Re: motor not responding to Gcode sender command

You will need to install the Arduino driver first as per section 4.

If everything is install correct and you hit the reset button or type/sent $, data should returned and displayed on the Gcode sender.

Re: GRBL Freezes while sending a file

Some information that my be helpful... Bypass capacitors ( A.K.A Decoupling capacitors) help remove AC noise from your circuits. (don't use cheap power supplies as they are known to have poor decoupling), Just had a Idea... you could try placing a 4.7uF capacitor (rated at 50V) across the GRBL + and...

Re: Arduino Mega 2560 & RAMPS

You are going down the right direction but the GRBL is more of a “raw” C code then Arduino, So when defining the pin-out you have to define the pin/port as per the chip datasheet. E.g pin 46 (as per Arduino) is realy port L pin 3 http://arduino.cc/en/Hacking/PinMapping2560 http://www.arduino.cc/en/R...

Re: Dual Motors of one driver.

It will work fine, as I have my ShapeOko running of a "GRBLshield" with two motors on one driver.

Re: Magnetic Linear Encoder - pcb/kit

Ejs is correct about there being only 2 external interrupts on the Arduino UNO 328 chip set (its not a coding limitation - its a limitation of the chip) and the reason interrupts are used in the example is because you don't what to miss a change in state as you are basically “counting” gray code to ...

Re: Plug and play wireless serial (with Xbee)

@ LineKernel I don't know what AT command means but I do know what it is, it's data that is send via it normal serial communication but in a special way so when the bluetooth sees the string of data it will action it. For example on a RN-42 bluetooth you send “$$$” to enter the command mode then you...

Re: Plug and play wireless serial (with Xbee)

They should work fine when connected directly to the Arduino (no code change needed), it’s also be ok to connect the power needed for the Bluetooth directly to the Arduino as well. Arduino -------- Bluetooth Pin 0 (RX) --- Pin 2 (TX) Pin 1(TX) ---- Pin 3(RX) 5V ------------- Pin 1 (+5V) Gnd --------...

Re: Dual Motors of one driver.

Hi Guys, Sorry for the delayed response, been investing my time into my primary project/hobby ( http://code.google.com/p/slide-33/ ) which is by the way the reason I got a ShapeOko. The current in the circuit is not halved - as by connecting the motors in parallel you are changing the inductances (l...

Dual Motors of one driver.

I was thinking the other day that I really needed to make a dual motor system for my Y axis because the other side was just "floating" to much for my liking, the first thing that came to mind was Fleming's left had rule because I didn't have any additional drives to drive the motor. So I connected t...

Re: At a total loss, really thought this was gonna be easier

I had a little look into the Buildlog.net shield and it seems the pin-outs are different to the grblshield supplied with the Inventables kit, so you need to make sure your code has the correct pin-outs or funny things may happen. Buildlog.net shield Arduino pin-out are : 2 - X_STEP 3 - X_DIR 4 - Y_S...
