Plasma table build, first question....

[Boyan Silyavski]

As it would be only plasma machine, you could go light and simple on everything. Take a look at the ebay kits they sell and improvise. The Proma kit they sell at they web also. I pointed it to you as the second piece is the Z driver and will simplify things even further if you have not bought the drivers for the motors. Look at his simple Z axis.

it not my machine, cause the part i want to show you is hidden inside, so i can not make photo of it but that's what i meant for clocking the gantry belts:





that is good idea for simple Z DIY CNC Plasma cutter axis rail car for nema 23 stepper motors | eBay



If i were at this point where you are, i would buy a 1 second hand wide type square rail with bearing block or two for around 100-200eur shipped to you from ebay for the gantry, as it will be far better than the other solutions. This wider type of rail will hold a very light z perfectly, move it fast and precisely and simplify a lot the build.
