Smoothing and CAM "solved"

[knastenrad]

Hello
Acorn newbie here
Been retrofitting my Deckel FP41NC now with Acorn,and new drives.
I have just got the machine running and are doing some testing with feed's and speed's.
when running some g code from fusion i get good results when it comes to smoothness of the servo's as i have been playing around with smoothing settings.
But it seems like the smoothing does not apply in the CAM function in CNC12.
Is there anyway to apply this?

Can i insert G64 to the camcycle ?

thank you in advance

hello!
not sure what your question is.. check out the operator manual for info on how G code smoothing works.

thx

the question is:
is the smoothing settings used when i use a lets say pocket function in the CAM option (Intercon) ?

[cnckeith]

not typically. smoothing is primary designed for short vector 2D and 3D G code files and does a nice job rounding off rough G code files.
or for helping out high speed routers turn corners running at fast rates.

Intercon does not create short vector g code files. so typically you would not use G64 smoothing on a G code program generated by Intercon.
and as a matter of fact you want to avoid using smoothing on typical job shop type operations created by Intercon like drilling, circular pockets, tapping, and circular pockets etc.. it should be nice and smooth.. if not, something else is not right...

what are the specs on the deckel? turns per inch? axis motors being used? steps per rev? photos? type of parts you are machining or plan to machine and attach a fresh report.zip and i'll be glad to comment further on how to get the best results. k

thx Keith!
Really appreciated.
Here is some photos
the machine is still "under construction"
just made my first chips last weekend
The servos are original Getty's for X and Y , and Gould for Z axis
All Permant Magnet DC motors
Added encoders to all servomotors ( 2500P/R 10K counts)
Machdrives BRA Drives for X and Y (20A)
Prizma / Audiohms DCS-3010-HV Drive for Z (30A)
currently running drives at ~50V

here is some of the 2 testparts i made last weekend
I will use it for a wide range , mostly parts like this and some more car related machining

here is the latest report file

[knastenrad]

here is test video of the movement with this settings testing the CAM function in the photos below
During the video i startet at 100% feedrate and increased to 200% later in the video.
Somtimes it accelerates very fast up to set feedrate and makes the Machdrives 20A alarm beep
even if acceleration is set to 3 seconds.
I see that the feedrate on the screen never goes below 100mm/min (100% feedrate)
and the feedrate for x and y is different in the generated G code

the PC is only running at ~20% processor when running cnc12 and g code
IIRC it is a i7 3.37Ghz 4g RAM and Samsung SSD

Hello.
thanks for all the good info.
first thing i notice is Steps per rev is way too low at 350 steps per rev for X and 200 for Y and Z.
read this post for more info on this subject.

and....When you rotate an axis motor by hand measure how far that axis moves and report back your findings.
