That's interesting.  I wonder could that account for hotend having trouble getting heat into them. If the current transfer is interrupted or interfered with due to heat expansion or a contact problem that could affect the temperature the hotend is able to generate

its possible, but my opinion unlikely. the spring holding it all together has some serious tension in it. but always possible

i have taken my hotend fully apart, verified the plate position is identical to the picture. the hotend itsself is the current transfer to the second ceramic heater plate. i can post pictures if needed.
Thank you. I'll try to make out the hotend and clean the contacts

have you tried a higher amp power supply? might not be giving enough power to the unit.

I'm using a new 7Amp power supply instead of the orginal 3amp, but the hero is still having problem to reach 210°C.
Any tips what could be wrong?

I'm using a power supply of 24v 9A and the heating up to 245 degrees

the power of 24v only is for the hotend.

I could not solve the problem with heating. I put the hot end  J7.
 It heat up with a standard power supply

DO NOT TRUST the 101Hero temperature indication!  It reads about 15C high in my printer.

Always do a customized temperature calibration tower for every filament spool, and be sure it covers the full range from "over-cooked" to "under-extruded".
