Spindle Control on 6HC

Xamation

@phaedrux @phaedrux in the config file I have not entered any M98 command.
To activate the spindle, after turning on the machine, I make the zero point of all the axes (X,Y,Z) and send the command M3 P0 S1000 through the web interface

@xamation this is my spindle section from my config.

M453 
M950 R0 C"e0heat+e1heat+e2heat" Q100 L6000:24000				; CNC mode and spindle settings

; Tools
M563 P0 R0 S"Spindle"                              				; define tool 0

and i can control the spindle ok using M3 etc.
sending m3 s6000 turns the spindle on at 6000 RPM.

You misunderstand me. What I want you to do is send M98 P"config.g" in the gcode console in DWC and copy and paste the response you get here so we can see if there are any syntax errors in your config.

@phaedrux I solved the promise. I installed the update to version 3.4 and it seems to work. I updated some commands but it reports the error: Error: bad drive number

Can you be more specific? Show us what you changed.

Hi @xamation,

Would you be kind enough to explain why you have three pin names in the M950 line for the spindle like this so I can understand why, please
M950 R0 C"e0heat+e1heat+e2heat" Q100 L6000:24000

I'm very new to 'programming' the Duet3, but I'm wondering if this (which I haven't tested yet because my milling motor hasn't arrived) will work:

; AMB spindle configuration
M950 R0 C"out9" L0:25000 Q1000 ; create spindle with index 0
M563 P1 S"Spindle 1" R0 ; create tool 1 with spindle 0 and name it "Spindle 1"
M453 ; set machine to CNC mode
T1 ; select tool 1
M3 S0
M5 ; stop spindle

Thank you.

@nightowl999 the first pin sets the speed using PWM, second one sets the spindle to forward, 3rd one sets the spindle to reverse

Thanks, @jay_s_uk.

OK, so I'm guessing (assuming everything's configured correctly) the g-code file sends an M3 S2000 command, for example, and the first configured pinout would signal that to the spindle to turn on and run at 2000rpm.

I don't envisage (!) ever using the spindle to rotate in any direction other than its default rotational direction, so I shouldn't need to use the other two pinouts, should I?

@nightowl999 the second pin enables the spindle

@jay_s_uk Got it, thanks.
