support fan (using the own) for cooling tmc drivers by joshuruiz

Last crawled date: 3 years ago

I have designed this support using the same chiron fan to specifically cool TMC drivers that are very sensitive to the lack of adequate ventilation for them.
In order for it to be installed, the cover must be removed and left without it all the time.
It will be necessary to use some kind of feet dampener for the printer to prevent it from hitting the groun. i use this:

My tmc2xxx VREF at 87% of margin
X = 1.044V
Y = 1.175V
Nema 17 Motor power calculated was
X AXIS = 1.2A
Y AXIS = 1.35A
i used this vref calculator:https://mvo46.csb.app/
Original A4988 drivers Vref are:
X=0.837V
Y=0.944V
Z1=0.915V
E0=0.837V
Z2=0.903V
he diseñado este soporte de ventilador (el mismo que trae la chiron) para específicamente refrigerar los drivers TMC que son muy sensibles a la falta de aireación adecuada para ellos.
Para que se pueda instalar hay que retirar la cobertura y dejarla sin ella todo el rato.
Será necesario usar algún tipo de alza para la impresora para evitar que choque contra el suelo.https://www.thingiverse.com/thing:3225296
