yesterday while doing some machining the vf3 at work keept getting the spindle cable fault error.(using 1/2" 4 flute end mill and dream drill) we couldnt even finish running the parts we were working on. on the end mill part of the cycle the machine kept locking up with the spindle cable fault error. (dream drill was second part)we ran some different parts today using an inserted cutter and another 1/2" 4 flute end mill and didnt have any problem at all. the machine in question hasnt had any problems except for having the encoder replaced about 6 mos ago when these errors started but the past few weeks it happens every now and then except for yesterday when we had to just shut the machine down. the machine was manufactured in 2008(RTS date is 6-5-08). we would like to try to keep from calling in the haas tech unless we have to just to try to be cost effective if possible. does anyone have some ideas on what may be wrong?
i had read a previous topic about a vf3 where someone suggested checking the tensioner for the encoder belt but our machine doesnt have a belt on the encoder. other than just replacing parts we have no idea where to proceed.
