Firmware 2.03beta2 available

Hi. So far, I've been with firmware 2.02 RC3 in my Kossel.

When I calibrated the bed with G32 with calibration factor 8, after two passes, I had some 0.05mm measurements, the difference between each measured point, and the first layer was very good

I have updated to the latest version, 2.03 beta 2, and when doing the G32 calibration several times, I get disparate measurements between the measured points of up to 0.2mm. Now the first layers are uneven in different parts of the bed.

Have I missed something? Has anything changed in this latest firmware?

Thanks and best regards

There has been no intentional change in this area. There might have been an unintentional change because the code that handles endstop corrections has changed. Can you revert to 2.02 and check whether the new firmware really is to blame?

@dc42

Okay. I go back to 2.02 and try it later.

Thank you

Hello,

With the 2.02 final it works correctly again, as in 2.02 RC3.

At least in my case there is something weird about 2.03 Beta 2.

I've found a bug which might explain the problem, if you don't home the printer between auto calibration and printing. So please try 2.03beta3 when i release it. Meanwhile, homing between auto calibration and printing should work around the bug, assuming that your homing switches have reproducible trigger heights.

@dc42 does only apply to G32 or also to G29 mesh calibration?

Only to delta auto calibration.

In agreement. When beta 3 is available, I try it. Thank you.

Beta 3 is available now.

In agreement. I'll try it this weekend.

Hello,

It is already tested and in beta 3 it works correctly again.

Thanks and best regards

When running G29 now the printer is using the nozzle reference and my z probe is out of the bed area. But when showing the map it thinks it was the probe at the nozzle position.

The only change should be that if you run G29 within a system macro file (for example, bed.g) then tool offsets will be applied., whereas in firmware 2.02 they are not. But Z probe offsets are always applied by G29. Are you using tool offsets?

brunofporto

@dc42 Not using any tool offsets. The only offset is the z-probe defined at the z-probe configuration line.

Pretty sure it is putting the nozzle exactly where it should be the probe when I send a G29 - needed to change some parameters to make sure the probe is over the bed but the height map shows as the nozzle position is where the probe took the measurement.

@dc42 ps.: just realized that I post at the wrong thread! I am using the beta3!
