How good is a sub ?100 3d printer ?

[hutchouk]

I was assuming that by having a separate arduino board I'd be able to access the unused GPIO pins. Does the MKS Gen L board still give easy access to these pins then?

I'm actually struggling to find detailed information on any of these boards.

All boards have these pins. you just have to find them. MakerBase is a big name in 3d printers and finding a data sheet for these controllers is actually pretty easy. either from google or bing or the search engine of your choice. But since you said you are struggling to find info, I did this google search for you. Here is the first thing that came up in my search: http://www.robotrebels.org/index.php?topic=769.0
