I posted a thread earlier about a v2xt that ran at max rpm all the time. I finally got a chance to play with it some more this morning, and I found that when I turn the spindle on with the s_t_m function, no air comes out of the lines for the speed changer. Is there suppose to be air moving up there? Yes, I have the air plugged in. I have manuals for this machine, but I havn't found anything on this problem. some help would be greatly appreciated. thanks.
