Good night guys my name and Nivaldog43, I'm starting today, I found this post on Pinterest where I participate, I entered the site I really liked the CNC article that uses Rectangular tubes of weldable irons, I have in mind to build a CNC with these types of materials that are cheaper than aluminum, it is more reinforced depending on the wall thickness of the Rectangular Tubes, I have my appropriate tools to carry out this form of project, and I would like the moderator if he is not uncomfortable and if he can pass me the measurements he used for his CNC for me to have an idea of ​​how much I will spend on footage of Rectangular Tube Iron Bars ... Thank you in advance ... I look forward to it.
