The thread you mention is here: Spindle options for Stinger 1 - CAMheads CNC Router Forum By: CAMaster CNC
You have been banned due to your repeated negative comments towards the brand on a branded forum. Which by the way, happens on all forums.
Actually, for those that know how, it is relatively easy to "throw" any spindle on any brand machine. Not so much if you don't know how. What will not happen, and this is common to both OEM's that I have worked for, is that the OEM will not provide how to information (free tech support) for products that they don't sell. Tech support is included, as required by the enduser, for all OEM supported spindle upgrade kits.
Do you have a Chinese spindle? How about CAMaster Stinger as mentioned in the thread? Or, as usual, are you just attempting to start a thread that you can interject negativity in towards the brand? Shame on you!
