G41-G42

Postby claudio » Wed Sep 26, 2018 7:08 pm

Hi!,

I red the topics about G41 e G42 code.
But I don't understand very well if I can use them and how. They are not in gcode list.
In some program there is this command: G41 D1 what means D1?
I saw some examples with this gcode and I put it in the software and run it in demo mode; the program runs but the line
with G41 (for example) becomes red; what does this mean? Is it an error?
Seeing the toolpath I don't understand the difference between G40 e G41.
I am sorry for my poor english,

thank you all for your help

Claudio

What version of uccnc are you using?

I don't think it matters but are you using a uc100, uc300usb, uc300eth, uc400eth?

Do you understand what g40, g41 and g42 are?
http://cnc-programming-tips.blogspot.co ... n.html?m=1

G40 is no cutter compensation
G41 will offset the cutter to the left
G42 will offset the cutter to the right of the cut line.

I don't think it is visible in the toolpath display it just offsets the cutter (or not)

UCCNC has two versions, a stable release for those who want it for production with minimal glitches and issues (is they have been picked up and rectified)
Available here http://cncdrive.com/UCCNC.html

And the development release which is or can be sometimes unstable ... It is released with any new features that cncdrive decide to incorporate with a view that they are tested and any bugs are raised
It is available in this thread
viewtopic.php?f=2&t=240

Current stable release is 1.2048 (and after looking in the manual on the cncdrive website g40,41 and 42 are not incorporated yet)

Current development release is 1.2106 and does incorporate g40, g41 and g42, and has its own manual which is installed within the documentation folder wherever you install it on your hard drive (normally c:\uccnc\documentation\
