If your interested in the accuracy & quality of this, read on. Picture of the bed was after upgrade and picture of the machine was straight out of the box.I was a bit reluctant to buy this, since I was making use of a professional _10k+ cutter at a local maker space. However, I did want some more autonomy over my work. Others have covered in detail the shipping of this machine and general setup, but I want to focus (if you pardon the pun), what it will take to get the results up to a high standard.Obviously, the quality is what you would expect of a machine of this price, but keep in mind, it has plenty of room for improvement. I like to think, when you buy this machine, you have a _350 machine to start with.Unfortunately, the machine came down effectively not working. I needed to reconnect a cable for the Y axis and X axis control. That fixed the Y axis, but the X axis was jammed. Loosing the two bolts and retightening on that axis released it. After aligning the mirrors, the Y axis was straight and had very little play (0.1mm+-).The X axis however, was producing 1 to 2mm+- of "wobble". This seemed to be down to the laser head wheels being off centre. I think, looking at other reviews, I was just unlucky. This was resolved by installing a linear bearing rail on top of the X axis rail and printing a number of parts to hold the laser head. Now both axis are pretty within 0.1mm of play. I like to think now, I have a _2k machine now.Next up, I built a custom bed which hung on the internal frame and could be raised up 1mm at a time or finally through adjustment screws, complete with honeycomb. Its now producing cuts which are indistinguishable from the machine at my local maker space, minus the bed size.Next upgrade will be a laser dot, air feed and current meter. I haven't even got round to thinking about an upgraded controller board yet, because, I have yet to see the need.Overall, with a little bit of work, this machine will work a great and do most jobs you can throw at it. Spend some time tinkering and you'll have an amazing machine for the value.
