I did thread in 3/4 drill rod at 1500 RPM The pitch was 10 so they were some deep threads ;) I would say yes to the to slow breaking inserts because the steel will not shear the same at low speed.

John: I'll look into that.. Art www.artofcnc.ca

Art, Is it possible to have vertically aligned text on buttons? It would be nice in some instances to be able to have vertically aligned text if a person needed a tall skinny button to make the

Steve: Currently, running a G32 with no spindle feedback will stop the code. If you want to dry run, you need to have the index pulse coming in. I will change that soon, but it was only a test. It

Art - Just tried dry running a file but it's stopping on the line before a G32 even though "use spindle feedback" is turned off? Makes life a bit difficult for checking code. -- Steve Blackmore

Tom: Very close. I am simply trying to come to grips on the best avenue for it. For example, I could program in an index pulse when the X axis has moved a particular number of steps or is on a

Hi Todd: I am looking into it.. Art www.artofcnc.ca

Brian, Before I used the HSS bit, I tried carbide threading inserts and chipped two of them, the tiniest piece broke off the end. I had to use a magnifier to see it but I heard when it happened. In

Hello Art, Hopefully you can squeak it in... Excellon drill files are pretty basic; your hpgl import could likely be tweaked to allow for their format... BTW, I too think control is control, and

Wow I think I may be a bit out there but I run about 2000 RPM for a thread that small.. That is only about 325 FPM. That is SLOW for Carbide and you will get a better finish at that speed. We run

Hello Art, What is the status on the output pulses for laser digitizing? Thanks, Tom

To: Steve Blackmore Steve, a week or so ago I posted a message asking for any info on low cost PCI parallel port addin cards. You responded that the Lava card was good and only cost $16. I

A little bit slow maybe, for a 1/2"x20 UNF my old post processor would have done it at 500rpm, with 3 passes at 10 thou, one at 4 thou and one spring pass. (Total thread depth of 34thou) That's with

Maybe a few things made this less than a perfect test: The extrenely light cuts kept the machine going at a constant speed, within a couple RPM. Even with this light cut, there was some chatter,

Hi, Is there a way to make a line of the macro execute before starting the next line? It seems like the macros execute by type of call not the order the lines are entered. Todd

It is a reality that in order to develop something like Mach2, a certain amount of CAM functionallity must be included in order to appeal to the broadest segment of the user community. I have

Jerry: Your pictures have made me very happy. Its only a start, much more needs to be done, but you have proven the concept can work (Which I was very worried about, buffered pulse threading was a

I second that, or third, whatever. Keep it a controller only. Alan Trest "carlcnc" <carlcnc@y...> wrote:

Jerry, Threads look good. I'm glad someone is giving this a try. I'm in the process of converting an old atlas 6" to cnc and threading is one of the major jobs I want to use it for. Can I ask what
