Simple relay control... or not?

Nightowl

Tried that, @jay_s_uk, but got the following error:

Error: M3: Requested spindle RPM out of range.

I also tried S0, which didn't produce an error, but didn't operate the relay, either

@nightowl999 ok, attempt 2.
Remove the L1 from the M950.
And just send something like M3 S4000 (I know we don't have RPM control)

Nightowl

Well, that worked @jay_s_uk!

jay_s_uk

@nightowl999 great, so any S value should activate the spindle. So just make sure your gcode has that an you'll be fine.
M5 should then turn it off

@jay_s_uk

Yep, S1 doesn't work, but S1000 does.

For some reason, and I haven't done anything but add then remove the L1 you suggested earlier, using just M3 works now!

Nightowl

OK, so I really don't know what's going on here.

AS per my last post, M3 and M5 activated and deactivated the relay.

Since shutting down and restarting the Duet after lunch, M£ doesn't work again - even combining that with an S1000 or S5000 command.

This is very perplexing!

@nightowl999 can you post your full config.g?

I've got a bit of an update on this, but I'm not sure if it's me, the firmware of the machine...

When I first start DWC up and send the "M3" command, this shows green in the Console, but the relay doesn't operate. However, if I send "M3 S5000" this also shows green and the relay does operates. Thereafter, entering just "M3" operates the relay. M5 deactivates the relay.
It sounds like I should be adding an M3 S5000 line somewhere in the config.g file, but wouldn't this operate the relay and, ultimately, the router? I suppose I could follow that with an "M5" line, but it doesn't sound good practice to me!

Thanks

@nightowl999 From the M3 page:

M3 can be called without any parameters and will start the spindle of the current tool turning clockwise at the spindle RPM of that tool.

So I guess you should define a spindle speed for your tool using M568, then select the tool and then do M3 and it should start up.

Give it a try and let us know.
