Although the form factor is the same for the Mega and DUE, the pinouts are different between g2 and 4 axis version of GRBL which is what causes the issues. Comparing the g2 DUE pinout with the Mega Shield pinout , there are quite a few differences in the pin functions/assignments. There may be some ...

All of my products were designed around GRBL 1.1f . They'll likely work with 1.1h but I have not tested it and don't want to point people towards potential problems. Also, none support the self-squaring gantry feature - take the time to build a solid and square machine rather than relying on tricks ...

The probe port on the Mega Lite has a GND and signal connection. The signal is marked with the dot (near the E in probe). Connect the black wire near the P, the blue wire near the E, and the red wire to 5V and it should work.

In short, will the Grblduino Uno V2 Shield work with Grbl 1.1h (dual y axis and squaring) without any editing to Grbl? Nope, these boards are built on GRBL 1.1f and I haven't done any research into the work needed to be compatible with the newer version. Additionally, these boards don't, to the bes...

Hi got a silly question for you. So I bought the https://www.amazon.com/gp/product/B06XCVY3GM/ref=ppx_yo_dt_b_asin_title_o06_s00?ie=UTF8&psc=1 So I think I might of borked the converter I reversed the PWM 5vdc lead from mega to the converter. Since there is a Opti coupler on it would the 5 volt...

The Arduino Uno products use the standard GRBL 1.1 pinout which has been in use for several years now. It is compatible with any other standard G code sender or GRBL compatible software. The underlying issue is estlcam runs it's own custom firmware rather than interface with GRBL and it is based on ...

The complete pin out can be seen here.

D11 is connected to the spindle speed terminal and the signal pin is the 5th one just like you expect. The other pin in that pair is a ground connection.

I'm not super familiar with 3 wire limit switches so this is a little bit speculation and will require a bit of experimentation. The switches have Signal, V+, and GND. The hard part will be getting 5v - it'll require soldering a wire to the 5v pin on the shield (5th pin from the left on the bottom f...

I am thinking that the mega is not producing 10VDC but a PWM signal completely different right? 2 diff signals? My spindle analog 0-10VDC, mega is digital. I did try to see if there was any voltage from the port "Spindle Enabled, Speed and Direction" was producing but nothing. Your assump...

Some drivers are enabled by default and others need the connection. For the limit switch connections, there is one wire each for signal and a common ground. They share the ground terminal at the bottom of the board with the +5v input. For the connections to the controller, you'll only use one of the...
