Make Sure your Offline Controller is Physically Disconnected from Your CNC: This is a very frequent cause for "Port Opened" as your CNC can not connect to more than one device at a time. Once you disconnect the offline controller, disconnect and re-connect your CNC to your computer if Cand...

while never overflowing it. It maximizes Grbl's performance by keeping the look-ahead planner buffer full by better utilizing the bi-directional data flow of the serial port, and it's fairly simple to implement as ourstream.pyscript illustrates. We have stress-tested this character-counting prot...
arduino due port YesterdayI tested grbl v0.9 cide ported to arduino due. I have 7" lcd with touch and SD card file system. Now is ported only x,y,z axes. No spindle, limit control, no uart. First speed test config define DEFAULT_X_STEPS_PER_MM 3200.0...

Here we will describe two different streaming methods for Grbl GUIs. One of the main problems with streaming to Grbl is the USB port itself. Arduinos and most all microcontrollers use a USB-to-serial converter chip that, at times, behaves strangely and not typically how you'd expect, like...
My feeling is to start with the simplest implementation, namely, an arduino with an SD card reader that reads a file found in the root directory named 'mygcode.g' and streams it out to the controller over a serial port at a predetermined baud rate/etc. Issue 1: Since you cannot connec...
