Digest Number 3072

Post by K Ohlgren kohlgren@gma... »

leson the m09 issue. i did as asked on the pen up with no effect
then i noticed on the pen down it had this
if(toolClass == "MarkerTool") or tool > 99 then

i pasted that in and it had no effect either


on the rising z axis post;
if i scribe a short straight line it does fine
if i scribe a circle the z axis motor rotates up
i guess i've never scribed a circle first


i scribed a square then circle and had no rise on the z axis
the i changed the sequence to scribe circle then square; same file just change in sequence
with the circle first i have z axis rise then steady for the square


at this point i am not actually scribing, using the output to turn my laser cross hairs on/off

Do you have the correct Z offset for the scriber in your post?

For the M09 issue I checked and it is a bug in the post. Look for
function OnPenUp() and change this line:
if(tool > 99) then
to:
if(tool > 99 or toolClass == "MarkerTool") then

modified the air scribe mount.

i edited the scribe offsets in the post for the new air scribe mount,
that is all i edited in the post. now when i scribe the torch comes
down, touches off, moves to z offset, moves to the new xy offset and
scribe turns on. scribe on also lowers the air slide mount. that is
all good, but now the z axis moves up, maybe a half inch scribing a
3/8'' hole. so i scribe air now.

anyone have an idea of what went wrong? all i modified in the post was
the scribe offsets.

i should have posted this gcodethe part is a rectangle with half a circle cut into one edge
i have the scribe starting midway on the half circle, then the rectangle and finishing the half circle
i can see what it's doing just can't figure out how to fix it
it appears to be rising to z0.9 (my plasma rapid height) my current scriber offsets are:
scriberX = 0.00
scriberY = -85
scriberZ = -00

i have z at 00mm now so i can figure out what i need to go up or down
at the end of the gcode N0260 G00 Z0.3937 zaxis dives from .9 to .3937
this gcode has the suggested m09 fix in it that doesn't work

I had similar problem and it was that while I am set in the XY plane, any reference to the perpendicular plane (Z-axis) within the G02/03 code is treated as a helix move. I assume you are also working in the XY-plane and I see your Z axis referenced in you posted gcode.

"N0190 G02 X6.0450 Y5.1273 Z0.9000 I0.0003 J3.1250 F50.0"

It should move the distance specified with in the G02 move.

You may want to look in the OnArc() function to see if there is a problem in there.

Are you sure you are using the edited post? I just tried it here and it
worked as expected.
i scribed a square then circle and had no rise on the z axis
the i changed the sequence to scribe circle then square; same file
just change in sequence
with the circle first i have z axis rise then steady for the square
I'm not sure what is happening there. Could you send me the job file so
I can test using your settings.
