Reviving my (own) old topic. I bought a X-Soldering pro at Aliexpress and asked a friend to buy original JBC tips in USA. When both arrived I tested the station and it didn't work: probes where recognized while the handle was at the base
but as soon as I take them out it tries to heat up but fails:
If I return the handle to the base it doesn't return to work:
Only way to make the station recognize the probes again is power cycling. The most incredible part is that a few days later I tried again and the station worked wonderfully.... and now it stopped working again, same syntoms. Any ideas? I think it may be noise injected from ground pin... will disconnect it and see wha happens.
