Do you care to share them? Tell me what is a "better cutter" 14" and under than the Zing with an optic eye or without... Honestly their isn't... I've owned every kind of "craft" cutter there is... Zing hands down is the best of the lot...
What I don't understand if you knew there was a better cutter around then why buy the Zing?...
The better cutter is obviously the black cat it's the only one marketed as 950g of force and for cutting thick materials you need more force so you need to use a craft cutter not a Roland or Graphtec , unfortunately when I purchased the zing I did not knew about Black cat

You also don't really explain why all your posts relate to internal workings of various cutters... You went on an about GCC Cutters and China parts versus Japan parts...

I really don't know your fascination with the internal workings but clearly you have one...
Read any DSLR camera forum everyone who uses lenses professionally is also concerned about how many glass elements a lens has, what coatings are used, etc. Same for a cutter, if you do not understand the inner working like I was before purchasing the zing I had trusted KNK USA that even if the zing is manufactured in china it is good build quality all metal machine, unfortunately it was the opposite.
Yes I still need, obviously the zing is non-usable.
Then you state this...
"Furthermore perhaps anyone tested the carriage screws diameter with a digital caliper? It should be 4.00mm not 3.9x
That is because these screws need to be precision manufactured to fit the bearings, if regular screws are used then we can speak of no precision the manufacturer claims."
Have you replaced any bearings? You know even CPU/GPU fan bearings in your PC can be replaced without expensive repairs of replacing whole cooler assembly.
Bearings have certain shaft diameters, they are standardized.
How do you know what diameter screws it's supposed to have?... More over why would you care?...
The plotter carriage needs to move in precision manner, that said the rollers are on screws that should be precision manufactured to fit the bearing to avoid free play. Typical screws however are not precision manufactured because they are not suppose to be used as shafts for bearings.
M4 screw is 3.9x mm; M5 screw is 4.9x mm.
Bearings require a shaft in size of +0.00 mm -0.025mm for it to work. Some require higher tolerances.
By this it seems to me you actually weren't "looking" for a cutter but rather had one and a digital caliper testing the diameter of the carriage screws... Otherwise why in the world would you ask such a question?... We are not engineers here... We use these machine not build them. I bet not a single person here has tested the diameter of their carriage screws I mean really? You're just goofy!
Since the carriage bearings should be serviced I just asked this question, I had hopes there are more technically inclined users in this forum that would be easy to measure and check. Obviously I had Zing by that time and asked because I wanted to know if every cutter made like this?
Summa cutter do use same design as any china made cutter, 4 screws that is. Maybe they use precision shafts for bearings, I just asked I can't check it myself since there is no summa cutter rep. locally.
If I were Chad given the other posts on the internal workings of cutters... I would be pretty skeptical too...

I would never posted this if this was internally resolved by KNK USA.
