Next version of JediCut?
December 31, 2007 10:14AM
Hi Jerome,

When do you expect the next version of JC to be released?

The software is working great and looking forward to its future development.

Cheers,
Luke

Hi Jerome,

Just worked out a problem that has been causing me an issue for a while. When using the Cut Wizard, I found that I need to enter a negative number for the "X1 Decalage". If I put it a positive number it makes one side of the cut a different size than the other.

Cheers,
Luke

Actually there still seems to be a problem with the Cut Wizard Decalage values ...

By making one side a negative number it does resolve the issue of the ends being a different chord size, but ...

- if you make the X1 a negative number and X2 a positive number then the chord at both ends is smaller than it should be

- if you make the X2 a negative number and X1 a positive number then the Chord at both ends is bigger than it should be.

To test this ... put large values in and see the results. I was trying to make multi panel wings. Till now I couldn't work out why the panels didn't line up.

Have you notice this with the Cut Wizard?

Cheers,
Luke

Hi !

I don't understand what do you want to do with the cut wizard. I program it to cut wing with different chord. If you want to cut wing with same chord, you don't need this wizard.

You shouldn't be able to enter negative value. I will correct this in the new Jedicut version.

I don't have many time to work on the new Jedicut version but I still work on it in order to add many new functionalities winking smiley

Hi Jerome,

Can I send you the profiles that I am trying to cut -- maybe you may get a better idea of the issues I am having. I have used CAD to enable the JC to cut both wing halves in one cut.

Cheers,
Luke

Hi,

I'm sorry but I don't have internet connection at home. Maybe soon.

If you want to do cut in one cut, you can do it with all profiles using the cycle of cut manager. It's very simple to use (take a look at the Jedicut's help file).

Hi Jerome,

I had looked at using the cycle of cut manager, but as I a cutting tapered wings I cannot cut the left and right part in one cut. I have been using CAD to modify the DXF file to include both wing profiles in the single profile. It has been working great except for a few small issues that I have been having with the Cut Wizard.

Slowly I am making progress. I found that if I make both DAT files the same X length and set the chord values as this length, my result is better. When you get a change to see my DAT files you will get a better idea of my work.

I have also been using this same principle to cut out complex fuselage sections. This way, in a single cut I can cutout the battery hole and external fuselage shape in a single cut.

Cheers,
Luke

Hi,

Send me your dat files by mail. I'll take a look as soon as possible.

Hi Jerome,

I have added the files in the "My Files" section on the forum. I have included the two DAT profile files and the JDC.

Hi Jerome,

Congratulations for your work !

I would like to suggest a new program setting parameter for you !
The backslash function very lack for me... ( my TR12 coils is slack )

Zoltan,

I'm sorry, I don't understand... What do you want with" backslash" ?

HCNC,

It's in project but I need time to test Jedicut's controls winking smiley

Hi Jerome,

Lost a few steps when change the cut direction (screw and nut error)... I think it's the backslash .
(see Mach3 settings for example)

Dear Jerome!

Have you thought of using a trapezoid movement profile in speeding up and slowing down the motors ? This technique could be useful in increasing stepper motor speeds! At present, because the lack of this movement profile the stepper motors can only be used in the low speed range.The program can generate higher frequency output signals. If you would use this profile only in rapid traverse mode (G00, in CNC language) the quality of of the cut would remain the same but the whole process would speed up. Of course, it would be nice if the starting and stopping speed could be set up by the user of the software, and the acceleration time deceleration also at starting and stopping. As I can see the speeds (cutting speed and rapid traverse speed) set up of the incoming pulses by dividing them with two fixed value. If you need any help ask bravely anything from me.

Best regards HCNC.


Cher Jérôme!

Avez-vous pensé de l'utilisation d'une plus rapide, rampe "courbe" est d'accélérer et de ralentir? Cette technique pourrait être très fortement augmenté par une accélération du moteur à être utilisé! À l'heure actuelle, par conséquent, le stepper n'est pas seulement le Ramp Start-Stop plage de vitesse peut être utilisée, même si le programme est capable de beaucoup plus élevés (ce qui ne devrait augmenter la fréquence de générateur de signal). Si vous utilisez uniquement l'occasion de la rampe est plus rapide, vous ne pouvez pas changer la qualité de la coupe, mais l'ensemble du processus est l'accélération.
Bien sûr, il serait bon que le premier et le dernier de vitesse au sol, et le temps de démarrage pour l'utilisateur de mettre leur propre moteur. Comme vous pouvez le voir la vitesse (la vitesse de coupe et de la vitesse) des impulsions en divisant l'ensemble en deux fixes. La rampe, le plus rapide évolution dans le temps. Il serait une valeur initiale (la valeur de la scission de la vitesse de coupe, ce sera mai), puis une période de réglage du temps pour parvenir à la division de la valeur à grande vitesse. En revanche, démarrer le moteur et l'accélération de retour réglementer, il serait break. Bien entendu, cette approche ne conduit pas à des accélérations et de freinage, mais une valeur de plus de la dur fixe de démarrage et de stop. Bien entendu, le programme doit être préparé pour cela, parce que les freins devraient être reconnus à l'avance, et le temps de commencer à diviser la valeur de l'amendement.

Dear Jerome,


Engine speed might be dramatically increased under quickrun with this
technique. Currently there's no RAMP therefore step motors can be used only
in the range of Start-Stop velocity; however the program code is able to
work in even faster speed. For this the generator frequency should be
increased only.


In case you would use RAMP under quickrun only, the quality of cut would not
change but the whole running would speed up.


Certainly, Would be great if the user could adjust the initial and ending
velocity as well as the running-up time to his own engine. As I see the two
speed (cutting and quickrun velocity) are set by the division of two fixed
incoming pulses. The RAMP would change the partition of the quickrun
(timebase) in the gear of time.


After the initial value (that could be the divided value of the cut
velocity); the partition would reach the quickrun value in reasonable time.


By this, the engine would start in quick time and stop with reverse
controlled break. Of course this solution would not result in linear
acceleration and braking but would be better than fix, hard starting and
stop.


Certainly the program must be prepared for this because the braking must be
identified and start the change of the partition value, in time.

Hello Jerome!

Which version DXF compadtible of new JediCut (V2.2.2)? R12, R11, ...?
This is usable fuselage cutting?
Thx!

Hello,

R12, but it's a beta functionality, and it seems to be a problem on the new version.

You can cut fuselage but if you have the profiles, like wings.

What I would LOVE TO SEE in an upcoming version is ...

A direct import of Stephano Duranti's Profili output !
Yes I can bring over .dat files for tip and root.
But there is the G-code output that does everything.

His 3D Sim of cutting action is terrific.
His program is low cost.

Jedicut is fairly Mature now and could become a real Force in Foam cutting.

Just think about it :-)

Thanks for listening

Bob
