Limited demo version. Also can run in simulation mode with no machine connected.
I have the free download for Mach 3 and it runs the mill and lathe fine.
There are a few more restrictions over the $ version, such as the number of lines of code you can input and you can’t pause and continue from that point on afterwards, but they have never been in the way.
For the investment in the Sherline, the cost of the software is a pittance. These guys aren’t getting rich, I don’t mind steering some $$ their way and there will be no surprises when I get near the limits of the free version.
So far everyone involved has bent over backwards to help and support me, so I don’t mind returning the favor.

Greg,
A question for you…will your mill be a full function three axis (XYZ)? Th reason I ask is that when I watched a couple of Sherline’s demo videos, it looked as though the “operator” was moving the quill manually. There is a rotary axis accessory, correct?
I’m very anxious to hear how your learning experience goes with your new mill :).
Yep, it already is 3 axis, and I will probably add the rotary indexing head to it later. The motion electronics I have will take 4 drives.
I think the rotary axis is about $600 or $700… . I am almost salivating at the possibility to make gears easily.
Greg
Greg,
The 4" rotary table is invaluable IMO. I’ve used it to make small parts in the horizontal plane many-many times. Sherline also offers an Indexing Attachment, I haven’t had the need to make gears thus far. Sherline equipment has served me well.

Actually, I find the toughest thing is how to hold your “work” securely without scarring it.
This is where creativity is necessary. Invest in some good forms of clamping and leveling mechanisms.
Well, got the Mach4 controlling the unit. The mill, the usb interface and the software all have independent instructions, and they all “conspire” to make a system that does not work.
I’ll be posting the recipe for success on my site. Anyway the support from dPP engineering was great, just 2 emails solved the problem, which was basically being provided with the wrong drivers and configuration.
Now I need some tools. While the system is provided with a holder that uses a setscrew to hold a 3/8 mill, it also comes with a 1/8", 3/16" and 1/4" collets.
I need a mill that is about 1 mm, so I’m figuring I want to use the smallest collet here.
Where’s a good place to buy quality mills? I don’t want K-Mart or Nieman Marcus, but Nordstrom is ok, better to use good tools that are a bit more expensive for me.
Greg
Greg,
Try MSC Supply. this is where industry buys its tools. they offer several grades quality levels for most cutting tools. https://www.mscdirect.com/
By the way, which mill did you purchase? it was not immediately evident.
Thanks

MSC has but eleven 1 mm mill bits listed. Suprise…, only $92.20 to $124.14 each!
And they it only fit a few sizes of metric collets. No idea what collets you would use.
Also, I would recommend that until you are familiar with your machine, you hold off on the very thin mills, because it is very easy to break if you “crash” the tool, or even try to go too fast/too deep.

BTW, once you purchase from MSC and get on their e-mailing list, they have regular specials, often 30% or more off with free shipping.
My adventures on mills is on my web page:
They don’t even tell you what sort of collets it uses? You may be very limited.
Todd, I have no idea why you insist on following me around and only posting negative stuff that is actually not well thought out.
Your other comment is why would I pay money for software when I can use a limited version free?
If you spent time reading you would know the taper of the headstock, it’s on the Sherline site, if this is what you are asking.
On my site, I did list up the collets supplied, 1/8", 3/16", 1/4" and also a holder for 3/8" mills. That right on the page I linked.
All the information is easy to find on the Sherline site.
Are you really trying to help and contribute, or just looking for things that I have “done wrong”?
Greg
Gregor, I had a sterling cnc mill and passed it on…only because I felt I needed the ability to do bigger stuff…what I got since is pretty good but not way better. The sterling is a great machine and showed me good service. I scratch built a small live steamer on it…wheels frame and more wrestling well made. I did go through some end Mills though! I would buy several at a time, even double enders and still sometimes needed more. 1mm is small. Take special care! Get a bunch of them and practice before cutting into your golden part! You can have a lot of fun with it!
Yep, I’m going into this assuming a make a lot of mistakes and will break stuff, but when I was exposed to this before, at Hewlett Packard, it was great fun, and the CNC part is working nicely now, I might just use that initially to make long straight light cuts, which should help me not try to hog stuff out with a 1mm mill!
The cool thing is the factory is 2 miles from here, and they are way helpful, and they have a machinist on site always available for questions.

Greg,
At the least get yourself a couple of 3/16 and 1/4 endmills, flat bottoms and a stubby flute length. 2 flute and THEN do some playing around and experimenting. Best way to get to “know” your mill and it’s potential. Cut down on the varibles. That .949 cutter would be trouble for even the most experienced machinist :)! Every machine is "different (even in the same brand and types). I used huge hydrotels early on in my trade and right up to the last few years of my career. These mils weighed any where from 5 tons up to 50 tons with 30 to 50 H.P. and everyone one of them acted a little different when cutting. These were all hydraulic in the three axis’. Getting the proper “feel” during the cut and turning the handles, became a real concept to master. One thing it did do was to get the die sinker to properly set his feeds and speeds correctly!
They gave me a set of six 3/8" end mills, will get some scrap nylon / delrin to play first, then probably some chunks of soft aluminum.
I’ll play with feed rates and spindle speeds… hmm… since it’s a variable control, any sense to buying a cheap optical tach to read actual rpm?
The feel is a little affected by the steppers, but it’s not bad… everything turns very smoothly, and no huge backlash. I got the extra cost “zeroing” handwheels. All 3 axes feel good to me, remember I was using an older Unimat 3, which is smaller and has a lot more slop.
I think I will have to be careful with a larger motor to not try to cut too fast, the unimat would usually slow down before you got in trouble ha ha!
I did learn on large bridgeports, but that was in the late 70’s… but funny, the “feel” sort of comes back pretty quick.
Greg
My next task is to get one or 2 dial indicators, one for testing squareness/setup, and the other for general measuring.
Found some nice stuff, abotu $200-$300 each, wow, but I guess these will last a lifetime… of course I don’t want Chinese, since I’m old school German / Swiss… looking at the Bestest, carbide tip, etc. the 0.0005" stuff…
Starett was suggested, which I’m sure is good enough for my very limited abilities.
My 0.040 carbide end mill is arriving today, we’ll see how it works.
Greg
Wow Greg, you aren’t wasting any time. I’m enjoying checking back on this every couple days. I’m beginning to think I should have gone for a smaller machine like you. Here are my big machines that I got moved this weekend. Now just one more move for the “little” stuff.
That is SERIOUS.
Yep this is fun, and once the shock of the initial purchase is over, then the accessories just start rolling in!
Got my little itty bitty 0.040" mill today, 2 day delivery from McMaster Carr.
Greg
