How about all the missing bolts in the rails on all the machines in the range

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)

Hi JAZZCNC
I have been lookig at the same CNC router on Ebay and wondering about the quality of it, so your response to this question was very useful for me
I note you say that you build machines for people..
I am interested to get an idea from you as to what you would charge for a similar sized machine, (say 1000 x 1000 or 1220 x 1220 ie half sheet) that would be sturdy enough and suitable for milling aluminium.
Many thanks

The machine on ebay cuts aluminium fine, all day long, despite being designed for cutting MDF. Nice clean cuts even in thin 1050 sheet.
In comparison to others in similar price bracket, i.e. 60/90 chinese routers, Xcarve and so on, it's far better.
Could the machines be better, yes, could the finish be better, yes but for around £2500k after some basic mods they work well.

Hi Chip Owner
Thanks for the feedback
What are the basic mods you are referring to ?
Is that the machine you are using ?
You are referring to thin 1050 sheet. Would it be OK to mill say 25mm aluminium parts ? (understandly with the appropriate depth of cut, plunge depth per pass and feed speeds)?
When you say ... the machine could be better, what parts are you referring to.
Many thanks

Yes I have one of those machines, ordered just before lock down, I would have liked to visit during the build process but this wasn't an option. Things like all the screw in the rails as mentioned elsewhere, I had to finish drill & tap some of these. Also the cables weren't through the frame tube.
Position of VFD is personal choice.
I've added a galvanized plate across both sides of the bed side to reduce side spill of chips, I've added a similar plate to the rear of the gantry, I'll be adding a 4th to the very rear soon too. I've also added some triangle braces on the Z axis top plate, long term I'll do these properly.
Part way through a vac bed installation as I cut thin sheet and will eventually replace the supplied MDF wasteboard/baseboard with steel.
25mm aluminium parts would be fine, it's all down to bit you use and hold down method.
It doesn't do slow at speeds 300-1100mm per minute it's very noisy. Over 1150mm per minute it's fine. Our current bits allow cutting of 1050 sheet at 1150mm-1300mm - with a nice clean cut requiring minimal cleanup. We're changing to a slightly higher grade on next tool order to increase cutting speeds further.
