Hello all. I just had a 2015 Fadal 4020B (Series 1 Taiwan Built VMC) I was working on some items to do with the coolant tank on the floor and upon checking the locknuts for the jackscrews used in leveling the machine I discovered they were all left loose by the installation technician.I'm not a CNC tech but have many years as a mechanic/machinist on a variety of equioment. The first thing that strikes me is that this is wrong and there would be a possibility over time (and heavy interupted cutting) that the jackscrews may back off putting the machine in an out of level along with getting uneven weight distribution over the 6 jackscrews. Any techs or owners have any opinion and experience with this scituation?? Thanks in advance for all your comments......G
