Hi,

I have a 2000 Fadal 4020 with the standard Fadal MP CNC legacy control that has been acting up lately. The control is running a lot slower than usual when switching from different modes. For example going from Manual to Auto the screen goes blank for several seconds and then partially loads and after a few more seconds finishes loading. The slow processing is also evident in a tapping cycle. The spindle comes down getting ready to tap and then just stops for several seconds, taps the hole, retracts and sits again for several seconds before moving to the next hole. Just wondering if anyone has any ideas on what might be causing this. I have another 4020 that I could swap parts with to troubleshoot if necessary.

Thanks,
Domenic
