Hello! I am building a new CNC machine, my first machine actually. 3 axis machine. It will be for machining steel mainly. May do some aluminum, plastic, or wood as well. Precision is more...

no input??

Ok.. I have not bought any electronics or any motors or any parts at all at this point. I am still in the research and development phase of things!
I want to mill copper for the most part, with...

Hello! I have been dreaming of building a CNC machine for quite some time now. Today is the day that I actually am going to start putting money on the table and ordering some parts to put this...

Thanks again for the replies, all.

I would not be using pneumatics if I went the piston driven route.. it would most likely be hydraulic oil, or possibly water. Definitely not a gas. If I...

Yes, I understand that I have a lot in front of me. As a wise man once told me.. how do you eat an elephant? One bite at a time..

As to the overshoot issue.. I would hope that the driver or...

Wow what a wealth of information that I really don't know what to do with.. Thanks everyone for your input. My gut feeling is that I want to use an absolute linear encoder.. This way I don't have to...

Al.. would you mind telling me what your complete setup consists of? How did you accomplish closed loop, what motion controller, what other boards are required, and what motors? thanks

Don't get me wrong.. I am not looking to reinvent the wheel or anything. I am relatively new to the cnc world and am still putting the whole process together in my mind.

So If I was to use a...

Thank you for the information.

Yes, I am looking for some type of closed loop control. I don't want the closed loop feedback to necessarily be from specifically a servo mounted encoder.. I...

So you are saying I cannot use Mach3 with linear encoders or "kfkop board"? not sure what that board is but I will look into it..

I am kind of new to the whole CNC thing, but have a strong electronics / electrical background.
Basically.. I would like to build a CNC machine that uses an outside sensor to tell the CNC program...

Most places that ship to usa will also ship to Canada, so if you know of any good places for usa then i'd love to check them out.

That type of interlocking profile is known as dovetail... that might help you in your search?

Any advice for a reputable place to purchase?? Any good websites you can recommend?

Hey. I am in Ontario, Canada.

Hello. I would like to find a place I can buy good quality rails and guides above the 1 meter length for x axis, and guides / rails that will support a decent sized load for Y and Z axis.. I've...

Thanks for another great quick response and a straight forward answer. Many pleasure filled nights be sent your way.

Building a 3 axis cnc machine using stepper motors.

For the Z axis, the rotary cutting tool will be moved vertically. When the Z axis is not being told to move by the software, I am assuming...

Hello. Plan on building a CNC machine capable of xyz axis milling of wood / metal. Plan to use high end stepper motors with high quality drivers such as "surestep stepper drives". I'll also be...
