| # 3.3.0 | ||
|
|
||
| ## Summary | ||
| * Max. 255 minutes runtime | ||
| * Fix: wash cycles | ||
| * New filter cleaning mode | ||
| * Travis build was removed | ||
|
|
||
| ## Detailed description | ||
| ### Max. 255 minutes runtime | ||
| The maximum run time was set to 255 minutes for all operations. | ||
|
|
||
| ### fix: wash cycles | ||
| Wash cycles were not performed correctly after rotator run time changes. | ||
|
|
||
| ### New filter cleaning mode | ||
| Added a new “filtering” mode for cleaning IPA with a filter. This is another | ||
| washing mode without changing the direction of rotation with its own speed and | ||
| running time. Value settings are in the usual places. There is a new item “IPA | ||
| Filtering” in the main menu. Please refer to the updated user manual for | ||
| further use of the filter. | ||
|
|
||
| ### Travis build was removed | ||
| Building with Travis is no longer supported and future releases will not be | ||
| released using this system due to the limiting of terms of use on the Travis | ||
| side. | ||
|

| # 3.2.0 | ||
|
|
||
| ## Summary | ||
| * Code refactoring and optimizations | ||
| * Automatic fans control | ||
| * New heating algorithm for CW1 device | ||
| * Set all timers to max. 60 minutes | ||
| * Do not handle info pages as menus | ||
| * Change motor direction while washing | ||
| * Factory reset | ||
| * Improved self-test | ||
| * Allow to extend the run time to a defined maximum | ||
| * Updated documentation | ||
|
|
||
| ## Detailed description | ||
| ### Code refactoring and optimizations | ||
| * The code for CW1 and CW1S was splitted into separate files for easier modifications. | ||
| * The Makefile was improved to support the build of different devices via command line option. | ||
| * Pluggable USB in USBCore library was dissabled to save space. It was not used. | ||
| * Menu with live values of fans RPM and temperatures was removed to save space. | ||
| It was used only for debugging purposes and had no importance for the user. | ||
|
|
||
| ### Automatic fans control | ||
| Prior to this version, the fans were set to a fixed speed. The fans are now | ||
| controlled according to the cooling demand. In most cases, they can remain at | ||
| the lowest possible speed and increase to the maximum only when the temperature | ||
| rises. This may affect device noise during certain operations. | ||
|
|
||
| ### New heating algorithm for CW1 device | ||
| The heating method was changed for original CW1. Newly, it tries to maintain | ||
| the set temperature in the chamber. CW1 can only switch the heating on and off | ||
| and, as a result, the temperature in the chamber fluctuates. These adjustments | ||
| were necessary for longer heating times, when CW1 significantly overheated the | ||
| chamber. If you have had your favorite heating temperatures, you need to revise | ||
| these settings. Please note that the maximum allowed temperature of 60 ˚C | ||
| (140 ˚F) is the limit and may affect the life of the device. | ||
|
|
||
| ### Set all timers to max. 60 minutes | ||
| All operations (curing, drying, washing, resin preheating) can now take up to | ||
| 60 minutes. | ||
|
|
||
| ### Do not handle info pages as menus | ||
| The information page is displayed as scrolling text only and allows you to view | ||
| the entire serial number. | ||
|
|
||
| ### Change motor direction while washing | ||
| For washing, it is now possible to set the number of washing cycles. One cycle | ||
| is the rotation of the impeller in one direction. The length of one cycle is | ||
| calculated from the total washing time so that all cycles last the same time. | ||
| This could improve the efficiency of washing prints. The default value is one | ||
| cycle, i.e. washing without changing direction as before. | ||
|
|
||
| ### Factory reset | ||
| In the advanced settings (long press in the settings), a factory reset is now | ||
| available, which applies the default settings of all configurable values. | ||
|
|
||
| ### Improved self-test | ||
| The UV LED and heater test run only for the necessary time instead of a fixed | ||
| time. | ||
|
|
||
| ### Allow to extend the run time to a defined maximum. | ||
| The increase of run time during the ongoing operation was limited to 10 | ||
| minutes. Newly, this value is the maximum for each operation (60 minutes). | ||
|
|
||
| ### Updated documentation | ||
| The README has been updated and a CHANGELOG has been created. | ||
|

| # 3.1.0 | ||
|
|
||
| ## Summary | ||
| * Support for CW1S | ||
| * Drying temperature increased (CW1S) | ||
| * Drying session extended | ||
| * Hold the platform (new feature) | ||
| * Improved translations | ||
|
|
||
| ## Detailed description | ||
| This is the final release of firmware 3.1.0, the first firmware release with | ||
| support for both the CW1 and the new CW1S. `Attention, the firmware is not | ||
| universal, each device requires its own firmware file!` | ||
|
|
||
| ### Support for CW1S | ||
| This release of the firmware brings support for the recently announced Original | ||
| Prusa Curing and Washing Machine CW1S. The CW1S features a reworked heating | ||
| system, which required a completely redesigned heating algorithm. | ||
|
|
||
| ### Drying temperature increased (CW1S) | ||
| As mentioned above, the CW1S brings reworked internals with the aim to improve | ||
| its drying capabilities. This firmware release enables CW1S owners to increase | ||
| the target temperature up to 60 °C. Note that the limit for CW1 is 40 °C. | ||
|
|
||
| ### Drying session extended | ||
| Previously, the system allowed for a 10 minutes drying session. This is now | ||
| extended to 60 minutes for both CW1 and CW1S. | ||
|
|
||
| ### Hold the platform (new feature) | ||
| Original Prusa CW1S brings a removable platform protected with an FEP film. | ||
| Once there is a bigger amount of residue on the film, it might be necessary to | ||
| replace it with a new one. To help align the platform back to its original | ||
| position, the user can activate “Hold the platform” from the menu. | ||
|
|
||
| The motor gets “locked” (rotation is disabled) by the system, temporarily | ||
| allowing the user to align the platform properly. Once the platform is properly | ||
| seated, exit the menu to “unlock” the motor. | ||
|
|
||
| ### Improved translations | ||
| Since there are some changes to firmware 3.1.0, the translators have rechecked | ||
| all the language strings. Should you find any incorrect translations, please | ||
| let us know. | ||

| # 3.0.0 | ||
|
|
||
| ## Summary | ||
| * Code refactoring and optimizations | ||
| * Firmware localized into 7 languages | ||
| * Resin preheat | ||
| * Extended curing time | ||
| * Factory self-test | ||
| * Updated user manual | ||
|
|
||
| ## 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) | ||
|
|
||
| ### Updated user manual | ||
| The technical documentation was updated and is covering all the changes and new | ||
| features introduced in this firmware. You can download an online copy of the | ||
| CW1 user manual from here https://prusa3d.com/drivers | ||
