I have been running the machine for a while now. Generally it cuts well and runs reliably. I have occasionally found that the y axis freezes on startup after homing, but I think this most likely to be the Ruida controller or the leadshine encoder playing up. Either way it's usually solved with an off/on cycle. After sales is ok, quick responses but be prepared to take videos to communicate problems. This is not unique, I have the same situation with Omni (CNC router). Overall, I would buy from them again. They delivered what I paid for, the build quality meets expectation. Whether the $1800 premium is justified for you I don't know, it's worth verifying the options are specced the same. As well as the controller, servo/stepper, laser specs all the other hardware items will vary is quality and will have a bearing on performance and reliability. Buying any machine from overseas without inspection carries a risk. If you end up leaning to the alternative laser cutter, try and find a customer running the machine. I bought the HSG based on feedback on this forum.

Hi Yurtman

Appreciate your help and quick reply.
One more thing I would like to ask you...I was wondering if HSG are using them proper DC brushless servos or plug and play easy servo drive of leadshine? I've heard that these plug and play leadshine servos there aren't real helpful they make very little difference mostly on engraving.

Thanks

The machine has leadshine easy servos, which are essentially stepper motors with encoders to close the loop. Not sure why these should pose a problem for engraving. I have found they perform well.

Hi Yurtman,

Thanks for clarifying. The other option was Shenhui as low cost option and Argus/Senfeng as kind of middle price range. HSG it is our a kind of "premium" option. All the servo drive, laser pointer RECI 100W or similar laser tubs, Ruida controllers, HIWIN guide rails so quite similar parts by their specifications. Now the difference would be the price of-course and the after sale support, the level of English or "chinglish". This is my research now to find out how after sale support. This was my important criteria when I purchased my UV's and I got it right in that respect. Thanks again for your thoughts, as I've mention I'm a newbie in this field and any good advice from engineers like yourself if more than welcomed. If any other advice in terms of what should I check with the manufacturer before purchasing please let me know. Thank You
