Has there been any warping with your duct? Maybe the air isn’t blowing as directly to the parts that need cooled as it did the first print?
I also think that improvements could likely be made to the duct itself, but I lack the design skill to make these improvements reality. Although I would like to look into doing some airflow analysis of this duct to confirm my suspicions that airflow speed, direction, and focus could be improved.
Should I also do a PID tune after adding this fan? I’ll search for the how to on the forum, I just need to know if anyone else has seen a need for it or had any trouble with it.
@brent113 I try to get that damn fan working if I connect it to a powersuply it works, connect to the snapmaker - it starts up and after a few seconds it stops! Cant imgine what Iam doing wrong! Tried with and withpout flyback. The origonal fan is still working when the new one goes down.
Fan1, then try to type M106 into console and see if it turns on full blast
i thought it was not working right but after fiddling around enough i decided it was.
i only say this because there are infact 2 fans in there, and one of them runs full time and one doesnt really run u ntil you tell it to, but might on power up for a moment.
also, you can try it direct to the fan connector to bypass your y splitter to trouble shoot futher
Hi MooseJuice,
I dont know is it fan 1 or 2, but I use the right one cause its spinning up together with the original fan.
but as I said after a few seconds it stops, and a 107 stops the original fan.But another 106 brings only the original fan back to work. It is weird
OK, well I say here is a good trouble shoot temporarily.
Plug the fan into Fan2 and turn the power on, it should run constantly whenver the heated nozzle is on. This is however not the right place to connect it during use, because the correct part cooling fan is fan 1 and fan 2 is a fan to prevent overheating on the board.
if the fan still doesnt run full time with the nozzle on in the Fan 2 port, maybe your cable is not right or a loose pin.
Well, thats good - and you might have everything right, and dont mean to sound like you dont know what you are doing, but just want to be clear about the setup because i had issues getting it going too
There are infact two fans in the head doing different things at different times.
For operation of new blower fan:
Connect Y-Splitter into Fan 1 port of board inside, move existing plug from Fan 1 port to one of the split Y ends, and the new blower fan to the other.
Power up machine and type M106 into console (with capitol M), no other suffixes needed, this will turn FAN 1 on to 100% power.
If this does not work, lets try to instead troubleshoot with this step:
Disconnect the above, and connect the blower fan directly to Fan 2, power up the machine and turn the heated nozzle on. This should enable the blower fan constantly while the heated nozzle is on. You don’t want to keep it like this, but just a troubleshooting step.
If your results differ from this, maybe your y splitter is not correct in some fashion. please share the results of these two scenarios
