G29 command not working from Tronxy X5SA 400

[BahamutWolf]

Hi,

I renamed the Tronxy X5SA 400 printer profile to D01 PLUS and saved it. Nothing was changed except the print area from
400x400mm to 330x330mm. When printing, it moves to the middle of the print bed at G29 and only moves up and down the Z axis several times instead of traveling and measuring the print bed. I use Tronxy's black sensor and don't own a BL or CRTouch.

Thx.
