Hard machine limits ignored by gcode
Maybe I need an explanation. I considered the machine limits set in the printer.cfg as hard and absolute limits. Usually these limits are set higher than the sliced gcode, so no probbs. No I wanted to testrun a gcode slower, set the machine limits to half the former speed and started the gcode.
Well, apparently, the accs of the gcode counted and overwrote the machine limits.
Is that actually correct?

Beacon und z-offset in printer.cfg
Irgendwie komisch. Beacon alte Revision gegen neue getauscht, mit BEACON_CALIBRATE das z-offset eingestellt, SAVE_CONFIG und voila... nada im unteren Teil der printer.cfg.
Vorab: In der printer.cfg stand ein z-offset drin, welches sich anscheinend nicht verändert hat, egal, wie oft ich BEACON_Calibrate ausgeführt habe. Ich habe den Eintrag gelöscht, um zu sehen, ob dieser neu generiert wird, dann obiges Problem.
Hat jemand einen Beacon am laufen und kann das nachvollziehen? Einfach mal neues z-offset machen und schauen, welcher Eintrag sich verändert?

TMC5160 PRO + Octopus 1.1 @ 48V Sensorless homing not working (new macine)
I just build a 200 mm RatRig with Octopus Pro V1.1 with Chip H723 at 48 V. I skipped on ordering the mechanical endstops as I was going for sensorless homing. The printer is working rudimentarily, but only as far as I tested it.
Activating the sensorless homing was done the following: Uncommenting the lines in printer.cfg and copying the one file over to the root of RatOs (two jumpers were also set on the Octupus, SPI Mode is configured for the drivers). Klipper just stalls with an error of specifying the UART port for both steppers, then, if done so, run_current. Final result is that it stalls with double entry for those pins. I was laughing at the comment in the printer.cfg where a simple instruction is given (not so simple as it seems).
I will paste all the logs, but the clue is given in in the thread TMC5160 PRO + Octopus 1.1 @24V Sensorless homing not working. It seems to be about the TMC5160, but I cannot solve it with my current knowledge.
