We have a Snapmaker A350 that, at the time the problem started, wasn’t even a year old. The problem is that the nozzle will not stay hot enough to melt the filament even though the software says it’s at the correct temperature. For example, we set the nozzle temp to 200C in the little Android inte…

What is a bench calibrated temp sensor gun? I didn’t have any issues, but when running too fast too much. It can’t keep up with temperatures. Maybe update the firmware and use new 109 code params. to see if it helps?

We use a Hikmicro B20 thermal camera when we need to see how hot something is (or isn’t) getting. Check out the comparison between what the B20 says the nozzle temp is (151.7C) and what the A350 interface says it is (205C). [Nozzle Temp Differences] After leaving the A350 turned off for a couple…

Is your hotend connector correctly connected? (clicked in and have all pins the same lenght? - There are 4 Pins) Maybe add some thermal grease to the thermistor for better thermal conduction. Why do you print not with more temperature? What filament are you printing? As workaround, does printing…

I assume you’re referring to the main cable the plugs into the connector at the top of the print module. If yes, then yes, we make sure it gets inserted securely. It doesn’t click though - just pushes in and stops. I checked and all pins are the same length except for one (circled in blue) of the…

Do you still have the spare hot end? If so, can you measure the thermistor resistance on both at ambient and same temperature?

By “spare hot end” do you mean the nozzle itself or a large assembly? I’m not quite following what you’re asking me to measure, or how. How would I measure the resistance of the thermistor? What do you mean by “ambient and same temperature”? Thanks

Did you take a close look at the hotend to see if the thermistor is actually in it? Also, check the wires going to the heater. This is where the majority of issues lie. If the thermistor has popped out, reroute the wiring to ensure that it stays in. Be extremely careful though, as the thermistor…

This is normal because the temp displayed on the screen is the temp of the thermistor, not the nozzle tip. This is why each machine needs to individually calibrate temp for the filaments. That is the nature of thermodynamics and thermal conductivity.

CNC-Maker - The thermistor was inserted into the hot end as it should have been. I removed it to take these two pictures. See anything amiss or is that how it’s supposed to look? Mxbrnr - The thermistor is only a couple of centimeters from the nozzle tip and of course is inserted into the same al…
