Re: I NEED HELP !!!!

I am sorry to inform you that your addiction is not curable. There is not much hope for you at all. The only solution that has worked even temporarily is for you to send all your tools to me. Trust me, you will feel much better, even if it is only for a short time. . . .

Re: excessive carve time

If you are using the Roughing RASTER technique then your bit is running at the Z plunge rate all the time. Anytime the software is cutting a 3D shape with it following the contours the Z feed rate is the controlling factor. The same is true for 3D finish. So, 15 IPM is really slow.

Re: Inconsistent toolpath

What you will eventually discover is that there is no inconsistency with the software in regards to pocketing. The inconsistencies reside in poorly drawn vectors. Nothing new about this, has been the case for as long as I have been working with CAD/CAM. Back in the day I dreaded getting CAD files fr...

Re: Compact metal plate engraver

CO2 lasers can cut metal but it requires an added gas [usually oxygen], a specialized cutting head and a lot of power. I am on a laser forum for Ruida controllers and out of hundreds of members I doubt that 5-6 have metal cutting capabilities. The reason is cost of course. I live and breath [and lo...

CO2 laser will not mark metals- there are sprays that will make nice black marks on many metals after lasering [with CO2]. You would likely use a Fiber laser for marking metals.
Well that is news to me! CO2 lasers can flat out cut metal, marking is just a matter of setting the power level.

Re: Running issue

Hi Scott, Thanks for the reply. I agree about it moving in X as my Zero was well left of start. I am only cutting 1mm at the moment but I can see how a lighter cut will make a difference, that will be my next try. As far as feeds and speeds go is there a tried and trusted method to use to work this...

Re: Single or double clamp for cnc spindle?

There is a simple rule for this sort of thing:

The length of engagement should be at least 1.5 X the diameter. That goes for all sorts of things, screws, dowels, spindle mounts, etc.

Re: Randy Inspired me

I like the hole!

Always laugh when I remember Andy Rooney (60 minutes guy). He liked wood working and made a really nice end table, three legs identical, one entirely different. Did it on purpose because he was bored making the other ones if I recall correctly.

Re: Alternative to Expensive Amana Bit

The angle of the bit has nothing to do with producing the effect geometrically speaking. What it does have to do with is surface clean up passes. The smaller the bit angle the less the image will change if a clean up cut is taken over the entire surface. A 90 degree bit will work as long as very lit...

Re: Anyone make a homemade Holddown that adjusts to tighten from the side?

Cam clamps can and do work. That said, you need to be careful with them. Two reasons: If you use a spiral flute upcut end mill and get too aggressive you can lift the material out of the clamps. This is especially true on smaller parts. Secondly, vibration can release the clamps unless you are near ...

Re: Thread milling

My slotters are large too but I run them at about 16K RPM. I cannot get any slower than that. The reason to undercut threads is to allow the lid to seat firmly and squarely when screwed down. The same thing can be done by relieving them on the lid side but that results in a thinner edge on the lid. ...

Re: Rotary modeling and toolpathing advice

Not quite sure why you want to turn it into an octagon? Me thinks you would be better off starting with a cylinder. If someone does not come up with a magic way of modeling this in VCarve maybe one of us could create an stl for you. You would need to give us the exact dimensions, not just estimates.

slowoodworker What problems are you having getting the two bits to close properly? What bits are you using to cut the threads? I still haven't looked at using slotting cutters to cut the threads so Ted would need to give more detail on that, I've now got a couple of bits for thread milling but have...

Here is your file set at 15 degrees. The change in material usage is not very significant. Capture.PNG This is what I was writing about above.
