Need Help!- WinCNC Problem?

[Absolute Steve]

Does anyone use WinCNC with V Carve ? I am having problems with G2 lines that error out. If the line starts with G2 I need to remove the G2 and the I and J to make this program run. Only leaving the X and Y position. I am new to G-code would appreciate any help. Thanks in advance.

I don't use WinCNC but it sounds like you are not commanding a G1 or G0 after the G2 line. When you execute a G2I()J() line and the following line is a X,Z move then you have to specify G1 for liner(feed) move or G0 rapid move.

Exapmle
G2I1.2J.5
X1.Z5.---machine will alarm out at this point because your G2 is still active for this block. A G1 or G0 is needed with X,Z

Can you post the code that you are having trouble with and mark were the problem is so we can look at it to see what’s going on?

It sounds like you arc setting are of g2 and g3 are arc settings i would look at that.

[Arc Settings]
arc_err=.01

I think helper is right, try setting your arc_err to 0.1 or .005 (mine is .005) in your .ini file. Noticed from your other post it is currently set to .02. In g-code G2 and G3 are arcs, removing the G2 and IJ make it a staright line (G1) move rather than an arc.

Stevo,

Here is a sample I was having problems with. The G2 line in the center is the culprit I assume. Thanks for taking a look.

Can you send me the whole file. Looks like some things are missing. I can do a simulation on my system and see whats up. Also what post are you using in vcarve? What machine are you running it on?

I can give you the post i use with wincnc and v carve. Havent had any issues with mine yet.

thanks,
