    Only 25%? Ours went up by 60%. Ok, we bought another Mill3D license last year but still I'd like to hear some real arguments. 2020 is definitely not that great and the core problems still persist.

    I worked with an SL-250 for four years and it was an excellent machine. Very fast and accurate, although it got abused every now and then it always kept its precision (less than 0.0004" repeatibility...

    Mill3D is definitely the minimum package I'd have. Even if you don't do 3D you would get a "Dynamic 2D" toolpath that allows you to generate dynamic toolpaths which utilize the full cutting length of...

    Hi,

    Is it just my machine or does anyone else have G49 plunge into negative Z direction so far as the length of the tool, if G43 is active? That's why I always put G28 G91 Z0 first.
