support fan (using the own) for cooling tmc drivers

thingiverse

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: https://www.thingiverse.com/thing:3225296 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
