Large size heated bed for printing ABS Could anyone recommend a large size (12"x12") heated bed that reaches 110C for printing with ABS plastic? I have built my own 15"x12" heated bed that is only good for PLA printing at 60C. It has hot zones and cold zones that causes printing problems with large prints. https://reprap.org/forum/read.php?1,181204,181204#msg-181204 Sun, 13 Sep 2026 17:16:17 -0400 Phorum 5.2.23 https://reprap.org/forum/read.php?1,181204,181925#msg-181925 Re: Large size heated bed for printing ABS https://reprap.org/forum/read.php?1,181204,181925#msg-181925 davew_tx General Mon, 04 Feb 2013 09:46:44 -0500 https://reprap.org/forum/read.php?1,181204,181793#msg-181793 Re: Large size heated bed for printing ABS https://reprap.org/forum/read.php?1,181204,181793#msg-181793 I assumed that I need to either use a customized signal from ramps or change settings (in Marlin) to lower current in signal to the relay from ramps.]]> peddiparth General Sun, 03 Feb 2013 20:38:45 -0500 https://reprap.org/forum/read.php?1,181204,181465#msg-181465 Re: Large size heated bed for printing ABS https://reprap.org/forum/read.php?1,181204,181465#msg-181465
those rubber heaters are nice. come with adhesive also.
cheaper than 2 PCB boards.

If you have an aluminum plate, the heat will spread out.
The heat won't spread if the heater is on glass.

If you can post a circuit diagram, that will be very helpful.]]> peddiparth General Sat, 02 Feb 2013 12:31:53 -0500 https://reprap.org/forum/read.php?1,181204,181345#msg-181345 Re: Large size heated bed for printing ABS https://reprap.org/forum/read.php?1,181204,181345#msg-181345 store.qu-bd.com]

Could you please elaborate on how you connect your automotive relay to the input from Ramps 1.4 and the 12V 30A power supply?]]> peddiparth General Fri, 01 Feb 2013 20:43:11 -0500 https://reprap.org/forum/read.php?1,181204,181222#msg-181222 Re: Large size heated bed for printing ABS https://reprap.org/forum/read.php?1,181204,181222#msg-181222
