LazyCam (Beta) / Re: Start engraving as drill and angle

« on: August 22, 2011, 06:13:02 AM »

Easy to fix by adding a line N1203 and G1 Z-1 and modifying line N1205  by deleting the Z part of the move.

Will need to have a look and see what LC is doing. Quickly did an offset of the inside part of the A and it plunged straight down here.

Later, RICH

You can make a tapered thread by specifying the taper in the wizard. I would need to  find my notes on doing it. The taper
input is "twice the angle" ,I think .......  just dont remember. The "T*********xx" in G76 defines the taper.  Been a long time since I  did one.

Post the LCam file ( Just as it is prior to posting code ), the dxf file from Corel, and the tap file.

Not sure how the thread repair will work but feel free to use the info in Threading onThe Lathe page 49 & 50 on how to pick up a thread.

Certainly a fresh approach to using using the wizards with improved graphics.
Have fun in your task.

How to change it for drill, or engrave again this place?

Drilling is a separate machining task and  is covered in the manual.

Think you mean how to cut using multiple passes thus increasing the depth of cut on each pass. To do that you select the offset, define the tool to be used and it's max cut depth per pass, then define total depth based on a reference and post. All in the manual.
There are more steps in the process,but, the above gives you a general how to do.

FAQs / Re: converting DWF files to g-code in Mach3

« on: August 21, 2011, 07:35:26 AM »

Henry,
You can import a dxf file into Lazycam and post code to Mach. I never used that very old version of Mach but believe it also was based on a dxf, maybe not. You can't go directly from a DWF or DWG.
The dxf provides for definition of what was drawn, even if it did accept a dwg the info contained in the drawing would need to be manipulated for use by another program or a converter would need to be included.

If you want a high level explaination about dxf files you will find it in Appendix "C" of the LazyTurn Manual.

You need to define what you want to machine and how. Any software is not a "mind reader of what you want to do".

G-Code, CAD, and CAM discussions / Re: Enroute to Mach 3 cutting problem-seeking advice

« on: August 20, 2011, 07:10:47 PM »

best way to cut incremental or absolute

There are two ways that gcode that can be written relative to a reference. The controller must be able to interpret either
coding. So by default you need to run in one mode or the other. Guess one could can write the gcode with a combination of style 
but that seems like asking for trouble. Depends on how the drawing was done and how you may want to check the code. So there are advantages and disadvantages from a coding point of view. But all this is somewhat irrelavant to your question.

I don't think the actual cutting is the true question as the machine will go where instructed to go.
I can't answer to which method may have some significant influence on the computer side of things.

So after a few lines of typing here, I also am not sure what the good answer is .

Scott,
You can work in exact stop or constant velocity ( CV).
Try the CV mode and you will see a difference in the machines smoothness.
Have a read about CV mode as there are some settings that come into play to avoid rounding of corners.
