Ticking along, torsion box bench and frame built. Waiting for castors and going to buy 40mm sq profile aluminium legs for bench as the last ones were wood and I was never 100% on them.

An update on progress.
bench and legs roughed in. Feet and braces coming, still to do magnetic latch to hold them up.
frame of cnc and wasteboard mounted, I have a detail photo of that uploaded here.
took a photo of one side plate and my start tidying cables, many more hours of that left to go.
the last photo is a close up of the bench in folded position, I suspect it is too low for spindle and will need moving slightly, I have about 25 mm clearance to move wasteboard up so I anticipate no real issue. Plan to check next session and fix now.

That is neat !! Exactly what I would need to do as I have limited space. How deep is it when folded in?

motor wiring done and connected to controller.
testing this weekend for movement and basic configuration, time to brush upon g code commands and pray I don’t stuff a limit switch.
router cable is too short, I changed the way I wanted to lay it and needed a couple more meters. New cable on order, my fault.
Ben from xyz carve sent through replacement parts for the few missing bits (2 bolts for spindle clamp) and the damaged bearing. best to call him as the messaging system on his website and email seems to be a bit patchy. He answers regularly and is very responsive. All other bits were present and I even have a few spares here and there.
leg braces arrived and will be installed over w/e as well.
once movement is confirmed and machine operational it will be time to install spindle into carriage and attach shelf so I can place a laptop. Dust collection will come later

I have movement.
Compared to the last build I did the setup and configuration was a breeze. Had the unit up and going in about 20 minutes, including installing the drivers.
UGS has come a long way in the last 2 years since I ran my old one, even has a setup wizard that sorts just about everything out.
New cable installed for spindle.
Next steps are to install fold out bench, connect the spindle and wire everything in permanently.

Looking good.
I’m thinking of starting a thread to see what those who have CNCs use them for as I’m on the fence re buying one.

Shop vac, no room for bigger and the last one was usable with no extraction.
trick there was to avoid mdf and set up the cutter feed and speed to make heavier chips and not sawdust.
however it did require regular visits with the vacuum cleaner to move the bulk of the material away when roughing.

Success,
Due to the poor weather I escaped garden duty to spend time with my other wife. The poor dear was feeling neglected the last couple of weeks.
Shelving installed, wiring completed, leg hinges replaced and functional (still need work or better hinges).
Spindle VFD configured, wired in and tested.
Photo below shows system almost as it will be in use. Have a fold out bench to put laptop on but waiting on hinges.

Dust shoe, I bought this with the machine. I liked the attachment method and magnets, not so sure about its size and that the brush length was short so it didn't cover the rear of the spindle, also a lot of space around the top.
Seems like it will need some hefty vacuum to run this properly and I don't have that sort of machine (yet).

Instrumentation installed for VFD speed control and probe in control box. This isn't normally part of the basic kit but the control board has the capability to both probe and control the VFD directly. Different style plugs to prevent oops moments.

Commissioning VFD and spindle took a bit of time. My daughter was helping and didn't plug in the cable properly so that cost me about 45 min checking parameters and wiring. But works quite well now. I can set spindle speed, start and stop and change speed on the fly.
Noise is substantially less than the router, looking forward to cutting stuff.
Next steps are to get a short 100mm rod turned down to fit in spindle chuck and tram it with the fancy dial gauge I bought.
Surface waste board.
Set up vacuum system
Order more bits, lots more bits.
Install fold out desk.
Make the hundred things the family lined up for me before I can do what I want to.

I have function and cutting ability.
needed to tram still, waiting on metal rod and need to get it turned down. It’s out a fair bit, but I couldn’t wait.
Home made z probe working ok. Have better coming.
test pattern attached

I post my videos to YouTube. What’s “need to tram still”?
Cheers

Tramming is what machinists call aligning the spindle perpendicular to the spoil board.
If not perfectly square the cutter is deeper on one side compared to the other and leaves lines in the work.
Mine is not yet set up to make sure its square and cutting today showed me I need to adjust relative to the Y axis.
Not yet tested X axis but I expect similar.
If the pics are good enough you can see lines in the test piece.
There is another process where I need to ensure the spoil board is level compared to the spindle everywhere. Achieved by cutting into the spoil board 0.25mm or so. So long as you cut everywhere it will work.
All normal adjustments for a new machine and whenever calibration is required.
Results of test piece measurements.
My circles are distinctly oval shaped when pocketing and measuring from the bottom
Y axis about 5% out, X axis closer to 10%.
When measuring from the top its more like 5% and 2% or 0.7 and 0.2mm out on a 14mm diameter circle.
Square that should be 50mm is 49.6 on the Y and 49.2 on the X.
However circle cut on inside of the line has the measurements fairly ok.
60mm diameter circle was 60.25 on the X and 60.25 on the Y. That's about 1% error or about what I expected. 0.3mm is a common accuracy for these machines when belt driven. I expect I can achieve 0.1mm if I try.
Z heights are all within 0.2mm, hard to measure because of the uneven surface.
Synopsis.
Machine configuration is probably correct out of the box, spindle really needs to be squared up and trammed.
Z axis is within the accuracy of my cheap calipers. X+Y will likely be close with some slight tweaks.
Just need to get a steel rod turned down to fit in the spindle. Another day perhaps.

More toys arrived.
bought from maker store.
3CA90BC1-B782-4A86-BF2B-01F2FC519AB6.jpg
A fancy probe that does x y and z. Allows me to locate corners easily.
one 1/4 in e11 collett as the one supplied was 6mm which is tight on the 1/4 in stuff.
two 1/8 in end mills, one up cut and one downcut. I wanted the Sutton ones but these were available and I need to find the local Sutton supplier.
