I sounds like motors not correctly wired to the board. Make sure that the coils are correctly paired...

@gloomyandy yeah, got you! As I already checked, by setting the tolerance to 0.004 it did already the trick.

thanks a lot!

Well, I did change the trigger height to 16.25 and re-run the delta calibration. The Delta Height changed by 0.2mm (or so). I approached the nozzle to the bed until Z=0 and, sure enough, I got nice paper grab...

Thanks a lot, everybody

Yesterday I noticed something weird while using the pendant. The multiplier knob was set at x10 and, not thinking about it, I tried to move the Z axis. Because I turned the wheel too much, I got a message on the display telling me to chill out (paraphrasing here) because I wanted to move more than the axis allows. So far, so good. However the X axis moved a little bit instead, even though the Z axis was selected on the axis knob. Now that's weird. Once I switched to x0.1 multiplier, the Z axis moved ok.
Knowing that, I'll be more careful from now on, but I am really curious if this is a "global" bug or it is just me.

I am using an Arduino Nano and I changed the resistor on it in order for the bypass of the display to work. The Arduino Pro Micro I ordered came when the Pendant was already assembled, so I saw no reason to open it up again. Also, I did not update the firmware to the latest version, as I understood it was only Pro Micro related and I didn't see a point on doing it.

Cheers!

Well, I finally got the time to do some experimenting. If I understood that correctly, I was mistaken regarding the G10 command. It seems it's like this:

P1 is G54 (WCS #1)
P2 is G55 (WCS #2)
etc.

The closest thing I‘ve seen similar to what would be using Stall detection as a Z probe is the Smart Effector on a Delta. It is not the same, as it is based in some other phenomenon, but you effectively use the nozzle tip a sensor. Maybe one could design a carriage for a cartesian printer this this technology??

BTW, buying the Smart Effector for my Delta was one of the best decisions I‘ve done (3D Printing related, that is).

aren't you missing something?. The error tells you exactly what is happening. Instead of looking to your config files, check the continuity of you motor cables. I got this error once and it pop up because one of the motor cables was pinch by the printer's frame and eventually was severed. I repaired the cable and everything was fine.

Well, i mixed the code on the 3 independent homing files into one homeall.g file (see below). It appears to work without any issues...

I hope this post helps somebody else with similar issues.

Thanks a lot, everyone.

So, as promised the following is what I've done to get my SuperPID working flawlessly with my Duet Wifi 2.

The wiring schematic is as follows (please don't mind the inaccuracy of standard symbols):

The ON/OFF is accomplished using the FAN0 (-) pin to ground the RUN port on the SuperPID.
The router RPM of the router is controlled by the (-) pin of the FAN1.

On the config.g file on the Duet a file named customconfig.g is called in which customizations are done without modifying the main config.g file. On this file I added the following lines, which configure the FAN1 as the "Tool 0" pin and set the RPM for a max PWM signal (255). It also inverts the PWM signal, so that the more PWM the more RPM:

M106 P1 I-1 H-1 A21 ; disable FAN2 & allocate Tool 0 to pin 21
M563 P0 S"Spindle" ;
M453 S"Spindle" P21 I1 T0 R30000; , Tool 0 = Spindle, invert PWM, 30000 RPM at max PWM

To turn ON the router:

M106 P0 S255

To turn OFF the router:

M107 P0

To set the RPMs:

M3 S15000  ; Set the router speed at 15000 RPM (PWM aprox 128)

@JoergS5 thanks, T0 is at the very end of the config.g file, not shown on the snippet above.

@jay_s_uk that seems to have been the issue, apparently. I added the example line shown on the wiki and it appears to work ok:

M584 X0 Y1 Z2:3 E4:5:6

I wonder why did it work without that line previously...

So, the printer has undergone several Y-homings since I changed the speed and has suffered 0 fails, so I would say the issue is solved. Thanks again!

I modified my Duet-powered Ooznest Workbee last year with a SuperPID, with which I can control a modified a router (DeWalt in my case). You can see some infor here:

https://forum.duet3d.com/topic/17002/superpid-spindle-controller-with-duet-wifi-v2-x/18?_=1638613062447

After many liters of coffee and documentation reading, I was able to modify the Post-processor that the folks back on Ooznest provide for their Workbee machines. With it I am able to turn on and off the spindle via GCode as well as control the RPM.

It is not perfect, since my understanding of how post-processors are coded is extremely limited, but maybe it could be a good starting point. I am happy to share it with whomever needs it:

WorkBee - Duet_with_router_control.cps

Have fun!

@phaedrux ... I guess I should start reading the release notes from now on... thanks!

@phaedrux well... I promised I would report back...

Thanks a lot! At the end of the day it was just the simple "level it the old fashioned way before..."

Can't thank you enough, it was bothering me for a while...

Hi all,

yesterday I updated the firmware of my Ooznest Workbee. Last year I upgraded her with a SuperPID and a Laser. It took a while, but I was able to create some simple macros for switching between CNC and Laser modes.

However now the firmware runs FFR3 and these macros do not work anymore and I am having a hard time adapting them, so I would appreciate some help here.

Before the upgrade this was my setting:

customconfig.g (which is called at the end on config.g)

; ADD ANY CUSTOM SETTINGS BELOW

;New Steps=(mm requested*current steps)/mm actual



M92  X399.03 Y398.49 Z400 ; Set steps per mm

M574 X2 Y2 Z2 S1 ; Set active low endstops

M106 P1 I-1 H-1 A21 ; disable FAN2 & allocate tool 0 to pin 21
M563 P0 S"Spindle" ;
M453 S"Spindle" P21 I1 T0 R30000; , Tool 0 = Spindle, invert PWM, 30000 RPM at max PWM

Switch to Laser.g (macro to switch from CNC to Laser modes)

M106 P2 S255  ; turn on 12v PSU

M307 H3 A-1 C-1 D-1       ; Disable Heater output on H3
M452 P3 S1 R255 F200         ; Enable Laser mode, on output 3 (heater 3), with max intensity being 255, and a PWM frequency of 200

Switch to CNC.g (macro to switch from Laser to CNC modes)

M106 P2 S0  ; turn off 12v PSU

M453 ; Put the machine into CNC Modes

M140 H-1 ; Disable heated bed
M208 X800 Y770 Z94 S0 ; Set axis maxima
M98 Pcustomconfig.g ; Execute custom config settings

As far as I remember I used the output on FAN1 to control the Spindle speed.
The FAN2 was used to control a SSR to turn on/off a 12v PSU, for the laser.

the new config.g provided by Ooznest, simply calls different config files:

config.g (by Ooznest)

; Configuration file for Duet
; executed by the firmware on start-up
; WorkBee Firmware Version 1.1

global systemSettingsVersion={1.2}

; User Configuration files

M501 ; Load Stored Parameters 

The instructions provided by the folks at Ooznest seem a little bit superficial, in my opinion:

https://learn.ooznest.co.uk/Guide/How+To+Update+WorkBee+Firmware+V1.0.7+>+V3.3.0-1.2/240#s1128

I asked for help on their site, but they came back to me twice providing solutions for something I was not having an issue with...

So I would appreciate any help somebody would give me in adapting my old macros to the new paradigm...

Thanks in advance!

@Phaedrux thanks a lot for your help. Actually shortly after I posted the question I found where the problem was. The command disabling the heated bed was being called twice. I cleaned it up and now everything seems to be working just fine. Thanks a lot again!

well, I just made a short test in which I unplugged the Pendant and plugged the PanelDue as usual. The Macro in this configuration works just fine. So, apparently, it is a problem with the Pendant. I will post the problem over the Pendant post.

If somebody lands on this thread looking for the same info as I was, here you have it. This is what did it after some headaches:

well, just as usual after I posted something I myself come up with an improvement...

I changed the macros as follows:

Laser focus ON

M106 P2 S255  ; turn on laser's 12v PSU

 
M453   ; Enable CNC Mode

M950 P0 C"!exp.heater3" Q1000   ; assign laser pin to a pin number

M42 P0 S0.01  ; set 1% PWM on GPIO port 0


; do the focusing stuff

Laser Focus OFF

M42 P0 S0 ; disable laser

M950 P0 C"nil" ; free heater3 again for use in laser mode

M106 P2 S0  ; turn on laser's 12v PSU

And I changed my "switch to CNC macro to:

M5 
M106 P2 S0  ; turn off 12v PSU
M452 C"nil" ; free "exp.heater3" pin
M453 ; Put the machine into CNC Mode

M550 P"WorkBee CNC Machine" ; Set machine name

in which I added the M452 C"nil" line.

This seems to work, although when I go back to CNC mode the console throws a red warning:

Error: DueX fan or GPIO pins may not be used to control lasers

but well, it looks like I will have to live with it. On a positive side, I think that the M42 command lets me control the power of the laser somehow better. Yesterday I used it "the old way" with a Fan port and even a M106 P3 S0.001 would start burning the plywood after a couple of seconds.

well, if anyone is following this thread, I just want to mention that it has been solved.

The issue was the name of the macro together with the firmware version of the Paneldue. I changed the name of the macro to be just text and it worked fine. And just for the sake of it, I updated the firmware to the latest version. Everything works just fine now.
