So yes, I am still a novice, only 156 hours run time on my machine so a lot to learn.
I am cutting some small parts from sheet and have found there is a slight mark that needs removing where the tool enters the job.
It is on every part, so a bit of an a annoyance.

I am using Onecnc and have the angle set to 90 degrees line to curve in, 1mm out from the job.
I had it 3mm out from the job, does the same thing but then I waste more steel.

So basically the tool enters the job line into a curve to the part at 90 degrees, and 80 degrees is the same issue. It has a mark where it enters and I am leaving a fairly heavy tab all the way round, so the part is not moving.

Any ideas to eliminate this? please.

It's likely either you are actually ramping, plunging, helixing, etc into the work. Or you need more lead-in radius. Not angle but radius.

Or lead-out radius depending when it happens

It is set to 1. It was set to 3, but did the same. So more is better you say. Any number that I should start with?

Typically yes. Or just the location it is coming in at all together.

I am not sure what you are doing. But if the tool is cutting on the bottom f the tool and leaving marks on the top of the part, you want the lead in radius in the x and z or y and z. If the marks or on the side of the part you need the lead to be in the x and y.

If you made the radius bigger on a g19 plane but enter on a g17, it would change nothing

Imagine a banana shape. I am cutting 2.85mm deep in one pass from 3mm plate. It leaves the mark vertically on the side from wherever I enter.

[chuckorlando]

Can you post some of the code? If it's on the side you need more radius in the g17 xy plane

It's the horizontal lead in radius that needs changed. All I see there is vertical. Maybe in the drop down.

Looking at the code. I do not see any lead in arcs. You should see a g02/3 with the corresponding .1

That is a little past my experience . I understand most of the very basic code that is in that file, but that is it. Without Onecnc or such I would have no idea.
What I might try then is to post in ''default'' rather than machine specific and see if that shows the type of command you mention. Default does work on my machine , so I will try that. Onecnc may have more advanced settings, but if so I have no idea where they are

[chuckorlando]

I dont know anything about onecnc. I have not watched the whole vid. But it is a onecnc "mill entry" video. I hope it has some good info.

Thanks, and while that is helpful is does not show info on the lead in and out. But I have the idea now thanks to your response and I will search that info.
