I made SL1S calibration using the printer wizard.
I printed a test model and the result was great.
I took out USB drive to my pc and copy another model.
When i come back to the printer the power was off (maybe asome Time Out) so i press the front button and the printer went ON.
I put the USB drive it the printer and stated to print the new model.
The printer start hitting the platform against the bottom of the tank and made a lot of knocking noise. It seems that it is not calibrated at all.
I stop the print and use calibrate wizard again. I noticed that the Tilt start value wasnt as i set it up in the last calibration procedure. So i calibrate again and print with no problem/
It happened to me after every print, after power shut down.
Why the calibration data lost?
Any knowladge or solution for that?
Thanks
