Hello Clive

Yes i need a reinforced base but i only had 40X40 bars( recycled from other machinery). For this reason i use "6 legs" to support the weight of machine. But it is possible that i will place some triangles to reinforce all structure.
Z also have linear rails from THK and ballscrew from NSK, it is a complete "head" dismantled from another machine.
Sure most of the parts are 20mm but there are a few like motor supports and spacers that was not necessary.
What is the difference of non linear power supply and others?

Thanks
