This VFD is massive compared to the LDO one supplied in the kit.

That is an understatement - This thing is massive. Great build!

Thanks! The LDO VFD is half the width of this one. 68mm vers 132mm and depth is 104mm vers 160mm.

When I build the Casa Enclosure these water-cooled components will be transferred into the enclosure electronic bay.

Currently putting the frame together - it is huge! 

Will start printing shortly - still trying to decide on color. Stick to blue, or just go sparkle black.

That thing is a beast!

Install the spindle and start the external wiring. I checked that the spindle #4 pin is ground to the spindle body.

I found out why the LDO VFD is much smaller than the one installed on my mill. The VFD and spindle are 1.5kw (1.5hp) while mine is 2.2kw (2.9hp). @claudermilk A beast she is!

I'm trying to get confirmation that this wiring diagram for the VFD is correct. Post in Discord Millenium and RepRap channels.

Update: this diagram is incorrect see the posting below.

As the LDO kit has a PCB breakout board and I wired according to this

[PFarm]

@mvdveer Thanks for the reference. The LDO expansion module does the same thing as the relay and signal converter except it's an all-in-one module. The Millennium Machine "Assemble Electronic" section shows these two references on connecting the 0-10V converter to the VFD. The VFD in the example is the SL3 series for the 1.5km spindle it's the one LDO supplies with their kit. 

Reference #1

From the Millennium Machine assembly manual:

Reference #2

Since I'm self-sourcing and purchased the 2.2km spindle and VFD these references for the VFD connections don't apply. I'm posting how to wire a Huanyang VFD, 220V 1 Phase input wiring, Spindle wiring and 0-10V signal converter connections since there isn't much info on this.

Note: The photo below shows no spindle ground connection! First, with a multimeter measure for continuity from pin#4 on the spindle and the spindle body. Second, run a ground wire from pin#4 to the ground connection on the VFD. A properly grounded spindle is a very important safety requirement and shouldn't be overlooked!

On the VFD you need to move the J1 jumper to short the 1&2 pin so the speed is controlled from the 0-10V signal converter.

On the 0-10V signal converter module, you need to move the PMW input signal jumper to 24V. position.

Do the pre-flight checks. When doing the spindle check at 24,000 rpm, use a multimeter to measure the output voltage on the signal converter for a 10VDC reading. If it doesn't use adjust the voltage by turning the adjuster screw on the potentiometer.

 

 

A wiring diagram shows the 0-10V signal converter module and enable relay connections to the Huanyang VFD terminals. The enable jumper relay input can be 5V or 12V ensure the voltage selector pin is set to L (5V) as shown in the photo below.

No need to re-program the VFD to use this setup.

Got the beast on its side, changed out the feet, wired the steppers to the Fly 5160 drivers, wired the end stops, wired the enable relay and the analog signal converter, wired the 220V input to the VFD, installed some wago for feeding 36V to the Fly 5160 drivers

[PFarm]

Stepper motors were wired,  VFD control wires were installed,  12V power supply and water cool radiator fans were wired I temporarily wired the Fly 5160 for 24v until I set up the 36V power supply in its separate enclosure.

Nice build. Don't want to know what that weighs as the standard LDO kit is heavy as! 

Like what you're doing here

[PFarm]

@mvdveer Thanks, the good news is I can still lift it to move it around (yes it is heavy as! ). The water pump supplied with the water-cooled spindle is for an open loop setup. The pump is submerged in a bucket with a return line back to the bucket. My setup is a closed-loop and self-contained (attached) to the mill. I haven't seen many water-cooled posts in Discord which makes the build kinda unique for the moment. I need to put it back on its side since I just realized I forgot to wire the tool setter and touch probe.

Which vice did you install on your mill?

Got this one from Amazon. Had to have another mounting hole milled as the two supplied in the mill does not match up with the fixated bed.

[PFarm]

Ran a two-pin Deutsch connector for the tool setter and a three-pin for the touch probe. Removed the 12V to the radiator fan from the 12V power supply and ran PWM 12V wires from the Fly CDY3 motherboard this way I can control the fan speed via temperature.

[PFarm]

Today, I powered the Fly CDY3 board with my variable power supply and explored the RRF interface. Found were to configure the TMC5160.

I also wanted to monitor the spindle water temperature and have the water-cool radiator fans come on at a set temperature from the CNC interface. I got that figured out. The plan is to run and attach a thermistor to the inlet fitting of the radiator

 

The sensor now shows up in the Dashboard

Next is setting up the cycling of the electronic bay fans based on the MCU temperature.

Great build!! I am curious in i purchased the LDO expansion board can i wire it like the LDO manual using a water cooled 2.2 KW spindle as well

Thanks! You can wire the motherboard to the LDO expansion board like in the LDO documentation but you’ll need to figure out the termination in the 2.2kw VFD since it’s a different VFD then the LDO one. I can help you with that.

ok great i didn't even think about that when i purchased this one i just knew i wanted to self source because i can implement upgrades while building it also do you buy chance have any DXF files for the other plates like the  x y and the mounting surface

[PFarm]

Step files for the x/y plate are in the Y stl folder and the Z in the Z folder. Do you already have the spindle and VFD? If so send me the make of the VFD and I'll look for the manual online. FYI SendCut Send cannot fabricate these plates they don't have the right machinery for them I tried. I purchased mine from Fabreeko.

@oggie I'd suggest that you start a build diary for your build this way if someone looking for the same components you're using in your build it will be easier to find.
