That welding video was brilliant! Very good!
Aside from the serious trouble you'll have with the machine flexing in every direction in use, relying on a dust enclosure will simply clog up every single part of the machine that moves with dust,...
I wouldn't be overly concerned about the stepper choices to select from, so long as you aim for as low an inductance as possible, and around 270-300oz/in at a minimum, anything in that range or a bit...
All of them are great, but this one is just exceptionally great!
Inkscape lets you do this reasonably easy once you're a bit familiar with the program, and play around with the "Path" and "Object to Path" options. I tried to open the file but was unable to.
I'd...
Personally I'm not a fan of the CNC Sharks as they are the most over priced and over hyped machines around, but this one seems to be around 1/5 of the normal cost which at least makes it more...
Depends how serious you are and what tools you have available Steve.
Without a mill you'd need to pay someone to machine the RHS flat on preferably all 4 sides, and you'd need to be sure they...
Given the variance of VFD's used for these machines, it would be an idea to post the model of the VFD with your machine.
cheers, Ian
Here in OZ that's most definitely not the standard!
Now that we have gov subsidised slave labour with the "Internship Program" the situations only gotten much, much worse.
Most employers are...
Hi Bivegele, I never got around to rewiring the machine as it has been amazingly reliable.
The issues I had with the machine starting up in a funny state I now suspect were possibly due to mains...
I see not much has changed on the zone since I last bothered to log on!
Awesome looking machine, nice design and decent price too, I reckon the buyer will be very happy.
I love it! Brilliant job, thanks!
More, more! :-)
cheers, Ian
With that 2.2kw spindle machine, take note he's changed all the electronics, and the steppers have been replaced with much more powerful ones!
There's no way the electronics/mechanics on a...
I wouldn't worry too much, you've still got a cheap entry level ticket into the cnc world.
Either it will do what you want reasonably well within it's limits, or it will just be the first of many...
I'm a bit dubious whether a 3040 is worth tarting up at all unless you can get the parts for practically nothing?
It seems a lot of cost and effort for very little return, as the 3040's inherently...
I've got a 3040 and a 6040, the 6040 is terrific value and quite a robust and well made machine generally, the only real downside is the garbage "blue box" controller they come standard with. Replace...
Thanks! not sure if I already had it but grabbed it to be sure.
I'm finding the Chinese increasingly better to deal with over time. And the fact they don't embrace the "charge as much as possible" attitude that is pretty typical among local sellers is just great,...
WOW!
That is beautiful work Ygorek!
Love to see how you finish it.
cheers, Ian
I'm assuming the market for parts and consumables in the States is somewhat similar to what is here in OZ, in other words very little stuff actually MADE in the States, with resellers/distributors...
It's great to hear getting into CNC has made a major change for the better for you!
I absolutely love anytime I go out to complete a job or just potter around on the latest design or project. The...
Beautiful work Ygorek!
Very nice carry chest.
cheers, Ian
I do a heap of this kind of work all the time and as others have pointed out, a cheapo laminate trimmer in a simple made table with the hole as small as possible, really is the far easiest and...
Hi Dejan, what an awesome job you've done on the machine so far, the castings in particular are absolutely brilliant! I'm looking forward to see how it progresses.
With my machine, no, I never...
I'm far from any expert but based on my experiences with mills and cnc machines, machining ferrous materials is very different to the run of the mill materials machined on most hobbiest machines.

I ended up going for the 6090A which came with qood quality linear rails on all axis, and unfortunately bought the obligatorily 4th axis for a hundred or so extra, which turned out to be a worthless...
As an owner of several Chinese machines, I can say they all have exceeded my expectations on build quality.
My 6090, not the table version, is a huge brute that just keeps on plugging away...
It might be a little more expensive up front, but once you use a G540 you will never regret buying it!
They are that good! And with bullet proof support to boot.
cheers, Ian
This is a much closer match:
Nema 23 Stepper Motor, 3.5A 300oz in. 2.4mh Inductance (1/4in Double Shaft)
Although around 2.3mH is going to be about the best achievable. As I stated before,...
You can get more optimal, bringing you closer to the max possible match, but those steppers are really good and will be more than capable of pushing a few hundred kilo's around!
cheers, Ian
