Print cancels with Ender 3 at beginning

[Minibohne]

What is the problem?

Octopie is connectected via cable and USB to my Ender3v2. I am new to all this and made a fresh setup today on a Raspberry Pi4. At first Octopi told me that the firmware of the Ender was outdated, so I also updated that. I set all the parameters in Octopi. Bed size, nozzle heat and so on. I can connect via Webinterface to the Pi and I can move axis and see all through camera. I load a file and press print. The printer heats up, first bed then nozzle. As soon as parameters reached the nozzle moves to left side and hits the stopper but the stepper engine does not stop and tries more often to move to left and then the printer kills connection.
Without octoprint the printer prints everything as the last 2 weeks as normal - no problems at all.

What did you already try to solve it?

Have you tried running in safe mode?

Hello @Minibohne !

The printer itself is cancelling the print during homing:

For this is a Creality printer, you may

• check if the endstops are activated during homing
• try with/without SD card in the printer's SD card slot
• and or this: Put tape on the 5V pin - Why and how

@Ewald_Ikemann

check if the endstops are activated during homing

Where do I do this, sorry as I said I am very new to 3d printing. Thank you.

@Ewald_Ikemann

try with/without SD card in the printer's SD card slot

First, I would try this one - it is a known issue with Creality's firmware when the printer is connected via USB

My Creality printer ignores its endstops when homing from OctoPrint

There have been some cases where Creality printers ignore their endstops if connected to OctoPrint and no working SD card is present in the printer (sd init fail). If you encounter such an issue please see if putting a (FAT formatted) SD card into your printer's SD slot solves the issue. If there already is a card in there, test if removing it or swapping it with a known-to-be-good one helps.

try with/without SD card in the printer's SD card slot

Can´t beleave it- yep works now, just left SD card insertet. But also running secure mode now. Will check in an hour after print if normal also works. Thanks so far!
