Emc2 is set to g64 by default - constant velocity cutting corners
put g61 in the g code to stop -
www.mesanet.com (5I25 to 7I76)board i just got running (on Linuxcnc pre-apha-2.5)
i wanted to test the maximum speed of a step motor RPM Mesa Vs a Parallel port.
with the same voltage to the drive 24Vdc and 4 micro step for both I was able to get 1200 RPM at the same Acc. Step Pulse where set to 17000 Hz
I could also set 128 micro steps (25600 P/rev) only possible on the mesa card to get 400 000 Hz 937 rpm .
the best improvement was running the drive card a 36Vdc it went from 1200 to 1800 Rpm (150%) before skipping. settings where 4 micro steps and running from the parallel port
Here's what I've done to get 5i25 configured.
Install the latest beta version of EMC2.www.linuxcnc.org/index.php/english/compo...catid=9&id=15385
Install glade. www.linuxcnc.org/docs/2.5/html/gui/gladevcp.html
Download the firmware for 5i25.www.linuxcnc.org/index.php/english/compo...9&id=14940#14940
Download the xml file to desktop.www.linuxcnc.org/index.php/english/compo...0&start=24#15721
Create the 5i25 folder in /lib/firmware/ and copy the 7i76x2.xml to the new 5i25 folder
In terminal (ctrl-alt-t to open terminal)
sudo mkdir /lib/firmware/5i25
mv ~/Desktop/7i76x2.xml /lib/firmware/5i25/
Now pncconf allows selection of the 5i25 and 7i76 configuration.
Now the firmware is just sitting on my desktop is that all it needs? Or is the XML file I copied taking care of it?
My machine is not ready so I'm not doing much beyond this point. Lots of stuff to set up in there.
