Hi Chris,

Like Clive says thanks for the honest feedback. As a machine builder my self I'm in a very delicate position when I point out the faults and weaknesses on these machines and I've had some heated debates with some of the fanboys who won't own up or don't know the difference between a real machine and a pile of metal turned to scrap, so it's nice to hear from actual victims. Yes, I said Victims because IMO it verges on criminal and you are not alone.

This isn't going to be much consolation to you but only in the last few weeks, I've been helping another victim of these machines who bought an 8x4 that was pretty much dumped in his workshop and left to defend for himself with no help or support, the guy won't answer emails or phone.
The machine wasn't set up in any way shape or form and the user didn't have a clue how to set it up, why would he, when he thought he was buying a ready to use the machine, not a DIY kit with no support.
There are no limit switches or home switch fitted and very little in the way of safety. The spindle is completely unsafe and illegal in that it starts up on its own if the VFD is turned on before the PC so there is no Charge pump or safety interlocks on it.
The flimsy gantry is a joke and at over 8ft wide, it's got the strength of a piece of spaghetti, so much so that when delivered the spindle was located in the center and dropped to touch the bed to stop it bouncing in transport, which made me chuckle because that says it all to me.!

I got him working over the phone so I haven't seen the actual machine but I can imagine the state of it will be very similar to yours. Like you, he's going to make the best of it and it will certainly provide a challenging learning machine which I hope doesn't put him off because it's certainly going to be a frustrating machine.

WARNING BLATANT SELF PROMOTION BELOW.!
Now regards the Wide and narrow format this isn't a problem if the machine is built correctly and it's actually a good space saver which suits the "men in shed " environments were space and layout is at a premium.

So here comes the self-promotion.!! . .. I wasn't going to do this just yet but why not as others will no doubt be watching this and it may just save them buying rubbish.!

I'm currently building several (8) machines in two sizes, 1250x600 and 900x600 that I'm going to offer for sale to meet the needs of people on a lower budget that uses the same wide/narrow format but obviously done correctly and with much better components, like profiled linear rails, etc.

Fully welded steel frames using 100mm and 80mm 5mm wall tubes with 5mm and 10mm steel plates in various places. The Gantry will be using my proven "L" shape design using HD profiles directly sat on the linear rails with 10mm steel gantry ends for connecting to the ball screws which will be located inside the top tubes to protect and keep the width down to a minimum.
The Z-axis will be a new design (for me anyway), which is still fully covered like what I fit on all my machines and using a 20mm Cast tooling plate but with pocketed 10mm side plates which bolt into the rear plate and make a much stronger z-axis.

The Motors will be Lichuan 5.5Nm and 4.5Nm Closed loop with AC drives directly driving the ball-screws.

I going to offer several options ranging from a fully built working mechanical frame with motors but no electrics or spindle etc for those that have the knowledge to tackle the electrical side. Then going up in electrical spec. In Total there will be 5 options starting at just over £2k up to £4k for the fully loaded floor-mounted Ethernet version with Spindle PC etc.

All the machines are Bench mounted with an optional Stand to make it free-standing.
Here's a sneak preview.! If anyone is interested get in touch via PM.
