Can someone please direct me to some links to get me started with using the mpcnc. I have it built and ready to go however I can not seem to find any good tutorial videos on how to get it started making its first cuts. The videos i have found really arent all that good. i wanna start with making some signs and yes i know to first use with the pen but even with that i can not find videos on how to actually get it started with lets say estlcam for example
