esab ultrarex retro fit plasma / flame cutter

since upgrading emc to the new version the firmware that pncconf picks up for the card is different from what is was from the previous version and i cannot do any open loop servo tests in pnc and therefor carnt finish the config or even look at whats wrong


question is where is the firmware stored on the card or is it passed to the card during cnc startup ?

also the files from the old build that have the axis calibration window issuei have found a thred regarding spaces in the pid lines for the hal file but i see nothing wrong when ever i edit it i get start up errors

It is passed to the card during startup from the lib/firmware/hm2/5i20 folder.

If you have installed from scratch it is possible that you no longer have that folder.

sudo apt-get install hostmot2-firmware-all
might be required to get the latest set.

the firmware is uploaded on startup , it should be located at \libfirmware\hm2\5i20
and select an approprate bit file SV ( SERVO ) xx if this is a servo machine
svst8_4.bit is current so it should be available

i have tried that andy but it was up too date but i have noticed the firmware i used last time is there bit file and xml but they are not in the pnc window as a choice

i have found the correct one in pnc must have tired eyes

still canot get the open loop tests tho

pnc all sorted now turns out i'm stupid

any way things left making me think are the pid tuning but trial and error i know however i can only get my p value up to around 1.4 the rest of the settings are in the zero point range with the p any higher i get loads of oscillation anybody else only have low figures

next what do people think would be the best way of doing the hight control i.e. turn the output of of it then pause say 3.1 seconds (how long it take torch to go all the way down) then turn the output on for power source wait for the ok signal back then start motion, and on finish cutting command turn tourch up output on for say 3 seconds to clear plate and start move to next cut

would this be in some classic lader or gcode sub routine?

thanks john
