[…] 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. […]

Hi Bertus.
It looks like it was a bad driver.

Hi Bertus. Here’s what I have and what;s going on. Windows Vista 32 bit, GRBL 0.9, Ver 3 CNC shield, clone “A” to “Y” axis, set VREF for .8a, 3.75 degree steppers on A4988 drivers per Pololou directions. What happens is the “A” & “Y” do not turn the same. They shudder and one may turn 3/4 turn, and then the other. “X” & “Z” will shudder and whine also. I’ve even reset GRBL for 96 steps per mm from the default, swapped motors, swapped drivers, still they shudder and whine and don’t turn the same. It was no different with GRBL 8. Any thoughts or ideas where I need to go next? If they turn for an extended period, they all run smooth but just on start and stop.

Hi. GRBL 0.9i has a small change in pin configuration(PWM spindle). Z-limit and Spindle enable pins swapped. But that should not affect the A5 probe pin. Are you using the the A5 pin or the SCL pin? What is your Probe setting($6)? If you are not using Probe you can set $6=1 and add a stronger Pull-up resistor to get rid of any noise.

Hi Bertus, I´m using UNO, grbl 0.9i and your board V3.
Is there an updated pin map? I keep getting a ‘probe triggered’ error.
Thanks!

Hi Rodney, The V3 does not have the Probe specially exposed.(The next board to be released soon will have it) But if you look at the top right of the shield there is a 4x2pin header and one of them is labeled as SCL. That is the A5/Probe pin on the UNO.

I’m very new to this CNC stuff and would like your help.
I’m using your V3 shield and I’m starting to wire everything up and all of that looks straight forward but is there a way to use a probe with your shield??? If so how do I do it as I don’t see a pin for it.

Thanks

Rodney

At this stage GRBl only supports 3 axes. But its planned to add more. The other option is to write your own software that implements the 4th axis.

Hello!
I have Arduino UNO & cnc sheildv 3.0 with 4 axis
I building cnc foam cutter, how to choose the firmware to 4 axes compatible with GRBL?

Have a look at http://blog.protoneer.co.nz/configuring-grbl-arduino-based-cnc-controller/
Calibrating the machine takes time and its a set and test process. 😉

hi!, How do i configure my GRBL?. I have stepper motor Em 257 and Em 462.I do not know what speed i put. Sorry for my English. regards.

Hi Sofia,

My Spanish is not good at all, could you please translate re-ask your question in English?

hola!Bertus!he descargado todo tal cual lo menciona en la guia pero no se como configurar mi grbl. tengo motores de impresora de 12V,pasos 7,5°, no se las velocidades que debo poner (seria 48??) .
Disculpa las molestias!saludos .

As per my previous can you confirm that GRBL is actually functioning? Might be worth sending me an picture of your setup.. info at protoneer dot co dot nz

hello..i am having issues with the output.
this is what i have done so far:
1- downloaded hex file from https://github.com/grbl/grbl/downloads
2- using Xloader, i have uploaded the hex file.
3- downloaded grbl controller.
Now when see the outputs from arduino uno pins, except pin 2,3,4 and 5, all pins are consistently high, while these 4 are consistently low.
i need to know where i am making a mistake.
The above mentioned steps are what exactly i have done not even a single thing different.
Please help…
Thanks

Hi. At this stage GRBl(g-Code enterpeter) does not support more than 3 axes. To extend the axes number above you 3 you will have to modify the code to allow this. Regards.

Hi Gatien,

Thanks for the really nice video on how to use Sketch-up in your CNC workflow.

I think your trouble is with the 5v power source. Easydriver motor controller drivers need more than 5V to work. The input voltage going into the stepper driver and the voltage that the stepper is rated is not the same measurement. Regards.
