Newest version software

[evan]

thought I should give an update.
Still without the use of the Bot ;-( Recieved a file from Frank @ Support but alas it didn't do the trick. Now I can't get it to connect on any Port
(and believe me any port in a storm would do) even tried another computer. I'm waiting to talk with Frank to see what my next option is...

Evan,

It is possible that you may have a ground loop between the bot and your computer.

Are you using two different power points?
Both grounds need to be well connected. With a meter test the voltage between the two grounds, you need to break the loop to do this so disconnect the USB from the control box. With both on ,you should be measuring as near to zero volts AC as possible from the back of the PC to the Control box surface.

Excercise a bit of caution doing this as you can get surprised. As I did discovering 80vac from the ground of a PC to ground of printer, I'll stick to caffeine for a buzz thanks.

I'm remodeling the house and left most of my eletrical tools at home. I'll go home at lunch and pick up my meter and check it out, in the mean time waiting to hear from Frank again. Grant e-mailed me last night suggesting to look at the Device Manager to see if the computer was recognizing the USB to Serial Bridge, which it is. Their going to walk me through a diagnostic this AM.

OK, I don't know how I did it but when I installed the new .exe file Frank sent me the first time I must have corrupted it. I unistalled all reinstalled, then reinstalled the new .exe and WA-LA
Everything seems to be running fine now.

Frank told me that alot of folks are having the same problem that I was with 3.4.8. They do have another upgrade in the works but it probably wont go on the Download site till Ver. 3.4.12 which wont be for a while. But they do have this "3.4.9" fix for those that need it, not a full down load just the Sb3.exe file.

Thank you Paco and Dick for your help.

More than often it's the shopbot.ini file that get corrupted... if EXE file(s) were to become corrupted from usage than computing would become something like nightmare... back about the shopbot.ini file, when odd trouble(s) happen, I regulary try to have SB3 make a new one to see if it's "corrupted".

I just updated my control software at the machine. I am not sure what the previous version was, but I updated to 3.4.1.

I was quite shocked at difference, the machine sounded completely different. Acted like it ran smoother too. I have still to download the latest version and get both the design and the control computers updated. I have dial-up at home, so I us DSL at work to get my latest updates. Soon I will have DSL... Soon...

Can anyone tell me why the difference in the results?

Improvments, fixes! Look at the read me file... as far as I know, ramping and look-ahead is regulary being improved... 3.4.8 is even better (than the previous releases) on the 3D (V carved) files...

Version 3.4.16 seems to run with less 'chatter' than previous versions. After running a number of ramping variable tests, the factory default settings produced cuts that were nearly the same as settings that really slowed things down. In other words, there was no practical difference.

The test that I ran was to cut a six-inch long 45-degree groove 1/4-inch deep using a 3/8-inch 2-flute compression cutter at a feed rate of 6-ips and a spindle speed of 15,000 RPM in MDF. The only parameter that I changed was the length of the ramp, which was increased by 0.4 inches for each test. The default 0.4 factory setting was nearly identical to the last test at 2.0. After spending some time with a magnifying glass, I finally realized the stupidity of searching for flaws. If it ain't visible to the naked eye, it just doesn't matter.

Running a series of circles showed much improvement from earlier versions. I did find that cutting the circles at 4-ips instead of 6-ips gave better results.

To summerize: Version 3.4.16, with factory settings produced the cleanest cuts of all the versions that I've run since getting the Alpha in July of 2004.
