Thread: Fusion 360, Mach4 and first test of cnc router

This is a common problem in Mach 3.

You'll probably need to change the I&J arc centre settings, either in your post-processor or within Mach settings.

I was posting an adverse comment about Blowlamp’s video but that seems to disappear when quoted.

It's not my video.

It's one I came across that puts a Doctor's assessment over. That's all.

How about fitting a DRO? That way you can work in metric/imperial and by radius or diameter


Thread: CAM software for CNC Lathes - With C axis and constrained live tool
04/01/2021 19:43:52

Thanks Martin - I will get Ecam and learn - At least those lessons are more main-stream than LinuxCnC!

I do have the PlanetCNC's TNG software - Early this year I looked quite deeply into the PlanetCNC stuff as I was looking for a MACH3 alternative to drive my 4 axis hot wire foam cutter, and had good discourse on the Planetcnc forum. The software was able to do it all just fine, and I was ready to procure the controller and TNG software, and the virus arrived, shipping stopped, etc - I did not revive that route as my lathe project woke up in all the lockdowns, and so the research regarding able controllers started. If the Planetcnc board can do my C axis lathe, then it is really a no-brainer - I will persevere with LinuxCNC, but right now , only because It is a challenge, but to what end I am not sure. As I said before, the Centroid ACORN and the PlanetCNC boards and associated softwares are just so polished - the software user interface, the look of the machine screen, layout, etc is very professional, and looks 'machine tool' like - MACH3 is so poor in that regard, and LinuxCNC is not a huge improvement - I know both can be changed - you can create your own screens, setups, etc, but again, that's not the objective for a machine user is it?

As it is, there are big learning curves involved as soon as you start in the CNC realm - finding and learning an (affordable?) CAD package, ditto the CAM software, setting up the machine, etc - And then the Controller software it self - TNG, the Centroid offering, LinuxCNC, etc, also has to be 'learnt' so spending time learning the inner guts to just add handwheels, etc, is not useful at all!

Martin, your video is very good - you have done a few videos I see, and you do them well! A natural! - My very few videos are silent movies - with some titles if I think it needed - but I would have to read from a script to voice it! - too many umms and aahhs.

Thanks Again for your help.


Thanks, Joe. I'm very happy if it helps with your project.

Just ask, if you think I can assist.

Moment of Inspiration (MoI) is what I use. It is a very well thought out CAD package and is super for drawing complex lines & curves easily.

Just a bump to a moderator please - If you would be so kind as to delete the now space wasting G_Code posts -

No-one else will have much interest in them and they will annoy fellow readers I think..


Edited By Joseph Noci 1 on 04/01/2021 07:43:58

Doesn't annoy me, but if Martin drops me a PM confirming it, I'll delete the G-code. Your question but Martin owns the answer, and his post is within the rules. Harmless, and I expect a few people may have been interested in what G-code looks like. No obligation to understand it, or look at it at all.



I don't mind one way or the other. I'll leave the decision in your capable hands. smiley

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.


03/01/2021 20:19:35


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.


30/12/2020 16:33:31

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

30/12/2020 13:04:53

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.

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?
