Turns out the connector for the RS232 is not actually soldered to the PCB. Am going to buy a USB header and solder on to find out if it actually supports the RS232 data. Otherwise have found it to be a repeatable indicator gauge. Found accuracy to be consistent within 0.02mm. Don't let the 0.01mm resolution fool you it doesn't appear to have this level of accuracy.

I recently received a gift of a 3d printer from my son. The "no cost" way to level the bed, which is required to get good prints, is to use a sheet of paper inserted under the print head extruder nozzle. You adjust the bed one corner at a time by trapping the sheet of paper between the nozzle and the bed until it has a "small amount" of friction when you pull out the paper. You repeat for each corner until they all feel about the same. Because reasonably inexpensive printers can print at about 0.1 MM accuracy this method is OK but not great. I found a 3d printed bracket to mount this Neoteck dial indicator on the print head of my printer. My first test was to use the "sheet of paper" method to level the bed then verify the accuracy using the Neoteck dial indicator. The result showed that the "sheet of paper" method was in some cases off by 0.05 MM which amounts to 50% of the accuracy of the printer itself. The method is to insert the Neoteck into the bracket then push it on the print head with a friction fit. You then can use a g-code file to position the head to each corner and make an exact adjustment. You can also move the head manually to accomplish the same thing. Usually 2 passes to adjust and reverify each corner is required to get the bed almost perfectly level. I have also discovered that the bed leveling can change from one print job to the next even if the jobs were printed back to back without turning off the printer. Bed leveling can also change by small amounts based on the bed heating and probably air circulation in the room. Bed heating is needed to make the very first few layers stick. I have seen what happens when the bed is not level even if just a very small amount. The first layer may not stick on some points or you get some "strings" on the first few layers if the design needs to move the print head in certain ways. The Neoteck device looks and feels durable and comes with a very nice fitted case. It is very simple to use and you barely need the small instruction manual. The accuracy appears to be very good. And all for about $25. So the bottom line is this fairly cheap solution has raised the print quality and the number of occasional "do overs" when you see the first few layer passes don't print correctly. If you are still trying to level without a digital gauge and have random print problems this could help solve your problem if it is related to bed leveling. If you you want to give it a try search your favorite 3d pattern site for "Bed Leveling Bracket" and "Neoteck". Read more

Product as described. Works well straight out from the box. Did some verification - it is accurate to well within the mm and the measurements are repeatable down to the 0.01mm as per description. Fairly solid construction. Obviously not sealed for use with chemicals. This works for my intended usage, calibration of saw blades. Read more

This looks like a quality product as it is even verily heavy and not made of cheap plastic and comes in a nice case. Now had I written this review 20 seconds after I tried it out it would have been a one star review. Let me explain why. I turned it on and all was good and did a few test readings on the millimeter scale. I then clicked on Inches and in two seconds it stopped working and the screen was all jumbled and unreadable. I could not even shut it off to do a restart. I contacted customer support via the Amazon.ca chat window and mentioned this issue to the Seller. The seller got back to me and asked me to try a new battery. I also had trouble opening the battery compartment as even with a sharp knife I could not pry it open. So to avoid damage I also asked the Seller exactly on how it opens and they sent me 3 pictures on how it is done. After opening it, I popped in a new LR44 battery and Bingo it worked perfectly. So it was just the battery and it had about 20 seconds of life left when I first got it. I am going to make a jig for it to use in my table saw miter slot to measure the exact distance of the blade on the left and right to make sure it is exactly the same. As as far as I am concerned this digital gauge is the way to go. I might add that the customer support is also fantastic. And yes I would recommend this to a friend or maybe even a stranger.
