Issues since CURA upgrade

Sovol SV03 BIG DD 3D printer

Hello, have had issues since upgrading to latest CURA. Printer begins correctly, X,Y,Z homes, autolevels, then homes again 2 or 3 times then locks up at X,Y origin. I have re-written the Start G-Code per both old and new instructions, still same issue. Have also un-installed latest CURA and re-installed 4.7 with both start G-Code settings. HELP!

Start G-Code:

M201 X500.00 Y500.00 Z100.00 E5000.00 ;Setup machine max acceleration

M203 X500.00 Y500.00 Z10.00 E50.00 ;Setup machine max feedrate

M204 P500.00 R1000.00 T500.00 ;Setup Print/Retract/Travel acceleration

M205 X8.00 Y8.00 Z0.40 E5.00 ;Setup Jerk

M220 S100 ;Reset Feedrate

I’m not 100% sure whether this is what you’re facing, but I’ve experienced similar sounding lock ups when I went to a different board, and compiled firmware for it.
It ended up being BLTouch related, and the stock firmware will retry levelling three times before it gives up, if I’m remembering correctly.
Can you double check that the BLtouch wiring is in correctly, and you don’t have a wildly unlevel bed from the beginning (as in, go do the corner levelling).

Good luck!

Edit: Oh man. I just realised how old this post is. Sorry!!! Decided deleting was not helpful, so keeping my shame up :slight_smile:

Hello reildeal
Are you using a touch screen? Solution two can verify
1, operation initialization, restore factory settings.
2, modify the start gcode.

Change to G28 ;Home

M420 S1 ;
Require automatic leveling before selecting a file to print, so that you do not need to execute G29 again for automatic leveling if you select a file to print

Thank you
Best regards
