Switch on/off heated bed after printing

[fboth 0]

I use UM with the Ulticontroller.

I have a heated bed with an external controller and display. I want to switch it off after printing. To save power and to cool down. How can I do this without connecting a PC to UM?

Thanks Franz

If I understand you well,

// M140 - Set bed target temp as end g-code does not work because it does not control your heated bed.

So the question is :

- can I connect the ulticontroller to my heated bed

- can I make a connection in series between the two "switches".

To cool down quickly, you could use

// M106 - Fan on

// G4 - Dwell S or P

// M107 - Fan of

I am just guessing.

Hi fboth

Look at this http://forum.ultimaker.com/viewtopic.php?f=6&t=1087 post about a suicide switch for the UM. You should be able the plug you HBP into the socket as the UM and switch it off after.

Dear Filipo,

thanks for your reply.

If I could use the heated bed with the Ulticontroller I would do it.

I would connect a Relay, which I have already bought and mounted to the Heta Bed 1 Output and the thermistor to the Heat Bed 1 input.

What do I need to do then in the Software or is everything ready to be used?

I am not an expert in programming the firmware.

Many thanks for your feedback.

Why cannot you connect the heated bed to the um ?

Dear flip

I do not know how to make the firmware seeing temperature end to control heater.

If the frimware would do it and the ulticontroller too, then the hardware is no problem I can do that.

Thanks for your help

Dear all,

finally I got my heated bed working fine. Thanks for your help.

I could make use of Daids firmware setup program and then connect my heated bed.

I use 100k NTC and an extra power supply controlled by a relay connected to the HeatBed output.

Bed temperature is about +/- 3°C close what seems ok.

Now I will make some trials.

Best regards

Franz
