I swapped out the drive motors on my CNC from steppers to servos; in this post, I go into the details of all the troubleshooting I’ve done over the months before making this costly upgrade. Though it is not necessarily justified for everyone, the improvements I’ve seen in accuracy and performance have made it worthwhile for me, providing the foundation to tackle much more challenging jobs (and to lower my stress level when doing even simple jobs).

Putting together a custom-built CNC is far more than just building the frame. Over two months, loads of wiring, custom metal, and loads of testing and (re)configuration and learning later, I finally have a functional 4’ x 3’ CNC, with an auto-tool changer, 4-axis and 5-axis capabilities, and working dust collection. This post goes into the process of setting it all up, with loads of pictures and a few tips, tricks, and gotchas for others trying something similar.

In building my own multi-axis 3’ x 5’ CNC, I found key components in Australia, China, Germany, and the United States; in this post, I share the options and the thought process that went into selecting the frame, spindle, motors, controller, and automatic tool changer.

The X-Carve served me well for three years, supporting everything from delicate jewelry box engraving to cutting solid ipe stair treads. However, as more commissions require or can at minimum benefit from the CNC, I increasingly pushed up against its limits. In the first of a three-part series about the process of upgrading this machine, I walk through my requirements for the upgrade and how that maps to the prior limitations of my equipment.
