I regret to inform you that there has not been any movement on this in a lot longer than a hot minute. I am suffering from limited time in the shop and the old cnc mill of mine was acting up and...

I know this is likely a dead thread... but how is the scale determined? It doesn't make any sense to me.the step count for the harmonic drive isn't 141.6666666 steps per revolution.

My 4th axis is...

I know this is long since dead.... but I did exactly as BroncoBill said. I milled the end of the casting and bolted up a weldment. I'm also using linear rails, so the whole level thing becomes...

Following.... I wanna use one foe a cnc lathe spindle motor. it is like 175vDC to earth...... it's crazy high voltage.

I have access to a surface grinder.... so why not?

Here is the journey to where I am right now

A family friend tacked and welded the bed extension together for me.

Ssssoooo... I've been busy.....https://www.cnczone.com/forums/attachment.php?attachmentid=466262&stc=1

I have purchased one of these Sewing machine servo motor setups from Amazon ...

Ok guys, updates. Sorry it has taken so long, my mill was down, nothing like chasing ghosts but your axis keep just not working in the middle of a production jobs... Anyway, this is a different...

Here ya go! I just started it up :)

This is my build log of my CNC lathe coming from a Harbor Freight Mini Metal Lathe. I have pretty much scrapped everything... I have followed come others here and decided to cut off the vee ways and...

Because I'm a goofball, and I'd like to put my tailstock back on. The tailstock is already gonna need a redesign because the carriage is so damn wide and as it stands now, it won't reach the tip of...

I am following suit as you did. I am double 1204 nutting the x axis. the preload will be adjusted via the accessible one towards the rear of the lathe. I am using 12mm rails however. If you look...

WOW! Not gonna lie.... that is much busier than I expected it to be...

I have been trying to look back and sneak a peek at the pictures, but unfortunately there aren't many to look at. How did you trim down the ball nut, carbide or a zip disc? What is moving along the x...

Ok.... SO I've been playing with my model in Solidworks. I'm planning in using a 1204/1205 screw for the cross slide..... HOW THE HELL DID YOU MAKE IT FIT!!!????!?!?! I can't figure out for the life...

Have you posted your drawbar and belt conversion anywhere?

3) I'm not sure I understand the question.[/QUOTE]

For my lathe, I was thinking about having the tailstock being able to be positioned. Give the tailstock the ability to move in and out under a...

Never mind to the question about the homing switch, I see that now. But that does pose another question.... How does that work with your bounding box that is the work envelope? If your tailstock...

So, I have 2 questions:
1) Where is your homing sensor for the carriage? Is it attached to your tailstock so it will never be able to crash?

2) Have you considered adding either a pneumatic or...

I love that someone is working on this! Does your program have any chance of seeing a g20/g21 functionality in the near future? I'm a teacher and I am wanting to use your program here at school for...

I didn't have your most recent version. Awesome. I am very excited to get this lathe up and running! Thanks for the updates!!

So you are going to eventually get to adding inches into your software (which is pretty sweet by the way). One other question that I have for you is this. I use Fusion360 for my CAM fork. that's what...

Any hope of adding the g20/g21 (Inch/Metric) functionality? That seems to really be the only thing missing here!

Hey, My biggest concern here is if I can't get it to do what I want, that is only $2000 down the tubes... Would it be better to build a CNC with the same envelope or buy a junk mill with decent bones...
