Always have printer preheated

Recommended Posts

Posted · Always have printer preheated

Hi,

I'd like to always have the printer preheated and ready to go. Is there a place in the settings I can adjust, so that the printer never cools down? I don't like having to wait so long for the printer to get ready. I don't mind the extra power costs associated.

Thanks

You might get this to work at some temp below printing temps, but to stand at idle indefinitely at printing temp will cause the filament to cook itself into a plug in a short period of time.

Are you referring to the heater bed or the nozzles?

As for the nozzles, I would agree with mastory.

As for the bed, I do a preheat while I am doing other things like prepping the buildplate, etc.

What printer do you have?

With Ultimaker 2/2+ you can use the tinkergnome firmware which has this option. So you startup the machine and select this option to heatup (the buildplate)

With Ultimaker 3 you can do this with Cura, assuming your printer is connected on the network, go on the prepare tab and select preheat

In the standard UM2 firmware you can also manually heat the build plate, via "Maintenance > Advanced".

However, if you keep the temp high after print completion, then how are you going to get the models off? They do stick like glued, and you can lift the whole printer by pulling up a tiny model. While after cooling down they come off all by themself, without requiring any force. It may take you more time to get the models off a heated bed, than to wait until it is cooled and simply pick them off. You could speed up cooling by putting a fan in front of the printer, after completion.

And as said above: do not keep the nozzle heated without flow: the filament will burn and clog the nozzle in a few minutes. Printing temp is too close to burning temp.

If you leave the bed heated literally all the time, you will also cook the electronics into an early death.

Pull the electronics cover off the bottom of your printer and take a look - I'll bet you will already find brown spots on the board just from normal use.
