I used the standard BSS138 level shift-er to connect the ATMega to the RPI’s hardware serial port.

Thanks for the feedback. Drop-box tend to disable the download if the daily download bandwidth has been exceeded. I am looking for more similar services but have not found any viable ones yet. Does anyone have suggestions on this?

do you have any other download source for the Raspberry Pi bCNC Image as it is not possible to download it via DropBox any more.
That would be very nice!

Im curious how you made the serial connection between the RPi and the Nano, using the nanos pins instead of the usb connector. Im thinking of connecting a nano to a STM32f7, making basicly a hat/shield or adapting an existing board to do that.

would be great with some insight. I find that making a UI on stm32f7 and attaching a grbl arduino nano to that would be a good compact solution.. if i could figure out how i would access the pins (thats why im tinkering with the idea of taking an existing arduino shield)

[…] der Protoneer Homepage gibt es ein fertig installiertes Raspbian Image. Darauf ist der Serielle Treiber schon eingerichtet […]

They are actually included in the kit. They are the standard 3.5mm kind.

Just ordered one of these HATs… looking forward to it. Do you have a link to the correct Molex connectors for the Stepper Ports?

With a little bit of modification,yes. The Board is only connected to the first 5×2 pins and the SPI pins are not used at all.

Yes, that is correct and needs to be done for each axis.

Hi, I was looking for this a long time, you use serial port to communicate with arduino, and the spi channel can be used?
Its for this type of display: http://www.sainsmart.com/raspberry-pi/sainsmart-9-inch-tft-lcd-800-480-touch-screen-display-for-raspberry-pi-2-b-b.html
this uses spi to control the touch screen.

best regards

For limit switchs can I use like this?

___/|____/|____ X/Y/Z lim
|____________ GND

ok thanks for the repply….

Yes… It works with Raspberry Pi B+ (Version 1)

Can I use the raspberry pi B?
I don’t have any raspberry pi 2 B

Thanks Bertus! Did as per the instructions and everything is working fine!

The web interface seems promising as well, now to actually build a CNC…

Cheers,
Vasken

Have a look at the wiki-Page http://wiki.protoneer.co.nz/Raspberry_Pi_CNC. There is a link to enabling the onboard Serail port of the Raspberry Pi - > http://www.hobbytronics.co.uk/raspberry-pi-serial-port I am still working on a tutorial to install my home grown version of GRBL-Web... Keep an eye on this space. bCNC is the recommended interface and I have created and RPI image for it as per the Wiki page.

Hey Bertus,

I’ve ordered and received the CNC hat. It’s really nice!

I was able to get the Universal Gcode Sender program to run on the RPi, but I’m not able to get it to communicate with the Arduino.

How do you set it up so that the RPi looks on its GPIO pins for an Arduino instead of a COM port?

Also, is there a tutorial on how to install and use your web-based solution shown above?

Thanks,
Vasken

Hi.. The Nano is preloaded with GRBL 0.9 and the code is available from https://github.com/grbl/grbl

I have order your pi hat and waiting on it, My question is the arduino nano using the code as the arduino cnc shield, if not can I get the source in case I need to replace the nano in the future
