-====== Howto: Replace the Connectors on the Mainboard ====== 
-  
-===== Why? =====  
-{{:​reprap:​anet:​a8:​photo_2016-10-19_20-58-49.jpg?​600|board with burned pins}} 
  
-The green connectors on the board are not rated for the heatbed currency. Multiple users on the Facebook-Groups showed their burned pins, connectors or mainboards. To prevent this you should switch the connectors. 
- 
-===== Preparation ===== 
- 
-==== Parts ==== 
- 
- 
-You need: 
-  * new connectors with a pin distance of 5,08mm and a currency rating of at least 20A (ebay: AKZ120 or 5mm PCB) 
-  * soldering and desldering equipment 
- 
-===== Processing ===== 
-==== Warning! ==== 
-  
-If you have no experience in soldering you should give it to someone who knows how to do this. Messing up the connectors could lead to a fire, so give it to some electronics-guy. 
- 
-==== Desoldering ==== 
- 
-{{:​reprap:​anet:​a8:​photo_2016-11-05_01-19-02.jpg?​600|Board with stock connectors}} 
- 
-Desolder all three connectors. Heat the two pins alternating and pull them out or use desoldering tools like desoldering wick and a desoldering pump. 
- 
-{{:​reprap:​anet:​a8:​photo_2016-11-05_01-18-50.jpg?​600|Board without connectors}}
