Like Clive, my machine sits on wooden pads under each of the adjustable feet, which can be lifted to make use of the castors. The plan was to make the machine mobile so I can pull it away from the wall if I needed to work on long lengths of material. Wood or hard rubber (like the commercial adjustable feet) are fine.

those carts how many kg can they carry , because my gantry is becoming very heavy.

My rails are the SBR 20

is this the best set for the machine?

there will be a lot of replies that say "68V PSU and AM882 drivers." I agree - you are building a good machine so don't spoil it by using under-powered motors. Those motors themselves would be fine but they will really deliver better performance at a higher voltage and drivers to match.

SO 68V PSU and AM882 drivers is the better opion then?

the steppermotor's are they ok and i can mount them directly to the rack&pinion ?

or do i need to use a gearbox of some sort?
