I finished building my mpcnc and I’m very excited about the result. It’s a great project!
But tonight I gave my mpcnc the very first try, a simple circle on a piece of wood:
The result is an ellipsis instead of a perfect circle.
I checked my frame and I found a perfect square.
I checked my rollers and I found some play on the two axis. My ellipsis is due to a non perfect square on x and y directions, or so it seems to me.
Is it normal to have some play on the axis? I hope so… To be honest I had to reprint the rollers scaling from the original model to 98% of the size. With the original size I had the bearing not touching the conduit tube.
With my scaled prints all the bearing adhere to the tube and I thought everything was right.
So my question is: is it normal to have some play on the rollers? I think I could start my mpcnc keeping the axis attached at the frame and send a M84 S0 to keep the rollers in place whit the steppers and then start my cut. Is it a solution?
Anyway tomorrow I’ll try this method to see if it works for me…
Anyone had issues like the this?
Thank you in advance…
