Extruder heater not heating at expected rate

I've had 1 successful print out of this printer now it's throwing up errors like this about 6-10 layers into a print, is there something I'm doing wrong? I've tried to read the klipper log but all it tells me is that the temperature goes down. Log and screenshot of problem attached.

What hotend do you have? Did you PID tune with the fan on 100%?

If that doesn't work you might want to check the heater isn't loose. Air is an insulator and if its not clamped properly it won't work as well. Im not familiar with the Mosquito so I don't know if this issue can even occur, but its worth checking.

6-10 layers... This might also be the part cooler that turns on at this point. Using a silicone sock will help there

Oof. Those are known to be affected by the fans a lot because of the huge heater block and shape. Hopefully you at least have a silicone sock on it. But better would be to get a different hotend that isn't affected by part cooling fans so much

I also don't have a silicone sock🤦 I shall make the investment if pid tuning doesn't help

or - just saying - return it while you can and get a better hotend design

Is it really that bad a design?

yeah - I have a clone of it and they fixed some of the issues. But in general there are much better designs

yeah - I would contact RR and tell them how mosquito is a poor choice to have in the store. I really wish they would stop offering it as an option for new builds

I had this exact issue with a magnum and a 4028 fan. I had to limit the fan to 40% max otherwise I would get these as soon as the fan turned on.

Sorry to revive this but I am running into this issue now with a Mosquito, what is a better choice of hotend over the mosquito?
