SinapTec AT328.02 is a 3D FDM printer controller board of ultra low cost, Based on Arduino Nano

SinapTec_AT328.02_-_Foto.jpg

    1 Arduino Nano socket. 

    4 Pololus sockets (X,Y,Z y E) 

    3 Line in for X_MIN, Y_MIN and Z_MIN endstops. 

    2 Line in for Hotend and heated bed sensors. 

    3 Mosfets outputs for Heater, Fan and Bed (this last with independent power supply).

Thinkgs to be needed to do:

* Make the configuration file and push it to the experimental branch of tea cup.
* We are developing some Voronoi PCB
* Put more information on the wiki
* Add more photograph of the board
* More Stuff

Yupp, good idea!

High current tracks like 12/24V for the steppers and corresponding GND are a bit thin for my taste. Here's a track width calculator: [www.circuitcalculator.com]

Would you mind to fully integrate this into official Teacup? I've seen you dropped a config.h, but unfortunately the use of this file in this way is deprecated already in favour of Configtool. With full integration we can both take advantage of each other, you get our work and we get yours.

Yes its my idea to develop the config for the new version of teacup . the issue was that I did try to run the tool py under windows an I got error so I need to install lunix in a VM an do the test.

Thanks for the report. Configtool should definitely work under Windows (and Mac OS X). Prerequisites are about the same as those of Pronterface.

Could you copy the error message (or whatever happened)? Thanks.

ImportError: No module named wx

Another thing is, your Python might default to Python3, which can't be supported, because there's no wxPython for Python3. Typing "python2 configtool.py" should help.

And thanks to your error report we managed to add two commits giving better hints: [github.com]

  To deal with this, Teacup adapts homing movement speeds to what your
  endstops can deal with. The higher the allowed acceleration ( = deceleration,
  see #define ACCELERATION) and the more clearance the endstop comes with,
  the faster Teacup will do homing movements.

  Set here how many micrometers (mm * 1000) your endstop allows the carriage
  to overshoot the trigger point. Typically 1000 or 2000 for mechanical
  endstops, more for optical ones. You can set it to zero, in which case

  device has the index 0 (zero).

  Set 'pwm' to ...
    1  for using PWM on a PWM-able pin and on/off on other pins.
    0  for using on/off on a PWM-able pin, too.

  Using PWM usually gives smoother temperature control but can conflict
  with slow switches, like solid state relays. PWM frequency can be
  influenced globally with FAST_PWM, see below.

enif, any chance we can have your DIY Tiny OLED I2C full graphics controller connected to this board

Yes, that would be nice, but I fully agree with tatubias that this is probably asking too much from the Nano - not enough pins and probably also not enough free memory for the graphics library either...

Now does teacup support i2c ? Do we have enough space to enable i2c and the library for the display?

Typical for such small controllers is to connect them to a small PC, like a RaspPi. Then you get all the glory, including a web interface, touchscreen, slicer, standalone operations and whatnot.

There is some support for displays on the delta branch. Not integrated, yet, currently Configtool has priority.

just want to know if there is a possibility of using the arduino micro instead of the nano. since it has more pins, things like lcd and what not
