Re: centerline cut direction

Ryan,

Thanks for the reply.
I'm not sure how designating a start point will force the machine to cut in a certain direction. I want the machine to make a conv. cut on the inside of a rectangular hole, not on the outside of the cut out piece. Am I missing something?

centerline cut direction

Hi,

We want to control the direction of cut for centerline cuts. The waste part usually has a better edge than the good part. I looked at the manual and I am thinking that "chaincompin/out" would allow control of direction (climb / conv). Is this the only method?

Re: CN wish list

One more thing, We do 95% of our cutting with the same settings on the "settings" screen. We would like to be able to save these as our "default" settings, so we could return to them without looking thru them all to see what needs to be changed back. Or be able to make "sett...

Re: CN wish list

Dave We've been doing some more experimenting with the ridge issue. So far the best edge results from a slower first pass climb cutting. We tried 400 ipm at 12000 rpm. Found out we could set the "% full feed for through cuts" to 200 which boosted second pass up to 800 ipm. Left a little fu...

Re: CN wish list

In the control nesting settings area you should see a "nesting parameters" area. Look for the nest direction box. In this box you can set the direction to X or Y. Click OK, then re-nest. Yeah, but I'm lazy and was hoping to get the same result without going back and forth to the settings ...

Re: ridge

Forrest, Talked to our operator again today. We get the same ridge whether we climb or conventional cut. Will, I gave some thought to the worn bearing idea. Our machine is about 4 years old. We keep it clean and check all rails for oil film regularly to make sure the auto oiler is working properly. ...

CN wish list

I would like to see a double pass setting that would allow the first pass to be over size (outside the line) or leave a skin or both. Then the second pass would shave the part to the right size, depth or both. We cut a lot of 2" thick solid wood, too. I would like to see a setting that would gi...

Re: Vacuum Gauge

Neville, We have a CS40. It has a 4" steel riser pipe bolted to the back of the gantry. It makes a 90* bend just before it changes to the plastic hose that loops under the table. We drilled and tapped 1/4"NPT and fitted a vac guage right at the elbow so it faces the operator. Sometimes the...

Re: ridge

Forrest, I'm not convinced it's bit deflection. The ridge is about 25-30 thou wide. If the bit's deflecting into the part on 1st pass by about 1/32", the part should be about 1/16" under-sized. This is not the case. The ridged, or bottom, face is about 1/16" over-sized. Single pass, c...

ridge

Hi We have a CS40 that's been running 40 hours a week. Runs like a champ. We've been having this annoying little problem for some time now and I remember it being covered here before, but I can't remember what the general consensus was. Here's the problem. The little ridge left on the bottom edge of...

Re: How sturdy is the Flycutter?

Okay, Time to flycut one side of wasteboard is 4 minutes, 11 seconds. Of course our table is only 4x8, so the same program would take longer on a 5x10. Damon, I'd be happy to share the program, but you'd have to modify it to use on your table. It makes a perimeter pass, then calls a label(?) and run...

Re: How sturdy is the Flycutter?

I didn't mean to imply my way was the best or only way Sorry if I sounded that way. It just kind of hit me like a slap: use the wasteboard once and throw it away ? And the 16 minutes, 19 seconds sounds like a long time. Now I'm a lot more curious. It sounds like the 3-4 times we flycut 1 wasteboard...

Re: How sturdy is the Flycutter?

Grady, The .25 MDF we've been getting here in Maryland is at least .030-.040 thicker at the edge of the sheet, so we always flycut a new sheet anyway. And the slightly roughed-up, fuzzy surface the flycutter leaves helps to keep small parts from moving around. The flycut program we wrote is pretty s...

Re: How sturdy is the Flycutter?

Looks to me like you ran the flycut program with the spindle off and it just bent when it hit the table. I remember being at the training class a few years ago when a long bit took a 90* bend on the 5-axis router in the demo room. They spent the rest of the day changing out the spindle. I can't imag...

Yes, Instead of going to the settings screen and choosing a nest direction of X, or Y, just change the nest button to two buttons, nest X, and nest Y. I always try both directions to see which gives better yield. It would be OK if I could just hit \"Enter\" to leave the settings screen. Or...
