The machine calibrates in the vertical, but when automatic calibration is chosen the rods fall off as soon as it starts to move in x & y. Can anyone help.
All sorted, slider bearings were to tight towards bottom. Undid rod screws top and bottom slid the slider to top and nipped up screws, did the same at the bottom. Slid slider to top again and tightened then the same at bottom. Oil on rods and slip them up and down a few times. All started working.
