 ??? info "GC6609 stepper drivers being used as well!"  
 
     It seems that Anycubic changed the stepper drivers from original TMC2208 to cheap 2208/2209 clones, called "GC6609".  
-    This is how they look (you'd need to take off the heatsink to identify which specific type was being used at your mainboard):  
+    When exactly this change took place and whether it's a permanent solution or if only a certain batch of these mainboards have been populated with these kind of stepper drivers is unknown.  
+    However, the following picture shows this stepper driver (you'd have to take off the heatsink to identify which specific type was being used at your mainboard - which I wouldn't recommend to do if you're just curious to know which one you have..).
