Simple relay control... or not?

Nightowl

@alankilian
Yep. Just keep an eye out for a big cloud of smoke in SW England. If there is one, it didn't work

dc42

@nightowl999 have you considered using the Laser/VFD output to drive the relay module? It provides a 5V signal.

Nightowl

My intention is to 'upgrade' to a milling motor in the not too distant future, @dc42, so I was going to leave the Laser/VFD output for that.

Doing it this way for now will support both my router and dust collector, and just the dust collector when I've saved enough for the MM.

Nightowl

@alankilian Ah, perhaps not.

I think I've missed something because, when I send the M3 code from the Console, I get the error:

M3
Error: M3: No P parameter and no active tool with spindle.

Am I supposed to configure this elsewhere in the config.g file?

Thank you

alankilian

@nightowl999

From the GCODE page:

"It is an error if there is no tool active or the active tool does not have a spindle assigned and there is no P parameter provided to define which spindle this should be applied to."

Maybe you just need to select a tool using a T command? REFERENCE

Or you need to define a tool using M563 ?

Nightowl

@alankilian Oops, well I haven't defined a tool, so that's probably a good starting point!

Would it just be a case of adding a single line like this before the M950 line, then:

M563 P0 R0 S"Makita" ; assign spindle 0 to tool 0 and name it Makita

Thank you

Nightowl

I'm still having some difficulty getting this 'simple' thing to work, but I have made some progress, thanks to you guys on here!

I've revisited my config.g file and come up with this to configure the relay:

; Makita and relay configuration
M950 R0 C"out1+out8" ; enable router relay on out8
M563 P0 S"Makita" R0 ; assign spindle 0 to tool 0 and name it Makita
T0 ; select tool 0

Now, when entering M3 in the command line I don't any errors at all - but the relay doesn't activate, so nothing happens.

I know I'm getting there, but I must have missed something!

Any further help would be appreciated.

Thank you

@nightowl999 try adding L1 to the M950 and then sending M3 S1 rather than just M3

droftarts

@nightowl999 Apologies if you have already stated this, I can't see it in the thread, but what firmware version are you on? Send M115 and post the response. Earlier versions of RRF 3.x dealt with assigning spindle outputs differently. See https://docs.duet3d.com/en/User_manual/Reference/Gcodes/M453

Hi @droftarts.
The result is...
m115
FIRMWARE_NAME: RepRapFirmware for Duet 3 MB6HC FIRMWARE_VERSION: 3.4.0 ELECTRONICS: Duet 3 MB6HC v1.01 or later FIRMWARE_DATE: 2022-03-15 18:57:26

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

jay_s_uk

@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

Nightowl

@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

alankilian

@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.
