LazyCam (Beta) / Re: New LazyCam has lots of problems
« on: December 04, 2006, 12:30:57 AM »
Art,
I downloaded the file you suggested. It says it is the same version.
The Optimise Drawing check box cannot be unchecked.
If I do not check the box "Relayer" and I press either Optimise or Autoclean, I get a blank work screen (scary).
If I then check the "Relayer" option, the two buttons do work (and the lost image recovers too), and they do seem to produce reasonable clean chaining results. If I do autoclean once, it finds 4 of the five outside edges (squeezes 5 layers down to 4 layers), If I click a second time, it finds all 5 (and squeezes out another layer).

I have three distinct DOC that I am trying to use, and a fourth for outside cut layer. The Autoclean only creates three DOC layers and I loose the fourth. I can, of course, create a new layer and sort out the critical items, but I believe I shouldn't have to. It would be nice to eliminate the layer that I use to keep track of the outside path. If the program can now find and separate them reliably, that will save time.

Obviously, the program cannot tell that I want each layer to translate to a specific DOC, but I suspect it should be wary of merging layers, because there is usually a good reason for using multiple layers.

I am at a loss as to who your target average EasyCam user is. The files I am trying to convert to G Code are basically flat AutoCAD 2.5D drawings. as far as I can tell, they are nothing fancy. I convert all the lines to actual tool paths in AutoCAD (a somewhat painful process). I haven't used any complex shapes, and nothing 3 dimensional, where X, Y, & Z are all changing at once. The image I sent you was of some simple clock parts. The parts have through holes, milled surfaces (two different depths), and outside cuts (thus 4 layers).

How come there is an option to "Load current Mach 3 file" if it isn't supposed to interpret G Code? It gives an error whenever I try it, so maybe you need to remove the option from the menu.

How do I toggle the climb mill mode ON and OFF for a given layer? I am finding that different materials like different cutting modes

I just tried a tool change and noticed that it does put in the M6 code but no tool number. Is that the way it is supposed to be?

Thanks.

LazyCam (Beta) / New LazyCam has lots of problems
« on: December 03, 2006, 04:53:15 PM »
Hi,
The new lazy cam is really badly broken. I have a file with 5 layers, and it merged all five layers into one (no matter what I tried to tell Autoclean to do or not do). Seems that Autoclean is permanently ON. Then it named 3 of the 5 layers with the same name.

Please let us control the layering. I use them to control DOC and Option select. The least you can do is ask if it is OK to tamper with the layers.

The top layer is usually my reference layer (non cutting) and I always turn it off. It now has everything stored in it. Bummer.

The three other layers weren't supposed to be empty, but they are now. All of the cuts will need to be sorted out again. (one of the cuts is very small and will be hard to select it to move it)

Up until now the dimension layer had been ignored, now it is proudly presented in the list even though it was empty in the first place.

Most interesting, the optimized routing is not following a chain as a single cut. It broke all of the chains, and cuts most segments (primitives) separately. It almost seems to be maximizing the movement of the tool without cutting.

Just clicked on "relayer" and it did some intersting sorting... got most of the outsides right, but grouped the insides somewhat randomly. It looks to be a better place to start my end of the sorting, I guess. (I want my layers back)

Origin is not automatically minimized.

Whatever you do, Do not press the "Optimise" button! It will erase all of your sorting work and leave you with an empty screen. Mega bummer! I get to start ALL over again.

Lazy cam needs to be able to pull in a G Code file from the disk. So I can do frequent saves while trying to get it right.

Note the three g code submissions; the first ....B file is from the old LC program (took only a minute to set up correctly) and the ....X2 file is from the new LC program. The second took much longer to get to this point and it is almost useless, because I can't find a way to make a chain as one uninterrupted cut, nor am I sure I have all of the layers sorted properly. The third is the DXF source.

The new program is now click intensive, far too many clicks to do a single task. Perhaps the list boxes should pop up open.  The data table was nice for this reason.

Guys, you were doing so good! What happened?

Just found multi select... nice.
"Set Layer Depth" command crashes the program. Please disable it or fix it, and the others that crash.
Enough complaining for now. Switching back to an older version.
Thanks.

General Mach Discussion / Re: slow stepping on power up

Hi,
I ran MSConfig and found 7 processes in the startup. I unchecked all but the Mach3 and rebooted. Mach3 ran normally, so one of other 6 programs was contributing to the problem. I enabled three that were relatively obvious as harmless (msn, wireless LAN, and touch screen serial driver), and all was well. Enabled Autocad, and again all good. Enabled LogMeIn, and again all good.

The bad boy was Skype. I don't know why I installed it in the first place, but now it is disabled, and all seems to be well.

I have not tried backing off on the video accelerator yet, I may try that some day, but that doesn't seem important at the moment.
 
Thanks.
Bill

Brian,
I ran the driver test several times and it always looks normal. It is mostly a straight line at 40us with a few spikes that don't deviate more than +/- 25us. The test runs for about a minute and indicates that it competed. The program does not seem to offer any other conclusion about the test.
Thanks.

I checked both profiles and both said "Mach3Mill". I expected this because I had coppied the desktop shortcut directly into startup.

I just ran a driver test and it was normal. I don't have anyway to do a driver test before I boot into the Mach3 program, and the driver test issues an error if I have Mach3 open when I try to run it. Once I exit Mach3, everything goes back to normal. It is consistant and does it every time.

I looked into the configuration while it was acting up, and the settings looked correct. I then observed the interrupt timing and that also looked normal. One interesting thing, when I shrank the window to get to the desktop, it shrank down slowly, taking several seconds to get down to the task bar. The buttons and the folder selections are running at full speed, and loading a G-code file seems to all go at normal speed. 

I suspect that something that Mach3 needs is starting after Mach3 is loaded and is bogging it down. I should set up a 30 second timer to delay its starting.

Thanks.

General Mach Discussion / slow stepping on power up

Hi,
I installed a new PC to run the CNC software, and on a whim, I have the, XP-home software auto load and run the Mach 3 program (ver 2.005). Each time I boot up the computer and clear the RESET, the motors run at an incredibly slow speed. I can hear every step as the motor starts to accelerate. I is running about 1% of normal speed. Everything else seems normal.  To fix, I stop/exit the program and restart from the desktop icon. The hard drive was formatted and loaded with XP-home, serial touch-screen driver, Mach3, AutoCAD, a couple freebie text converter packages, and precious little else (just enough to make it run).

Any ideas?
Thanks.

VB and the development of wizards / Re: turning an ellipse wizard needed

An ellipse is what you see when you slice through a cone at an angle. If you need equations try the wikipedia link.

It has everyhing you would ever want to know about an ellipse

Thanks.

Thanks everyone for all of the help.

It looks it is time to hit the books again and graduate from rank amateur to the next level in the field of CNC.

As I told Chaoticone, I have this very nice single button pendant (NO), and that it would be really nice to use it as a run/pause during setup. I currently have a touch screen and keyboard and my reaction time is terrible when using them. So I'm looking for a single hand control that may allow me to react faster to the situation at hand. I also need to use a better video layout to be more touch screen friendly. The default mill screen isn't bad, but some of the important features are on small buttons.

It seems that I have this incredible natural ability to break bits.   

This is one project in my life where I have developed a strong religion to wearing safety glasses and hearing protection. At the end of each day, I count my fingers and eyes, and after finding them all there, wonder how that happened.

Thanks.

Ran a small test run this evening and the 0.1uf capacitors seem to have helped. I could feel the head doing a lot of hard turns. The X axis relay was probably chattering. I am surprised that the digital debounce didn't handle it better.

Normally closed is the only safe way to go. I require it of all of my process controll customers.

If I use only one relay, can it also do a homing correctly?

The cube was my test run. It is made out of pine, one inch square, cut with a 3/32 bit, and is poorly centered. I need more practice. on alignment

One more question, is it possible to have a single push button do RUN/PAUSE? Hold it down for RUN, let go for PAUSE.
Thanks
Bill

Backlash is OFF. I can't see any advantage to using it. There is a little slop in the system (0.001) but it is not enough to worry about yet. Flexing is a bigger problem that backlash wont fix.
