I am using a Raspberry Pi, latest Raspbian etc. (want to install on this one as it is already setup for my uses, hence why not using the pre-made image ;))

installation problem grblweb raspberry pi 3

i have flashed my shapeoko 2 with grbl 09. i was working with grblweb but now grblweb can still see the machine but cannot communicate with it. Any idea why this is happening. cheers

Option to load Files from the local disk of the raspberry, load/store settings to the raspberry

Very cool Project!
I will use it in my new Laserengraver build.

It would be very cool to be able to load gcode or svg files from the local disc of the rasbberry as well.
storing and loading settings from the local raspberry disc would be very useful as well.

Raspberry PI 4 -- FATAL ERROR: Ineffective mark-compacts near heap limit Allocation failed - JavaScript heap out of memory

Hello,

I am trying to use GrblWeb on a Raspberry Pi 4b 4GB, and I am having issues. The following is the console output on the terminal. The key issue is the JavaScript heap out of memory failure that crashes the app. Once this happens, I have to re-home in order to proceed, and it happens after just a few minutes. I have tried with Ubuntu 18.04, 19.10, 20.04. Raspberry PI OS 64 bit and Raspberry Pi OS 32 bit, all with the same issue. Current node.js version is v10.21.0, but I have also tried it with v12 and v14 with the same issue. For troubleshooting, I disabled the '?' polling because i thought that the hits on the sockets.emit may be the memory leak, but that also did not resolve the issue. I do have the camera, and had set up the mjpg stream (which was working), but was still having this issue below even with the camera set up and operating properly.

grbl v1.1 support

Any chance that grblWeb will support the new grbl v1.1 protocol soon?

Please add hardware requirements to the README.md

There are multiple raspberry pi versions in the market, and some compatible hardwares like orange pi. Could you add some minimum and recommended hardware requirement to run grblweb?

e.g, Raspberry 1/2/3/4, RPI Zero, RPI Zero W, Orange PI, etc.
They have different versions with different memory, does it work with 512MB or at least 1G?

Interface look different, without the X,Y,Z control

Why is my interface looks different with yours? It doesnt have the X,Y and Z control.

Also, after sending Gcode to CNC, there is no response, coming with a fileServer error. What can I do with it?

Thank you in advanced.

node package.json

It would be nice to have a package.json file to automatically load the correct version of the dependencies with a simple "npm install".

Thanks!

Add script that can install/reinstall Grbl on the GrblPi

Hi

Just an enhancement request

I created a script that will download and install dependencies as well as Grbl 0.8 9600 hex and then upload it to the ATmega on our GrblPi board

Can easilly modify it to take parameters maybe like picking GrblPi/Uno/etc and changing the upload baud rate accordingly. I am using the Duemilanove bootloader on the GrblPi as the 57600 makes for a more reliable upload with level shifted serial but you can use same script to upload to say an Uno at -P /dev/ttyACM0 -b 115200

I figure adding this as a wrapper in your GrblWeb will be a cool feature to upload (or reupload) firmware from within GrblWeb - making deployment and maintenance easier as well?

Lasersaur did a similar thing in lasaurapp and I use the firmware upload from there quite often

Grblweb on CNC laser engraver

Is it possible to use Grblweb to control a CNC laser engraver?

Externally hosted libraries means no internet-less access

Tried implementing GrblWeb on a GrblPi at hitemp.co.za's factory today (replacing the chinese electronics) - struck a snag. Bootstrap and JQuery libraries are hosted off-device so hooking a laptop up to the CNC means it didn't "just work"

We had to pull in a lan cable to get internet to the laptop.

Maybe add?

start and stop grblweb

how to start and stop grblweb? Where are the startup script?

Thanks

Change of tools

Hi,

how are you supposed to perform a tool change with GRBLweb?

I have M05 and M00 in my .nc file, then the machine halts, however no controls (eg. to lift Z) are possible.
Also I am not able to manually send commands.

Support for newer models of Raspberry Pi

Are there plans to support the Pi2 Model B or more recent builds of raspbian?

npm install fails

Hello,

I tried to execute npm install and it fails:

Could you help me with this? I tried installing the node-pre-gyp, but that doesn't help.

/dev/ttyAMA0 not showing up in Serial port list after making available

===Procedure to replicate issue===
Follow standard process to free up Raspberry pi serial port on your Pi Image (Procedure below)
Reboot to take effect

===Expected outcome: ===
/dev/ttyAMA0 (Broadcom UART) available in list

===Actual Outcome:===
Serial port dropdown only shows "Select a Serial port"

Procedure to make /dev/AMA0 available: Tested by using screen /dev/ttyAMA0 9600 and can communicate fine with Grbl on the GrblPi Shield, send commands, list settings etc from Screen. Node is just not detecting it

Firstly, the kernel will use the port as controlled by kernel command line contained in /boot/cmdline.txt. The file will look something like this:

dwc_otg.lpm_enable=0 console=ttyAMA0,115200 kgdboc=ttyAMA0,115200 console=tty1 root=/dev/mmcblk0p2 rootfstype=ext4 elevator=deadline rootwait

The console keyword outputs messages during boot, and the kgdboc keyword enables kernel debugging. You will need to remove all references to ttyAMA0. So, for the example above /boot/cmdline.txt, should contain:

dwc_otg.lpm_enable=0 console=tty1 root=/dev/mmcblk0p2 rootfstype=ext4 elevator=deadline rootwait

You must be root to edit this (e.g. use sudo nano /boot/cmdline.txt). Be careful doing this, as a faulty command line can prevent the system booting.

Secondly, after booting, a login prompt appears on the serial port. This is controlled by the following lines in /etc/inittab:

Spawn a getty on Raspberry Pi serial line

T0:23:respawn:/sbin/getty -L ttyAMA0 115200 vt100

You will need to edit this file to comment out the second line, i.e.

T0:23:respawn:/sbin/getty -L ttyAMA0 115200 vt100

Finally you will need to reboot the Pi for the new settings to take effect. Once this is done, you can use /dev/ttyAMA0 like any normal linux serial port, and you wont get any unwanted traffic confusing the attached devices. )

Preview Window

Hi,

I have not been able yet to produce one GCode file that shows up in the preview. In the Result window I regularly receive the following:

--------------New Gcode Loaded--------------
Min Dimensions X: 100000 Y: 100000 Z: 100000
Max Dimensions X: -100000 Y: -100000 Z: -100000

Total Dimensions X: -200000 Y: -200000 Z: -200000

Which are definitely not the dimensions of my GCode. I would be happy to supply sample code.

nodejs serialport 1.4 is not compiling properly

Hi Andrew

nodejs serialport version 1.4.x is not compiling when doing a fresh 'npm install' (their issue) - I have changed version in package.json to "serialport" : "4.x" and voilá

BTW this is a great-great package, interesting solutions throughout the code, and millcrum is fantastic. If you want a hand on future developments drop a msg

Best,

Got error: connect ECONNREFUSED 127.0.0.1:8080 not enabling webcam

Using node js on window 10
trying to run grblweb

config.webPort = 85;
config.serialBaudRate = 115200;
config.usettyAMA0 = 1;
// expects a webcam stream from mjpg_streamer
config.webcamPort = 8080;

my configurations

Got error: connect ECONNREFUSED 127.0.0.1:8080 not enabling webcam

npm install fails

package.json has no attributes "name", only:
{ "dependencies" :
{ "node-static" : "0.7.x"
, "serialport" : "1.4.x"
, "socket.io" : "1.0.x"
}
}

So it fails with:

Draggable jog interface is not good for fine control

The draggable jog interface is OK for coarse movements, but relatively tricky for moving the head to a precise start position compared to the old buttons.

It would be nice to have an option to choose which UI to present.

The best I've used for this is the pronterface UI for 3D printing

OS X serial connection, check permissions on /dev/cu.Bluetooth-Modem

I'm trying to run this in OS X and noticed that the server.js script loops over all of the available serial connections. This happens before the web server even gets up and running. On OS X it chokes on the bluetooth devices. I can edit the loop index to start at what ever the USB tty is running on and the script loads fine. I think there just needs to be some error catching when trying to initialize each serial connection. I have been looking into fixing this issue but wanted to make note of it here.
