The only issue is that the backwards movement takes the gantry a long
way from the papaer pick up point, so far that it thinks it has
failed. Will be interesting to see, I guess this means your machine
will be quite long?

Same as the HP, if you look at my last video at the top left of the
mdf bed you can see a piece of card sticking upwards, this is just
pinned to the side of the base. The opto is on the gantry and the
card slots into it. Its easy to adjust too.

That's pretty much what I am doing, the build and supply boxes are
less than half the size of a page although I think they could be a
little bigger as the printer can keep feeding for a while.

I'm going to have to hurry up Fogassa or you will overtake me :)

Good luck with it!
