with the 7I96 i know is linuXCNC is this a bad thing? it was what i am planning to run (i know nothing about cnc soft where) as i have heard good things but am I wrong?
Regards an alternative kit then NO there isn't any that can do this at this money, why.? Because it's impossible for anyone(Even the Chinese) to make money and provide the correct components and a frame strong enough for cutting aluminum correctly at that money.

To cut aluminum properly with correct feed rates, depth of cut (DOC), and give a good surface finish requires a strong machine, which uses linear rails, ideally profiled linear rails, Also ball-screws with correct end bearings. The frame and Z-axis need to be very rigid to handle the vibrations, steel or at least heavy-duty aluminum profile are required.
The WorkBee or any of these Shapeoko type machines with their flimsy frames using narrow profile sections running on Rubber V- bearings with elastic bands for linear motion are simply a waste of time. Putting ball-screws on them is like putting lipstick on a Pig.

Now I know you will have seen videos of them cutting Aluminium, but what they are not telling you or showing you is the effect this is having on the machine long term. Often they are also not telling you how long it takes scratching away at it with 0.25mm DOC. They are also not telling you how it hammers the machine or the shitty finishes they get if they try to take anything like correct DOC etc.

These machines seem cheap but they nearly always end up costing you more in the long run for a number of reasons.
#1 You'll throw money at it to upgrade the frame in an attempt to combat the weakness's but this is folly because you can't make a silk purse out of a Sow's ear. The frame is junk.!
#2 You'll upgrade the Electrical in an attempt to give it more guts, this is pointless because the frame can't handle more power.
#3 You'll try to upgrade to linear rails to get rid of those pain in the arse V-bearings, again pointless due to weak flimsy frame.
#4 You'll upgrade the elastic bands to ball-screws, pointless because the frame is junk so the extra resolution and accuracy is wasted.!!

Hopefully, a theme is appearing now..? . . .The frame is the foundation of any good machine and if it's weak then anything you upgrade or attach to it in an attempt to make it better is wasted money. These frames are Junk and all of the components are inferior or weak.

The best advice I can give you is to save your money and build something yourself from steel/aluminum and with the correct components. Or if you haven't got the tools, time or ability to self build then wait a little longer and save up and have someone like my self build you one.

I promise you this, if you buy one of these WorkBee's then you will regret it long term. They are great for learning on if cutting woods etc and often quickly outgrown but they are useless for cutting aluminum and will disappoint you quickly.


Clive answered the Linux CNC questions. But again I'll warn against going the cheap route on controllers like the Arduino or GRBL setups. They will be limiting and frustrating for a first-time builder.
End of the day if you want to do CNC successfully you can't cut corners or do it on the cheap. It's THE BIGGEST MISTAKE new builders make and ALWAYS ends up costing more long-term or worse puts people off CNC altogether.
