Oh boy indeed...
Your thread seems to have been started only to bash a company you have basically no experience with (thread title: CNCDrive is garbage) when in reality you probably got upset by the distributor not giving any help for you for some reason. So, why not hang out the distributor? My guess is that by the time you were through with "tons of messages with the distributor" you were so p!ssed off that you were not really polite with CNC Drive, so they just ignored you. Also, if you would be more familiar with CNC Drive, you would know that they are actually making high quality products AND large machines, as well as providing excellent after sales services. This is one of their large machine:

Now, it may not be up to your standards, but if that is a a "home made jobbie" as you call it, fine, I call that a custom designed and made for industrial use. While the company is not large, it definitely provides some excellent products, not only for hobby use but also industrially. I am pretty sure that the DG4S-16035 servo driver you are so disappointed with (if you really owned those) is also a high quality product and not really sure that it is used in many "home made jobbie", but of course, hobby users buy them as well, just like hobby users can buy anything else also. Many of them have VERY high requirements as well.
Also, the three DG4S-16035 servo drivers you received may have been crap, but I can hardly believe that they are generally a bad product since they would not be sellable if they were crap, because nobody with a sane mind would buy such expensive products if they were crap. I am pretty sure you understand that as well that "home made jobbie" users are not idiots, if the drivers would be as bad as you claim it to be, then I am pretty sure that CNC Drive would pulled back the product a very long time ago. After all, those drivers are not bran new products, they have been around for a few years now.
If your Larken drivers are fine then be happy with them, but regardless what you claim, the probability is very high that the reason why you couldn't get the DG4S-16035 drivers working is your own fault, assuming the drivers were not DOA, in which case you should have got those replaced by the distributor. But when "pleasantries eventually go south" things normally don't end well.
