A Different Piezo Probe

by rq3

Attached is a description of a very different approach to piezo probing. I have a prototype on my Predator, and it works....frighteningly well.
Just throwing it out there. I don't make them, sell them, or have parts for them. The basic idea is the take away.

Here's a video of the probe in action:

Help!!! Need original Level_Test.gcode

by Juztsacki

Hello Everyone. I just recently got a Anycubic Predator which was working good however, the SD card it came with got corrupted and I lost all gcode files. I restored most of them but am missing the most important one. The Level_test.gcode. Which prints a test print of a target on the bed of the printer. If Anyone has a backup of that gcode. could you please shoot me a link so I can have it.

Marlin 2.0.9.2

by rq3

I was hoping that Marlin would leap to 2.1, but no. Anyway, the latest full release works well on the stock Predator, and you can even use the MarlinUI, rather than the ClassicUI. MarlinUI is a full color touch screen interface. Temperature control seems more stable, as it should, since they finally realized that the Trigorilla Pro uses 12 bit, rather than 10 bit ADC's (thanks to me). In my opinion, it's still not good enough for platinum RTD sensors, but I'm working on that.

Motion control (steppers) seems to have been tightened up a bit, although I have no proof of that, other than M48 reports more realistic and repeatably believable values.

If you do use MarlinUI in configuration.h, you will have to "de-comment" Mesh_Edit_GFX_Overlay in configuration.h to get it to compile. Under ClassicUI, it compiles fine, and seems to work well. Bug report submitted.

Marlin 2.0.7 for the Anycubic Predator

by rq3

Attached is a zip file which will unzip into Marlin 2.0.7 modified for the stock AnyCubic delta Predator using the Chitu Trigorilla Pro 32 bit board and 3.5 inch touch screen. The firmware.bin file in the pio\build\trigorilla_pro folder should directly load onto the board, using a USB cable and the STMicro Demonstrator, if the board jumpers are correctly configured.

Alternatively, you can modify any files you need to, recompile under PlatformIO, and download your new firmware.bin file.

There is no need to physically rotate the display, and the only issue that I am seeing is that perhaps the filament detection logic is reversed. I am looking into that, but you can turn OFF filament detection from the touchscreen, and store that change, as a workaround.

The "Enter" and "Cancel" touch button positions will be swapped left to right, and the previously dark blue enter button will be an easier to see blue, but otherwise the functions are all "normal Marlin".

After updating your Predator to Marlin, you must run a delta calibration and save the changes from the touch screen.

The Marlin GitHub releases change too fast, and too far, especially in the realm of the user interface, for me to keep up with, so this will likely be my last post on this topic for quite a while. If I discover an improvement I'll post, otherwise I'm done for now.

Changing E-Steps on Chitu

by Javimoper

Hi, im running the stock board right now and ive upgraded to a BMG clone, ive been loking around on how i can change de E-steps.
So through cura i send the comands.
-1rst thing ive done is send G1 E100 F100 so it extrudes 100mm
-Im getting a value of 93mm
I dont think the comand values i send in are working correctly because ive changed this value several times (M8011 S) and saving with M8500 and the measurement on extrusion is the same.
Did manage to change the extruding direction.
Any help? is there anything im not doing?
