I tested but cannot reproduce the issue you have. Please make sure you have the Marlin dependencies set as instructed here: /~https://github.com/bigtreetech/BIGTREETECH-TouchScreenFirmware#marlin-dependencies

Note: the "SERIAL_FLOAT_PRECISION 4 (in Configuration_adv.h)" is not needed, it's obsolete.

TFT70 here.

This is a "regression" in marlin code.
They killed the SERIAL_FLOAT_PRECISION, and fixed it to 2 digits.
This break the functionality.

Marlin nightly of 2023-05-14 is working fine. Not sure when they actually broke the code, but possibly commit ed4e22b of 2023-06-04.

They just reverted that change, SERIAL_FLOAT_PRECISION is back.

I do not see any sign of reversal. The last commit is 5 days ago. All I see is a bug report.

[kisslorand]

Yes, you're right, I remembered wrong.

I made a fix for it but for 2 weeks I am unable to make any more PR.
