Help G41 doesn't work for multiple offsets!

[shineworld]

[QUOTE=BehemothDT;2319064]Shineworld, do you have the tool diameter loaded in tool table for tool 120?

Yes, I've used a tool diameter of 1.2 in.
To use 1.25 in I need to change G41 mode from Normal to Easy Lead In mode otherwise the g code compilator sign "Cutter gouging with cutter radius comp" error.

In RosettaCNC is possible to define 3 types of G41 compensations strategies: NIST, Easy Lead In and Normal (the default mode).
Every mode manage differently the gouging questions.

For CAM like Fusion 360 Easy Lead In is the right way.
For manual gcode is better to use Normal way in which gouging is managed better
NIST mode is the more strict way and implement the NGC274D-NIST standard.

Shineworld, I thought you had run my code in mach3. I enlarge the picture and squint my eyes and see the RosettaCNC at top.

Im very interested in RosettaCNC, but can't find much info from users. They have a cool video of some 3D embossing and such.

I went to their site and didn't see prices. I really want something that will go with most of my already installed electronics and hardware. I can migrate to Mach4 Hobby for about $300.

I only need 4 axis.

@DehmothDT,

I'm in software development team of RosettaCNC so I can reply to some your questions.

RosettaCNC is a brand of QEM srl a 40 years old Italian factory which produce PLC's, custom CNC's and instruments for industrial applications,
so RosettaCNC is an Industrial CNC with all required certificates.

The prices are not available on web for many reasons.
Price depends by hardware/software options and quantities but you can request a price with web form in rosettacnc web site just placing a valid email and your needs.

Just for info a 4 axis RosettaCNC-A start from 399E to below 2000E of RosettaCNC-B with RTCP, OPC.UA, EtherCAT & step/dir outputs and other features.

The product is not knowed outside of EU at moment.. will be.
I'm just ending the full management of Imperial system in UI to reach US needs.

The system is composed of PC software and CNC board.
PC software is used only for UI interface, G Code compiling and board settings.
CNC board is based on proprietary RealtTime Operative System and manage itself interpolations, I/O, etc,
so PC requirements are very little because all of job is done by CNC board.
The CNC manage Fanuc-B macro language with some extensions.

this is what I'm getting in mach 3

Did you input the tool diameter 1.25" in the tool table for #120?

If diameter is set at 0.0" mine looks like yours.

i was playing around with it and I see what you mean . I put 1.25 in the wear earlier , when I put it in diameter then it's pretty whacked out

You would never put 1.25 in the wear dia that would mean the tool diameter would be 2.5 dia

D the tool diameter=1.250 tool wear is only how much you want to add so if you added 0.010 this would add 0.010 to the diameter of the tool

tell me something I don't know
I'm just trying to repeat what was suggested and I happened to put the suggested value in wear rather than diameter

[ger21]

The Wear offset column in Mach3 doesn't do anything at all.

[metalmayhem]

I played around some and chopping up the code into sub routines for the finish paths resolves the problem on multiple work offsets

[mactec54]

The Wear offset column in Mach3 doesn't do anything at all.

I don't know if it works or not I never use the wear offset

But I do use a P value in the code and it work just fine

Just did this for kicks and giggles these are just straight lines, and it works as programed what ever the P value is it will offset the tool by that amount
