Re: [Emc-users] EMC Fest

I'm at the hotel now, which is the only reason I can post this :) I don't know whether we'll have access tomorrow, so commits and IRC participation may be spotty. - Steve Hey you guys on the web-cam at Galesburg it's time to wake up - 17:55 UTC on 20th here at present - you need to work up an appetite for the BBQg John Prentice - Check out the new SourceForge.net Marketplace.

[Emc-users] Sheetcam
HI Trying to intsall Sheetcam TNG onto a fresh install of ubuntu 8.04. When I double click on .deb file it says the package might be corrupted or you are not allowed to open the file. I have downloaded and changed permission several times but no luck. Is there a solution Thanks Aaron -- Powered by Outblaze - Check out the new SourceForge.net Marketplace.

[Emc-users] Rookie help
I have EMC2 installed on an old Compaq iPaq desktop running Ubuntu 6.06 from the EMC2 install CD, driving a HobbyCNC controller and gantry with Kirk lead screws. When I use the sample stepper_inch config it works, but I need to tweak the configuration some to change the stepping (thread pitch, etc) but when I try to generate my own using the config tool in Axis, it just doesn't work. Suggestions? I figure this is probably something dumb I am doing, and I am willing to RTFM, I just need some direction. With the sample config, it is jogging back and forth OK, but it is not set for the right threads per inch for the lead screws. Once I get this working, next comes home and limit switches and a hardware emergency switch. The latency test runs, but if I do try to use the computer, sometimes the numbers go out of sight. 'Normally' it runs about 15000. When it goes 'crazy' It reads over a million. My 500MHz celeron may be to slow, but it is what I am playing with for now. Thanks. ...

Re: [Emc-users] SheetCam TNG V0.0.24 for Linux released
Hi Eric, I think I have found a problem with the sheetcamlibs package. Try downloading and installing the sheetcamlibs package again. If you still get the error, open a terminal and enter the following: sudo dpkg --force-remove-reinstreq sheetcamlibs You will probably have to enter your password. Hopefully that should force dpkg to delete the package. Sorry about that, Les Eric H. Johnson wrote: Les, Sorry to report, but loading sheetcam seems to have severely affected packaging functions (apt-get, synaptic, etc). Both the packages sheetcamlibs and sheetcam installed with errors, but sheetcam itself seems to be working. The problem is, synaptic, apt-get, etc. now do not. I am running a fresh install of Ubuntu 6.06 workstation. The only other application installed since the install of the OS was EMC. If I run synaptic, or apt-get, I continually get the error E: The package sheetcamlibs needs to be reinstalled, but I cannot find an archive for it. It then prevents the installing, removing etc. of any other packages. Synaptic further gives an error of E: Internal error opening cache(1). Please report. Thereafter synaptic lists no packages and in the status bar shows: 0 packages listed, -1 installed, 0 broken. I have also been equally unsuccessful in removing sheetcamlibs and sheetcam, which again fail on the same message. Any advice appreciated. Regards, Eric I have just uploaded the Linux version of 0.0.24 to www.sheetcam.com. This release now comes as a Debian package (.deb). This covers all of the Debian derivatives such as Ubuntu, Knoppix etc. If you can't use .debs then let me know and I'll see what I can sort out. I do intend to support RPMs in the near future. In many distros, simply clicking on the package in your browser will install it. The Linux version comes as two packages, the libraries and the application files. The libraries (sheetcamlibs-2.8.7.deb) need to be installed first. Once they are installed you should not have to install them again for quite a while. The application, SheetCamTNG-0.0.24.deb will change with every release. If you already have the Autopackage version installed, here is how to uninstall it: Open a terminal. In Ubunto it is in Applications-Accessories-Terminal. Enter the following: package remove SheetCamTNG package remove wxlualibs package remove wxgtk If you want to remove Autopackage itself then enter: package remove autopackage package remove autopackage The first time removes the graphical front end, the second time removes Autopackage itself. - Check out the new SourceForge.net Marketplace.

Re: [Emc-users] Rookie help
Hi Jack. What version of emc2 are you using? There was some quirks with stepconf on earlier versions-make sure you have the latest version. The latency test is not really to see how slow/fast your computer is, it is to see how late it is on scheduled tasks. Sounds like your computer can be really late. You need to fix this before doing any serious work as it could cause missed steps which will ruin your work.
