I’m wondering if gSender may be the issue.
I’m getting this consistent cutting error.
Gemitsu 6050 Plus.
1/4" carbited 2 flute down cut.
10000rpm, 70 in/min, 4 passes at .221" per pass, chip load .0035
7/8" poplar with a 7/8" final cut depth
In the corners of a rectangular pocket, the bit overruns the line a bit, leaving a corner divot.
This is consistent on all 4 passes with “shelving” visible.
This happened with my old CNC as well.
Thoughts?
@Kevin745 I doubt it’s a gSender issue. Try more passes at a smaller depth. I’m guessing deflection is the cause.
What’s your CAM software ? And it is only a pocket cut, right ? No profile cut at the end ? No dogbones configured for the corners?
Classic deflection. I agree with @Chucky_ott
Hi Kevin,
If you use vectric and a profile toolpath (not a pocket one) you can select spiraling plunging to keep deflection to a minimum and consistant throughout the toolpath. I always use this one when I go for a cutout.
One thing to change is the plunge speed setting for the bit to normal cutting speed or you will get bored.
@Kevin745 I’ve moved this from the gSender category. IMHO, I don’t believe that your issue is gSender-related. I’m quite sure that, with the suggestions that you have received so far, you will resolve this. Please report back when you have so that I can mark it as resolved and close the topic.
