Smoothieware support

[tritao]

Hey, first of all thanks for your work on this nice piece of software.

Do you have any plans on adding support for Smoothieware to the software?

[cheton]

Smoothieware is similar to Grbl, I think that is not difficult to add Smoothieware support to the cnc software. I will get a 4XC SmoothieBoard for protocol testing some other time.

Ref.
vlachoudis/bCNC#143
winder/Universal-G-Code-Sender#204

I wonder if @arthurwolf could help out here with a board to help you test.

If not, and given your location, you could check out the MKS SBase, which is compatible with Smoothieware and ships from China.

If it's an issue, let me know and I'll order one for you.

[arthurwolf]

Hey !

Smoothie is very similar to grbl if you use the CNC build, and add in config : 
grbl_mode true

I can give you a discount, or send you a broken board ( that will still be able to communicate ) if you want.

Cheers :)

[cheton]

Thank you for your information. I will make a purchase for the SmoothieBoard (or MKS SBase v1.3 from China) and then start to work out.

Just tried to connect to Smoothieware as suggested by @arthurwolf, with the firmware compiled with CNC=1 which puts it in Grbl-compatible mode.

The output seems more compatible with what cnc expects, but there's still some problems.

One issue is that the Axes widget never unlocks itself even after the homing command, which homes the machine correctly. But the unlock button, which sends $X, never gets any reply from the board.

[cheton]

Thank you for the information. Just received my SmoothieBoard, I will give it a try in the next few days.

[tritao]

Thanks for the help.

After some more testing, the board does send the response to $X, it's some problem processing the responses.

[cheton]

The command execution will be blocked by a readiness check until it received a Grbl startup line
Grbl 1.1d ['$' for help]:

https://github.com/cheton/cnc/blob/v1.8.5/src/app/controllers/Grbl/GrblController.js#L233-L252

this.grbl.on('startup', (res) => {
    this.emitAll('serialport:read', res.raw);

    if (!this.ready) {
        // View Grbl settings
        this.feeder.feed({ line: '$$' });

        // View startup blocks
        this.feeder.feed({ line: '$N' });

        if (!this.feeder.isPending()) {
            this.feeder.next();
        }
    }

    this.ready = true;
    this.queryResponse.status = false;
    this.queryResponse.parserstate = false;
    this.queryResponse.parserstateEnd = false;
});

I can add a piece of code to detect Smoothie that can work with current Grbl controller.

The full support for Smoothieware, including a Smoothie widget, might be available in the 1.9.0 release.

[cheton]

Added preliminary support for Smoothieware in the 1.8.6 release. Stability is not guaranteed, but it's worth a try!

[tritao]

Awesome, will do some testing and let you know.

Hi @arthurwolf,

I found an issue while trying to stop streaming a G-code program to Smoothie, the status report (?) may report unusual work position with uncertain offsets.

The steps to reproduce:
Step 1. Streaming a G-code program to Smoothie
Step 2. Send ! and ctrl-x to feed hold and reset
Step 3. Send $X to unlock an Alarm state
Step 4. Run step 1 again

After taking several tries, I found that Smoothieware lost its work position in status report, but this never happen in Grbl.

May I know if I made something wrong while trying to recover an alarm state?

[arthurwolf]

Hey. As far as I know, once Smoothie goes into Alarm state, it's not expected to do anything right, and should be fully reset before being used again @wolfmanjm might have more details. Cheers.
