General Mach Discussion / Re: Different use of Mach3 (dispensing)

George,
What did you end up using for precisely dispensing the resin?

Great work, i love to see machines controlled by mach3 that are not lathes and mills.

Well, 200 is a fairly good amount, you could try increasing it 100 by 100 and see if it makes any improvement, if it doesnt, then drop it back to 200.

Id like to know too if the artcam post can be improved, a friend of mine has the same problem.

Greg,
THat did it!, It had the same name in my bios.
I also disabled my floppy because i dont have one installed. Although i dont think that made a huge improvement as the C1E enhanced...
Now the driver test is as flat as ive seen it, even at 100Khx, not that i am going to use it at that speed, but at 45Khz, my pulse rate only varied by 3 counts on average.

Thanks!!! a lot!!!

WEll...
First of all, i think plasma mode was intended just for plasma cutters. So i believe that setting should be off.
If you want precision you should stick to exact stop since there is no way to remove the corner rounding completely, even with high acceleration.
But as you say, exact stop is too slow, even with high accelerations. Specially, ive heard ARTCAM  outputs many tiny little segments in their posts, you could try increasing the lookahead lines, although i think you will still see little increase in performance.

Your machine looks rigid, but only you can be the judge of your machine handling such jerks.

Well the thing is, that when cutting with plasma, you need mach to run in Constant velocity, this comes with some tradeoffs, mainly being that the corners get rounded off as to keep the velocity constant.
The only thing to get this to be better is with higher accelerations, which sometimes machines cant handle much acceleration (machine starts to flex, vibrate or even destroy itself) or the motors cant deliver enough force to generate this accelerations.

If your machine can handle it, try increasing your accelerations.

General Mach Discussion / Driver Test Assumptions
« on: April 09, 2009, 02:52:00 PM »
Hello Guys!
I have a quick newbie question, its kind of newbie because it is a newbie for me.

This is the first time my Driver test graph is not a clean straight line.

Should we assume that if the driver test displays the SYSTEM EXCELLENT message in the pulse rating, that everything should be fine to work with mach?

The current PC I'm working on is displaying the system excellent but the graph shows spikes, even after some system optimization.

I'm attaching the test.

Thanks!!

Tangent Corner / Countersink drill collar
« on: March 26, 2009, 07:45:20 PM »
Hello Guys,

Im quite sure i saw somewhere, but i forgot where, that there were some collars that fit on a std drill, that on a single operation you can drill and just remove the burrs.

Im looking for something that would fit a 10mm drill, and prefferable be carbide or carbide tipped, since I will be using this on stainless.

Thanks
Fernando

What diameter cutter are you using?

Digital read outs... its the place where the axes positions are displayed. X, Y, Z, A, etc...

Good observation tweakie, I did understand you ;)

But i think by offsets he meant just drawing the offset in autocad, not using tool offsets within mach.
