Hardinge Super slant 3 axis

This would be on the preview, think i am going to have to write some kins for a second tool.

here is a view of the two turrets if it helps

hum going to have to think about that. if it is only the preview then maybe disabling the preview would be the way to go. I can just ignore it, but i feel like there a danger in that. if it is to hard to put a second tool in the preview, could run a separate linuxcnc that just handles the second Z. this is how the machine worked originally with two funuc nc controllers. im guessing there no provision to load a second instance of the software on the one computer.

hum i will test that. this is the first lathe i have converted to linuxcnc, but would guess it is common to have a lathe with a tail stock. still getting the wiring and hardware sorted out, long way to go till i need to fix this. also going to look in to the hot wire sim think, i saw two tool points on that display.

Andy that worked great.

so to get it to work i had to turn on all 9axis otherwise i got and error,
so i would set up you small mill with xyz and all the standard stuff.
then mod the ini
in
[DISPLAY]
GEOMETRY = xyzu #this is if you want it to display the offset in the preview (thx andypugh)
then under
[TRAJ]
AXES = 7 #so mine = 9 because i wanted to use w not u uvw = xyz
COORDINATES = X Y Z U
then copy the whole [AXIS_0] section and paste it after the [AXIS_2] section then rename it [AXIS_6] mod all the info you need to in there
save and close that file, then open your .hal file if you used the pncconfig you may have to change you hm2_pci config line and add what you need
then mod the loadrt pid names=pid.x,pid.y,pid.z,pid.s add ,pid.u to then end mine was a few lines after the hm2_pci line
then a few more lines down there is a line addf pid.s.do-pid-calcs you need to add a new line there and put in "add pid.u.do-pid-calcs servo-thread"

now father down there should be a section that starts with
#***********************
# AXIS X
#***********************

Copy that whole section and past it after the Axis Z section
change the
# AXIS X to AXIS U
now there is a bunch of [AXIS_0] in this new section you have to change to [AXIS_6]
you also have to change the pid.x to pid.u, x- to u- and axis.0. to axis.6.
now im using pwmgen so yours maybe different but you will have to change all your outputs to the outputs your using for the long slide.
then mod your limit switch and your good to go.

if you get an error on start up you most likely missed one of the x or axis.0 in the hal file

hopes this helps let me know if you get stuck
