VR CNC Milling V2.3 - G42 Cutter Compensation Issue

Post by EireKarl » Thu 17 Nov , 2016 21:01 pm

Hi,

Completely new to CNC. I'm using a block of styrofoam to cutout a shape which includes an ellipse.

I have all the points on the ellipse entered fine, but when I try to cut out along the right side of my ellipse (CCW) the tool jumps to the origin. This keeps happening before the very last point of my ellipse.

I'm wondering is there something I should know about G42. I've attached the sample code below:

Code: Select all

G00 X100 Y50 (Move to first point of ellipse)

G01 Z-10 F200 (Drill into piece)
F500
G42 (Cut Compensation Right)
G01	X	94.500	Y	50.000
G01	X	92.523	Y	61.805
G01	X	86.768	Y	72.561
G01	X	77.745	Y	81.312
G01	X	66.258	Y	87.281
G01	X	53.325	Y	89.938
G01	X	40.098	Y	89.046
G01	X	27.750	Y	84.684
G01	X	17.379	Y	77.241
G01	X	9.907	        Y	67.377
G01	X	5.997	        Y	55.969
G01	X	5.997	        Y	44.031
G01	X	9.907	        Y	32.623
G01	X	17.379	Y	22.759
G01	X	27.750	Y	15.316
G01	X	40.098	Y	10.954
G01	X	53.325	Y	10.062
G01	X	66.258	Y	12.719
G01	X	77.745	Y	18.688
G01	X	86.768	Y	27.439
G01	X	92.523	Y	38.195
G01	X	94.500	Y	50.000 

G00 Z2
G40 (Cutter compensation off)
The tool I'm using is an 8mm Slot Drill.

Thanks,
Karl.

You need to add a move to the code to make the tool move clear of the job before cancelling the cutter compensation. I am sure if you look in the help files it covers this.
