Joe, The company is local (within 30miles). I am there a few times a week in meetings and working closely with them on these projects. There is no rush to invest in the new equipment but it is nice...

Jiten, Thank you for the suggestions. This is the type of machine I am looking for. Now to get pricing and see if it's a good investment or not. Thanks again, Wil

Joe, Die cutting has not been working. We prototyped on the laser then they moved to die cutting for small production runs and it has been a complete failure. The inner details do not allow die...

Jiten, I can't really say what they are due to NDA's. Basic premiss is a 4" x 8" "card" with details cut into the card. The material is still in question. We have made this design in over 40...

I have been doing a lot of prototype paper cutting for a company. Now they are looking into a full production run of the parts. I was given the chance to quote on the production run but it is out of...

One thing I do is run double stick tape wrapped on the rotary wheels. Works better than the rubber and saves all the cleaning problems.

Or you can find silicone orings to replace the rubber ones....

That is the initial cost plus there is a large maintenance fee each year for updates.

Apsire is a good product for the money. Check out ArtCAM and it's price. It will make Apsire look much more appealing. :) Wil

I have ArtCAM and it will output grayscale that work fine in my laser. I am not sure if Express offers the same output. Since it's a trial I would check it out. Good Luck, Wil

Have you ever thought about having it powder coated? Lately I have been having steel powder coated over paint. The overall cost/ time is less and the finish is superior. I did some shelving brackets...

Easiest thing to do is fire the customer. It's usually not worth the hassle to wait for your money. I have fired a few customers in the past. Actually got rid of one last week. They didn't want to...

Good idea. I will try it tonight. Thanks. Wil

I need some ideas for a substrate. I am trying to cut acrylic tubing to a length and have a nice edge on it. This is not a problem. The tubing cuts fine with a rotary. Problem I have ti stopping the...

I have stuff waterjet cut all the time. For an 18" diameter it will probably run $12-18 each. You have to figure the machine consumes approximately $.3 per minute of garnet. Most of the waterjet guys...

The parts turned out nice. I prefer sandblasted over laser. That said most people don;t know the difference. Most customers are happy with lasered glass. One is because of cost, two they don't know...

A lot of my customers come to me because of the quick turn around. I offer overnight prototyping service for many of them. After prototyping I get to play middle man and out source the final...

1. I have always worked full time. My day job is a 5 axis programmer and manager at a mold shop. Laser and CNC work are my side business. The company I work for know what I do and does not care. They...

Thanks for the recommendations. I will tell them no then.

Vinyl/ Buna-N Foam. Has anyone cut this? Itis Mcmaster # 1833T47.

I have a customer that wants me to cut 4 sheets of it. Easy quick job. I want to make sure on the toxicity of it first.

I think this would be a good opportunity for the kids. At my daughters Junior High School they have laser and CNC in shop class. Her school is a public school. The kids seem to enjoy making things on...

Jim,

Thanks for the compliment. My full time job is managing and programming for a mold shop. I work with 3 and 5 axis machines everyday. :)

Michael,

You did a good job on the engraving....

I think the problem you will get is the if you are using a router for a spindle you will never get a proper chipload on the cutter.

Formulas.

Chip Load = IPM/(RPM* # of Flute)
IPM = RPM * # of...

You can use brass or copper for this. Much easier to work with and will heat better than steel. Best thing would be find someone with a cnc router and barter with them. Machining a stamp wouldn't...

I have though about adding one in for fire suppression. I don't think it would be that hard to rig up a detector attached to a solenoid and a CO2 tank. At work we have suppression systems on the EDM...

I use these discs from 3M for fine detail work.
