Firmware 1.5.0 - Print Quality Degraded After Update (Improved After Downgrade + Full Recalibration)

Hi Everyone,
We know V1.5.0 and V1.5.1 caused more headaches than they should have, and we sincerely apologize for that. To make sure we get things right this time, we’re taking a more cautious approach with the next firmware update. So now we’re opening up V1.5.2 Beta Test before an oficial release.

This version has actually been shared with a small group of users through technical support channels over the past few weeks, as a workaround for the print quality issues in V1.5.0/V1.5.1. The feedback so far has been quite encouraging. Now we’d like to invite more of you to put it to the test.

V1.5.2 focuses on Bug Fixes:

• Fixed an issue introduced in V1.5.0 where, in some cases, the first layer was overly squished when Heated Bed Leveling was not enabled before printing.
• Fixed an issue where the nozzle diameter could be incorrect in some cases.

After installing this firmware version, please complete the following steps:

• Run Multi-Toolhead Offset Calibration again with no filament loaded in any toolhead.
• Before starting a print, make sure Heated Bed Leveling is enabled so the printer performs bed leveling automatically before printing.
