Neoteck DTI Digital Dial Indicator 1''/25.4mm, Fractions/Inch/Metric Digital Probe Indicator, High Resolution: (1/128")/ 0.0005''/ 0.01mm

I purchased this to assist in leveling the print surface of my 3d printer. After printing a mount for the x axis, it works wonderfully for my purposes. Very accurate way to level the bed. Wholly recommended

I'm not a machinist or an engineer and I'm certainly not qualified to comment on the relative quality or accuracy of this instrument in a broad sense, however, if you are (like me) a redneck with earthly predilections who wants to cull and match carbon arrow shafts and find each of said shafts' radius of greatest resistance to deflection in order to optimize the accuracy of same when fired from a well-tuned modern compound bow in order to punch holes in four-legged animals that will let all the blood out in the most reliable and predictable manner... Well then, this is a pretty darned good bit of gear. Really, for the purposes of spine-matching arrows, the relative accuracy of the instrument is far less important than the consistency of its measurements. I have limited data to make conclusions from, however, for what it's worth, when I measure the same three arrows ten times each I get the same measurements for deflection and spline each time.

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".

Using to level the bed on my 3D printer. Printed an X carriage adapter from Thingiverse that fits the loop on the back of this indicator perfectly. Really nice to be able to separate the leveling and gap setting process into two steps as it should be. First use this indicator to set the distance from the X axis to the bed surface equidistant over the whole bed. Then set the nozzle to bed gap near the center and it should be the same everywhere. Getting consistent filament "squish" which leads to great part adhesion and less/no curling.

Data output protocol uses standard Chinese serial protocol.Resolution of mm on screen is 0.01Resolution of mm on data port is 0.005 (TWICE the screen resolution)Caveat Emptor: Prolonged idle spindle movement causes auto turn off.5 stars given the cost and better than advertised resolution.

So with the exception of the RS232 port it advertised, it works fine. A nice device, good workmanship etc. I think the description should be amended to omit the info that suggests you can download from it. The issue is that there is not a receptacle that is suitable to mate up to typical data connection "plugs". A separate transfer cable is available from clockwise tools but it has the typical micro USB. The Neoteck does not have this feature. If you don't want to down load to excel or other electronic data transfer this will work fine. Otherwise I suggest you consider purchase of the Clockwise version of this indicator which is shown with a micro usb.

I built my own mount for the indicator that slid in the miter slots, which took a bit of trial and error, but once I get it working, was fantastic. I used this to help me get my table saw aligned within 1/1000 of an inch, and it cut like butter by the time I was done.The mounting plate can be rotated so that the eyelet is facing horizontal or vertical, giving you good flexibility for using it.

Good for the price, but similar to stuff found at Harbor Freight. I comes with a backing plate to use a magnetic arm mount. I was disappointed that once you put the backing plate on the indicator no longer fits in the case. The case was nice, but who wants to change the backing plate every time you want to put it away.

This digital indicator is a great value. Although I do not have a way to test or prove absolute accuracy, I can say that the unit was tested for repeatability and passed with flying colours. My intention was to use this indicator to test for "difference" readings of build-plate height for 3D printing and it helped me to tram the bed very quickly with ZERO guess work. Using one of these makes 3D printer bed leveling a breeze.To help anyone that purchases this unit, and wanted to mount it to an Ender 3 printer (compatible with direct drive conversion) there is a mount specifically made for this indicator. Check on Thingiverse for "NeoTeck Ender 3 side mount"

The button detent for zero is stiff and often results in the indicator jumping a thou or 2, clear lens on readout is flimsy and will break easily, Indicator Point threads were jammed and attempting to swap out the Point is not recommended. 3 Stars at about 20bucks, build quality doesn't demand more than that.

Definitely much more expensive than other cheap analog dial indicators, but worth the extra money. Feels very high quality and has some weight to it. Rod slides smoothly and gently springs back to 0 at rest. Digital dial is much easier to read and more accurate than analog. Comes with a very well designed and sturdy storage case, and extra back plate for the dial indicator that has a loop for mounting it to other objects. Overall, very pleased. $30 well spent.

Super produit. Je l’utilise pour le nivellement de mon plateau d’impression 3D. Extrêmement précis. Vient avec une boîte de transport/ rangement. Sur le site de Thingiverse il existe plusieurs « mount » pour le fixer à notre imprimante. J’adore.

I originally received a defective dial indicator and left feedback reflecting my dissatisfaction. However, the seller contacted me and offered to ship a replacement to me at no cost. The new dial indicator appears to work correctly and be as advertised. I haven’t used it yet to verify. I would definitely buy from this seller again. The corrected the initial problem and went above and beyond to ensure everything was good. Thank you!
