We just received a Explorer X-26 Mill from a customer who wants us to do a machining procedure they can no longer do In- House
The problem is that after figuring out the sequnce of events needed to take place to commence machining it appears that the CNC control thinks the spindle is in low range when it is actually (Has been Started In) and is physically in High
The control indicates low range and the current spindle speed is not even close to the actual
We then get a msg: start spindle in high range to begin run

Where do I start to look for the indicator that tells the control it is in high
Should I be looking at the switch itself ?

I read almost all of the previous posts and could not find a simalar problem
