kstrauss, Thanks for the reply. I had read that section of the Linux CNC documentation and didn't see any reference to the units for the P parameter. They do have an example "G64 P0.015 (set path...

I've decided to take the plunge and switch my Series II 1100 over to PathPilot. The upgrade process went smoothly and I haven't had any issues getting everything up and running. What I'm struggling...

Thanks for the info everyone. The M6 screws I picked up were a success. I'm planning on mounting a bracket under there for some accessories. Anyone know why there is a big square hole in the head...

I have a PCNC1100 Series 2 and I want to attach a bracket under the head. I'd rather avoid drilling and tapping and luckily there are four threaded holes in the head casting just behind the spindle....

You might want to try Phenolic copper clad boards instead of epoxy fiberglass. It can be a bit harder to find and it's not quite as strong but it usually uses a paper filler instead of fiberglass so...

You will not find a hand held router for metal because the cutting forces involved make it totally impractical. With that said since you are building this yourself you do have several options. In the...

Can you post an image or a link so we can see the machine? Your description of the chuck falling off was shocking. A true milling chuck shouldn't fall off even with a crash that damages the rest of...

I forgot to mention that epoxy granite seems to be an option that many consider promising but I've only seen a few try.

Have you seen this site. He does his test cuts in aluminum but the mill was designed from the ground up to be an improvement over many of the retro fits that you see here.

I have a large benchtop CNC mill and I need to profile long narrow part out of a 3" x 10" bar of 3/4" 1018 steel. I'm planning on predrilling 40 to 60 holes around the perimeter and milling out the...

Just my .02 cents but from the shape of the part you might as well be cutting a tuning fork. The right size of the stock is a rigid setup but everything from the center to the left is unsupported....

Hi Andrew,

+-0.25mm accuracy and the ability to cut aluminum are going to be almost universal and a 10cm work envelope is fairly small. You gave us some good information but we also need to know...

Thanks for the info, I hadn't considered that an arc at a fixed IPM is still constant acceleration since is direction vector is constantly changing. That's another complication to add to my list of...

Does this update also increase the maximum milling feed rate (G01)? Everyone has been mentioning the rapid feed rate (G00) went to 90ipm but I'm assuming G01 might still be capped at either 56 or 60....

My guess is that you don't have an issue w/ the squareness of the mill or the code but something is slipping a bit after each Z rapid and you are seeing the cumulative effect of this after hundreds...

Since you mentioned that you recently replaced the computer it's possible that the issue is really with the software and the crunchy sounds are just a side effect of the steppers or other components...

Which grade of Aluminum are you trying to machine they vary quite a bit. I only have 1.5 hp and a 4" precision grinding vise and my only issues have been the part coming out of the vice, re-cutting...

The short answer is "Yes". There are countless software packages available to automate the various of software exists to automate the various steps required to produce a product. What you weren't...

I have the upgraded primary spindle, and I've tried using some 2mm PCB at 5,000 rpm on 6061 and haven't had much luck. They tend to break at the top of the flutes after about 20 minutes of cutting. I...

The R-8 and MT tapers that are commonly found on small mills have a number of limitations and were not designed for automatic tool changes. If you are looking for something that was designed for tool...

Thanks for the info Gary that was just what I needed. I've been confused as to why commercial thread mills (single tooth) were often only listed for a single thread size and reading through this...

I have a tooling plate to make that will have hundreds of 1/4-20 holes and a thread mill is the perfect solution but they have always been too expensive. Would you mind posting some more detail on...

Based on your photos I'm assuming that you making one slotting pass and then looking the results. I consider slotting a roughing operation and would consider metal removal rate over the appearance....

My local supplier only stocks structural shapes for construction and doesn't have anything in P&O. I've tried doing it myself w/ vinegar and it's slow, it's a pain to grind off, and when your done it...

I have a small mill and sometimes I need something stronger than aluminum that is easy to machine, 80% machinability or better. It seems that there are a several good choices for lathe work but if...

Are your running dry, flood, or mist? What was the width of the cut: 100% (slotting) or 50%, 30% ,25%, etc (profiling)?

I can understand where you are coming from. Many who are new to this start out wanting a router because the few inches of travel on a mill are so limiting. The two are similar but a router and mill...

From what I've heard slowing down isn't good for TiALN. It's performance doesn't kick in till the chips get really hot. With such high sfms' they really spray everywhere. I was just looking for some...

All my projects have been in plastic and 6061 and I don't have flood cooling yet but there are two brackets that I've been wanting to cut out of some A36 that I have laying around. Since that tool is...

I re-read your first post and had forgotten that you had a manual mill. Understanding manual milling is a big bonus that I didn't have when I jumped into it but CNC is very unforgiving. Tool life and...
