[Emc-developers] EtherCat / Analogue command combo

2016-09-23 Thread petr ruzicka 
Good Day 
It's nice to be back in the forum and see that people are still hammering out 
the bugs.. 
Here is a tricky one.. Is it possible to have Ethercat control for axis 
(3-5axis )  and old tyle +-10VDC for the spindle? 
I'm asking because made a bubu and ordered ethercat servopacks , however the 
main spindle is Fanuc original and trying to keep it that way so save some..?! 
Any ideas are welcome.

Re: [Emc-developers] Adding G84/G74 floating tapping cycles

2016-09-23 Thread tero.kaarl...@eka-sorvaus.fi 
Hi,

   It seems I was wrong. DISABLE_SPEED_OVERRIDE and DISABLE_FEED_HOLD do work. 
Using halmeter for pin motion.spindle-speed-out confirmed correct behaviour. 
Also Feed_hold_disable works but it was not what I was looking for. I was 
hoping to disable halui.program.pause during G84 cycle. How should I implement 
that?  Also G74 and G84 are now in same function "int 
Interp::convert_cycle_g74_g84" because despite rotation directions behaviour is 
same. Is this good way to do this or should I separate both to own functions 
for clarity?

Aihe : Re: [Emc-developers] Adding G84/G74 floating tapping cycles

Hi,

   As I mentioned before plan is to use Michaels code from here
   http://git.mah.priv.at/gitweb/emc2-dev.git/shortlog/refs/heads/g84-dev
   I just need to get these 4 year old patches to work with current
   master. Patches from Canon: add optional wait_for_atspeed parameter
   to START... to top. 1. problem was solved by adding this
   introduction to top of file static const char* plane_name(CANON_PLANE p);  
   
   2. Problem was that when only speed is
   changed what should I pass to motion.wait_for_at_speed. But I solved
   it by passing same state than it was before since it is not needed
   to change this one if speed only changes this needs changing only
   when spindle direction changes or when spindle stops. 

   But now I have a problem with Adding disable_feed_override() 
disable_speed_override
   and disable_feed_hold() during tapping(from r-level to r-level)
   disable_feed_override works like it should but disable_speed_override()
   and disable_feed_hold() seem to do nothing. These are needed to
   avoid broken taps if user has set feeds/speeds to something else
   than 100% before tapping starts(or during tapping). Okumas tend to
   disable overrides during tapping cycles. Only way to stop tapping
   during cycle is E-stop.
