Community Firmware v6 provisional release notes #159

Closed Sebazzz closed 3 years ago

Sebazzz commented 3 years ago

First of all I want to thank everyone for the support and positive reactions we got on the 5 beta release of the community firmware. All the testing and feedback has made this firmware better and better. Thank you for testing and sending your feedback. Months of work have come to an end with release 6 of the community firmware.

TLDR: Added PID tuning, interactive e-steps calibration, overriding slicer retractions, custom ABL probing settings, many more configuration knobs and stability improvements.

Hardware support

The CR-6 Community Firmware supports the following hardware configurations:

Add built-in experimental mesh validation pattern print (issue #196)

image Circles on every probe point

image Screen to run the calibration pattern

Add inputs to completely control the motion parameters of the printer (issue #189)

image Movement settings can be changed per axis

image There are also advanced settings available, you can tweak them if you like

Add some additional misc settings for the filament sensor or controlling PLR (issue #193)

image Some of you don't have a working filament sensor, so... disable it here (thanks to @ztakis for doing the graphics)

Add M73 R support which supporting Octoprint plugins or slicers like PrusaSlicer can use to emit a time estimate (issue #208) - check here for a full guide on how to activate this feature

image Time remaining shown - you now have your M117 status line available for other information, like layer height

image Corresponding setting in PrusaSlicer - it will also be possible in Cura 4.9 when it releases

@ztakis gave the printing screen a refresh, by reorganizing the status variables and adding the Z-offset back (issue #115)

PrintFromSD_CF6Pre5

New features added in previous releases

Safety

Important safety feature: We now enabled the watchdog for STM32F1 processors - if Marlin would freeze from some reason (like due to SD card issues) the printer is automatically reset and the heaters are disabled - this feature is not enabled on the stock Creality or BTT firmware

User interface

This release features an entirely refreshed user interface by @grobux! Improved font spacing, improved graphics. JPEG artifacts be gone!

image

In addition we implemented toggles allowing you to decide if you want to hear sounds from the touch screen (or not), and if you like the touch screen display to dim to 10% on idle (30 seconds currently).

Control_CF6Pre5

We've also implemented that you can tune the flow rate (the amount of filament extruded) during the print from the "tuning" screen. Very useful when tuning in new filaments. You can also control and review the fan speed percentage from the tuning screen.

flow-rate-tuning

You can also now quickly set the bed and hot-end temperature by tapping the temperature in the footer.

On the print screen we've added displays for the fan speed, flow rate, and X/Y/Z axis positions:

image

On this screen you can also set the hotend and bed temperature by directly tapping the numbers.

SD card folder support

We support navigation through folders on your SD card. No longer are you limited to 5 pages of gcode files. You can organise your SD card in folders.

folder-support

Hardware support

Octoprint

We have improved Octoprint support. We show the printer status messages also on the home screen.

image

The filament sensor is working and Octoprint acts on it - it pauses the print. Make sure you have the correct gcode in Octoprint so it parks the nozzle.

image

In addition when an Octoprint print starts we automatically show the "printing" screen with full access to all details and tuning options. You can also set the print progress using the the detailed progress plugin.

Features not available in this firmware

Flashing instructions

Note: This release is accompanied by a new firmware for the touch screen. This release and the new touch screen firmware goes hand-in-hand - one cannot be used without the other.

Touch screen flashing instructions

This release of the touch screen firmware comes with a new version of DGUS OS (the underlying operating system of the touch screen) to fix text rendering issues.

Flashing instructions are also available as a video - this video is for the Ender 3 V2 but the same procedure applies to the CR-6. For instructions, check the README.txt in the touch screen firmware download.

For this release the touch screen firmware and flashing instructions is included in the firmware release package. Be sure to follow the instructions carefully. If you experience issues, try flashing the touch screen a second or even a third time. It doesn't always "take" all the files. Sorry - hardware limitation!

Mainboard / Marlin flashing instructions

  1. If you like to remember what settings you had, run M503 in a serial monitor.
  2. Use an empty SD card formatted FAT32 4096KB sector size.
  3. Put the firmware ".bin" file from the zip file in the root folder of your SD card
  4. When using Windows - do a "safe removal" to remove your SD card.
  5. Put the SD card in the printer.
  6. Either turn the printer off, then on again or issue command M997 from Octoprint/Pronterface.
    • BTT SKR boards will flash the hot-end led while the firmware is flashed and rename the firmware.bin file to firmware.cur.
    • Creality boards will give no indication of correct flashing - except for the fact that it took a few seconds for the flashing to complete
  7. Verify the firmware is flashed by issuing M115 or going to "Control -> Info" on the touch screen.
  8. You can now remove the file from the SD card.
  9. After flashing go to the menu and reset to factory settings or issue M502 followed by M500 in Octoprint - do this also if you have been running an earlier release. You need to relevel the bed, recalibrate the z-offset, reprogram esteps (if you've changed them from defaults), and do a PID tune (if you find that the heating is not reliable for you or if you use high temperature plastics like ABS and nylon).

image The version should be shown when flashed successfully. If it is not shown, try rebooting your printer, reflashing it by renaming the .bin file, reformatting the SD card, or trying a different SD card

FAQ

Some frequently asked questions. Your question will most likely be answered here!

I have a CR-6 MAX with a BTT SKR CR-6 board

You need to compile the firmware yourself, we currently don't have an example configuration. If you have an example configuration, let us know and it will be included in the next release!

How do I know if I have a Creality v4.5.2 or v4.5.3 motherboard?

I have a v1.1-ERA motherboard. What firmware do I flash?

According to Creality the v1.1-ERA motherboard is electrically compatible with the v4.5.3 motherboard, so you can probably flash the v4.5.3 firmware.

I don't want to open my printer. What happens if I install the firmware for the v4.5.3 motherboard on my v4.5.2 motherboard

No smoke - or at least, not due to the firmware. However, during homing the printer won't be able to read the optical sensor on the gantry. So it won't know when to listen to the strain gauge and drive the nozzle into the print bed.

Does it matter if I flash the touch screen or motherboard firmware first?

No - you can do it in either order. Though, I advise to flash the touch screen first.

I'm having trouble flashing the touch screen firmware / things aren't working / I'm seeing garbled or missing text

Try reflashing your touch screen firmware. Read the flashing instructions carefully. The DWIN stock touch screen is very picky when it comes to SD cards. Sorry, we nor Creality can't change this.

After flashing the touch screen it only shows a black display

This has occurred to some users while upgrading to either official or community firmware, but it is unclear why this happens.

Make sure you haven't accidentally shorted the PCB of the touch screen when you attempted to flash it. Because the DWIN touch screen uses SRAM, it takes a while for the error condition to clear. Turn off the printer for 5 minutes or more and try reflashing the touch screen.

I have leveling issues / my prints don't stick to the bed

Your Z-offset isn't the same as with a previous firmware due to leveling accuracy improvements. Also try cleaning your bed, you may have touched it when flashing the touch screen.

My nozzle is driven into the bed

Ensure the optical sensor is properly connected. You can verify this by running command M119 from a serial monitor, blocking the optical sensor, and running the command again. You should see a difference in the output.

A previous release of the community firmware was (incorrectly) tolerant to this sensor being connected incorrectly. If your sensor is broken, build the firmware yourself with the option '#define PROBE_ACTIVATION_SWITCH` commented out.

My printer reboots when printing (Creality v4.5.2 boards)

Make sure your SD card isn't corrupt. Also some v4.5.2 boards do not like some types of SD cards.

A small number of v4.5.2 boards also get overloaded by the more features that are enabled by the firmware. For most boards it isn't an issue, but some particular v4.5.2 boards are unstable. Nothing you can do, stock firmware for you only - or upgrade to a v4.5.3 or a BigTreeTech SKR CR6 board.

You can also try CF[version]-cr6-se-v4.5.2-mb-no-watchdog-[date].zip firmware, but be aware: if the firmware would freeze then there is nothing that prevents the printer from overheating. Use with caution!

The temperatures go up/down/up/down while bed leveling

That is by design to improve bed leveling accuracy. Turn it off by disabling "Better accuracy" in the leveling settings (not recommended).

@Sebazzz - If it is now possible to make “Probe with Heaters Off” configurable from the new ABL settings menu, could this be an option on the Control menu, impacting all probe operations? Or is this a neat trick that only affects ABL?

Sebazzz commented 3 years ago

It involves all probe operations, so homing too, but there is no space in the control menu until we take a serious look at #121

Thinkersbluff commented 3 years ago

Understood. I have some ideas on that score, too.

Updated the release notes. Included a part of the beta 5 release notes as well.

Some users may appreciate a pointer to this CNC Kitchen Youtube video, to help them make sense of the advice, "Try playing with the maximum resolution and maximum deviation settings in your slicing profile."

"This release of the touch screen firmware comes with a new version of DGUS OS (the underlying operating system of the touch screen) to fix text rendering issues."

Did this get rolled back? I don't see any change to the OS filenames. Ref https://github.com/CR6Community/CR-6-touchscreen/issues/30

Compared to the stock Creality firmware. I shall clarify it.

Thinkersbluff commented 3 years ago

I find the "Restore" defaults a bit confusing on the retraction override screen.

Sebazzz commented 3 years ago

makes the head pause each time it comes back down to the print, while the nozzle pressure is restored

Sorry, that is a feature (Marlin feature that is).

Makes it impossible to set a matching speed

Why?

I hesitate each time I see Restore distance of 0mm, thinking, "if the Restore speed controls bringing the filament back into the nozzle, might the filament stay retracted if I have a value of zero here?"

What do you propose? It is the same settings as these slicer settings:

Thinkersbluff commented 3 years ago

Makes it impossible to set a matching speed

Why?

On my system, these speeds only change in increments of 5mm/sec. With an initial difference of 8mm/sec between the two, I can not make them match each other. I don’t understand why a default value is a “feature”.
It would make more sense to me if the “Restore speed” was labelled “Prime Speed” and if it was defaulted to the same value as the Retraction speed, because I only use Cura.

What do you propose? It is the same settings as these slicer settings:

It is unfortunate that all slicers do not standardize on the same terminology. If the label was “Extra Prime Amount” I think it would be more clear what will happen with a non-zero value.

Selfishly, perhaps, I recommend standardizing on Cura terminology and default settings when implementing “slicer override” settings. At least that way, users who use Cura are better able to correctly guess what each control does, the release notes can explain the equivalent settings in other popular slicers, like S3D, PrusaSlicer, Slic3r, SuperSlicer, etc..

Sebazzz commented 3 years ago

@Thinkersbluff Please open a separate issue for clarifying the terminology. This needs some graphics work.

Just a small hint regarding #208

Would you mind to add a note, that this feature will be usable with Cura Release 4.9, too? This seems to be implemented in https://github.com/Ultimaker/Cura/pull/8403

This may help people like me to not start on implementing this for Cura because it will be available soon 😆
