How do You use the pwm control? Is it included in the firmware of either you or dc42? I assume it Needs a dedicated pin. Same for the rpm feedback, supported?Quote

... or with 4-pin PWM fans to adjust the speed on-the-fly It seems to be quite difficult to source them directly from the UK though.

Dear All,
It has probably been covered many times here - but, it is worth posting it again! I accidentally broke one of the vanes on my hot end cooling fans yesterday (don't ask...). I went out to Maplins this morning and bought their 40mm (10mm thick - N48QT) low noise fan and fitted it. The fan is clearly pushing less air, but the temperature measurements of the heat sink are stable at 45 degrees (which I think it OK). The difference is that the Ormerod is now very quiet. It is a vast improvement! If you are suffering with a noisy fan there are solutions available.
Greetings,
Christof
