Re: Switching heat bed

Hello,

I have about the same problem with my rapman 3.2
I'm using I/O 1 & 2 for both extruders.
I just got me an MK3 ALU Heatbed, but i'm not sure how to connect it.

When configuring printer settings in Axon software, the RapMan 3.2 offers only choice for 2 extruders.
To get the 3rd extruder in the printer options, i need to choose a diff printer, which has not the same printzone as mine.
So how did you get it to work? Is the I/O active even when RapMan 3.1 or 3.2 is chosen in the printer options?

I do have a spare driver to connect to I/O 3. I also got a 100kOhm thermistor (MGB18-100K) and a MOSFET (IRFZ244N).
To power the bed i have a PSU of a computer, +12VDC / 60W output.

Could you please assist me on getting this to work?
Do you have a schematic on how to connect the whole thing?

Any help will be much appreciated.

Greetings
