Hi everyone,

I've converted my Elegoo Giga into a Duet-controlled machine and wondered if someone could help translate the start code that heats only the required beds (there are 4 x 400mm2) ,

Here's my attempt, which at some point seems to override H0 (my heatbed 0) and in DWC where I have four heat beds, H0-H3, Heat bed 0 gets changed so I have two Heat Bed 1s.

@chrishamm

Hi,

I've recently installed the Motion Plugin and it all went well to start until I ran into the same problem as @kiendeleo . I've plugged in an external USB and restarted after reading this post (running 3.5.2) and for whatever reason it looks like it's using up the SD card space. I've had a look through the .conf file to see if I could get it to not save images and while it looks like all the settings are turned to 'off' I'm still running into the low disk space issue and failing prints. Any advice would be welcome.

Thanks

Nate

@gloomyandy Thanks, you're right, I was trying to use M671 incorrectly I think.

It is probably easiest to just write a macro for this and use that with the bed-level screw positions I've got.

-N

@droftarts

Thanks, had a look at M671 and it should've been obvious that there is a 4-point limitation.

For some reason, I thought I had it working on my long print bed before as a bed-leveling screw array versus a more modern pivot point definition. if that makes sense.

-N

Hi,

Previously I had a manual bed level array that had 10 positions for the Y Axis bed leveling screws (code below is now

M671 X75:450:825 Y0:320:635:950:1265:1585:1950:2250 P0.5    

And running 3.5.0-rc3 I now get an error that says that the M671 array is too long. Is there something I'm overlooking in another setting?

For some reason, I don't have a bed.g file anymore either.

Thanks,

Nate

@OwenD Amazing thanks very much

@OwenD Thanks, that can be run like the M106 command in the macro?

Re: Creating a timed fan Marco and Meta

Hi,

Following on this topic, I've got a similar large format Cartesian printer with a 6HC main board and 3HC expansion boards which I've equipped with a small (M5Stack) dc motor to periodically vibrate for a second to make sure pellets are not binding in the feed passage.

I've got the DC motor connected to the IO_1 of my 3rd 3HC and it runs (constantly, I know this is on 100%, this is just for testing) with this in my config.g -

; Pellet Shaker
M950 P1 C"3.io1.out"  Q450       ; create output/servo 
M42 P1 S1 ; set 100% PWM on GPIO port 1

What I thought I could do is modify the code that @infiniteloop and @OwenD helped @kmoore for his pellet feed-

; filamentmonitor.g
; Check filament progress, feed pellets if needed
if job.file.fileName == null 
    M99 
if {{global.filamentProgress + 11500.0} <= move.extruders[0].position} ;
    set global.filamentProgress =   {move.extruders[0].position + 11500.0} 
    M106 P0 S255 
    G4 S3 
    M106 P0 S0

But in my case, I'd like to switch on a fan connection on the 6HC using the M106 command and pulse the pellets a bit.

Is there a way of adding control over the DC motor connected to the IO_1 pins within that macro?

Thanks very much, Nate

Thanks @droftarts

I'm guessing it's an uncommon setup as you say, in this case it's two expansion boards each with a Y motor and a Z motor and a corresponding endstop.

Ola everyone,

I've got a question about using expansion boards and M574 Axis levelling using endstops.

My machine uses one 6HC main board and three 3HC expansion boards, ideally two Z endstops (lower limit) and two Y endstops attached to two of the three 3HC expansion boards.

; Drives

;Y Lower Left
M569 P1.0 S0                                   ; physical drive 1.0 goes (right Y motor) forwards Y1
;Y Lower Right
M569 P2.1 S1                                  ; physical drive 2.1 goes (left Y motor) forwards Y2
;Y Upper Left
M569 P1.1 S1
;Y Upper Right
M569 P2.0 S0

;Z Left
M569 P1.2 S1                                   ; physical drive 1.2  (right) goes forwards Z1
;Z Right
M569 P2.2 S1                                   ; physical drive 2.2 (left) goes forwards Z1
;M569 P0.4 S0                                   ; physical drive 0.2 goes forwards U

;X
M569 P3.0 S0                                   ; physical drive 3.0 goes forwards X1

Is my Drives code and -

; Endstops
M574 X1 S1 P"!3.io0.in"                         ; configure active-high endstop for low end on X via pin 1.io0.in
M574 Y1 S1 P"!io0.in"                           ; configure active-high endstop for low end on Y via pin io0.in
M574 Z1 S1 P"!1.io0.in"
;M574 Z1 S1 P"!1.io0.in+!2.io0.in"          ; configure active-high endstops for low end on Z via pins zstop and e1stop
;M574 Z1 S1 P"!2.io0.in" 			; configure Z active-high endstop for low end pin 1.io1.in

Is my Endstops code.

At the moment I've got the axis levelling line inactive because I'm unable to get this working and wanted to see if the endstops need to be connected to the main board (or the same expansion?) or do both the drives and the associated endstops need to be connected to the same board (all on one expansion or all on the main board)

Thanks

Nate
