How to shutdown Snapmaker 2.0

I couldnt find a shutdown button, like a typical hardware machine.
Seems that the only way is through the power module on-off button, which is a very bad idea?


that’s how you do it


Thanks. Thats quite un-expected, after paying quite a bit for this machine.
The machine and touch-screen controller will be subjected to quite a high breakdown rate, if frequently on and off.

It’s normal for a 3D printer, even a CNC and Laser. There aren’t many out there that I know of that actually have a shutdown option on the screen. Besides, if you were to have a power surge and it were only turned off similar to a computer, not having the PSU switch set to off would actually still allow that surge to come through and damage the machine. Personally I think it should have a shutdown option on the screen which puts the machine into a low power state and then you could turn off the power switch after that, less of a sudden cut off for the machine.

why would that be?

So let’s start with why there is a shutdown option on PCs ( if what you mean by other machines). The reason why you would want a procedure for shutting down rather than power cut has nothing to do with health of some electrical components but the fact that there might be flying IO operation on your hard drive, network etc. Since snapmaker has no such things, keep in mind that any gcode got read and fetch into internal controller memory, so it is read only from that point on and you will have 0 benefits of graceful shutdown.

p.s. to keep electrical (non mechanical) components healthy the best is never to shutdown rather than how you shutdown

It’s 6’s. It depends on how you use it, if you are going to only use it for a short time before stepping away and are not going to come back to it later, then shut it down. If you are going to come back to it later then leave it on. No matter what you do, wear will happen to electrical components whether you leave it on or turn it off. Sudden surge of electrical power wears out components, but so does continuously having it on.

To put it in better terms to understand, If you use it lightly (short lengths of time) with longer gaps of time between uses then power it off. If you use it moderately, short to medium lengths of time then step away and are constantly coming back to it for more use without huge lengths of time between uses then keep it on. Needless to say that heavy use follows the same rule as moderate use.

In the end, heat remains the #1 killer of components, with exception to over voltage.
