@alankilian
Thank you very much clearing it out., I'm going to go around this VFD and manual again with more deep research! And I will definitely update you guys about the progress. I've built many 3D Printers , few of them pretty big.. But now I've got a bigger challenge with A LOT of more power and torque =))
For the begining I want to make this thing work as is..
But why I actually brought this machine to my place., because I believe that with flexibility of macros in Duet and ways to easy attach more motors and sensors etc I can explore some new ways to create with this machine.
The plan is to extend the height of the bridge of X axis to about 1.5m (from 30cm) ,
to replace the spindle on much lighter one and to add pellet extruder.
I'm sure it's achievable task ! And it's definitely super cool project to do !
I already made one little cnc machine (1x1m) on Duet base , but the spindle there was much simpler Chinese 1000w version , which uses just potentiometer to adjust the speed.
So I going dig , read , and sleep with it for a few more days , to realise that I'm not going to make mistake with it..
@jens55 was 100% right about one thing.. it's a three phase, and 1000 times more power than any 3D printer))
Hope to back with some good news soon! Thanx @alankilian @theKM and @jens55 ! This is great, I'm already not alone in this project!

@t3p3tony You are the King Man!
@JoergS5 @o_lampe Thanks for your help friends !!
I'm almost gave up on this board! Nothing was helping..
It's looks like it some weird bug with previous version of a firmware ., which was fixed by update to 3.4b5!
I'm feel in family now !

@jay_s_uk
Yeah, a messed up with heater , by giving a many trying attempts to see any different after all combinations with drivers %) Now I realised that made some mess. .

I'll back to the first configuration ,I guess the heaters aren't a problem .
And thanks allot for quick replay , I have a feeling it will solve it.. D8 is stone of all the problems)) !
Hope I'll be back soon with the working config!
Thanks a lot Jay!

Hey Folks !
Is there anyone here can help to make things clearer..?
Following the steps of @Max3D He made a post with with some explanations : Huanyang VFD 2,2kw Water Cooled Spindle to D3MB6HCv1 mainboard.
Letting to control the RPM by one module connected to the OUT_1 port .

I did the steps with PD001, PD002 ,PD070 and checked it with my VFD Manual.

Now when I turning ON the machine after installing of the red wire jumper the spindle starts rotating without any commands.
It's doesn't stop by M5 and looks , like doesn't want rotate slower than ~500rpm. I'm able to stop it only from the VFD interface .

Do I need to connect the second module to another port to control On/Off function?

May be I've missed something... Clear wiring diagram could be also helpful.

@max3d said in Huanyang VFD 2,2kw Water Cooled Spindle to D3MB6HCv1 mainboard:

To test the setup, enter M3 S500 on the DWC console to turn the spindle @ 500 RPM and all should be well. Enter M5 to turn it off.

But after installing the red wire jumper the spindle starts rotating after its powered and doesn't stop by M5 and looks , like doesn't want rotate slower than ~500rpm
Do I need to connect the second module to another port to control On/Off function?

The Mixed 2motor extruder for clay are working! Cheers!

BTW. if I use command M542 ; Enable Laser mode - it switching the DWC to CNC mode and there are no tools are showed at all.. But I'll back to it later !

@jay_s_uk Thanks again! it's alive!

The Mixed 2motor extruder for clay are working! Cheers!

@jay_s_uk
Yeah, a messed up with heater , by giving a many trying attempts to see any different after all combinations with drivers %) Now I realised that made some mess. .

I'll back to the first configuration ,I guess the heaters aren't a problem .
And thanks allot for quick replay , I have a feeling it will solve it.. D8 is stone of all the problems)) !
Hope I'll be back soon with the working config!
Thanks a lot Jay!

Trying to attach the clay extruder with dual motors but cant see it!
Dear folks ! Anyone can see the problem?

I'm using Duet Expansion Breakout Board And External Drivers.
Sometime before I have already successfully used this setup with dual motors mixed extrusion. But new Resetup and version of the firmware making confuse.

I'll appreciate any help! Have tried so many combinations already , but no solution yet . .

@dc42 Here is all what I've got about the laser ..
Laser Aliexpress link.....

@dc42 Thank you for quick replay !
I guess I wasn't clear enough about my hardware setup:

I'm using this port on Duet Expansion Breakout Board
And after I used M452 C"duex.pwm5" F250 command in my Config.g the laser is acting the same. Full power from the start and the fans on it are always on from the V+ and ground form my power supply , even I'm unplugging the PWM from the board.
So I think I'll need to power it from the third free Fan port on my Duet WiFi to avoid the spinning the Laser fans while it's not in work.

I've heard very good feedbacks about this laser module and eventually decided to give it a try .
AliExpress 80w LAser

In Duet wiki is saying -
Note: if your system includes either a DueX expansion board or an expansion Breakout Board, then that board already includes this circuitry.

So I'm attaching the +12v and ground of the laser to Duet 12v power supply
And PWM to PWM7 on Expansion board .
When the machine is Laser Mode (m452)

• the laser is ON from the start. if I unplug the PWM - it's doesn't work.
  If the ground cable is also connected to Expansion PWM7 ground - nothing happening...

@tenaja
Thank you!
I did few jobs already with the spindle working passively from the previous controller, all the rest did Duet. And I didn't have backlash problems.
Now I've replaced the spindle on the 3.5kw Chinese watercooled one.
And still have some setup to finish to control it from DWC.
The old 7kw spindle will wait for some more robust machine.
Thanks for answering!!
