Mesa card + linux cnc sounds like my best option. The other project may be like a scara robot, or a continuum actuator where the "spine" is flexible, and would receive position feedback from external...

Thats true, I'll use electronic gearing of atleast 4. Is a mesa card still my best bet? Do you have an oppinion of running linux CNC on the BBB? They have hardware acceleration through the pru...

Hey! I'm building a 4axis (so far) CNC mill, but feeling a bit overwhelmed on which control mechanism to use. My motor/drives are DMM Dyna2 for the three linear axis, and a harmonic drive with a...

Wow, yes I do. I did not realize the torque required. I was not planning on using gcode to make my life easier (kind of)

Yes, I'm 20.

Wow, those are some very different numbers than Iw as expecting. I did not realize a motion controller is so complex, it is not optimal real time control, such as to minimize the jerk...

I'm thinking at some point I would like to build a 5 axis mill. I was hoping to get some feedback to see if I'm off my rocker.

The basic idea would be to make a large weldment frame. I would...

I have a 5x12' techno isle 59120 with a 5hp atc spindle and a 20hp vacuum. I am not impressed, and would not recommend this model atleast. The ballscrew is used as a support rail and the rails on the...

Yes, they sound nice. i'm interested in a few possibly

I have a timing pulley, but I'm not sure of its time. It appears very close to an L style pulley, however the tooth profile is slightly too deep. It is 2.5mm rather than 2.1

Do you have any advice...

I can't see the pictures :( I cannot sign up for an account without understanding enough dutch to answer the security question.


EDIT: I made and account and that is awesome. I will definitly...

I like the casting in layers idea. I could just wait until it cooks and then cast the next layer, I think this would allow good bonding between the layers aswell.

Why can you not machine epoxy...

I find that video very interesting. However, I am still wondering, how do you maintain everything square? Can you machine epoxy granite or will it find a way into the ways of your machine and destroy...

I will definitely practice using concrete instead.

When machining molds entirely on a lathe I can see how everything would come out well.

My worry is about when assembling it out of individual...

Hey everyone,
I've decided that my main project for the next four years of my college career is going to be building a CNC machine. I've given it alot of thought and I've decided to go with EG for...

How rigid are they compared to full steel ones?

Awesome! I'll start reading the manual tomorrow.

I found a never completed gantry router a few days ago and I noticed something odd, the linear rails are made of aluminum with steel inserts.

Has anyone used these before or have any...

Hey Tom,

I think they have the manual, they have a filing cabinet where they store most manuals. I remembered reading that GCODE was a $500 upgrade for the Hurco, is that incorrect?

I will...

I am an intern/employee at my college's prototyping facilities.

I'm a freshmen and I just started a month ago and there is a Hurco VM1 sitting in the corner unused.

Noone knows how to use it...

Hey everyone,
I need a Tormach PCNC1100 Post processor for solidcam.

I've been looking online and it seems alot of people use a modified fanuc processor but I haven't found much more information....

I've been thinking about ganging tooling and I am trying decide how to best do it. My main worry is about the travel as the cross slide does not have alot of room and it would seem like I would have...

I plan on doing it on a hardinge hlv lathe so the machine is pretty rigid.

Did you just have problems with the rigidity of the machine or was the ball screw flexing.

I was thinking, so I was...

major diameter is .232"

20/21 threads in roughly 22mm

Should I just buy a different one, use mine, or is it worht it o make my own? It sounds like a fun project.


I have a question: I have...

Im getting rid of the compound slide for increased rigidyity, I would like to add more bolts in my replacement so that I can have more overlap between the stress cones, however the bolts seem to be...

That makes a ton of sense. Already got it out by hitting the side of the block with a malet and then fitting a wedge in the gap and hammering it in. Not my smartest move. The pins are bent. Hopefully...

I'm starting my planning to convert my lathe to CNC today. I'm starting by dissembling it but I'm running into problems.
I'm trying to take the z leadscrew off but I can't.

What is this little...

Those are interesting designs.

I'm slightly confused about the second one, is it a modification for a prebuilt table?

I like the first design, however I want something significantly more rigid...

I would like to build a fourth axis from scratch.

I have a few questions.

First: how do I do the drive system? I was thinking I would just use a timing belt drive system. Is a worm gear...

Warned away from the acroloc.

I will go with a DIY driver for my lathe to try it out and the Geckos for my mill.

Since I am trying to make a very small four axis capable mill I think I should...

Ok. I will stay away
