* Peltier Bed - Heating and Cooling
|
||||||
|
*
|
||||||
|
* A Peltier device transfers heat from one side to the other in proportion to the amount of
|
||||||
|
* current flowing through the device and the direction of current flow. So the same device
|
||||||
|
* can both heat and cool.
|
||||||
|
*
|
||||||
|
* When "cooling" in addition to rejecting the heat transferred from the hot side to the cold
|
||||||
|
* side, the dissipated power (voltage * current) must also be rejected. Be sure to set up a
|
||||||
|
* fan that can be powered in sync with the Peltier unit.
|
||||||
|
*
|
||||||
|
* This feature is only set up to run in bang-bang mode because Peltiers don't handle PWM
|
||||||
|
* well without filter circuitry.
|
||||||
|
*
|
||||||
|
* Since existing 3D printers are made to handle relatively high current for the heated bed,
|
||||||
|
* we can use the heated bed power pins to control the Peltier power using the same G-codes
|
||||||
|
* as the heated bed (M140, M190, etc.).
|
||||||
|
*
|
||||||
|
* A second GPIO pin is required to control current direction.
|
||||||
|
* Two configurations are possible: Relay and H-Bridge
|
||||||
|
*
|
||||||
|
* (At this time only relay is supported. H-bridge requires 4 MOS switches configured in H-Bridge.)
|
||||||
|
*
|
||||||
|
* Power is handled by the bang-bang control loop: 0 or 255.
|
||||||
|
* Cooling applications are more common than heating, so the pin states are commonly:
|
||||||
|
* LOW = Heating = Relay Energized
|
||||||
|
* HIGH = Cooling = Relay in "Normal" state

|
||||||
|
*
|
||||||
|
* When "cooling" in addition to rejecting the heat transferred from the hot side to the cold
|

|
* fan that can be powered in sync with the Peltier unit.
|

|
*
|

|
* This feature is only set up to run in bang-bang mode because Peltiers don't handle PWM
|
||||||
|
* well without filter circuitry.
|
||||||
|
*
|
||||||
|
* Since existing 3D printers are made to handle relatively high current for the heated bed,
|
||||||
|
* we can use the heated bed power pins to control the Peltier power using the same G-codes

* as the heated bed (M140, M190, etc.).

|
*
|

* Peltier Bed - Heating and Cooling
|
||||||
|
*
|
||||||
|
* A Peltier device transfers heat from one side to the other in proportion to the amount of
|
||||||
|
* current flowing through the device and the direction of current flow. So the same device
|
||||||
|
* can both heat and cool.
|
||||||
|
*
|
||||||
|
* When "cooling" in addition to rejecting the heat transferred from the hot side to the cold
|
||||||
|
* side, the dissipated power (voltage * current) must also be rejected. Be sure to set up a
|
||||||
|
* fan that can be powered in sync with the Peltier unit.
|
||||||
|
*
|
||||||
|
* This feature is only set up to run in bang-bang mode because Peltiers don't handle PWM
|
||||||
|
* well without filter circuitry.
|
||||||
|
*
|
||||||
|
* Since existing 3D printers are made to handle relatively high current for the heated bed,
|
||||||
|
* we can use the heated bed power pins to control the Peltier power using the same G-codes
|
||||||
|
* as the heated bed (M140, M190, etc.).
|
||||||
|
*
|
||||||
|
* A second GPIO pin is required to control current direction.
|
||||||
|
* Two configurations are possible: Relay and H-Bridge
|
||||||
|
*
|
||||||
|
* (At this time only relay is supported. H-bridge requires 4 MOS switches configured in H-Bridge.)
|
||||||
|
*
|
||||||
|
* Power is handled by the bang-bang control loop: 0 or 255.
|
||||||
|
* Cooling applications are more common than heating, so the pin states are commonly:
|
||||||
|
* LOW = Heating = Relay Energized
|
||||||
|
* HIGH = Cooling = Relay in "Normal" state
