Thanks for the replys Guys! :-) That would explain things. I was using the debug print commands and when moving the Y axis with 3 axis enabled I was getting a different number return on PPDATA then I was with the Z and X which were the same.
Z, X returned 64511 and so did Y positive move. Y negative returned 62463! Another issue could be that the pluto-p card I had was bad all along! It wont communicate at all now with EMC. It loads the firmware but when going into EPP mode communication fails. The folks at fpga4fun have kindly sent out a new card which is currently in transit. In the meantime I purchased a 7i43 card from Mesa which is also in transit from the States. BTW The pluto-p card was connected directly to the port for all tests. On another note with regards to the maillist it seems I do not receive the posts that I send but I do receive replys. I am using google mail does anyone know the reason for this as it can be quite frustrating.
