This sounds like it could be the stepper motor wires being hooked up wrong. have a look at http://blog.protoneer.co.nz/stepper-motors-wiring-up-a-bipolar-stepper-motor/ Have you swapped out the stepper driver as another test?

Restarting the the UNO should display the GRBL version.

Sounds possible if the pins can be readjusted in TinyG.

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

Hi Ron. Have a look at Pololu's design notes on the Fault Pin. https://www.pololu.com/product/2133 They Pololu DRV8825 has a pull-up resistor on the Fault pin and is fine with logic voltage as used on the A4988.

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?

[…] I will use an older version of Sketchup with a plugin for converting faces to SVG format which the g-code interpreter can use. To get the computer to talk to the CNC shield you will need to program the Arduino with this method. […]

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!

Greetings,

You have done a nice job with this board and the instructions. In looking at the schematic I have a concern when using the DRV8825 from Pololu.
The 8825 has a pin labeled nFAULT. This is an open drain output from the 8825. Your board has the pin tied to +5V. If the 8825 signals a fault will this not cause a short of the 5V power and potentially destroy the chip?

Thanks,
Ron Wensley

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)

Question about the CNC Shield and compatibility with Due. The folks at Synthetos are porting TinyG to run on the Arduino Due, and it is compatible with the old 3 axis grblShield.

Would it be possible to run the CNC Shield on Due with the TinyG firmware? I’m thinking it should work, since you are really just extending the Arduino pins to the shield and incorporating the driver circuitry.

Hi!

I’m complete noob in the Grbl word, but not in the Arduino one.
I am trying to connect a CDROM step motor, but can´t manage to have a smooth motion. Each time I send a command it moves but with a lot of hiccups, instead of a nice “ZZZZZZZZZ” noice, I get a “BrrZBrrZBrrZ”, and the motion is not clean.

I assume I might need some jumper somewhere and/or need to setup the Grbl with proper values.

Can anyone assist me?

Ah, In re-reading the article I see the connection of PWM to TTL now, thank you! ( http://www.instructables.com/id/Shapeoko-2-Arduino-UNO-R3-grbl-9g-8bit-Raster-Phot/). However, my shield is not showing the “VER 3.10” stamp near the power supply connector like I see in the picture. (can i upload a picture of my board here?). Also, not sure what version of Grbl is running. does $$ show me the firmware? I’ll have to look tonight when I’m home. Thanks for the reply.

No…. For the PWM Spindle to work they had to change the pin because not all of them support PWM. Coolant pin is for misters and liquid pumps to keep the cutting surfaces cool. The breakout pins on the Left of the shield can be connected to external drivers like the TB6600.

With version 3.10 the Spindle pins has been corrected for GRBL version 0.9. Spindle = P11 and Z-Lim = P13

Are you talking about the PWM? The V3.10 and up boards supports the PWM spindle control out of the box and uses the GRBL 0.9 firmware. All you have to do is connect ground and the spindle pin.(Ensure the Laser Diode is the right way around.) To activate the PWM function set the “S” command to 0-1000. Don’t forget to also use the Spindle commands to switch it on – > M3-5.

Yes… It should be possible via the breakout pins on the left of the shield.
