Default Cycle of Cut
March 20, 2009 01:48PM
Hi

If I use the 'Default' Cycle of Cut, I have alignment issues on the Horizontal return (X axis only) to start after cutting the 'extrado'. The horizontal return over shoots the initial start point with 5mm. Thus when the 'intrado' is cut the two wing profiles extrado/intado is mis aligned. In the mean time I use the 'inverse' function to eliminate this problem by doing all my cuts in a single continuous pass. Still I would like to use the default cut? Are there anyone who has experienced the same problem that might have a solution?

The funny thing is the Y axis alignment is perfect.
It's not a problem with backlash as I measured my cnc's at 0.02mm!

This is the default cut steps:
Vertical synchronous movement - Neutral, Starts Height;
Pause (2 seconds),
Horizontal movement (10mm) - Count, Standard;
Cut of “extrado”
Horizontal synchronous movement (10mm) - Count, Standard;
Vertical synchronous movement (to get out of polystyrene) - Count, Release Height;
Horizontal return (to come back to start point), - RAZ Counter; (This is where I have a problem)
Vertical synchronous movement - RAZ Counter;
Horizontal movement (10mm) - Count, Standard;
Cut of “intrado”
Horizontal synchronous movement (10mm) - Count, Standard;
Vertical synchronous movement (to get out of polystyrene) - Count, Release Height.

Hello,

Can you send me your Jedicut.ini file and your cut file (jdc file) ?

Hi Jerome

I got bigger problems at the moment! My one axis decided to stop working for no apparent reason. I'm waiting on components to trouble shoot and fix my controller board. As soon as I get everything up and running again I'll send you the files to you!

Thanks

Hi Jerome

While I'm waiting, maybe you can clear something else for me. I use various drawing programs (that is not as nice as a CAD program) to create my DAT files. I'm struggling with scale issues if I need to cut 2 different parts from 2 different DAT files. For example I draw/create the fuselage and the rudder in 2 separate files. Then I cut my fuselage and then the rudder to fit on the fuselage but trying to cut the rudder to fit to scale on the fuse is always some trial and error.

When cutting random shapes from DAT Files (other than wing profiles – thus cycle of cut points [1] & [2] is not necessary the leading & trailing edge) using Jedicut’s Wing Cut function and Symmetrical profile selected, the question I have is: The distance entered in the Wing Root Chord, is that the distance between point [1] and [2] on the ‘cycle of cut’ or is that the distance between the left most and right most coordinate in the DAT file?

Thanks

Hi Jerome

We are blessed with public holidays in South Africa for the month of April so had lots of time to fix my controller board and I'm all up and running again.
Please see attachments of the dat and jdc files I use. Also in the two pictures you will see exactly what I mean with th miss aligned halves. In DSC00072 you will see after the horizontal return to start cutting the top halve of the profile it over shoots the initial start point and you will notice this in the trailing edge picture I took. See the initial Vertical cut to get out of the foam and then the following vertical cut miss alignment.

DSC00077 is the final result.

How can I send you my ini configuration file?

Regards
Collen

Hi !

Your cut is very simple, and I take a look at the "cut preview" and it's perfect. Do you lose step when your are cutting ? I think the horizontal return is running to fast. You can modify this speed in the default cycle of cut.

To post your Jedicut.ini file, just open it, and copy paste its content in a new message on this forum winking smiley

Hi

Both my Cut & Fast speed is set to 2.35 mm/second which is already quite slow. Do you have any idea what other users with the HobbyCNC board with 8000Khz timer maybe running on?

Thanks

I'm sorry, I don't know. Do you you lose step when cutting ?

are running jeticut interface BB2001z to cut wings for model aircraft and are finding difficulties the configuration.
1 - want to cut cut a wing to wing root to wing tip and 195mm to 156mm, when we sent it to cut the cycle is put with only
30mm + or --
2 - the centralization of the beginning of the cut in Styrofoam. preview window cut in the profile is out of Styrofoam.
believe that our problem is being measures.
grateful for the attention
