There's an impressive cost escalator on size... and I honestly can't see how its justified. Each sized machine is essentially just a bit more box-section/rail/screw and not much else.

Anyway, what is curious to me is the choice to orientate the gantry to straddle the widest axis... Is that a good thing? (it feels like you're creating a problem with an unsupportable beam... if deflection was a concern)

Na the beams are full of helium to stop them from sagging

I thought that by missing out alternate bolts on the rails, it would create triangular compression forces along the beam and hence the mechanical stiffness would be greatly enhanced.

Such a pity we are well past April 1

The helium is dual purpose.!! . . . It's so you can still laugh when you really want to cry because realize what a bog of shite you bought....

Well Jazz. I wouldn't buy it for aluminium stock.
By the time you get the spindle moving in it you'll be running at roughly 0.1kw to 0.25kw (110w - 250w) with barely any torque.
A Seig X2 mill is 350w and that can just about do 1mm DOC with a 6mm cutter at a conservative feed.

Before you get too enthusiastic about this machine, did you inquire with the seller as to whether or not it meets the requirements laid out in the Low Voltage Directive? Every low voltage (sub 1kV) device sold in the country needs to comply with this. It's the testing regime that most v.small manufacturers fall down on as the requisite test equipment costs are very high, or the costs of having a 3rd party carry out the required tests are prohibitive.

The only way around it legally if it doesn't meet the LVD requirements is if it is sold in kit form, but the listing seems to suggest that it is built to order?

If the guy/gal is selling home made electrical equipment, and I'm mostly referring to the control system, without meeting his statutory legal requirements, then it's only a matter of time before this catches up with him/her, Here's a quote that you can verify the veracity of quite easily...

“It is an offence to supply electrical equipment which does not comply with the requirements of the Regulations. Any person committing an offence is liable,
under summary conviction to imprisonment, a fine or both”

Cheers

I would suggest your interpretation of LVD might be wrong. For kick offs most of the equipment used will be below the voltage thresholds so not covered, and the components that are, the PC, power supplies and the VFD and spindle will have their own individual compliance. The overall machine is effectively a "one off" system comprising of existing certified equipment, assemblied to order, in the same way thousands of "one off" control panels are built outside of LVD.

Firstly, the machine takes a 230v feed so it well and truly falls within the LVD's thresholds.

Secondly, all control panels are either built to LVD or to the Machine Directive, depending on what it is exactly they control and the MD incorporates all of the elements of the LVD anyway.

Finally, most control panels are built using existing parts that are separately certified, but that doesn't mean they aren't subject to certification when assembled and wired together, otherwise how could you have any confidence that it had been built safely?

That's your interpretation, mine is different.

It will all change on 1/1/21 anyway.

Hi all
Stumbled onto this thread and wanted to join to share first Hand my experiences.

So I run a Axyz router for my day job my boss lets me run my own bits now and then bit wanted one at my home workshop.
I had intended to go for the entry level Ali frame desktop machine but saw these and thought the looked up to scratch.

Well when the machine arrived seemed okay plugged in and had a play.

I do have quite a lot to pick at so please bear with me. I've built and desined many machines so had a idea what to look for

1st I asked for a base the machine was the desktop version just tacked to a floor base with no feet.
The gantry lead screw supports where loose and the screw was binding on the gantry end plate.

The frame is 3mm side to side out of square front to back 2mm corner to corner

Missing bolts on the guide rails

Over 50% of the bolts loose or not torqued

On the 3mm thick gantry bearing plates which have two m6 bolts one bolt was just held in to a stripped hole with locktite

Gantry is twisted

Whole machine has such a high enter of gravity it rocks (if the gantry was rotated 90degrees to span the shorted distance may fix part of this

Ridiculous amount of vibration / resonation

Drilled plates and hole allingment poorly done and on limits with bolts binding.

Over all I should of built my own but would of took way too long.
Pretty disappointed with my purchase but
I will make do and let the machine earn it's money back and I will re invest in a better

Welcome to the forum Chris. Thanks for the report not many own up to the fact that they have bought a load of crap.

It looks like you are going to be a valuable member of the forum with the knowledge you have.
