Title: Start engraving as drill and angle
Post by: tiririri on August 21, 2011, 05:04:10 AM

Because it's my first post... hello, and sorry for my English

I have little problem, I use offset and pocket function for letter (import from corel). In g-code i see that start of engraving is not as drill but under angle.
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.

Thanks for your reaply.
No, I have only one pass (in tool I set max cut as 10, and in real I take only 1mm so it is ok).
My problem is why tool go into material under angle (slant)? why not upright?- that I need. Look again at red arrow in above image

I see something else, if I use only offset then toll go upright, but if i add poket then each entrance into material I have with slant

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

Looks like it is Ramping into the cut instead of plunging striaght in. Check your  options

(;-) TP

You mean about this settings?
I can change it and get result, but if I open it again then I see old value

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.
