This machine is for sale in New York City. It's been working great for the last 6 years. I'm moving and can't take it with me.

I'm attaching pictures of some parts I've made recently and the...

Built this lathe around 2004. Made a bunch of parts on it. Never finished the enclosure so it sits as you see below. Looking for a new home. Someone mentioned the shaking of the machine in the...

It's been a long time and I've moved on to other projects. I'd like to sell this lathe or maybe part it out. It's currently in Queens, NY. More info to follow but PM me if you're interested.

I cant remember if I used +12V or +5V. My probe acts as a normally closed switch that opens with the probe tip is displaced.

Yes. It's working great. I can't imagine life without a probe. My only issue is the probe is quite long and I have limited z travel on my machine. I have a shorter probe tip and I could rework the...

My 340 was delivered two days ago. I have a bunch of documentation / manuals with it that I haven't looked through yet. Looks like you already have yours sorted but I'm happy to share with anyone...

I don't understand your last post. What is the Commander?

Thanks for the replies. I know I can make it work without wear offsets, it would just be much more convenient to have them.

I'm not looking for automatic wear adjustment. This is how I'm imagining using the wear offset: I have 100 parts to run. 1.000" OD +/- .002" I set up the tool offset and start turning the parts. ...

Sorry I wasn't more clear. A wear offset is like a tool offset but is used to accommodate wear on the tool (usually inserts). As the tool wears you can change the wear offset so your parts still...

Does linuxcnc have wear offsets? I tried searching but I couldn't find any recent news. I just bought a used lathe with a flaky control. I'm trying to decide if I want to try to repair or retrofit.

Great. I'm expecting the machine to be in my shop on Monday at which point I'll start my own thread. It has a couple electrical / control issues. I'm debating between retrofit or repair. Did you...

Hey Allen. Nice job. I was inspired by your youtube video so I went out and bought a very similar lathe. I don't have it in my shop yet but I'm hoping you can offer some guidance when the time...

I have scanned the wiring diagrams that came with my machine: http://www.flickr.com/photos/gothammachine/sets/72157628431509777/ If you want higher res PM me your email address and ill email them to...

Thanks for the definitive answer. Any thoughts on increasing spindle speed? Higher rpm motor with a vfd? Any idea what bearings are in there?

What kind of tolerances are you trying to hold? Routers are really designed to work with sheet goods. 4" tall parts are asking for a milling machine. 14x10 is not too big. If you only have 6" of...

Draft is the angle that allows the pattern to be removed from the sand to create the cavity for the liquid metal to be poured into.

I'll let...

Thanks for the reply. With a 1/2" wall thickness and no ribs my CAD software says its about 40 kilograms (88lbs). I have a lot on my plate right now but hope to get to this soon.

Hey Andrew,
Here is a potential project. I'm posting here so everyone can learn something. If you want to contact me privately please PM me. Its a cast lathe bed to carry linear ways and a self...

I'm still willing to host. We had one "meet" at assset's shop. It was just him and me. Weekends get harder for me to schedule as the weather gets nicer and the family wants to do things.

If...

Lots of progress.

I order a NMTB30 tool holder with at JT6 male taper from Penn tool (its a Bison tool holder). I receive it and rather than the taper starting immediately below the flange it...

Backlash compensation has its limits. If you want to get the most from your machine you should consider ballscrews.

Superbowl this weekend, cant do next weekend. 17th and 24th are possibilities. Anyone else interested?

Sure. When is good for you? Anyone else interested?

Ok. New plan. I can get a NMTB30 tool holder with a male jacobs taper. Then I'll cut a matching taper in the adapter plate using my lathe. I don't have a grinder on my lathe. I'm considering...

Frustrating day today. I went to put the blank tool holder in the spindle and the flange was too wide to fit inside the nut. I've heard of this when using import tool holders. I cut down the long...

I called a few places a while back with no interest in small jobs. I'm looking for a foundries that are seeking out that kind of work.

Same question but I'm in NYC. Looking for foundries to do 1-10 parts iron and aluminum depending on the project.

I received the toolholder blank. The ring that the locking nut uses to hold the tool in the spindle is about .1" too big. I'll need...

I think that is LINUXCNC's particular flavor of gcode. I've only used Mach3 and LINUXCNC so I can't speak to how it matches up with Fanuc or whatever the standard is.
