XieChang Controller Technical
Since the new 24-fet and 36-fet XieChang (http://xie-chang.cn/index.asp
) boards are upon us ...
http://endless-sphere.com/forums/viewto ... =2&t=14798
& ... Time for a New Tech Thread.
BTW ... XieChang's website SUCKS! Even with a google translator it sucks. XieChang caters to China ... NOT US! No worries however.
(I enjoy digging for gold in the wacky world of xiechang web directories.
FYI ... I maintain my own server for ES stuff at http://188.8.131.52/endless-sphere/?M=D
(this link sorted by date).
Makes my life easier and takes the load off of ES for the tech "stuff" I like to post about.
Technology is constantly changing ... this is good.

XieChang the Company
Reading thru their published documents it is clear that they are reactionary.
All new products from XieChang result from pressure by their Chinese customers.
Many of the documents are also internal memos complaining about workers being sloppy with tools and such!
But the progress of this company is clearly driven by the expanding demand of their CHINESE customers.
So ... WE get the "table scrapes" ... but you just can't beat the price! ... Gotta LOVE China.
