Accuracy is a complicated topic, and we cannot make a general statement about how accurate the machine is.
For the X-Carve, take a class, or watch the video and take the quiz.
For the 4×8, attend a 1-on-1 help session, where you can get in-person help running the machine. If after the help session you feel comfortable using the machine, and the shop manager or volunteer determines that you have demonstrated sufficient care for the machine to use it safely, you will be signed off. If you are very new to CNC, we recommend learning on the X-Carve.
The X-Carve is free to use.
There is a $5/hr suggested donation to use the 4×8, to support the upkeep of the machine.
