Helical Move will not run, What am I missing?
« on: February 22, 2015, 07:33:49 PM »
Hello,

I am trying to get the following code to run with MACH:
%
N0010 G40 G17 G90 G70
N0020 G0 X1.1672 Y-.0116 S0 M03
N0030 G43 Z.1 H00
N0040 G3 X1.1672 Y-.0116 Z.0904 I-.0422 J.0116 K.0015 F15.
N0050 X1.1672 Y-.0116 Z.0808 I-.0422 J.0116 K.0015
N0060 X1.1672 Y-.0116 Z.0712 I-.0422 J.0116 K.0015
N0070 X1.1672 Y-.0116 Z.0616 I-.0422 J.0116 K.0015
N0080 X1.1672 Y-.0116 Z.052 I-.0422 J.0116 K.0015
N0090 X1.1672 Y-.0116 Z.0424 I-.0422 J.0116 K.0015
N0100 X1.1672 Y-.0116 Z.0328 I-.0422 J.0116 K.0015
N0110 X1.1672 Y-.0116 Z.0232 I-.0422 J.0116 K.0015
N0120 X1.1672 Y-.0116 Z.0136 I-.0422 J.0116 K.0015
N0130 X1.1672 Y-.0116 Z.004 I-.0422 J.0116 K.0015
N0140 X1.1672 Y-.0116 Z-.0056 I-.0422 J.0116 K.0015
N0150 X1.1672 Y-.0116 Z-.0152 I-.0422 J.0116 K.0015
N0160 X1.1672 Y-.0116 Z-.0248 I-.0422 J.0116 K.0015
N0170 X1.0813 Y0.0 Z-.03 I-.0422 J.0116 K.0015
N0180 G1 X1.2809 M08
N0190 G3 I-.1559 J0.0
N0200 G0 Z.1
N0210 X1.1672 Y-.0116
N0220 Z.07

This is a simple helical start move to clear the center out to depth for the cutter, then cut the pattern.
MACH screams at me about the G17 plane and will not get past line N0040.
Thanks,

You have K words in the G3's, in X Y plane it should be I and J only, delete the K's and see how it looks.

The "K" is necessary for the G3 to make a three-dimension helical move, without it then it would not be a helical move... hence, the problem.

As you will see in the code window, no  K  :)

Mach 3 uses the Z instead of the K value OTHER controllers use to complete the Helix. SO just delete the K values and away you go. I had to double check your example you had Z and K.

Just a thought, (;-) TP
