Heated Bed with Cura

Recommended Posts

Hi all,

I work sucessfully with Cura RC2 since some days, thanks to the French community ;)

The PLA works well and I now want to work with ABS. I have bought an heated bed but I don't see parameters to activate and setup it ?

Thanks

That's because there isn't any parameter for it in Cura. But you can enable it in the start and end code.

A simple M190 Sxxx should set the heated bed temperature. Not sure how you build your bed, and where you got it from, as there is no official one from UM yet.

It's an Heated bed for reprap. Actually I make as simple as I can do, I just plug the +/- to the 3rd slot on the motherboard, there is a 1K ohm resistance to the heated bed.

It's just for a test to see if the heated bed works because I don't know how much temperature the heated bed can delivered directly with 20V.

Tomorrow I will take a PC supply to connect it independantly and I will find a way to control the temperature. I will bring an infrared thermometer.

How can you edit the Start and End code in Normal Mode ?

I have a problem with the Expert Mode, the printer won't print. The G-Code is Ok, I launch the print, the windows with "connect" appear. I click on "Connect", the program is connecting to the printer and nothing else. I can setup the temperature but the head printer don't heat.

I saw that you can build a custom firmware with the option "Third extruder temperature sensor", is it possible to take this way to activate the heated bed ?

The printing interface in Cura isn't the best yet. It's better to print from PrintRun, which is also packaged with Cura. (I shouldn't have included it until it was really ready :( )

If you edit the start/end code in normal mode, then it's also changed for simple mode. It's one of the few settings that simple mode does not override. As start/end code is usually very machine specific.

No, the 3th extruder is the 3th extruder (firmware supports up to 3 extruders). The heated bed option is for the 3th heater/temperature sensor connector.

In that case you can leave the heater unconfigured and enable the right pin with the M42 command. If you configure a heated bed it will need a proper temperature sensor.
