Title: Job rotation
Post by: Whacko on June 22, 2007, 02:56:54 PM
I have posted on Yahoo at the Mach3 group, but I keep on getting error with my ie explorer, so I'll post my question here too.
Anyone familiar with the Burny and Lynx controllers? With these controllers in a Plasma or oxyfuel cutting application you can set two reference points on a plate to facilitate an "adjust for skew" option. This means that the controller will automatically adjust the CNC path for the plate skewness. Is this possible with Mach3 inside the Mach3 GUI ?

William I believe you are speaking of Coordinate Rotation (G68). You can pick a point and tell Mach to rotate on that point a set degree. It rotates the Base coordinates to align mach to the material. (;-) TP

Thanks for the reply vmax549, I know about the rotation function where you can enter the degrees to rotate the job, it's in the MDI screen. What I am looking for is an automated function that will adjust the nc path using two reference points along the axis that is "skew". This is a standard function in controllers like BURNY, LYNX from WESCAN etc. I have searched the forum but did not find what I am looking for. It seems that I will have to write some code in a custom screen with a dialogue whether by drop down menu or button click. If I'm on the wrong way, or am overlooking something, please tell me, I don't mind being called stupid.  :)

To elaborate, when you load a plate on a profile cutting machine, especialy thick heavy plates, you have a hard time to line it up with the rails of the cutting machine. As I said before, with generic cnc controllers you can jog to the bottom corner of the plate, set reference point A, then jog to the top corner and set reference point B. Then the controller will adjust the cutting job to follow the plate as it lies.

I have attached a photo of my machine it its semi complete stage.

Best regards,

William it is looking GOOD.(;-)

Yes we have Mcodes that will do the same thing either with a touch probe or a manual touch prob or just slip guaging it. Heck eyeballing it works too.

Look in the wizards I believe there is a wizard to do manul touch off and rotation. you jog to the two points and it will rotate the CR for you.

NOTE: OOPS , that wizard was a custom one from Brian, but perhaps he will share it if needed, I can also help you out with a mach screen to do it. Also PoppaBear has posted a wizard set to do it.

So I believe that MACH has got you covered if you need help with it.(;-)

I like your moto" Nothing's impossible" I add to it with "it just cost more and takes longer"
