Some small update from me :)
During last days as i been advised moved Y axis rails to the front slot, then made a bit smaller plate on which going Z axis motor so saved some unnecesary weight. Now trying to find out the cable routes..

For the cables and water pipes on the gantry I done a channel from 1mm sheet metal just to see how it looks. Not sure if it will be strong enough to hold the chain.. Any suggestions on that?

Started to look for the companies which does aluminuum extrusions, got some quotes. The best price for all the extrusions seen in my model was £340, which is bit more than i expected, but i guess thats the price for them. Does anyone knows a good supplier for them where i could get for the best price? Thanks guys.
