Evening,
Last night i updated to 2.7 pre on one of my plasma cutters and .........it now makes ROUND corners all the way. :woohoo:
See attached pictures, on one is a pattern as it should and was untill the update, on the other is what i got today @ 2600mm/minute so it is even worse @ 3300mm/minute i usualy cut the 3mm mild steel plate.
All this is without any changes to anything, just updating from 2.5.4 to 2.7.
I have tried the G64 P0.01 with the same result, with G64 P0.01 Q0.1 again same, with G64 AND G61, still the same result.
I did just now try on this laptop ( diferent from the one on the machine ) , same result as the pictures show.
I will try to fidle a bitt with it and see if i can figure out what is going on and report back.

Also noticed that when i switch from Joint Mode to World Mode, the max velocity set in .ini file does not aply anymore, it will move above the set speed.

Later,
Tom

Update,
It occured to me that i read on several posts here that a Q0 after G64 should cancel naive cam detector, so gave it a try and low and behold, it works.

Thank you very much to all of you who are working and contributing to this astonishing piece of software, it is for all intents and purposes, a marvelous achievement. Personaly, i spent a lot of time learning the inner workings of it ( mainly HAL and setting it up as i acualy need it to be depending on the hardware), and i sure as hell don't regret it, i really am greatfull for it.

It is possible that you would find better behaviour in the Joint_Axes5 branch, which will probably be merged into master in the not-too-distant future. This separates the concepts of axis limits and joint limits.

However, it may be that you just need to specify a [TRAJ] MAX_VELOCITY as well as the individual [AXIS] limits.

Thank you very much, i will give it a try although during normal usage it does not matter at all. it works perfectly, did a lot of cutting today without a hitch. Will continue to use it and fidle with it every day and report back if i find anything.
Respekt,
Tom

The new TP has changed a lot for me as all my parts are better quality, and take roughly half the time to make. If it were to exist a year ago, and cost a few hundred dollars I would have bought it since it's that useful.
Now everything goes so fast jerk comes into play. I'd love to see a Kickstarter or some sort of pool for donations to entice somebody to get jerk worked into the TP. I don't know the policies of so forth so consider the fund raising just a suggestion...

I agree, the higher speeds are making jerk more of an issue for me as well. (especially on the wet noodle of a machine I'm working with). I wonder if the old parabolic blending introduced a form of jerk control (besides just making it slow) that may have been helping to smooth some of my machines faults, that the circular blending is uncovering.

Hmmmm last 2 post are interesting to me since i have a lot LESS of jerking and way smoother corners and especialy much much smoother arcs, then again i cut at 2000mm/minute minimumall the way to 5400mm/minute. I also use at least 500mm/s acceleration.
Again nice to see people using it and reporting here about their findings.
