The belts and pullies sit about 1" below the cover so the drawbar does not interfere. I have latches on the side of the lid to make sure it stays shut when using the power drawbar, but I can unlock...

I'll agree with that servo, seems to work fine so I will leave it until it malfunctions, or I am bored and feel like making something, which happens to be all the time :)

I never touched a mill...

Wow those are nice looking pieces. I am sure I could think of a way to keep the drawbar locked from going up but it seems to work fine so far, so if it becomes an issue I will draw up some plans to...

Just finished mounting it to the machine and gave it a test run. It works great, the only thing that I may change would be to have a stronger air cylinder but it works fine with this one.

Also my...

Exhaust valves are one of the items I am waiting to arrive. At first I didnt think about it but then I realized that because some of the check valves that I am using the cylinder would expand but...

Here is a picture of the mill it is going on and also a picture of the air valves.

The socket is on there temporarily, I need to get an impact socket still. As far as valving the cylinder will go first and then the motor will spin. I have 2 mushroom button type valves for the air...

I purchased the pillow block bearings and cylinder holder but machined everything else. It was actually the first time I have ever used a vise to hold parts, so I was just experimenting a little. It...

After several months of using my first mill, I decided that tool changes are taking way to long, so I decided a power drawbar should speed things up a little. Here is my own version of the power...

I dont have a bridgeport, I have a chinese clone, but I am in the same situation. If your machine is R8 spindle taper like mine, I found probably the 2 best options.

If you care about fixed tool...

I am new to this as well, but I found an easy way of holding down the parts. My setup works great for milling aluminum plate, but may not be rigid enough to take realy deep cuts.

First I buy a...

Those are both the Sieg X3 mill. Grizzly is showing the newer version with the bigger table, while the HF is showing the older version. I do believe that HF is selling the new version but just has...

No I kept the stock leadscrews. I dont have enough money to convert the whole thing to ballscrews yet, but maybe later.

here is the first part I have ever cnc machined. This is the logo for the company I just started. It was done on some 6061 aluminum scrap.

I have not deburred or done anything to it, this is how...

I just bought a $350 dell special for the computer. It is running a celeron processor but I have no idea what motherboard is in it. I got the steppers, drivers from www.homeshopcnc.com. He also got...

The fit and finish is pretty good and probably as good as it is going to get with a $2000 mill. I have never owned or used a mill before so I really have nothing to compare it to in terms of quality....

I finally finished converting my grizzly G3102 vertical mill this last weekend. It took me about 1 week to design and build the conversion once I had all the parts. This is my first milling machine...

Ok so it may work then, if all else fails I can put spring under the knee and try that or maybe a gas strut rated at 100lbs or so.

I have a 1200oz/in stepper from homeshopcnc.com and was curious what kind of weight this stepper could lift with a 8tpi lead screw?

I have a small knee mill from grizzly and I am converting the...

DO you have any pictures? I would like to see how you set it up.

Thats what I was thinking to, so I will probably make something like the one from www.cncfusion.com and mount the stepper in the lower backside of the column.

I dont have the 5v PS ground connected directly to the geckos, it is connected to the ground on the breakout board which is pins 18-25. The only dedicated ground wire attached to the geckos is from...

I am planning on converting the Sieg X3 to cnc but I have a question. The primary use of this machine is 2.5D milling, not full 3D milling.

My question is, how bad of an idea would it be to mount...

Jimini- do you have a powered breakout board in your system? Whats the voltage change on the direction pin when you jog around? Also how is yours wired?

I have my main 65v PS which powers the...

Ive heard different opinions on this but since it is an optoisolated circuit and the ground of the 5v PS is connected to the ground of the PC PS and the motors are set to active low it should work.
...

I checked the voltages on the direction pins on the breakout board and at the plug entering the breakout board. The plug itself would go from 0-3.4 which confirmed to me that mach3 is setup correctly...

On my 5v power supply I have a +5v and ground going to the breakout board to power it up. I then have 3 +5v wires going to the commons on my geckos. The step and direction pins have +5v comming out...

I have mach3 (demo) running three gecko 202 drivers powering 2 640oz and 1 1200oz steppers. Mach3 is loaded onto a new dell running a celeron D processor. I have a belkin data cable running from the...

so what you are saying is that it should be opposite then because the table is moving instead of the spindle. (i.e push right arrow, table moves left so that if the origin is in the lower left corner...

I plan on purchasing the X3 in a week or so and I have some basic questions after converted to cnc and powered with mach 2 or 3. When jogging the table around and I press the right arrow, do you want...
