3D printer and learning materials for learning CNC programming to enable remote learning. A 3D printer is similar to a 3-axis CNC machine in having X, Y, and Z axes, but is more affordable and versatile. Users can either run an entire CNC program as a job or run a segment of code at a time. The materials were evaluated by students during the lab time. Students responded positively overall to the remote access tool and to seeing the real-time response of the printer to the G-code; and expressed a desire for more time to play with the system. Student suggestions included providing a better view of the position of the tool tip. Future directions include splitting the program into subroutines so that a sub-routine will be executed only when requested, rather than loading the entire program at the beginning. We will also provide a better view of the 3D rendering model using multiple images from webcams positioned at different locations in the machine work envelope.
