eccentric turning

hi and thanks.

i think the bigest problem is to understand all the nets.
what must done to get motion.eoffest-active into true.

and scale the revs to deg. (*360?)
and what is when its 361 degree
. then it must 1 degree...


i hope andy can help.

do you use it on a lathe or a mill?
c axis as spindle?
or spindle as c axis?
or what?

i play on my table with a abz encoder resolution 500 (2000). wired to my parallelport.
the x and z axis are setup but not connected.

if i get movement on the x axis from the encoder i do the next step...

i hope someone help.. or can upload his working inis / hals.


could you upload yours?

thanks

i find out that my abz encoder had no working z signal... i done all on my desk... without the lathe.

 

Are you sure about that? The index pulse is generally very short and might be impossible to see if using the HAL probes (and will often not even show up in Halscope)

The way to test it is to set spindle.0.index-enable to 1, then rotate the spindle, and see if it resets to zero at the  index position. 

Use "sets" on the signal that is associated with your encoder index. In your case it looks like 

Will do it. 

For testing, I suggest opening an interactive HAL session. Start LinuxCNC and then open a terminal.

Will start an interactive HAL session ("exit to finish")

Then you can issue commands such as "show pin" to get a list of all the pins and their states (or "show pin *enable*" to see all the enable pins)

If the oeffset enable pin is unconnected then you can set it true with "setp" but if it is connected to a signal then you would need to use "sets" on the signal instead.

Other helpful things to type:
loadusr halmeter (opens a halmeter, repeat the command for more halmeters)
loadusr halscope (open the halscope)
delsig {signal_name} (deletes a signal, and unlinks the pins associates with that signal)

index works... but it reset not the count...

Hello, I'm sending you what I've done (it's only a draft). I've managed to open it for the moment, I can trigger the VDF spindle relay, but I still can't vary the speed; finally, I can't make the POM (error message: error followed by joint 0-1)
For the C axis, it's good for a spindle of turn ,I also have the index, A and B.

motion.eoffset-active what set it to true???


must i load a gcode?

i was thinking if the liuxcnc machine is on and i send over mdi m3 s50 i can get the eoffset work..

do you know this video ?

yes but i need a file (ngc) loaded?

I think it uses the one (circles.ngc) provided with the demo
I enclose a g code (test piston axis c I do not know if the offset works on it) and a g33.1/g76

ok my spindle.index.enable works with g76 or g33.1

the signal is ok. (new abz encoder).

but!


motion.eoffset-active is false,every time.

thats the problem.

if i send via terminal
halcmd setp motion.eoffset-active 1
i get pin ... not writable
with halcmd sets ... i get motion.... not found.

same with xo.active...
