I use one daily and have gotten it apart to service it from time to time. I have said a few profanities at Gene Haas for that one. The coolant line comes strait down off the cable jacket and goes into the nozzles, when you come to a stop it dribbles. Sorry but I tried to fix it too but to no avail. Now I just find a favorite position where the dribble doesn't get in the way and put that machine position number in the program.
(Example)
G81 Z-.5 R.1 F15.
G80
G0 Z.1
M5
M9
G53 Z0. Y0. X-6.25
M30

I got away from the usual G91 and G28, the same motion can be done with G53 and keeps me from making a screwup by not having a G90 in the next line.
