General Mach Discussion / Re: Error msg loading G-code

« on: December 16, 2010, 07:48:00 PM »

My problem here is that I don't know where the top & bottom lines (at +-0.9675) intersect the arc on the end.

You can't write the correct code if you don't know that. G-code just specifies coordinates. If you don't know what they are, then you can't write the code correctly. You're trying to run before you can walk. First, do an accurate drawing and calculate all your coordinates.

Not sure if you wanted that "trapezoidal" shape. I changed it to a more rectangular shape with parallel sides.
Try this.

N011  G0  Z0.05
N012  G0  X-.5 Y1.3 (Move to start of lead-in)

In Config>Toolpath, did you check "Use Radius for feedrate", or whatever it's called?

Galil / Re: Another gantry mode limit switch question

« on: December 16, 2010, 07:30:27 AM »

I would suspect that Mach treats the gantry axes as one axis.  Thus when the limit is tripped, Mach does the same for the slaved axis.

Steve

There are two different ways to configure the slaved axis homing. The normal way is both sides of a gantry move toward the switches together, but each side uses it's own switch, to "auto square" the gantry.

The second option, in General Config,  "Home Slave with master" uses a single switch, and syncs the motors throughout the homing process.

What is the 4th axis velocity set at in motor tuning. It typically should be much higher than the other axis, because it's in degrees/minute.

As Graham stated, you need at least two lines of g-code to use G41. And that's before you even start to cut your part. You should be moving to a specified position before calling the G41. The comp is applied during the move from that point to the next one.

You ran some other code that called G18 and put you in the XZ plane, and didn't return to the XY plane.

MDI G17, or better yet, put a G17 at the start of your code, and it'll run fine.

Sounds like you're missing the J in the G2 or G3 line. you'll need to post the code.
