Chinese 3040T Arrives

[futura]

Hello JazzCNC

thanks for your post..

Hope this helps.

I would say thats an understatement!!

Yeah that really does clarify things a whole LOT. I really appreciate you taking the time out to write this as it has certainly cleared up many things for me.

I suspect any other newbies reading this will also learn from this conversation.

I wish your post could have been included with the Chinese manual that came with the CNC machine. :D

Just out of interest what software would you recommend?

For CAD design I want to make traffolyte front panels for my synthesizer modules I design. I was thinking maybe Signlab? but also I have Corel Draw and now I am starting to realise the CAD side of things doesnt need to be so much machine orientated am i right in saying for CAD you can almost use anything you like or get on with?

For CAM I am looking for something that is not over complex but can hopefully be smart enough to assist with not just engraving the synth panels but also cutting the holes for the potentiometers and finally cutting the panel. I have looked at a demo of vcarve.

For control software I think for now I will stick with Mach 3 but I am also all ears in terms of other options such as LinuxCNC or KKam etc.

I have a feeling I may hit brick limits in terms of actual cutting with the router ie it will engrave the traffolye happily but I am unsure of how it will perform in terms of actually cutting holes or cutting out the plate.

Im one of these people that likes to get a good understanding of what I am doing prior to doing anything. I know there is an argument to "get your hands dirty" and find out but for now I want to tread carefully and not break anything or waste money on unnecessary software.

Hope you dont mind the questions I am very interested by what people have to say on this forum.

kind regards :)

Anything will do, as long as it gives an output format that your CAM package can accept. Most things seem to be happy with dxf, for example.
My machine is probably about as bendy as they come and still be usable, so if I can cut hardwoods, birch ply, and so on I'm sure that you will be OK for what you are planning to do with Traffolyte. Good luck!

Just by asking a few questions here I have an awful lot clarified.

Its very interesting to hear about your experience with linuxCNC / EMC. I see it runs on the LTS version of Ubuntu. I have always liked Ubuntu OS a lot. When ever I have experimented with Linux I have always found that to be one of the more easier and forgiving OSes in terms of drivers and user friendlyness.

Open source software in terms of machining I can see as being very useful particularly if you have the ability to code and thus modify to your own requirements.

My only hesitation about going down the Linux / EMC road is I already have a bit of a project on my hands in terms of this Chinese Router ie no manual, no support and a hotch potch of potantial control boards / steppers etc. From my experience of Linux experiments it has always resulted in issues with drivers, limited documentation etc. I guess this is inevitable as the motives behind coding linux projects are not always customer / consumer driven.

However that said how did you get on with Linux/CNC and getting it talking to your machine? Was it fairly painless or a pain in the backside?

Maybe like with general OS installation if you choose an older machine with average and non complex kit / intel cpu / intel chipset and standard ports etc maybe no issues?

I assume there must also be CAD and CAM linux projects? Does these come on the Linux CNC Distro or not?

Cheers for your feedback once again great info :) TY.

You can find Linuxcnc here:- Installing LinuxCNC Just run the install cd and everything is done, there is a wizard for the initial setup of the machine etc with a simple interface for driving the machine. Also a touch off probe is simple to setup.


Re CAM I am not aware of any that will run on Linux. ..Clive

PS It would be good if Dean's (Jazzcnc) post #96 could be made as a sticky because that question is asked time and time again on the forum.

Oh if only I had a pound for every time I've been asked this.. . . Lol . . . . Honest answer is I can't tell you.? Every person has different needs and there is no one "Best" software.
If your into wood then Vectric software or Delcam's Artcam express are good ones to look at. If your into Metal then they are limiting so you'll need software more focused on metal and cutting stratergies more suited to that type of work. Dolphin CAM, BobCad/CAM, Solid Cam, etc
Then you have CAM more suited to 3D like Deskproto, Meshcam etc.

I'll explain CAM a bit more and hopefully you'll see why there's no "best" software or one does all.!
When working in CAM and defining the toolpaths for your part you are working with Cutting strategies. CAM software provides cutting Strategies for each process to define the complete part. So Holes would use Drilling Strategies and within this strategie you would have options ie: peck drill, straight plunge etc you would also set other parameters here like drill size and feedrate etc.
Some common strategies are, profiling, Pocketing, Surfacing, V-carving, Engraving etc. These are mostly 2D strategies but there are also 3D which take you into other areas I won't get into now has it would take all night.
Better software gives you more Strategies along with more parameters within them which enable you to get the exact results your looking for. This is esp true when it comes to 3D type work.

Now Wood working bennifits from specific strategies designed for that type of work, so they will have features like Nesting, or abilty to add Tab's to hold work when cutting thru. Where as Milling metal doesn't usually involve more than one part at a time so these would be mostly unused so waste of money but as other requirements like how it enters material that equally would be wasted in wood usage.

So bottom line is while the cheaper software may look ok they can be limited in the options and parameters they provide. This is why you need to look at the type of work your going to do.
If basic stuff like drilling and 2D profiles, pockets etc in softer materials along with V-carving, engraving etc then most of the cheaper end software designed for wood use will fill the purpose. If on the other hand your looking at 3D work then you may want to spend more money and get package that offers more cutting strategies.

It's for these reasons No package is best or can provide everything for every situation other wise the cost would be massive.

My suggestion is you stick with something that is cheap or free until you know better what your cutting and what's required to do it, then splash out on better software when you have some experience. CamBam is a good all round software that is free or cheap.

For CAD design I want to make traffolyte front panels for my synthesizer modules I design. I was thinking maybe Signlab? but also I have Corel Draw and now I am starting to realise the CAD side of things doesnt need to be so much machine orientated am i right in saying for CAD you can almost use anything you like or get on with?

Mostly yes but the CAM software will dictate this to some degree but most accept common format's like DXF for 2D files and STL for 3D. Coral draw is a good one as it's Vector based which is a common format for most 2D CAM packages.

For CAM I am looking for something that is not over complex but can hopefully be smart enough to assist with not just engraving the synth panels but also cutting the holes for the potentiometers and finally cutting the panel. I have looked at a demo of vcarve.

Again down to the cutting strategies provided but just about all CAM packages provide pocketing or profiling strategies so this won't be a problem.

For control software I think for now I will stick with Mach 3 but I am also all ears in terms of other options such as LinuxCNC or KKam etc.

Stick with Mach3 it's the best for new users, loads of support from other users and simple when setup.

I have a feeling I may hit brick limits in terms of actual cutting with the router ie it will engrave the traffolye happily but I am unsure of how it will perform in terms of actually cutting holes or cutting out the plate.

Don't stress over it and just feel your way thru the work, the machine will soon let you know if it's not happy and from here you'll find the best cutting conditions to suit your machine and material. Each machine is slightly different and what works on one doesn't mean it will work on another. This is also true of materials, I've cut aluminium that is supposedly same grade but from different sources and it needs working at differant feeds speeds etc for best results. This is what I mean by tweaking on the Fly in control software while cutting.!

Hope you dont mind the questions I am very interested by what people have to say on this forum.

Nope that's why I'm here, to give back or pass-on what was given freely to me.!!
