Canon recently announced the discontinuation of part supplies for some models. For the Stepper family, it affects FPA-2500 and below. This announcement will no doubt impact all the users who have those models on the list. As the systems are getting old and require more attention, having available spare parts is critical to maintain system performance. At Exstep, we have most spare parts available (from A-scope components to Z-unit ball screw) so our customers can continue using the system for many more years, without worrying about the spare part situation.
