Just a few words about the SMS-303 board from CNC-Plus:
I purchased that board a couple of weeks ago and had it delivered within 10 days at my door. At first glance, it looks great, well built, with optocouplers for driving 24V external switches, plug-in terminal strips, a huge heat dissipator with a fan etc.
Things became a little more complicated at configuration stage... provided (downloaded) documentation is really poor, and unless black-magic is your favorite practice, jumpers settings can barely be done as per provided information (according to the manufacturer, you may configure JP1 - a set of 3 pins in a single line configuration - to achieve a setting out of 4 possible ways. Great.) Several other jumpers and pots are undocumented etc.
But the reason why that board rapidly reached the recycle bin, is that it finally never worked at all. After several hours spent to check out the clock/dir signal etc., I found out that 2 on-board fuses were blown (not to say that these fuses are totally undocumented). Replaced them with 1.6A flink fuses as per original, I discovered that the fuses blows out as soon as the module is powered on, even with no external connection. Also found out (and corrected) soldering leaks at one of the board, but still no progress.
Sent several e-mails to the manufacturer, did never get any single reply. Nevertheless, I admit that I wrote my message in english, neglecting the fact that the manufacturer's 'Technology' contact address clearly states that "(Language: German / Polish)... So sorry, I have no time to learn Polish so choosing an alternative product (and supplier) was my final choice.
Not worse the 160 EUR... but looking at it the positive way, I'm glad I had this experience, let's go back to serious manufacturers
