:) It's good to know that everyone starts somewhere near the bottom. I took a very short course in computer coding over 10 years ago so I understand the concepts (roughly) but that's about the extent...

Agreed! I'm always trying to find ways to 'trick' the program into doing things I need it to do. Did you teach yourself G-Code? I work for a sign company with a background in graphic design so I've...

Thanks for the input. Why would 1/2" holes be an issue? I use 1/2" bits for acrylic all the time but this is my first attempt using a bit that size in aluminum. As long as my speeds and feeds are...

I was wondering about the coating on the other bit being a problem. I think I'll order one of these and try it out. These panels will be painted after cutting so there will be some sanding that needs...

I'm using a Multicam 3000 series. Would you have a recommended rpm and plunge rate for such a bit?

This is the other bit I'm looking at. It's quite a bit cheaper. Thoughts?

I'm actually a woman :)... name is Angela. The panels I need to cut are 27"x76". I can fit two on a 4'x8' sheet of 1/4" aluminum. The panels are completely perforated so there are probably hundreds...

Thanks, Jim. I don't know any G-Code but I just looked up G81 and I understand what you're saying. My software does all the code for me so I just enter my depths, feeds and speeds and use the...

Thank you, Jim. That's very interesting... the slowest I'm used to running is around 18,000 for plastics and around 21,000 for aluminum. In my research I did find that drill bits should be run at...

Wow! 16 minutes is awesome. All we have are CNC routers. I'm not sure why my company keeps taking these jobs without bidding them to be subbed out to a plasma or waterjet cutter. It's extremely time...

I've got a job coming up where I need to make some perforated panels out of 1/4" aluminum. The perf holes are 1/2" diameter holes and I'm trying to figure out what sort of 1/2" bit I could use to...

Ian,

OK. I do see what you are saying about the tool path being rounded. Maybe I should have tried with out specifying an inlay gap. I wonder if that will make a difference for my fit. I find it...

Hello Ian,

Maybe I am a bit confused as well. The inlay FUNCTION is simply a check box in Router Offset Parameters, correct? Once the box is checked there is a space to type in the amount of gap...

Ian,

Thank you for the advice. Maybe I was not as clear as I should have been. I do know about the inlay gap function and have used it exclusively in the past. However, my new employer, and a...

Thanks Joe!

Yes, I know it depends on all sorts of variables including letter size and where the sign is intended to be placed and its purpose.

I believe I have solved the problem. Before I got...

Joe,
Thank you, but this is not my client to lose. I just program and oporate the router at my shop. What tolerance do you use on your push thru in order to avoid this problem? What is an acceptable...

I am doing some work for an extremely picky client. They want their push-thru to actually be push-flush (plastic is flush with aluminum face and has a flange) and they want a VERY tight fit. I am...

thank you :). Looks like I need to speed things up.

I am cutting a lot of push through for signs. I generally do an island fill for the flange using 3/16" bit to hog out and an 1/8" bit for the fine pass. Final depth is .6". Running three passes at 4...

I am trying to reach optimum feeds and speeds for cutting acrylic. I work for a sign shop and I think I am running my machine much to slow with most plastics. I need to maintain a decent edge finish...

Hello everyone!

I just started woking with EnRoute 5 and I can't seem to get an accurate reading on machine time. In EnRoute 4 I simply clicked on Machining, then Statistics, and it told me how...
