X axis too fast when starting print.

Hi Guys,

Setting up a MKS gen v1.4 on CTC biezer.

Using Marlin 2016 Firmware.

I've just about got everything working.

controlling via TFT32. bed manual leveling works correctly, along with 'home' function.

When I go to print an item, all axis home, but on first movement it appears that the X and Y axis move far to fast and loose their correct positions.
Tried altering feed and acceleration in configuration.h file, but nothing seems to work.

Any ideas?
