VM8201 setup

Hi guys,

I’ve just received my vm8201, plugged it in, the backlight comes on but nothing else.

I’m currently using the following firmware, is it the latest marling firmware,

github.com/CONSULitAS/Marlin-K8 … -11-18.zip

If not could you point me to the latest, if it is the latest what changes so I need to make to allow the LCD to work.

Cheers.

If you are using the stock K8200 and only adding the VM8201 try this one
http://www.k8200.eu/downloads/files/downloads/firmware_k8200_marlinv2.zip
There is also a contrast adjustment on the bottom of the unit you could try adjusting that.
Check the solder joints on the pins you soldered on the board.

When I bought the printer it had these mods,

Acme Lead Screw, 1.75mm J-head extruder, Reinforced z axis holder.

Is it possible to just use the latest marlin firmware, I can see that the k8200 has a configuration file already in the source code.
