Excellent precision! 10/10 would recommend
I had trouble with backlash (mechanical looseness) on my WorkBee CNC 1510. After troubleshooting and posting my concern on the forum, I was suggested to check the pulleys. I used loctite to on all my pulleys but I was missing a screw on the Z-axis pulley so I purchase a set of two (I like to have a spare). After installation my 1510 accuracy was dead on. I'm building a robot with my students and need tight tolerances. Thank you Openbuilds for your advice and great customer service.
