Thank you, but I already have my build platform attached. I'm referring to the other thick sheets - for mounting the electronics to and such... I have several pieces of laser cut MDF and I can't find anywhere where it shows how/where to attach these..
What electronics do you have? There are many ways to attach the different type of electronics and thick sheet. You might want to draw inspiration from the way sells mendel attach the electronics, but you are free to improvise and attach them where you'd like.
I for one, use this: [www.thingiverse.com] for one gen3 set, and have made my own mounting plate for another set.
