Hi.
About the cooling, well yes I use pcd, vacuum brazed, electroplated, sintered diamond tools. They all need a lot of water to "stay cool".

On the topic for the auto pressure foot spindle mount. I was thinking about buying one. There will be no problem for the bearings sliding on the material, if they are aluminium or poliamid. BUT as MN300 wrote, there is the problem with removing the background around the letters, which is the main method for engraving in my region. I believe that the engraving will mess up when it starts to work on area where all the background is removed and also the marble pieces that will be left behind from the material will be carried around from the bearings on the polished surface.

About the surface mapping. This is an interesting topic. I will try do some next week. From what I saw on the hundreds of videos that I watched, I think that the mach 4 feature will be most suitable.
The reason behind my thoughts, is that most of my projects are made by few different tools. For example, I use pcd for the clear contour of the letters - this is one g-code, and after that I use vidium tool to remove the background - second g-code. So if I need to make the scan over and over with each tool (each g-code) it may cause differences and loss of time.
What I am saying is that I haven't tried autolleveler or g-code ripper yet. And I am not sure if there is a way on both of them to make a tool change without having to re-scan, the surface.
The g-code ripper has a nice feature - the offset of the probe from the tool. Not sure if the others have the same function.

This video gave me the idea to make a permanent mount for the probe on the machine. So if I don't need to change the tool between the different jobs, I will not need to put the probe on the spindle. The probe will stay there on the machine and will wait for doing what its made for.

Thank you all for the ideas, it is really great to get some advice when you do something you haven't done!

Ok I made this /the attached picture/ , based on Craig's drawing and from what I saw on the videos for Gcode ripper. I just made some mistakes and cannot mount it on the spindle head, but I will change the mount will be ready soon.
The flexible spindle mount or the spring nose cone are both very cool ideas, but I engrave the granite slabs on passe. For example if I need 5 mm deep engraving, I make 10 passes of 0.5mm. otherwise the pcd tool brakes.

Hi,
I think I have decided for to use mach4 for the new build. Now I have a few questions...again...
1. Craig are you using mach4?
2. Can I use mach4 for my 4 axis machine? I mean is it stable with four axis?
3. If I invest in mach4 industrial, I will be happy. But, I read some topic about the hobby version having the probe functionality, and the industrial only having preparation for installing macros  from companies that sell probes. Do not know if this is real news.
4. If I pay for industrial, I need to get a good controller and BoB. What would you guys suggest?
5. What pc should I aim for. Motherboard? Memory? Video? Ssd? Windows 10? Processor?

Sorry for the tons of questions, I am really a noob, but I want to leaen. And for my work I really need four axis and surface mapping...

Thank you all in advance,
Peter

This looks interesting and if I understand, I will be able use it also with mach3. This looks like a good price even to test it on my old machine.

Hi,
I dont want to use windows pc, but it is the most flexible platform, for further development in time.
For now, I just need controller that operates with four axis, and have probing features for the uneven material that I work with. I thought that mach is the only way for me. Now I see UCCNC and see that there more and more alternatives.
What would any of you, use for this kind of job?
For the old machine, I am going to do the probing/ digitizing with mach3, and hope to succeed.
For the new machine I begin to wonder what should I choose?

Again thank you Craig, for helping the noobs like me. Until I am ready to do some tests of my probe, which will be next week, I want to ask an off topic question.

A friend of mine is building different kinds of machines and he is going to build me a new cnc machine with my financial and physical help. The CNC will have forth axis - "A". I still want to be able to do measuring with probe, not that I had done any, but I believe I will. So me question is:

 - Should I make the machine with mach3, because of the customization possibilities and the third party software that you can install on the windows pc, or should I choose something else.

He told me that we can use DSP, Syntec, Mach. He is more of a mechanic and less software guy. But he helps me a lot.

So to make it more clear. What controller should I use for 4 axis cnc and should I use mach3 or maybe mach4 just for the customization that I can always make, like the probing that we are talking here?

Hope that I wrote it understandable.

Second post.
So look what a friend gave me.

https://www.keyence.com/products/sensor/fiber-optic/fs/models/fs2-60/index.jsp?search_dl=1

He told me that this is some scanning device from a 3 axis cnc from Italian company Marmo meccanica.
It is a digitizer in his opinion, but the machine is unknown, he bought from an auction and there was no more information about the device and the machine.
There is something I found in another company portfolio and attached a picture.

My question is - has someone seen and used something like this on his CNC? Is is possible to adapt something like this to Mach with third party software? I am just curious.

Hi to everybody! I will make something like double post.
First, to Craig about the car and the cnc mill. Yes I need both for my work and I make some money thanks to them.

Second about the switch, I bought one omron switch, and going to make something like Craig sketched in the beginning of the tread.  Then I will try with autolleveler and see what is going to happen.

Ok. So... Tomorrow I will go to a omron shop near my city, or maybe call them on the phone today to check price and availability. The switch will be found and bought, hopefully. I am getting the idea of what I need.  Low current, sensitive switch. After this I will make the mounting bracket. So the thing is that I have to decide what to use, and since the autoleveller is free I will try it. About Mach4, the feature that Craig linked a video, was the first thing that caught my eye, when I was searching for a solution to my problem. It looks nice and easy and just the thing for my need. But, I am using parallel version of Mach3 on win XP, and I have no idea if the transition from one to the other will be smooth. Otherwise I am ready to pay for Mach4 license and parallel port plugin - 225 USD in total. Just wasn't thinking of doing it now, but as Craig said maybe I will go mad and beat the rush
Again thanks to everybody for the will to help.

Peter
