This is a very well built machine, however be aware that it is also very heavy. The quality of the frame, guide rails and controller are also machined and assembled very good. Unit arrived mostly together other than minor components and the large gantry attachment that was also very heavy but again well built. The only mediocre component is the dust collector that I would recommend to possibly upgrade it just because it is a little flimsy. Sales contact Tracy was also very good and professional. I HIGHLY RECOMMEND THIS MANUFACTURER.
