Now then all,
So after getting the machine all set up and working properly! im after CAM software with a decent post processor for either EMC or Mach3.
My lathe is the Boxford TCL 125
Any help is much appreciated.

Have a look at the Easymill, there is a turning package with that - the hobbyist version is £375. The commercial package is the same functionality but costs more - see RDLVLtd.weebly.com for more info and prices.Quote:

3D is to be released later on.
The majority of machinists work using no more than 2.5D systems.
Most hobbyists want 3D - but very few actually need 3D, 2.5D is probably sufficient for the majority of the work.
When I was looking for A CAM package I wanted a 3D capable system because that is what most people talked about - but most of the stuff I do uses no more than 2.5D, and a lot is only 2D.
I don't do Jewellery design which needs 3D, turbine blades for jet engines (yet! lol) which also needs 3D, and sculptures as I cannot sculpt - and as I don't have a 3D scanner (yet) I can't reproduce a sculpture.
There are a number of professional machinists who still program their CNC machines by writing g-code at the console! And many hobbyists too! A CAM package such as Easymill provides machinists with greater efficiency and ease of use. It takes me a couple of minutes to launch Easymill, modify my design and generate new g-code. And, if I don't use it for a while, I don't have to go through another tuition class to relearn it.
Is this that program where you pay per use ?
For hobbyists the version of the software is called Hobbycam - there are 150 post processing tokens per year - to my knowledge no one has yet run out!Quote:

I hope to post some more of my designs before too long - Easymill is quick to use, but I don't always have the time to use it and get to the workshop to cut my parts!
So the hobbyist has to be connected to the internet to post process ?
How does that work when the machines is in a workshop with no internet connection ?
One supplier of CAM software has already made this mistake and had to back pedal and move to a different system because of this problem.
So no internet connection, at either end, or a lack of continuity from the sellers end could mean you are out on a limb with a program you can't run.
Sorry not for me, at £375 there are better offering out there for what is a basic 2.5D program
Yes -the internet connection is required for PP.
Most hobbyists use MACH3 - so the buffer for the g-code is held within the PC. When I was researching how to drive my machine the advice was to have a dedicated PC driving the CNC mill/lathe. The reason is that Windows is non deterministic which could mean delays in driving the CNC machine. If you have a large g-code file which would result in several hours of cutting time - I would not want any interruption in the machining cycle because windows decided it had better things to do. I think that priorities may be programmed into Linux - but I don't really know as I don't use Linux.
At this time I still use the dedicated controller within the mill and have an RS232 cable between the mill and the PC. When I get my 4th axis (a axis) working I hope to convert it to MACH3, the upgrade cost for my mill for a 4th axis is too expensive for me.
So I use an old XP PC, dedicated machine to my mill - not connected to the internet or running any other software other than that required for driving the mill. I also have an all singing and dancing multi GHz, fast graphics etc. PC for my CAD/CAM work. I transfer g-code to my milling PC via a USB stick.
The commercial version of Easymill is £2500 and competes with the 'heavyweights' Delcam etc. but at a fraction of their prices.
There a re a number of commercial organisations who successfully use Easymill as their CAM software - and they do not consider it 'basic'. The sophistication is in the software itself - Are there other lower cost CAM software that eliminate chatter when cutting curves? Also for a 'basic' system it generates sub routines (if one wants to) in order to keep the code short and manageable, many of the 'heavyweights' do not do this, and I am not sure whether lower cost systems are capable of doing this ?
There are many parameters that may be programmed into Easymill to achieve desired goals - but not all are needed when starting to learn Easymill.
At a basic level it is quick to learn - about 2 hours, quick to boot up and modify a design, and if not used for a couple of months can be quickly remembered.
I had bought a £200 CAM software package for my mill, it was OK but it is very basic. I quickly outgrew it, Easymill will see me through for quite a long time.
If a hobby mill costs £3-7K (KX1/3 at £3-4K, Syil at £3-4K+, Tormach at £5-7K, home made £2K+) then £375 price for a CAM package would not be an unreasonable cost. After all one buys the best tools to achieve the best results - cutters etc. and one spends as much on required tools as one has spent on buying the machine e.g. DTIs, verniers, vice(s) (Kurt... v.expensive!), parallels, angles,
Mostly I find you get what you pay for ... (mostly! :-)
But EasyMilll cannot compete as it doesn't have the capability to do 4 & 5 axis as can be seen on the picture from their own website It's only 2.5D.Quote:

I've got to say I'm not convinced by easymill.
I've briefly looked at some CAM packages for turning (I'm in a similar position to the original poster), and Dolphin partmaster is the one that I'm favouring if they run another one of their hobbist deals, but for most of what I need to do for now, I think I'll get by with the Mach3 built in wizards.
I'm not sure about buying a CNC mill, but I think £2k+ is a bit much for a CNC mill.Quote:

Granted I didn't buy ballscrews, but even with that it's probably less than £800.
For me spending £375 on a CAM package just isn't happening. So far I've got along fine with a)writing gcode manually, b)writing my own programs (pulleys, wind turbine blades), c) cambam free edition and using the denford QuickCAM pro at school every so often.
You can do a lot with the cambam free edition with a bit of effort. Using that and CNCtoolkit and you'll be able to do most things. Turbine blades too....
You jest surely ?Quote:

That's a 3 axis program for the equivalent of £625

Aahh.... It seems there is another Easymill - the one I was referring to was www.easymill.com (French) or www.easymill.co.uk (English).Quote:

Depending on what you are going to use it for, you can get away with not using ball screws - if you can accept and remember to program in the backlash.
This is the lowest cost machine I have seen - Unless someone knows of an even lower cost machine.
I would not want to make repeatable items on this - probably just my prejudice :-)
My second hand mill - a Denford TRIAC PC - cost me £1500 complete. It claims to be repeatable to 5 microns, not that I would know!
But the original question was not milling but turning - Easymill.co.uk does have a separate package for turning. I have not used it yet as my Lathe is manual only at this time! But I may get to use it on the mill as the axes translate over.
BTW - Easymill.co.uk did have a special offer over the Christmas period as an introduction to the UK market, the Hobbycam version was £50 instead of £375 for a limited time - maybe they will do that again?

Yes those were the sites i was referring to, maybe you need some lessons on the differences between 2.5D and 3D/5 axis machining.

If you can't get the facts correct what credibility do you have ?
To do 4 / 5 axis the program has to have the ability to work with A and B axis, can Easymill do this
So... elucidate!Quote:

- 3 axis - obvious
- 2.5 axis - 3 axis but with Z only 'up' or 'down', possibly some in between but generally making 'flat stuff'.
I'm not sure how you could confuse that software with 4 or 5 axis. The terms are well defined.
Yes Easymill can rotate parts in 4 and 5 axes - but not while cutting.Quote:

And more specifically a great deal of confusion as to what constitutes 2.5D!
With Easymill as far as I am aware the axis is rotated but doesn't cut while rotating.
When the part has been rotationally positioned, the cutting starts in 2.5D.
Isn't 5 axis work holding and machine stability beyond hobbyists' budgets? So why is 5 axis an issue for hobbyist software?
I need many clamps just to hold the small pieces I do in x,y,z - so with 5 axes I am not sure how the work pieces would be securely held - unless I get a very expensive machining centre.
So it's 2.5+2 axis then I suppose, not true 5 axis software as you implied earlier. You could do what easymill does with the A/B axis yourself without too much thinking!Quote:

Have a look and you will see why the software is expensive
Phil
You say the terms are well defined - yet when I see responses on various forum sites and software manufacturers' sites I find different definitions - specifically between 3 axis and 3D - which you call obvious. It does appears to be - x,y,z. If you limit your definition to axes, as you have, then your definition is very clear - however where is the definition for 2.5D and 3D? This is what is confusing!Quote:

My machine has 3 independent axes - but I can only cut in what most people call 2.5D, I would need an A axis to rotate the part and cut all around it.
That was impressive - thanks for finding it and posting.Quote:

No you need 3D software which easymill is not, if you had an A axis as well you would have 4 axis but you need the software to do 4 axis machining.Quote:

This statement in wiki is confusing - A 2.5D machine possesses the capability to translate in all three axes but can perform the cutting operation only in two of the three axes at a time.
It seems to be saying that a 2.5D machine can only cut with 2 axes in operation, and the third fixed.
Yet the first statement indicates that it can cut at full 3D as long as there are no overhangs.
I'm probably misunderstanding - but feel the definition could be clearer.
By credibility you are selling a piece of software that you don't even know how it works.Quote:

So was there ever an answer to the software for lathes?
I am having fun lol not with lazyturn and miniture tank barrels everything was going well then mach3 just froze and lost the last tool path then decided to part the job
with a vcmt insert not a happy bunny right now and running out of scrap ally to play with grumble grumble
I am using DolphinCADCAM, (Partmaster)
It works very well with Mach3 and EMC2 (download the windows 7 patch and the PP files are in there)
I havent had any issues with this program and do recommend it, worth the buy imo
I tried a demo of Partmaster, but i absolutely hated it.
They do do deals for hobby users in which the price is quite reasonable.
So try the demo
Make sure STOP SPINDLE WAIT FOR CYCLE START is ticked in general config TOOL CHANGE
Phil
I use Dolphin Partmaster for mill but hardly for lathe, for lathe most of what I do I can get by with using the wizards in Mach 3.
These will be updated shortly so you can add to them, i.e stack them up so you can do a face operation, then turn, then screwcut.
Ron Ginger who's in charge of Wizards reckons he'll have them done for the CNC show in the US in June or July.
Partmaster is a two part program, CAD and CAM. CAD absolutely sucks, it's terrible and not intuitive at all. CAM is very good and if you bring files in as DXF's it works well.
I never got past the CAD side.Quote:

Phil,
I think if I'd have gone the CAD route first I would have thought the same but many of my jobs come in as DXF from the customer so I bypassed that.
Also I have a CAD package I'm happy with and had it in various versions for years, so it's more productive to me to alter a drawing in my CAD program, then bring it into Dolphin as a DXF.
John, I can understand your reasoning. I didn't have a CAD program hence the route i took.
I went with OneCNC and it's a joy to use.

M250 any chance you can put up a video of the proces to turn somthing that looks somthing like a small tank barrel from the cad throught to the cam and Gcode I have asked onecnc to get in touch but no joy so far and I know you use it and like it so I thought what the hell see if you would be so king to give me a look see.
Kai do you have Skype ? as i believe i can give a one 2 one demo using it "Skype" you can see my desktop on your machine, i haven't tried this so don't know how good it would workQuote:
