Hello all,

I regularly have problems with the pickit-3.(MPlab X IPE v 5.45) .

  Because it happens less often when I first start up my PC, connect the 
pickit to the PIC and put voltage on it and only then connect the USB 
cable, this is my base.

  Despite this, I get often  messages that the voltage is insufficient, the 
PIC is not the right type or a wrong feedback occurs during programming. 
This can almost always be solved by restarting MPlab, or by first 
performing a read or an erase.

Lately I've been working with 3.3V. Now I had a program under 3.3V and that 
didn't work at all after programming without errors. After I erased the PIC 
separately below 5 V, the program works again.

I have two clones. One suddenly doesn't work at all under 3.3 V, but with 
the Pickit_minus (with modified firmware) on 5V.

Can anyone tell me where to look for the cause of all this?

regards

Hans
