Someone take a look at this
« on: October 30, 2012, 04:42:33 PM »
Please take a look at this attachment
and tell me why this project is outside
my work area

this is the "scorpion" a practice work I got
it from here

the machine homes properly and I am able to
zero all the axis to the work material

the machine goes to point zero just like it suppose to
and then heads off away from the work piece and would
crash into the y stop if didn't hit e stop....

You stopped the machine SHORT of the starting point in the code ???

(;-) TP

if I didn't stop the y axis would crash...
it goes tool zero and then moves off the material

Look at the DROs where you stopped (;-) IF your machine did not move to that point I would look at the motor tuning STEPS PER. It would seem it is moving further per unit than it is suppose to.

I see the machine was set for G21(metric) Gcode and there was NOT any scaling it is still at 1:1

Just a thought, (;-) TP

NOW for the record HOW BIG is your table? AND where did you set X0Y0 at on the table.

well the table is set-up in soft limits max at 980mm for x
and 580 for y

and I didn't think about checking to see if the machine is actually moving
where it says it is or thinks it is....
I need to do that for sure

I didn't manually set-up the steps per it was all done when I installed the XML
from the manufacturer...
but, then I know what you mean

I didn't change anything so I assume it is 1:1 I didn't use any scaling or anything

actually, I found this G code sample on the forum here....

really I was thinking the project outlined yellow was supposed to be inside the
table represented by green outline on the table display

my always sits outside the green box

It will also depend on WHERE you place the Part Origin(home) IF you put it in the middle of the table you could run out of table. Always LOOK at teh size of what you are about to cut. THEN you will be able to tell WHERE you need to put the 0,0 in order for it to cut on your table IF it fits that is.

I always load the program set the 0,0 and then go take a look at the extents dro's for xmax and Ymax to see IF the cut will fit the table. sometimes you may have to go backl and shift the 0,0 to make it fit.

I would also do a test on your machine command a move of say 100mm and SEE if it  moved 100mm exactly.

Just a thought,(;-) TP

yeah, that's the first thing I am gonna do when I get in tomorrow
command a certain distance and then measure to see....

I used VCarve pro demo to do a sample sign they have for trial
 I didn't have much trouble
once I figure out from which corner to set my tool zero on....the machine
when straight that spot move off slightly and then cut the sign

DID it cut the sign to the proper size?

(;-) TP

that 's another good question...
I don't know about the actual size of the sign itself
but, it stayed within the material dimensions

but I'm gonna double check for that too

I need to be able to write a separate code for each axis
that will tell it to move a certain distance and then measure that
