Folger Tech *what*, exactly? Prusa or Kossel?
Typically, for skipping, clean/polish/align/pray over the bum axis to free it up, check driver voltages, and if all else looks OK, and the motors are not overheating, turn up the drive voltage until it quits skipping . . .
If it's a Kossel, lube the stuffing out of the rails, and work them. If still bad, ask for replacements - apparently, the rails they use do have some duds . . .
