Mach Screens / Re: The Coil winder sceenset (wow)

« on: September 24, 2011, 08:32:08 PM »

I think the 1.17mm offset is because of the the "backlash" in the wire-moving mechanism in the machine it was written for.

What I want to know is, how do I zero my machine? Does the screen do this for me? If so, when?

I think this would have worked really well as a Wizard" in the regular screenset, but I am wishing for so many things that are not on the coilwinder screen, it is not useful as it is. I

My biggest gripes with the current default Turn screens mirror others I have seen in this thread-constantly jumping back and forth between screens, and it is not always easy to get to teh screen you want-sometimes it takes as many as 3 clicks. I think you should be able to get to any other screen in 1 click, no matter where you are.

Also, I would like to have FRO indication on all screens-that bit me recently while threading(and is how I discovered that FRO is no longer locked out during threading)

I have never been able to figure out what Home Z and Home X do, as opposed to Set Home Z and Set Home X, which ref the axis in question.

Zero World?? also not undestood by me.

Things I like about the screens is that they are not cluttered.

...and even stranger, when I post and open the tAP file in Mach3Turn, it appears as if the Roughing path is in Diameter mode, while the Fine Path is in radius Mode!

I made the draing a little large in both X and Z extents, so that the tool will move farther positive in both axes, thereby taking up the axis backlash when it moves "back" to the spot where it actually will cut.

The roughing toolpath looks good, but when I set up a Fine path with the following parameters, it again tries to take a chunk out of the piece:
Clearance: 0
Final Pass: 0.001
PerPass: 0.005
Tolerance: 0.01

It also looks like the fine path does not cut all the way to teh profile.

What am I doing wrong?

PS I see thatthe Zoom Out and Zoom IN in the menu pulldown are backwards

Hi Rich:

Unfortunately, i am using SmoothStepper, and waiting with bated breath for teh plugin with backlash comp enabled-due any day now!

Thanks again,

Andy

I may just be thick, but I don't see anything in Appendix F that lets me change where the cut starts on the profile. All I see is a long explanation of coordinate ssytems and tool table.

Hi Rich:

I thought about setting it up the way you suggest, but that means that I would be advancing (negative) in X, then retracting as the cut progresses toward the chuck. I thought that wouold be a bad idea with the amount of backlash on my X axis.

The way I have it set up, I will be advancing(going negative) in X for the entire pass.

I just printed out the manual and will read it more thoroughly tonight-thanks for teh pointers!

Try grabbing the yellow arrow and draggin it to the left to indicate a different start location..

Art

Trouble is, i want it to start further to teh right, so that in going way over there, and moving some distance back to the left befoore machining starts, it will take up the axis backlash.
