I have an old Teledyne Gurley Patfinder 50/ Pointfinder DRO on a Bridgeport, and it has worked flawlessly for decades. This is the first time I have operated the mill in cold temps (ambient temp above freezing, but only by a few degrees ~35°F), and there is some serious skipping during use.
At first, this only happened on the x-axis, so I cleaned the glass scale and all was good. In hindsight, this could be due to the fact that the scale and encoder were warmed up while I serviced it. The issue actually appears on both axes.
Just for fun, I zeroed out the x-axis, and left it on overnight, and it jumped 57" (it was probably below freezing in the shop that night).
Has anybody else experienced something like this?
Thanks.
