This is true for the following parts, which have been addressed in the late 2016 X-Carve upgrade (*)
- the extrusion end tapping
- the X axis mod
- the set screws
- the eccentric spacers
Still relevant:
- flanged screws
- flanged lock nuts
- Y axis dust shields
- router pigtail
- motor connectors
Still relevant with new motors:
- GT3 belting
(*) I cannot help but think that this forum has helped Inventables identify some weaksnesses and shown upgrade directions. This is a great way for the community to show appreciation and offer back to make a favorite tool even better
