Re: Hotend slow heating - 12 years ago
QuoteCefiar If you measure +12V on one pin to ground when the heater is on, but don't measure 12V across the hot end (from one pin on D10 to the other) while on This is the case. I tried to test FET for D10. I wanted to see if there is voltage at the gate of the FET. As you said in your (Cefiar) post here . I measured the voltage at R13 and ground (-V of power supply), when the hot end is on. Andby Memphis - RAMPS Electronics
Hotend slow heating - 12 years ago
The hotend heats too slow. It takes appropx 20 min to reach 200 deg. When I press the heater on button, the heater LED on the Ramps illuminate. I measured the voltage between the D10 POSITIVE terminal and supply GROUND (NEGATIVE) from my power supply (PS). I get 12v even when the hotend is not being called for as long as the PS is on. I also measured the voltage between the pin on the MOSFET furtby Memphis - RAMPS Electronics
