Well I got out to the shop and tried using the pyvcp DRO. I found a few problems. In my .hal file I referenced the wrong .xml. This should be fixed now. The .hal file uses the xor2 component, which is not in EMC 2.1.7. I changed the mill's Synaptic repositories and updated to 2.2 and the component now works. Then I found that the <scale> tag would visually function properly but the halpin tag would fail with a "pin 'pin_name' not found ... link failed". The only thing that worked in the long run was to switch to <spinbox>. Is there a known problem with <scale>? Apparently, "loadrt hal_ppmc extradac=0x00" is not enough to get the UPC working. As soon as I hit "addf ppmc.0.read fast" the PC would lock up. I had to unplug the computer to reboot. Can the UPC encoder counters and DAC be run only using HAL? Now that FERROR and MIN_FERROR settings have allowed me to start making chips, it's not that important for me to complete the DRO/VFD project, but the knowledge gained may come in handy in the future. For the price of a PCI parallel port, some junk box parts and HAL, someone could probably do allot with EMC before jumping into axis control. -- Kirk Wallace (California, USA http://www.wallacecompany.com/machine_shop/ Hardinge HNC lathe, Bridgeport mill conversion, doing XY now, Zubal lathe conversion pending) ------------------------------------------------------------------------- SF.Net email is sponsored by: Check out the new SourceForge.net Marketplace.
