Hi Scott, I'm glad you took the plunge. Also glad you like the mill . I presume a GFCI (ground fault current interrupter) is similar to our "earth leakage circuit breaker". Mine runs no problem, though it is possible my ELCB doesn't work. Maybe there are some electrical differences in the mill (mine is made for 240V, while I guess yours is 110V). I did some measurements of my head tramming and it did need adjustment. Mine was out 0.15mm (0.006") in 450mm (18"). I used some shim brass to true it up. Was going to write it up at some stage. It is now down at under 0.002" in 450mm (my dial indicator is imperial). Of course, with time and use it may move a little. My spindle run out measured 0.1mm (0.004"), but I want to remeasure. It occurs to me that I have no idea how accurate my collet chuck and collets are. I'll remeasure directly on the spindle, and with another chuck, and maybe with a MT3 "shaft" (what is such a thing called - an arbor maybe). My guard did beep, it also got in the way and made the machine useless. Yes, the knob would be preferred, as after switching off you need to reset the speed - can take a while if you are picky about the exact number, as I can be! You also have a different colour scheme. I do think power feed in the Z axis is warranted too. What is backlash on the X and Y handles like? James.
