Heated Bed Kit
The heated printbed is very helpful against the warping and deforming of bigger objects while printing. If longer object cool down unevenly, stress gets introduced into the object and it might deform or loose contact with the printbed. With this heatedbed your objects are kept warmer while printing and this reduces the chance for this problems. Ideal temperatures of the printbed are around 50°C for PLA and around 110°C for ABS.
The kit comes with a 215 mm x 215 mm pcb which is used as heating source, a 225 mm x 225 mm x 3mm aluminium plate to spread the heat evenly and provide a flat printing surface, a 100k thermistor to measure the heat and with enough Kapton Tape to assemble the heated bed and cover the printbed with it.
Please notice this heated bed needs up to 11A and you need a powersupply for it which is powerful enough at 12V. If you use RAMPS electronics, you need to connect an aditional powersupply to the 12V/11A screw terminals.
Using you soldering iron, you sould now connect the thermistor the contacts in the middle of the printbed. And also solder wires to pads on the side of the pcb. Make sure to use thick enough cables on the + and - contacts.
After soldering secure the thermistor and the cables with some Kapton tape. Now you can mount the heated bed onto your 3D printer. Make sure to install the pcb with the text pointing downwards and the aluminium plate above it with the covered side up.
Finally remove the covering of the aluminium plate and carefully cover the plate with the Tape of your choice. For ABS Kapton tape is ideal. Now you only need to correctly connect the wires to your electronic and its ready for printing.
