Also consider CNC repair (like a mechanic), CNC improvement, CNC retail, etc.

It will really depend on where you are, who you are, and wht you already have.

(if you own a big huge truck or van, you can transport machinery in it, for example)

Perhaps refurbishing old machines/reselling scrap machines would be more lucrative.

The world has lots of old machines.

For example, my late great uncle has (had?) an old metal lathe, which could be converted to CNC.

hi dear friends
i have this file.ngc which is used to produce a workpiece in series.
my issue is that speed does not increase . even when i change #4 parameter in file,ngc
i tested g0 and g1 in mdi and machine moves in 4800mm/min speed without any problem but when i run this file.ngc code, speed is limited to 130 roughly 

Removed speculative reply, potentially useful though it may have been.

Hello friends, I'm new to the group and want to thank you all for your work and for being a helpful, knowledgeable community.
  
I'm interested in what I'm learning and would like to know what career options use this knowledge.  I see some guys mentioning that they've built cnc machines for years - I find that intriguing.  

It sounds like they have their own business; if so, how can I learn about setting up such a business (costs to get started, market in my area, projected income, etc).  I'm considering an engineering or software development degree but this is a career path I'd be interested in following if it continues show good chances of success after careful research.  By "success", I do NOT mean that I require a wealthy income, but 50 hr work weeks for $40k/yr net as an established entrepeneur - that might not be the best success option for me.
Thank you for any insights

You have to compile the component again.

yes, I meant pin numbers as they are shown in the I/O column, but you are right I had a mistake as I tried to configure pwm1, but I experienced the same behavior with pwm0 on i/o pins 7 and 9.
if I use multimeter I see between 2,5..4V signal on pin6 (depends on the value, of course) but nothing on pin8. (corresponding 50pin numbers are 13,17)
/enable signals work properly.
thx

Mesa 7i95T or 7i97T would be all in one, but price might be on the high side for what you need.
You can safely use just a Mesa 7i92T, but must be careful with wiring as the pins are sensitive.
Having said that, i have Mesa 7i92 wired on several of my plasma machines, meaning very high interference environment, and the THCAD is wired with 5-7 meters if cable directly to Mesa 7i92 input, yet i never have issues, ever.
This does imply proper shielding and grounding is a must.
In your case just having good shielded cables and grounding the shield only on the Mesa side inside the box should be fine.

Are you sure you have the pinout correct?

PWM 0 uses 50 pin connector pins 15,19,23

I'm with you, like most of us probably. People like that come and go.

My advice would be:
1. Don't get your blood pressure up, it's not worth it.
2. Only clarify wrong statements that are relevant to the question at hand.
3. Ignore the rest of the babble.

Thanks for your help, that was the problem

Hi everyone,
I bought this device: SG-ELC-ADIO-DI16-DO16-PNP.
I wrote a custom XML file for it, but for some reason, after I load it, there's a 90% chance that EtherCAT crashes with an error.
I suspect that it might be slowing down the entire system, or maybe I wrote the XML incorrectly.Here’s what I wrote:

And I’m also attaching the original XML file.

as per manual there is only one variable receive and one variable transmit PDO : 0x1600 and 0x1A00.
Each is limited to 10 entries.
You should see some error messages in /var/log/messages.
If you need more than 10 entries, you can use SDO instead of the 0x1600 PDO.
SDOs can be queried/set with "ethercat upload" or "ethercat download".
SDOs are permanently saved to the servo controller, so this is useful for nonchanging config parameters only.
