I have this printer for some time. Everything was working fine. Unfortunately, I wanted to upgrade the firmware. I flashed the official 1.0.6 firmware correctly. But after booting up it asked to do auto Z offset and bed levelling. It was going into loop for few minutes and gave QR code error message. This was happening for lot of time. Finally, it successfully finished the routine. But then I was that the z offset was set at 0.
I manually set the z-offset, but the auto bed levelling is now giving error.
The printer goes to center, tries to home, Drops CR Touch probe, lowers head till the light changes to blue. Rises, retracts the probe.
Then starts the bed levelling routine by going to bottom right. Drop the probe, tries to lower head, But stops before the probe touches the bed. Rises, and moves to bottom left and repeats.
When I try to do Auto Home, it goes to center, drops probe, lowers head till light turns blue and rises. When I go into Move menu and change Z to 0.0 (from 10.0) the nozzle does not touch the bed. If I try to go into setting z-offset, when the nizzle finally touches the plate, it reads close to -5. I know my original x- offset was -2.44
What can I do? It’s as if the printer is wrongly zeroing the Z axis. I.e. when the probe touches bed, it’s marking it as -2.44 instead of 0 (If that makes sense.) IF I try to manually do bed levelling, I get all points in -2.5 range.
