How much should I expect for such gear?
I'm expecting to pay around 1500$ for the bending servo and gear as it's the biggest one and it's about few hundreds dollars for the other axis servos, it's...

Yes of course, it's gonna be translated like that, the question was more, according to you guys, what would be the most convenient source to extract this information, STEP/INGES file ? or I don't...

at the begining I wanted to reuse the dies from my manual bender but no way it's not gonna be possible, so it's ok I will draw it and there is a workshop near my house that can machine it.

What...

Actually I will develop the software so I'm not gonna use LinuxCNC but an Arduino based PLC, so I'm trying to know how commercial solution does to go from the design (for example Solidworks) to the...

After a lot of research, I found this actuator reference from Nabtesco:
https://precision.nabtesco.com/en/products/detail/AF-N

So it's a geared servo motor, they even mention the Tube bender use...

I also saw those solution but I would prefer to go full servo drive, I should have been maybe more accurate but what I'm building is a mandrel cnc bender.

I already solved the problem of feeding...

Yes it's still, I have been a bit busy with some other stuff, and for some reason I don't get notification, so I didn't noticed I was getting response ;) thanks for your help

Hi all,

I have questions about standard format accepted by CNC, for CNC Plasma Cutting, I see DXF or GCode as the most common, any clue why LinuxCNC seems to accept only GCode?

What about tube...

Totally missed that point, I didn't read properly ;)
Seems to be a more reasonable solution :)

Do you have any references to recommend?

anyone has an idea about it?

In addition, I found this article that tend to confirm my thought:

the bend can...

I was looking a CNC like that:

I'm not 100% sure but this kind of CNC seems to use Servomotor, and I'm not sure it's really relevant to speak of...

Yes it's correct I'm looking to build a real CNC as I explained in first post, so after the bend part solved, I will build an axis positioner that will push and rotate the tube to the next bend...

I don't think it require a gear box as the speed of a servo can be controlled, and you are right it's going to be more around 2-3rpm.
I want it to remain quite compact and using a gear box is not...

It's a CNC rotary bender (mandrel) that I want to do, I start with the bending part and later I will do the axis positioner, and of course the whole actioned by servomotor to achieve accuracy and...

Hi All,

I'm starting a new project, I want to build my own CNC Tube bender.
The idea is to build the machine fully controlled by servomotor and everything controlled with Arduino.
I would like...
