Unstable Z (@calibration)
Running My Z calibration seems to jump by at least 0.6mm after i changed BL touch Z offset.
e.g. i adjust the "z offset" by 0.05mm and the physical offset changes from the usual range of -0.1 to +0.1mm, to the something like -0.2mm to +0.8mm - with a large random element to it.
Config snip (including previous value):
BL Touch
[include config/z-probe/bltouch.cfg]
[bltouch]
#z_offset: 3.30 # HBS april 2023
z_offset: 3.35 # HBS april 2025
As you can see my offset is unchanged for two years, and I only did a very small adjustment but now it is all over the place after every calibration.
i have double checked for physical problems, and find nothing - everything seems as rigid as expected.
Info:
Vcore3 500, changed to V.3.1.
Klipper, RatOS 1.0
Prefered z-offset verification: heat bed to 60C, heat Nozzle to 200C, wait 5-10 min. auto calibrate x,y,z, z tilt, and z again. 0.15mm paper under nozzle, adjust z down til resistance i felt when moving paper.
The printer is usually very stable, and nothing was changed for a year or so....

Update RatOs from 1.0
Hi, is it possible to upgrade a RatOs 1.0.0 to a recent version?
Sorry for this stupid Q, but it seems un-seachable in the forum.
Main reason for updating is the KlipperScreen "Python too old"...
I think the the RatOs documentation expects a newer version - or at least i have troubles following the guide....
**So the Q is: is it possible (reasonable) to upgrade, or should i toast the hole thing and install from scratch?
(I have a lot of Linux experience)
HW: RPI3b
Host(armv7l, 32bit)
Version: v0.12.0-485-g46ee920b9-dirty
OS: Raspbian GNU/Linux 10 (buster)
Distro: 1. 0.0

XY Stepper error
On my RatRig Vcore3-500 I sometimes get:
TMC 'stepper_y' reports error: DRV_STATUS: c0130010 s2vsa=1(LowSideShort_A!) cs_actual=19 stealth=1 stst=1 Once the underlying issue is corrected, use the "FIRMWARE_RESTART" command to reset the firmware, reload the config, and restart the host software. Printer is shutdownSometimes it appears shortly after powering on the printer, sometimes after an hour of printing, sometimes not at all. (typ. print time 0.5-2h) Sometimes it reports the short on channel A, sometimes on channel B. But always 'stepper_y'. The cables are factory crimped and are looking perfectly fine. I tried to swap cables - no change. I tried to replace the TMC2209 driver with a brand new one - no change. The printer was purchased as a kit from RatRig, the control board is SKR PRO V1.2 with TMC2209 drivers. I guess it have been running 500-1000h in total, ...one puzzeling detail: the problem started immediately after upgrading to Ratos on the RPI (which also upgraded everything else) So I guess I have a stepper with a 'moving' short... that by random chance appeared after 'upgrading' software. Any suggestions to other problem sources are welcome (e.g.PSU?) If I replace the XY steppers, should I go for another make/model? Any comments are welcome 🙂
