I left my locks in and tighten them just tight enough to allow the free movement of the axes. When I'm facing a piece of metal, which I always do by jogging manually, I lock any axis that I won't be...

Thanks Teyber. This is good info - keep up the good work and the pictures as well.

If the belt pulley doesn't have a hub with set screws can't you just drill through the pulley and use a set...

Good job Teyber! I've been wanting to do that to mine but time is a problem. Have you tried milling aluminum with it? With say up to a .75 in. end mill. I do need the better speed for the smaller end...

Caleb what did you use to compress the files on your website? I get unkown compression method error.

Thanks,
Rick

Did you try it with the gib lock loose on it? On mine I notice that when I have the gib loose it reduces the problem tremendously. I found that the gib on these things are slightly mismatched to the...

I just trammed my mill and its not as close as I would like it either. I havent rechecked it yet after using it but I'll do that today. The problem I get is getting a consistent measurement whenever...

Great tip! Thanks.

Yeah I have magnets hold my wrenches on the front of the spindle head so I don't have to look for them lost in the swarf.

It is a standard grizzly x3 machine. The picture doesn't show the front is all. I finally finished the plate and can't wait to try it out. So many times I've needed a clamp on the y sides of the...

This is worth a better look. Won't work for me this time because I'm going to finish this today but I have lots to read up on. I just need to add a reversing relay to the mill. Thanks for the links...

Thanks Sam. I don't think I have the proper equipment for this yet but it's nice to know that EMC2 is such a great tool. My spindle has no auto speed control - wouldn't you need to know the exact...

Thanks Hoss. I remembered that when you first did it. Great job. What is the specs on the stepper? With all the torque I'm using to tap these holes I was worried about not having enough torque from...

Manual tapping sucks! Any alternatives out there?

Thanks,

Rick

Not really any need to check anything more in the binding area if you have access to and can turn the screws by hand if they turn freely with no power to the steppers you should be ok there. I saw in...

I have mine sety up with steppers. Yes I use BLC when I need to do drilling or squaring metal. I found it leaves a stepped surface when using ot on radius cutting.

The reason I ask these...

What do you have your acceleration set to in the motor tuning section? What version of Mach3 are you using?

If your power supply and driver are working correctly it really looks like your table...

Thanks for that Yarde URL Lee. These guys do sell pretty cheap. They also have a surplus section that has quite a bit of different of various metal sizes as well but I found out that some of the...

Man those look great! You wouldn't happen to have any drawings on that? I have to keep fighting with shims on my default setup.

Thanks,

Rick

Well I'm actually just worried about home position changing on me. The Y seems to wander for each time I set up the material or change the bit. I'm thinking I have the soft home set too close to the...

Well yesterday I found out one of the problems with the concentricity issue I mentioned above. I added homing switches to my mill and forgot to put the y gib lock screw back in and faced a piece of...

Hi Ray,

Have you done a project thread on your mill? I have a cousin interested in converting his knee mill and I told him I would see what I could find out about it. I have found bits and pieces...

Most of my machining is aluminum based and I don't have any issues with torque given the max spindle speed is 2k rpm. The only problem area about the mill for me IS the spindle speed. I need it 3x...

On my mill zero is at the top of the material to be cut. It goes into the negatives when cutting and positives when rapiding. I also stepped through your code in Mach3 and couldn't see any issues.
...

Thanks, Tom, for the in-depth explanation. I think you just saved me $100. I'll give this a shot.

Rick

I've been looking to increase my voltage on the z axis as cheap as I can and those power supplies look interesting but I have a question about them. How do you wire these in series? I'm familiar with...

Sorry, Mach3

Yes I was thinking it would be nice to have the table home towards me since this would also make it easier to set up for the next piece but I can also just leave the final resting place in the gcode....

I know that on mine with Mach3 I have it set to auto-zero once the switch has been hit and backs off of it. It resets machine zero. If I don't have auto-zero set on it the display reads about .005...

Please post some pictures. I would really like a quick solution to my cover problem. I'm sick of fighting with this piece of plastic.

Thanks,

Rick

I recently have found out (at least I think) a problem i have been fighting with over the past several months. I have a jig set up to machine parts in small quantities and every time I start a new...

Thanks Geof, you da man. I guess the white stuff is poly and the black is either acrylic or delrin I'm not quite sure yet. I burned my nose testing some actual delrin chips I had laying around and...
