I am new to this area. I generated some g-code , when cutting the piece one of the y-axis does not move as far as the g-code states.
steps taked:
calibrated machine
created DXF in AutoCad
created toolpath in Aspire - save as g-code (inch)
the y-axis movement should be .25 inch but moving about 1/3 of it.
this is repeatable and error in the exact same place. I even moved the starting point to see if calibration issue.
if starting at 0,0 on the table or at the farthest point on the table I get the exact same results.
any suggestions would be appreciated.

It looks as if you are loosing steps, slow the machine down by 50% on acceleration and velocity and try again.

I will give it a try. right now everytime I try milling anything I get "limit switch" when the machine only moved 7" on the x-axis and 5" on the y-axis.
no where need the phyiscal limit switches. the logical limits are 42" for x and 24" for the Y.
the "abmornal condition" state axis are not refed to normal conditions"
should as I figure out how to clear this I will slow down the machine.
thanks for yor help.

OK, hav ean interface issue with the limit switches, fixed that :-)
I lowered the velocity / acceleration down 50% same issue in the exact same spot on the piece. seem to be the first movement up the yaxis.
the first move of the cut is a yaxis movement toward home and that is perfect.
I am starting my cut at 0,0 do you think moving the starting work location could make a diferrence?
-
moving velocity / accel low or high does not seem to make a diferrent it sems to be at the same point each time.
could it be the torque of the motor I am using is not strong enough?
