CNC router build

Did a bit of milling in acrylic to test the part sizes.....had my clamp meter connected to record the max current drawn. Must say that i was very surprised how little current the machine consumed.

The spindle was running at 14000 RPM...

I have the same Fluke meter! What I was wondering and I need to look it up, if it reads the spindle power leads correctly at anything other than 50/60 Hz?

Looks like it will AC Amps

Range 0 - 999.9 A
Accuracy 2% ± 5 counts (10-100 Hz), 6% ± 5 counts (100 - 400 Hz)
Crest Factor(50/60 Hz) 3 @ 500A, 2.5 @ 600A, 1.42@1000 A, add 2% for CF>2
AC Response True-rms

I measured from the temporary main supply....so it measured the total current consumed by the entire machine. It's a true rms meter so it should be accurate.
Of course the spindle would draw more when loaded , but its still much less than i expected. I was running temporarily from a 10 A outlet

Milled the first few holes in the t-slot base. It seems to handle the aluminium milling okay. Managed to get some brush and acrylic for the dust shoe. Meantime the 6040 is getting a service, some bearings will be replaced before the new owner pic it up. This little machine really performed very well!! Maybe this would be a good size machine to start with making

Bed milled and secured. It helps a lot when everything is nice and square

Exciting add the spoil board and ready for work

Erics, do you remember where you got the drag chains from?

They look nice. The ones I have are really bad.

Yes it is exciting True, spoil board and dust extraction....then i can finish making all the bits and pieces. The 6040 is sold but when i gave it a service i found a few issues. Getting a complete overhaul

Thank you ericks.

Decided to modify the spindle connection. Busy with the dust shoe design....

That's better than the plastic gland you had, at least you can ground the shield with that plug

I did have the shield grounded with the pvc gland. Reason i changed it is for quick removal

Today i milled a couple of pieces to check the accuracy. Must say i am very happy with the results. The mill finish is great and even though i have not completed the setup and calibration everything is close to size and square.

Good to see your progress Ericks.

A few things i am looking at changing. I was running the machine from my laptop....plan to rather use my desktop, only issue is it is Windows 7/32 bit so i need to install the 64 bit W7.
Also i will still stop and start the spindle through uccnc but i might take over the speed ref....it's just personal choice. Ordered a wireless pendant, will see how it goes

[ericks]

sorry.....i have cleared my inbox a little

If you have a UC300ETH, just add a pot for spindle override, and you have the best of both worlds. Just turn the knob to change the speed.
