Sturdy and Fast all Steel CNC , my first build

[Boyan Silyavski]

Hello Sir! Amazing work!
How did you adjust Y axis bearing blocks against the Y rails? Did you weld the hole assembly of 10mm lasercut steel?

Thanks!
Yes, i welded the whole assembly, in fact all on the machine is fully welded except the Z assembly, which is spot welded almost fully-spot by spot each next to the other.


You mean how i squared the gantry? Y is my 2 long rails. After the epoxy they were on 1 plane. Then using straight edge and precision square i squared them. Then mounted the bearing blocks. Then mounted the gantry on top of the bearing blocks with bolts loose. Then using again straight edge touching the bearing blocks i squared the bearing blocks both sides. Then tightened the bolts that hold the gantry over the bearing blocks. So the gantry was now square.
Now have in mind all was was welded <1mm at least. Also the rails on the gantry were not drilled yet. Later i squared the rails on the gantry, fixed them with clamps and then drilled on place. Look at post #93
