Black Cat 3020 CNC not cutting square problem

[Fivetide]

Oh dear...

firstly, you will need to get yourself an engineers square. These are cheap at machine mart, get one that will fit to the table of your machine.

You will need a dial test indicator too #(DTI).

Basically you will need to measure how out of square your machine really is.

So, watch this vid to see how to square your engineers square along the X axis. It is for a vise but it illustrates the point I am trying to make: https://www.youtube.com/watch?v=WR9tLu_nGxg

With that sorted, and you square trammed in, you should see how the DTI trams along the y axis. I would suggest all the movements of the axis be done by hand.

See this one too: https://www.youtube.com/watch?v=AzhmMp2fLSw

Do the measurements to see how far out you really are before you even think of bashing anything.

If you see that the machine is within 0.02-0.03mm square, then you are facing an electronics problem where you are losing steps, the steppers are stalling or your motion control hardware is on the blink.


If you need any help give me a shout.

If was only that I could live with it :) Thanks for the replies everyone.. let you know how I go on.
