I'm having the same problem on ezpath lathe
coming back from christmas vacation ,fired up lathe and z dac overflow! read in some threads to swap servo motors and see if the problem followed the motors, it did not! then swaped out limit switches ,still the same , i guess its a process of ruling things out !
Same problem with Y axis DAC overflow...
We ran into this problem on our BP EZ Trak just the other day so I pulled the Y feed motor off along with the belt and the pulleys and found the two precision thrust bearings at the front of the shaft were completely destroyed... So I ordered new ones and I'm gonna see if it solves the problem...
Re: Same problem with Y axis DAC overflow...
I know this thread is quite old, but I'm struggling with similar problems.
Noted above about 5V short "will fry the L1 on the BMDC", how do I know if my machine has a circuit breaker. If it does, where is it and how do I reset it? My machine is year 2000 Series 1, V2XT. I did briefly short the 5V line and it now reads 0.6V.
Thanks for any help.
