I have not had any issues mounting the drives vertical for optimal cooling is important.
This is one I have started to work on with drives not mounted.
I am going to add a fan directly above the space for the drives at the top side of the box per the manual.

Do I understand right, that there isn't need for such shielding (haven't seen none of pictures where something like that are made as manual are succeeding) and when do do that there isn't good way to cool drives.

I've added a bit more to the enclosure now

I'm hoping adding metal walls for shielding is not required.
I have had cooling issue with Lams when not installed per the instructions so I have a fan per their specs.
Elsewhere the manual shows using a lot of fuses on high voltage power to the drives.

I made a similar enclosure with the same toroid previously driving ethercat drives and had no problems with noise. It was in a smaller case so it was more cramped!

I will use 5 pin connectors for motors and will bring the cable shield inside on one so it can be terminated on the driver. I have also given some thought to cable layout and will keep mains, stepper motor power and logic apart.
I also have a high quality mains filter on the IEC connector.

I might add that when talking to the Australian distributor he said that Lam always promoted absolute best practice so it is possible to take shortcuts at your own risk  :)

I made it like this, bigger box was to big so I have to mount everything here.
Most components have find her place and connection made inside the box.
 
I have to make good schematics, I already have no idea what I have done here.

LAM drives ... yummyyyyy :)
While on the subject, do you have the programming dongle for them?
Supose you do, so have a look at RodW setup where he uses the boost feature to push more current to the motors while accelerating and lowering it when at speed. Might make it possible to push the machine faster while still keeping the motors cool.

Yes I have.
With most mechanical side I think I can handle but all the programing part it gonna be hard, I have no idea what to do.
To be honest there are so many questions I even don't know where to start with them.
I even don't know how to connect drives to the board...

I have not quite finished the programming yet but all the wiring is done.

And yes I will be using the lam boost feature with a custom component.

My reccommendation is to start writing a document that has a series of tables as per the attachment.
Make sure you update the table before adding any wires. I found it was realy simple to build the config once that was done.

I was working on it today and was fighting with QTplasmac because it uses so many halui pins that adding external buttons and MPG's can be quite a chore! Lots of or2 statements.

What halui pins require an or to be able to make use of?
