Detailed description

Code refactoring and optimizations

The firmware for the CW1 was refactored in order to provide more space in the memory for new features and also to lower the CPU load. Most of the work on the code is not visible to the user, however, it was needed for the new functions introduced in this release.

Firmware localized into 7 languages

Until now, the firmware for the Original Prusa CW1 was available only in the English language. With this release, we are adding support for more languages. Apart from English, users can now also select:

• Czech
• German
• Spanish
• French
• Italian
• Polish

Each language is distributed as a separate firmware file. For example to install the German language select the file Prusa-CW1-Firmware-de-v3.0.0-rc.1.hex, connect the CW1 to your computer and flash the file over PrusaSlicer.

Resin preheat

Some advanced resins, for example, those used in the dental laboratories, require elevated temperatures in order to improve the viscosity. Without raising the temperature of the resin, the print will in many cases fail or the model won't be exposed to the UV light properly.
Based on the feedback from our customers, we have added this preheat feature to the CW1. Insert the resin in a bottle in the CW1, close the cover and from the menu select "Resin preheat". Based on the requirements of your resin, you can adjust the time in the range of 1 - 30 minutes and the temperature 20 - 40 °C.

Extended curing time

Advanced resins sometimes require longer curing periods and for this reason, the time was extended to 1 hour (60 minutes). Several resins were tested in our laboratory and the recommended curing times with CW1 will be included in the resin datasheet (RDS) on our eshop.

Factory self-test

Before every unit of CW1 is sent to the customer, a series of tests is performed to ensure the machine works as expected. The testing procedure is now part of a semi-automated test routine, with the following parts:

• Cover switch (semi-automatic)
• IPA tank detection (semi-automatic)
• Motor test - platform rotation (semi-automatic)
• Cooling fans (automatic)
• UV LED (automatic)
• Heater (automatic)
