Maybe my prev post too long CAN A HEATER ON HOT END GO BAD??

[Bruce19]

dont think heater barrel in hot end the culprit?

[Gambo]

Surely it's not a good idea to do am upgrade until you've got the basic unit working!!!

[Bruce19]

Remember good/stock resistance should be 19 ohms Mine reads 0 ohms

[Gambo]

Sorry I missed that the resistance of a 50 watt Heater at 24 volts should be about 2 and a bit ohms cold and twice that at ,12volts. If it reads 0 ohms hot the PSU should shut down. Did you measure the resistance hot or cold??.

[Gambo]

Sorry I got that all wrong I should have said 12 ohms at 24 volts or a current of 2 amps and 3'ohms at 12 volts must be getting old a silly mistake.

[Bruce19]

I did when it is not hot the printer is off

[Gambo]

Did you also disconnect the heater from the power supply ?

[Bruce19]

YES The 2 wires were disconnected
