G41/G42 interference

[MrSnow]

I'm having issues while trying to run my g codes

T8M6(Radiefres 45gr 25.0) (Tool)

G54
M3S8000
G90G43H8Z1.
G1Z-3.4F5000
G41X0Y-25.5F1600D8
G3J25.5
G3J25.5

M11
G30G0G91Z0.
G0G90G55B0.X0Y0.
M10

G55
M3S8000
G90G43H8Z23.
G1Z20F5000 (This is where is stops, and says G41/G42 interference)
G41X0Y-18.75F1600D8
G3J18.75
G3J18.75
G0G40X0Y0
G0Z100.

Any help would be much appreciated

hy mr5now, each time when i had a problem with a compensation code, i have calculated the coordinates, then i went back to the machine, and checked if the machine is outputing those coordinates

error is a line before g41, thus there may be a problem with comp lead-in movement : try to increase the clearence, like at least 5-10 x tool dia; if this does not work, then check the toolpath

why do you repeat G3J18.75 in G90 mode ? kindly

You are missing a start point in the 2nd contour after changing to G55
... if it is the same hole, delete the G55
... if is on a 2nd part, add a G0XY after the G55

just noticed.... you are missing the same on the 1st contour
you seem to have been lucky that any worked

[MrSnow]

I'll try your suggestion

G54 and G55 is used because there are 2 different positions/holes

[Superman]

Scrap my last post.... I just read your code better

Queries...
what value do you have for tool radius (D8) ?
... must be smaller than 18.75

single step thru your program so it won't look/read ahead.... it would error closer to the offending line
... how does the program go if D8=0 ? (with tool out of the spindle)

[MrSnow]

I'll give it a try

I also tried the G0XY that gives a macro error, i also tried G0X0Y0 which doesnt help with the G41/G42 error (which i didn't think it would)

This is how my entire code looks like now:

[deadlykitten]

please, why is G3J18.75 repeated twice ? does it cut 2 full circles ?

i guess that those are not 2 halves, since there is no XY coordinates / kindly

(Retract out of the hole here before moving on.)

Remember the radius of your tool has to be smaller then any radius you try to create the whole time cutter comp is on. Including lead in and out arcs if used. If not you'll get an alarm.

The rest of your code has the same problems as above.

Do you want this program to repeat continuously? If not, change your M99 to M30.

This is software generated program still interference error occured. please give some solution

[the_gentlegiant]

I back-plotted this code and it didn't make any sense with the shapes it created.

How about showing a simple drawing of what you're trying to do. What tool diameter are you wanting to use? This almost looks like you are trying to do 3 axis simultaneous helical path.

More details offers the chance of more meaningful help.

It may be that you don't have a T8 call for that new block of code
