Thread: CAM software for CNC Lathes - With C axis and constrained live tool
03/01/2021 21:01:23


Get Ecam here

Ecam is free at the weekend. You can get your job set up and tweaked on the week days and generate code at the weekend. Never the less, I've bought a full licence because I like the software and I've had a good response from the author when I've found bugs etc.

Same goes for PlanetCNC. Have you downloaded it yet? It has an unlimited simulation mode that does everything except drive a CNC machine. I test my code with it first before going into the workshop.

Get it here and run it on any platform including RaspberryPi.

There are other Post Processors for Doosan, Mori-Seiki and Mazak, but you can modify one to suit your own machine too.

I have tweaked the Post Processor for my lathe (PlanetCNC) and get perfect code that I am 100% confident with.

Here's the video of Ecam doing some Lathe & C Axis work. It's a bit slow in parts, but should (hopefully) still get the message across.

For now, here's an older turning video I made which shows the basics of Ecam.

A quick reply.

I have Ecam with Turn, Mill and C axis options. I have a 2 axis lathe and so have NOT used the C axis feature within Ecam as I don't have the hardwear to support it. I do have a 4 axis mill, but Ecam only supports 2.5 axis features. I use Deskproto for 3d work on the mill.


I have PlanetCNC on my lathe and will refit my mill with it too, when I get around to it.

PlanetCNC supports up to 9 axes, has very extensive toolchange features and seems (to me) to be just about one of the most configurable controllers available to the hobbiest market.

The PlanetCNC person who said they had a lathe with all the facilities you wanted is Mr PlanetCNC himself (Andrej, I think). He is a very, very capable individual, in that everything is created by him - both software & hardwear.

I'll try to make a video of Ecam creating a part under a C axis setup. It might be something we can both learn from. A quick play yesterday soon made a hexagon (internal or external) on some lathe barstock, as well as various hole patterns etc.

Fusion 360 CAM might do it - maybe their business model wouldn't suit you though.

Ecam is set up for lathe C axis work. It can only drill, chamfer and tap radially, but can mill/drill almost any shape coaxially to the lathe main spindle. I can try a part if you give me an idea of what you may be doing.

PlanetCNC is as capable as LinuxCNC. It has a max step rate of 110 Khz, so that may limit spindle speed resolution, but there could be ways around that.

If you're going to reposition your milling spindle between axial and radial then it's a trivial matter to switch Profiles within PlanetCNC to reflect that change - it takes only a few seconds once they are set up.

Making these stamps sounds like a nice job for a CNC milling machine.

Try Libre Office. It is almost indentical to MS Office and requires very little relearning to use it. It's free and available as 32 bit or 64 bit.

And now a new variant has been discovered and is spreading rapidly through southern England! surprise

Could we be any more unlucky?

Thread: Hacksaw blade orientation - your opinion please
12/12/2020 14:50:26

I'm interested in the Femi claim that reversing the direction of blade travel makes their saw cut ~ 60% faster - how does that work, I wonder?


12/12/2020 14:39:16

Any blade that is under tension must surely be cutting on the pull, no matter from which end of the blade a person or machine drives itquestion


Thread: Message from ARC to our customers in the E.U.

Once the EU and the UK Gov see the effect this has on small business like ARC, they'll remove all these new regulations. roseheart

They'd never risk their people losing all they'd worked for just so Gov's could spite one another over Brexit. rainbow

You could use a Dremel type of tool with a cheap diamond cutter to grind your way through or maybe a diamond core-drill like these here

To be on the safe side, maybe have a scotch egg before travelling or wait until next week for a life-saving jab.

The neat thing about using a rotary edge finder - and in particular along with a DRO centre function - is how the centring accuracy 'homes in' if you repeat the procedure once or twice.


What's a DRO ? smile d

It's a Digital ReadOut.

Just for information, they usually have a centring function whereby you 'touch off' the first edge and zero the display, then 'touch off' the opposite edge (the reading might be say 37.42mm), press the Half button (centring function) and the display will read 18.71mm. Moving that axis until the DRO displays zero now means you are at the centre of the part.
