Ok, I bought the Mach 3 software, and decided to try the circle wizard. Now, no matter what gcode I load, it starts with a circle, and just keeps going. then stalls out when the circle completes. What nifty little solution is there for this?
Thanks, John

Check the IJ mode is correct, ideally the code should set it for you but if you go to Config menu then General Config you will see the IJ mode, set it to the opposite of what it is now and see if that helps.

Hi John,
You'r not looking properly - it's there (just up, left of center - radio button selection - IJ Mode).
Tweakie.

Found the IJ button, toggled it, tho, still having the problem,
Thanks for the response...

I did some more experimenting and found that it does it even with new g-code files coming out of v-carve. I don't see how v-carve is the problem, as the problem only exists with this installation of Mach3. It goes back to the circles everytime I start it. This first started happening after I purchased the license. Then I tried running the circle wizard, and now everything seems to want to go to the circle wizard, even though my desired file appears on the screen, Mach 3 ignores it.
Thanks for any help, John

Are you using the right post processor for your machine?
-
It had been working fine, under the trial version. It has only been since I purchased the license that I have had this problem. I have uninstalled and re-installed, etc. This installation is not connected to my CNC, it is in a seperate building with another installation.
-
Attach your xml and also a sample of the code you are having problems with.
Hood
-
g-code file attached.
-
and xml please.
Hood
-
on the way, had a same name problem had to rename the file
-
Ok just loaded your xml and then your code and all looks fine to me, see screenshot.
What are you seeing?
Hood
-
BTW you do not have any axes set up in this profile, is it the xml from your machine?
Hood
-
no, this computer is in the house, not attached to the cnc router. I move files with flash drives because I run the machine with an older XP computer not attached to the internet or network.

screen shot farther along
-
What software program are you using to create the G-code file? Can you provide a screen shot of the "PROGRAM RUN" as well.
-
I just opened the txt file... you are using V-carve. I see a possible problem... your screen shot has a "G90" setting (screen shot upper right hand side Mill-->) in it. The text file you attached should set a G91 (see line #110). Aspire and V-carve need a G91 setting for JI mode and should override the Mach default setting of G90 when loading a txt file. Something is overriding the V-Carve G91 and switching back to G90. Make sure the JI in Mach conf menu is set for "Inc" not "Absolute".
What version of Mach 3 are you using?
-
Sorry... I mean a G91.1 not G91.
-
well this may not seem like Rocket science, but I went from the xml file for this profile, went back to the default xml file and everything is just fine. Since this computer isn't hooked up to the software, it doesn't matter. I'd be crazy if I had to reconfigure the machine.
-
The xml you attached worked fine here, the code is correct, it has the the G91.1 in it, as it should, so I do not know were your problem is, unless you attached a different xml from the one you are having issues with.

At this point it's safe to assume you have two different G-code files. One with a G90 command and the other with a G91.1 command. The screen shot clearly shows a G90 yet the xml file you posted has a G91.1 on line#110. If I read your posting correctly... to further compound the problem you are using two different computers running Mach 3. Like Hood I loaded the posted xml file on my machine and it's fine. No circles. I would do a complete clean Mach 3 reinstall on the cnc PC. Use Mach ver 062. Do not use ver .066 it had problems. Sometimes profiles can get corrupted and do strange things. Then only use V-Carve to generate the G-code files. I have Aspire on my windows 7 pro machine and xp machine running my cnc. I transfer files via a stick and never had a problem. I know from experience Aspire and V-Carve will do strange things with a G90 command.

The G90 is totally separate from G91.1.
G90 and G91 are distance mode, ie Abs and Inc distance mode
G90.1 and G91.1 are IJ mode ie Abs and Inc IJ mode.
Mach does not show the IJ mode in the string at the top but it does show the distance mode, think that is where your confusion is arising from.

Yes you are correct. I remembered something after my last posting I ran across quite awhile back before I started using Aspire. I purchased Newfangled Solutions Mill Wizard stand alone program and ran into the same problem with unwanted circles showing up. I believe there is some postings on this in the Mill Wizard section of this forum. Long story short... the program was so problematic and buggy I stopped using it and completely removed it from the pc.
