Aha, seems like the axis for the gShield/Due boards are disabled by default.

[xam] x axis mode                 0 [disabled]
[yam] y axis mode                 0 [disabled]
[zam] z axis mode                 0 [disabled]
[aam] a axis mode                 0 [disabled]

Next step, lets see if the steps are being send to the correct pins. 🙂

Ugh. Still can’t get this to work. 🙁

If I build and flash g2core (master branch) using CONFIG=TestV9, then when I issue simple G-Commands they immediately run. eg X/Y/Z position changes (talking logically here, without any stepper drivers/motors hooked up).

For example:

{clear:n}
{"r":{"clear":null},"f":[1,0,11]}

This part seems to work. 🙂

When building and flashing g2core using PLATFORM=DUE BOARD=gShield (as per the PDF), as I’m using a Due board and can hook up the stepper drivers to the pins mentioned in the PDF… simple G-Code commands don’t run. Even with motors (logically) definitely enabled before giving the G-Code commands.

In this second case, the commands are accepted but nothing “runs”. I’ve been reading through all kinds of docs, looking through tonnes of the source… but literally nothing seems to address this. It just seems like there’s something missing to make it “Ok, start now…”.

Any hints?

Took a day longer to get back to this, but on it now. Noticing what seems like a few initial mistakes in the wiki page data, but figured I’d ask here just in case it’s me misunderstanding. 😉

With the “Configuring System Groups” page here:

https://github.com/synthetos/g2/wiki/Configuring-0.99-System-Groups

Under “{hp:n} Hardware Platform”, it has the return values listed as:

{hv:1}  TinyG Xmega series
{hv:2}  Arduino Due G2 (ARM)
{hv:3}  TinyG v9 G2 (ARM)

Should those be hp instead of hv? When manually typing in {hp:n}, the return values I receive start with hp.

On the Power Management page, under “Global Power Management” there is a table with “Setting”, “Description”, “Notes”:

https://github.com/synthetos/g2/wiki/Power-Management#global-power-management-settings

The Notes for both the enable and disable setting list the exact same command to run: {md:0}. That seems wrong. Shouldn’t enable be {me:0}?
