The electronics (stepper drivers and unshielded wiring mainly) are substandard, but you know... just have a play.

You may get missed steps but if you don't leave it unattended the worst you'll get is some wasted material. Best start with cheap wood anyway, so no big deal.

I had a Gecko already that I spotted cheap on eBay. Plenty of other good options out there though. My machine was secondhand and definitely missing steps. I might upgrade to a 48v supply but the 24v seems OK for now.

If you need any 2 and 4 core shielded cable for the steppers and limit switches let me know. I ended up buying 100ft reels of both as I couldn't find reasonable stuff in shorter lengths. I'm also using 3 core 1mm Belden CF for the spindle and that seems fine.
