Hi Silyavski,

I have to dig this old thread up as I have a tricky question (for me) regarding your frame.

I see that you welded your frame and everything including parts of the Z assembly. Did you do some stress relieve? If not, how the residual stress affect the accuracy, given that you have been using it for some years?

Thank you for sharing! Not only on this thread but others, I learnt a lot from you (particularly about belt and pulley) from another thread.
