[Emc-users] Blog Posting - Configuring EMC2 for Steppers

2008-04-29 Thread Andrew Ayre
I just posted a blog entry on how I configured EMC2 for my three stepper CNC machine. OK, it's the most basic configuration, and I picked a specific situation (200 steps per rev motors, 1/4 microstepping), but I hope it will be useful to someone else as a starting point. http://www.britishideas

ok, forgot my last message...I managed to get the rtapi module to load. I finally found the right spot to add the mcmodel=kernel option and emc gets past the rtapi loading. Then 'motmod' module gave me trouble. It said the following symbols are undefined: cos, sin, atan2, acos. I had to go back in

There are two drivers, one for the AX5214 and one for the Futurlec PCI8255 card. They are called hal_ax5214h and pci_8255, respectively. The pci_8255 driver has been included with EMC2 since 2.2.0, the ax5214 driver has been there since before the 2.0.0 release. For either card, you have to supp

Thank you Andy Ayre for such a great article on getting EMC2 and RTAI running on Ubuntu 7.10. It was invaluable in my attempts to get EMC2 + RTAI running on Ubuntu 8.04 Hardy.

Hello, I'm using emc 2.2.2 and can't seem to override limits. This makes it hard to realign the table manually if emc2 happens to quit oposite the normal *home* position. Is there a workaround until emc2's *override limits* button becomes functional? Thanks. Robert W. ---
