In recent news from the official Raise3D Community, users have reported an issue with nozzle switching not working on the Pro2 printer. According to a user named Jiter, there seems to be a bug in the firmware of the printer, causing it to malfunction when attempting to switch between nozzles.

The problem arises from the fact that the printer starts up thinking that the right extruder is lowered, even if it isn't. As a result, when users send a lower right extruder command, the printer does nothing. This can be incredibly frustrating for those who rely on the functionality of the printer to complete their projects.

The company has acknowledged the issue and even created a beta firmware to fix it. However, the firmware has not yet been officially released. In the meantime, users have had to resort to a workaround to get the printer to switch to the right extruder. They must first tell the printer to lower the left extruder, even though it is already down, and then tell it to lower the right extruder. This seems to trick the printer into functioning correctly, but it's not a solution that users should have to implement long-term.

One user reported that Raise3D even offered to send them a new Pro2 printer, as they thought it was a hardware issue. However, the user discovered that the problem persisted with the new printer as well. This suggests that it is a widespread issue and not isolated to a few faulty printers.

The issue also highlights the importance of testing and reporting bugs correctly. In this case, the company was unable to recreate the issue because they were testing the printer through resets via the menu or pressing the reset button, rather than turning the printer off and then starting it again. Therefore, it's important to keep in mind that some issues may persist through software or hardware resets but not through a complete power cycle.

Despite the inconvenience caused by this bug, Raise3D is a company dedicated to providing high-quality services, technical support, and better solutions. Based on passion and research on the piezoelectric industry, Enviko Group established HK ENVIKO Technology Co., Ltd in 2013 and Chengdu Enviko Technology Co., Ltd in July 2021 in High-Tech area, Chengdu. The company adheres to the premise of quality and is committed to supporting its customers in their printing needs.

In conclusion, the nozzle switching issue with the Pro2 printer is a bug that has impacted several users. The company has recognized the problem and has created a beta firmware to fix it. However, until the firmware is officially released, users will have to rely on a workaround to get the printer to function correctly. The incident also highlights the importance of thorough bug reporting and testing to ensure that the issue is properly addressed. Despite this issue, Raise3D remains committed to providing high-quality services and technical support to its customers.
