I totally agree with Ian!!! I'm waiting for a check so I can upgrade to a 6090 and going the Gecko route.

6090 or 6040? If it's a 6090, congrats, your in for a real treat!

I frikkin love my 6090!

If its a 6040 with a G540, then your still in for a treat (just not as much as with a 6090). I couldn't believe the difference the G540 made to my 6040. I was lucky and had some 48VDC PSU's around so I could get max torque/performance out of the steppers, and it was just fantastic to use then!

cheers, Ian

Hey Ian!

I am in the midst of deciding which 6090 machine to buy and would really appreciate your two cents on which machine you opted on and why! To me it seems that AccTek's 6090 is just a 6040 with a larger table (atleast the price that they sent me was just 100 dollars less for the 6040 than the 6090...), but you're implying that the 6090 is really superior? Have you upgraded the G540 for your 6090 also? Thanks a lot!!

Hi Ville,

The 6090 I think you may be referring to is the benchtop model and is still vastly superior in most ways to a 6040. The one got through Jinan JCut in China however is the 350kg 6090B with Hiwin style linear rails, not round, pretty much the same machine as in the attached pic. Best value thing I've ever bought, just a fantastic machine that's done an absolute crapload of work over the last 5-6 years, and just keeps plugging away as good as the first day I got it. I never did upgrade it to G540 over the Leadshine drivers and NCStudio controller as it has performed pretty much flawless, so I'm not sure if converting to a G540 would actually be an upgrade in this case. For my 6040 I put a G540 on and that was a massive upgrade over the standard rubbish bluebox controller those machines come with.

I'd recommend going for the best you can for the money, at least a 1.5kw spindle, 2kw would be better, linear instead of round rails. etc, etc. Buy once buy well. Take note of the pic of the 6090B how big and thick the gantry sides are, means less flex when machining.

cheers, Ian

@aarggh, this is exactly the kind of information I am seeking also. I'm looking to purchase a 6090 with 1.5 or better spindle. I've seen (and taken notes from) several of your posts here on cnczone, and would really appreciate if you have any advice on where to buy.

Do you recommend Jinan Jcut as a seller? You mention that your 6090B came with a leadshine controller - I've read some very positive remarks about those as well. I'm surprised to hear that this machine comes equipped with one stock! Do you recommend anyone in particular to contact?

Here's a link to another post I made with some info on what I'm looking for: http://www.cnczone.com/forums/chines...cnc-posts.html

Any advice you can lend would be GREATLY appreciated as you seem to have been around the block with this stuff!

Hi Danny,

I'm still pretty stoked with my machine and couldn't be happier at all.

Paying the extra for the big frame version and the quality linear rails was more than worth the extra cost.

I just finished a sizable 3D picture frame the other day done with a 1.5mm ball nose that ran for many hours, and not a beat missed even with the really muggy 35+ degree days we've been having in Melb! Since I solved the rare overheating-stepper issue the machine is just flawless to run now.

I dealt with Sanny at Jinan Jcut, email address at the time was [email protected], but this was some years back so no doubt staff have changed.

Whoever you end up going with, as I say to everyone considering buying a machine from China, take everything you hear with a grain of salt as there's many people who make it a pastime to just bash anything Chinese without any experience on the matter, and there are VERY different cultural and business perspectives that can make the affair quite painful, or one that works out good in the end.

The trick is to keep the pressure on them that you want very frequent updates on YOUR specific machine, not just of a general one in works, pictures of the build progress of YOUR machine, videos of YOUR machine being tested, etc, etc, throughout the period, which you can probably expect to take twice as long as the best estimates they provide. Ask question on anything that doesn't look good to you so far, they are quite pragmatic and will be keen to do whatever they need to ensure the final payment is made after the build is complete.

Take the offered delivery to your door as them being overly optimistic about how shipping works in most countries, and be prepared to have a shipping broker ready in case at the last hour you have to rush through paperwork and clearances to get it from the ship to port, and then cleared for the trucking company. These last steps cost me a lot of money and lack of sleep at the time, but even so the machine still worked out around 25% of the same machine through a local supplier.

Lastly, don't be tempted to buy the crap rotary axis they offer, it really is garbage and a complete waste of money, it has just enough torque to engrave an apple, not very useful at all.

cheers, Ian
