I will Order some pcbs and can Order some for Europe with all SMT components! Please upvote the Post If you want one!

Would supply the Board without Blackpill and Display!

Great Work!!!!!!

PCB is Ready. Please Upvote this Post so i can see how many i will order!

Price should be about 4 € + Shipping

Then you only need

• ESP32 (https://arduino-projekte.info/wemos-lolin32/) This one got the Battery circuit onboard. I added a switch to the PCB if you want to turn off the RepPanel with the Battery
• The display.
  *2x20 Pin Male Connector ( Thinking about including it)

If anyone want I made an accelerometer for using with RRF. You can choose between 3.3V or 5V.

40 are in stock.

4€ without connectors (you can use JST or Molex KK or every other 2.54mm connector)
6€ with jst connectors

shipping europe and worldwide 4€ untracked 7€ tracked

Quick and Dirty Tutorial.

Sometimes i ve got fans which are not fully controlable. E.g. only 100 percent works. Or at 20% there is Not enought airflow Like in the datasheet. Etc.

Even changeing the frequency in M950 does not Help. In an old thread @dc42 mentioned using a Low Pass Filter and setting the frequency to 65535.

So i Made a little PCB for it

Works good. I have some in spare. Populated and Not populated.

Hello i am in the process of making a small Production run based on @DIY-O-Sphere schematic. IT will be Board which will be directly olugged Into the Mini;)

Here is a WiP FreeCAD Path PP.

some drawbacks

• Toolchange is always on. So it will always write the T paramter of the tool. If you dont have a toolchanger and want to change tools give the Tool the same number in Path You can now turn the TC on and off with OUTPUT_TOOL_CHANGE = True or OUTPUT_TOOL_CHANGE = False. This command can be given to FreeCAD without the need of modifying the rrf_post.py

• Tool start with number 1. A tool with T0 is not possible.

if you want to add a special command before every Toolchange you can do this by modify the rrf_post.py by changing

TOOL_CHANGE = ''''''            # Tool Change commands will be inserted

to

TOOL_CHANGE = '''G333'''            # Tool Change commands will be inserted

and just FYI

In RepRapFirmware 2.03 and later, if you try to execute a G- or M-command that RRF does not implement, it will execute a system macro of that name if it exists. For example, if you send G40 then it will execute /sys/G40.g if it exists; and if you send M48 then it will execute /sys/M48.g if it exists. So you can script any custom Gcodes that you need. See https://forum.duet3d.com/topic/14930/m7-... for an example.

rrf_post.py

I just saw that PS added the option to call the dimensions of the print via expressions. So now it is easy to set the M557 for each print automaticly

just insert

M557 X{first_layer_print_min[0]}:{first_layer_print_max[0]} Y{first_layer_print_min[1]}:{first_layer_print_max[1]} S8

in your startcode before G28 and mesh of course

Keep in mind that the M557 stays active till the next print

Dont know if its more hardware or software, but i like the concept of this:

Would be a nice addition to a toolboard or for the smart effector. See the link;)

If more than 10 people want an adapter in Europe i would make some! Best

Merged into main freeCAD. To use this you have to use the weekly build till freeCAD will release 0.20

P-C-R opened this pull request in FreeCAD/FreeCAD

closed Path | RRF (RepRapFirmware | Duet Boards) PP #5228

Tested the PCB today. Works great.

Have 2 more of the Prototypen!
Will give it away for shipping. You only need the Pi. I will include connectors

Best

And yes i knew the CSI connector... Next Revision will fix it.

@Chriss

nice review i found

@pcr

@pcr bugfix 20211115

https://www.raspberrypi.com/products/raspberry-pi-zero-2-w/

now it should be possible to run DSF with the Pi Zero

@pcr

The adapters are here and they work. I tested it with the classic Display, the BTT 35 and the BTT 70.

Please PN if you want one! You can choose between a plugin type or a "extension" one For plugin see the image above

@pcr

@leckietech you could write a little bash script with

made a little videos how to install it. Mainly for my own reference later
