Need help in Incremental Round Move

Dear Linuxcncusers.

I am using Linuxcnc since 5 years and never get a problem like this.

I Want to move an Radius incremental with an predfined angle. I set the I and J of the Radius with G90.1 to absolut. But this will not do what i want.

I have seen the documentation with polarcoodinates and think this must be helpfull buts not true.

The workpiece is evry pice not similar to the others and there are 100 of this. The angle of Radius and the angle of the side are not the same. On my machine at Work with Heidenhain control is no problem to do this on it.

A sample it looks like this codeThe Movement on X Axsis i havent implementet.

And as Sample now my Code wich i have done on Linuxcnc
For Better Understandig i Post the Complete Code and Drawing and as sample some Pieces of the Projekt.

Does anyone have a Idea ho to do this easy without CAM and without draw each point in CAD to messure the endponts of Radius.

Sorry for my English buts not my Native.

thank you and have a nice day
Roland

Thank you andi

i have found a other reason.
In you code i think i have tio left contour parth and move back

its bad that Linuxcnc can this not with simple commands

on my Heidenhein the code has 26 lines in Linuxcnc 120 ok there are 40000 dollars diffrent.

mai be some developer read this. Pleas add simple arc round for in and outside like Mach3 or others this will be verry verry helpfull.

thanks for reading

I dont use mach 3

I see it by e collegue. He wrote the ege of the pice with x20 r2
Y-10 r2
X0 r2

So the edge are round without i and j and correct endpoint

This function is verry helpfull at miling. At work i use them 100 times a day

i think we discuss different things

Linuxcnc must use g2 for round

At work HH uses after linear move R and the arc will be roundet
linuxcnc must tolt G2 <where to travel> < Radius>

User must Calculate the start and endpoint
if move will be longer or shorter Radius must be recalulatet

when CAM is used there is the radius in clear

i like oldschool and have not cam to use

i think this explain what i mean
try it
download the trial and use then you understand what i mean

HAND

jepler ! you are right

english i snot ma native but you have checkt it thank you

@ andy i dont want spezifie an g2 or g3 move now it was the discuss abou arc rounding


example
linuxcnc
G91.1
G1 G41 Y0
G1 X9
G2 X10 Y-1 I0 J-1
G1 Y-9
G2 X9 Y-10 I-1 J0
G1 X-5
G40

other cnc Terivat
G1 G41 Y0
G1 X10 R1
G1 Y-10 R1
G1 X-5
i hop this is now clear for you what does i mean

Linuxcnc is a Goog controller but some thisgs are very very cumbersome
