I prefer an extra day to solve the perpendicularity of my machine, that to mess with the software. After all i spent 1 week mounting the 3m long square rails on my machine and had to dismount them a couple of times to correct parallelism. Not to speak of the 3 times pouring epoxy until i learned to control 100% the process . Each pour was around 150euros in epoxy.
That was solving the parallelism. But perpendicularity? i would say all i mount is less than 0.01mm in perpendicularity. Facts speak that i did not have to tram spindle at all when i finished my machine, no need for dial indicator after mounting all just using some thinking, straight edge and 2 precision squares.


I have to check the manuals of the expensive chinese controllers. But i doubt that, as any would expect from a milling machine to be build 0.000 not 0.00 straight
