Re: Sherline controller thermal protection

Boy, must be my day to play safety leader :-)

Tony,

Have you considered the ALTERNATIVE to the motor shutting off due to
thermal overload?!?!

At best, a burned out motor (which will STILL wreck your part and/or
machine!).

At worst, a fire as the increased temperature sets off some oil or
solvent vapor... Or just the motor itself catching fire...

IT DOES HAPPEN! That thermal overload is there for a reason!

Hope this helps.

P.S. On the other hand, if the thermal protection could be
parallel'ed to the CNC's emergency stop input, so that if the motor
stops the cnc stops also... :-)
