+==== A3S or A3S MkII? ====
+<alert warning>
+Please note, JGAurora has released a **second-generation A3S MkII** for 2019, which is based on the [[/a5s|A5S]] printer. If your A3S has an SD card slot at the front, then you have the new version, and should refer to the [[/a5s|A5S]] page for more relevant information. If your A3S has a USB stick port on the side, then you have the first-generation A3S, and should read on! :-)

 ==== General Infomation ====
 These printers have TWO motherboards - there is a main motherboard (it is an {{:a5:mks-gen-l.jpg?linkonly|MKS Gen L}}) which runs the printer, and a second motherboard attached to the LCD (an {{:a5:mks-tft28.jpg?linkonly|MKS 2.8" LCD module}}) which handles the LCD touch screen interface. They are completely separate devices, and the only communication between the two occurs by an internal serial port. The LCD motherboard sends basic gcode commands to the main motherboard, and then listens for the replies.

   - V9 with bed clips (no longer stuck down with adhesive), no more cut off corners, power supply replaced with generic brand, Z-smooth-rod holders are now injection moulded, not machined metal.
   - V10 with A4988 stepper drivers that are fixed-vref, and cannot be tuned. For better or worse!
+  - V11 with 6-pin bed cable (__big safety improvement__)
 If you ask nicely, in some cases JGAurora has been known to provide replacement upgrade parts, either for free, or for a discounted price. They do not have a clear policy on this however, which can be disappointing for those early customers. :-(
