HI Guys
Anyone offer an ideas , I have been trying to make a small batch of parts , but having problems with the size of the finished parts in "x"the first three came off spot on the next one was out of size , so adjusted the size in the text / coding file , all the offsets set correctly , investigated the pulley / x axis drive the large cog on the axis was a little lose so tighten that reset everything .. re set the coding / text , got it running spot on then back to the drawing board , duff parts again ... the error varies around .10 and .25 of a mil sometime .30.
Any ideas would be a big help... I am running out of brass rod and hair
Best regards
