Hey,
I have CNC Milling and lathe machine installed here in my uni lab and i have encountered some issue. following are the details

first i worked on lathe machine while controlling through computer it works fine with following results.

set the machine to auto
then set start cycle on

LSK command shows up on machine and after then it works fine to control with the PC

but while working with Milling

1) Auto command doesnt light up
2)Start cycle doesnt light up after that
and it does not download program it keeps showing that its downloading but it doesnt in the end
also LSK Command is missing

but in above problems it does accept open vice and close vice through computer.

Getting deeply into its history we have recently replace its spindle drive card from official denford centre as previously its spindle stopped working. after the replacement spindle is working fine now.

I hope i get the reply soon
