can deviation value change by itself?

[reahax]

Hello,

When i calibrate my delta printer, the deviate value about 0.060 mostly.
But after i while the deviate value changing by itself, is it normal ?

The deviation value was around 0.055 before this calibration. After calibration its says "deviation before 0.435" but it wasn't.

It all depends on how stable the frame of yor delta printer is, whether there is any play or backlash in the joints, and similar things.

Also, calibration parameters are forgotten when you power cycle the printer, unless you saved them.

Thanks, then i should make aluminum brackets for my delta for more stiffness.
