I have Homing working well on my ORAC now and was attempting (unsuccessfully) to set up soft limits today.
Searches show a range of posts from "soft limits don't work at all in Turn" to "X works but not Z" to "Z works but not X" to "it's on the list to be fixed" to "it works great."
I seem to have trouble setting up anything new so it may just be me but am I wasting my time trying to make it worK?
-
i've set softlimits on machturn, and on an orac.
-
They were fixed a while back, have them set on the big lathe and they are fine but its an older version of Mach (057 i think) I use so may be broken in the latest. Wouldnt recommend 066 for a lathe anyway as there is at least one issue regards wear offsets in that and the Dev version and I also had some other weird things happen. Seems fine on Mill but Turn I would avoid the lockdown and Dev versions. Brian was told but not likely to get sorted as nothing ever does get sorted in Turn.

Thanks, I'm using .022 for the moment because I've been shy about updating and unknown things suddenly going tits up. I guess it's time I should try a later version and see what happens. Is it difficult to revert back to an older version if things go bonkers?
-
i use Version R3.043.022
-
That may be too old, think you will have to go about 056 or 057 or there abouts.

Yep, I'm a Luddite idjit. I just read the changelog and softlimits weren't fixed 'til last year sometime. .022 is 2009 I think. I'm off now to try a less ancient version. If ya'll see a huge explosion in west Tenneessee on the 10:00 news, raise a glass in my memory willya? ;D
-
what's improved from Version R3.043.022 to the current 066.

For me the biggie was the tool DRO the Tool description and a few other little things.

just going through the changelog.

changelog probably doesnt mention the things I mentioned but maybe?

Sniff, sniff...it don't get any better'n this. (Wiping the tears of joys away.)
I successfully installed .062 and all my previous setups still work! I then set up the soft limits and they work great. I like the little musical sounds the steppers make as they ramp down to a perfect stop on the dot instead of the dreaded mechanical knashing noises of a crash. Very, very cool!
I know yer not a drinkin' man Robin but I'm gonna pour a couple fingers of Drumguish and point my glass towards Scotland in your honor. It is, after all, Saturday night!:)

The Changelog doesn't have any reference to .066 at all at the moment; .062 is the last one mentioned.
-
i'm still wondering what your problem was, as i can get the soft limits to work on 022 without a problem.
-
I don't have a clue a/t other than the fact that my inexperience may have kept me from seeing some error in the setup in .022 that the later version was more tolerant of??
The changelog says "softlimits for turn fixed" in .057 so I took their word for it and updated. Maybe it works OK on some but not all setups in .022 and was robustly fixed later??
Also, there were several driver updates for threading mentioned after .022 so I was glad to go ahead & get that out of the way as I've yet to try threading. Gettin' close though!

Angeltech are you in Rad mode?
Hood
-
no, diameter mode.
-
Strange then as it was broken on X for Dia mode if I recall.
I never used soft limits as my lathe is big and only very rarely get anywhere near the end of axis but I do remember testing it out for Russ and reporting issues to Brian and eventually after about 2 years he decided to look at it ;)

it is odd, as it's not just on one lathe. i've converted quite a few, oracs, miracs, easiturns, boxford 160, boxford 125, starturn 4, starturn 5, harrison m300, boxford 240.
-
I will throw 022 on the lathe when I get to the workshop later on, if I remember, and see what happens but maybe its just something you do differently in the way you set machine coords and offsets that it works for you.

Just tried 043.022 and softlimits do work fine.
Have just remembered what the 057 version fixed, it was a message would pop up on screen saying programme would be out with softlimits do you want to continue. This was an erroneous message and 057 fixed it so that message would only pop up if it were to be the case that the programme extents were truly out with the soft limits.
What version the actual softlimits were fixed in I cant remember :(

The more I think about it, I'm pretty sure I had something wrong in the min/max locations or +/- setup. It was all a big blur yesterday trying this & that, error messages, etc. Maybe the time it took me to update Mach allowed some scrambled neurons in my brain to re-connect and help to set it up properly. ::)
I'm just happy it works now. I also saved a copy of the ORAC .xml and a screen print of the setup page in a safe place in case I screw it up later.
Man, I'm really glad you guys are here! ;D
-
i hate working out the softlimit values, it seems to defy logic.
-
The way I set softlimits in turn is home the machine and look at machine coords, I then jog the axis to the limits at one end and note the machine coords where it trips the limit, I then rehome and move the opposite way and do the same. These values (or slightly less) are what you put into the soft min and max.
