standalone heatbed / ABS Vaping station by shawdreamer

Last crawled date: 3 years, 1 month ago

for those who want a heated bed but lack the facilities to do so without modification on their current printer setup (eg- printrite 3d diy printer users)
this design is originally made to give me a second heated bed surface that I can use to Acetone Vaper treat ABS parts away from the actual printers heatbed (alot safer than doing it on the printer HB as I can move the whole setup to somewhere with zero flame sources and better ventilation)
Alternatively as mentioned, the setup can be used to add a heatbed to a non heatbed equipped printer.
The heatbed itself is controlled via a W1209 thermostatic controller board which is capable of taking the HB upto 110°c (ABS levels etc) and is incredibly simple to wire and operate, in addition the controller supplies all required power to the HB from its own power source (a low spec ATX PSU will suffice aslong as it can supply 12amp+) so in the case of the Printrite theres no need for upgrading the power supply or messing with any of the interior connections (which given how delicate the mainboard is in a PR, is a definate bonus)
the controller itself can be happily positioned where ever you chose but you must bare in mind that the printers software will have no control over the heatbed atall and you must manually set temps and turn off & on.
The design for the controller housing is not my own but taken from a design I came across on tinkercad, I forget the designers name but it can be easily found on that site so any credit for the design is entirely his own (I never use others designs typically but his has proven an excellent fit and credit were credits due)

Its advisable to use the thermistor its supplied with as the board doesnt seem to like the standard versions used on heatbeds (the uncovered 100k ntc versions), the thermistor capsule can be simply taped to the back of the heatbed and supplies surprisingly accurate readings (measured with both a thermistor running from my Ramps setup aswell as a lazer thermometer)
