DownUnder Machine Build .. Pro 60120 with Servos and other fun stuff

[andrewwong2000]

So I think I first spoke to Cory from CNCRP back in 2016.
After much R&D, saving and thought.. and countless hours reading..

I think my order will ship from CNCRP this week, and take a few weeks to get to Perth via sea freight.
In the meantime, there has been much planning & sourcing of the controls and electronics - I decided to
go all in.

Leave the photos to give you an idea of what's on the plan...

i. Spindle - went for the 3.5kW ER25 sized Chinese eBay spindle.. the spindle/collet runout was < 0.008mm . Deflection of the gantry/tool will be key.
ii. 3 phase VFD, braking resistor, line reactor in separate steel enclosure
iii. Main enclosure with expansion for 4th axis, ETH300/UB1 plus an ethernet PLC for delayed start/control stations/state machine/email alerts

Currently waiting for slotted ducting and final batch of electrical cable / parts to finish the panels then it should look a lot better!

Looking good.....all the best with your build

[OlfCNC]

Looks like a serious setup.

Some progress

I see you have a different VFD now....what happened?

[andrewwong2000]

No dramas.. the white one is an old 1ph Powtran PI8100 I had which was used as a mockup. The black one is the new 3ph PI9130 I bought.

Nice

I see you have a load or line reactor? Nice setup.

[andrewwong2000]

It seems I need line reactors for my local power supply for a stable running VFD.

I had chronic problems running the 1 to 3 phase Powtran on my dust cyclone for ages, where it would trip out every few minutes.

I then tried a more expensive 3 ph Lenze VFD with an EMI filter .. but that also kept tripping out as well.

A 3% line reactor did wonders for the reliability of that system and at a far cheaper cost (US$120) than renting a 3 phase power analyzer to track down if it was a transient, phase imbalance or other supply issue.

Another benefit was the slight drop in voltage as my supply last time I checked was 240/415v

Have you received the Pro60120?

[andrewwong2000]

Not yet.. CNCRP quoted 5 weeks but that is the actual ship travel time ..

As it is LCL , it will be a total time of 2.5 weeks before the ship even leaves port.

So in reality from leaving CNCRP mid August to my door will be mid October

Exciting!! i have looked at their machines.....really impressive

[andrewwong2000]

I’ll be really excited if it actually can mill some 6061 but I am fully aware it’s not a VMC ..

If it can mill Jarrah and HDPE/Delrin I’ll be happy enough

I guess that's why i decided not to buy one of their machines. I needed something very rigid to also do aluminium....hopefully my build will be a success

[andrewwong2000]

Three machines needed 4axis wood router, metal mill and metal lathe.

That's sounds good.....my next build will be a cnc mill....however i don't plan to mill metal, i don't mind aluminium chips but really don't like metal chips

[andrewwong2000]

More progress

Great job!!

[andrewwong2000]

Had a bit of time today to get into the wiring.. this is going to take a few more weekends !

The 24V systems power up and the interposing relays and contactors are working nicely.

You can see the space left for the 5th Servo drive / Contactor / Relay .. if/when I go 4 Axis.

Can you explain the purpose of that Crouzet device?
