    Thank you. This machine was made as hobby, for my shop. i was made it about 6 month with including time for study and experiments with best mix for me. And this one compare all my expectations - really rigid frame and heavy. Base net weight about 80 kg gantry about 60. i was instal stepper temporary but now installed servos. i want do replace all aluminum pats for cast iron and steel and install more powerful spindle. Maximum feed is 7200 mm/min (limited by soft) no need higher. acceleration for tests 5m/s2, but this acceleration made scary cabinet shaking so i decrease it for 2.5m/s2. there is some videos Thank you

    Why did you decide to replace the steppers with servos?
