PCB Heatbed-What You Should Know About


The PCB heatbed was developed by Josef Prusa. Thus any other new design will always be based on this model. The heated works based on the theory that when an electric current is passed through a conductor, it produces heat that is proportional to the number of amperes flowing through it. Such as, a heated can be set produce as low as 120W of power or 200W depending on the needs at either 12 or 24V. Notice that the resistance of the passionate determines the wattage that will be dissipated.


The higher the resistance, the less the current and the less the power. However, care should be taken to control the current because if it exceeds certain limits, it increases the chances of burning your track PCB.

1.How to Connect the Board

The PCB heated can be connected either way because it utilizes LED’s which does not depend on polarity as long as the right pads are used. Using a dual power option is recommended if you want to get the desired results. Also, it is essential to ensure that the wires you use can handle the resultant current.


2.Heating the Bed

If you will be using your PCB heatbed, choosing the right temperatures, which you will be comfortable with is recommended. You will have to experiment so that you find out what works for you with the filament transition temperature varying. Note that choosing the right temperature is also recommended.

Also, buying the right PCBs is critical because you will get plenty of cheaper PCBs out there, but most of them will be too thin or come with an irregular copper wire that makes it difficult to heat the board. PCB heatbed that are insulated and which can fit behind the water radiator may be a good option for you.


3.Mounting the PCB Heatbed

The PCB heatbed comes with two sides and two copper traces at the bottom and the top. Also, the modern PCB heatbeds has silk on either side. So using a piece of glass to print the surface is recommended since it protects your copper traces. However, it is essential to take some care so that the springs do not damage the glass when they collide. Also, it is important to note that collision of LED, wire connections and resistors can also lead to the crash. The current PCB heatbed comes with a glass that can be used to mount PCB heatbed. It helps improve the transfer of heat to the glass, and this enables the board to heat fast. Notice that using PCB with a lens helps to enhance the transfer of heat allowing the PCB to heat even faster.


To connect the PCB, you may choose to use LEDs only after installing the resistor. Typically, the LED is mounted in different directions to enable any of the LEDs to light up even when the polarity changes. Using heatsinks on the heated bed is recommended especially when it gets too hot.

4.Troubleshooting the Heatbed

Typically, the heatbed will at times become a source of problems and so it may be necessary that you troubleshoot it to diagnose the nature of the problem. If it does not turn on when powered, the power supply may be faulty. Similarly, if you realize that it does not attain the required temperature or if it is taking too long to accomplish the desired temperature you may need to call a technician to examine it.
