Re: [Emc-users] LiveCD update
Hi Alex, I'm about to use emc2 to drive my embroidery multihead machine. But, I'm not shure about speed. Embroidery machine runs at 400 rpm.That means Emc2 must generate up to 600 pulses in 75 miliseconds, at two independent paralell port lines, and with acceleration and decceleration phases, trapesoidal (or S-curve shape if possible). After this is 75 miliseconds pause for preparing next pulse generation. Question is: is this possible ?

It now features emc2.2.1 along with all ubuntu updates (up to last night). This is the encouraged method for new installs. It is not meant as a method for upgrades !! The necessary steps for upgrading emc2 are described in the wiki: Updating emc2: http://wiki.linuxcnc.org/cgi-bin/emcinfo.pl?UpdatingTo2.2 Updating configurations: http://wiki.linuxcnc.org/cgi-bin/emcinfo.pl?UPDATING If you don't have an internet connection on your PC, then simply downloading the latest emc2 package (found at: http://www.linuxcnc.org/emc2/dists/dapper/emc2.2/binary-i386/emc2_2.2.1_i386.deb ) on another computer, moving it over (via USB stick, CD, or whatever), and installing it (by clicking in the GUI, or by using sudo dpkg -i emc2_2.2.1_i386.dev at the command line) should be enough.

Re: [Emc-users] LiveCD update
Hi Miroslav, that's even less. I'd say it's realistic to expect about 25-30.000 pulses / second from emc2 without majour problems. Regarding trapezoidal profile, it does it properly if you set the right acceleration values. S-curve profiles haven't been implemented yet.
