yes it work just fine thank

This is a useful accessory for your CNC router. Bought it along with my 3018 Pro, however I had to modify the connectors for the board that comes with the 3018 Pro.

This is a nice item! The SainSmart Facebook people have indicated that some use this, others not. Those that DO use it say that they enjoy it. I'm not surprised. Very easy to install on the computer board. The only issue is that the connector provided blocks the 5V connector pins. So, if I get any accessory(s) that require 5V I'll have to disconnect the Z Probe ... or figure out a way to remove the current pin connector and install another. In the instructional video and papers, the coding is incorrect. If you follow the video and the instructions and put spaces as shown, the Z Probe will not function. Instead of spaces, place a semi-colon (;) after the last line section thena space and begin the next line section, place a semi-colon after that and a space and finally the last line. MINE was G90G21G38.2Z-50F100; G92 13.77; G0Z25 The second line shows that my digital caliper measurement was actually 13.77 mm. Once I had done that, it worked beautifully! The other thing that the Manual does NOT say is that once you set the line in place (above) you never have to touch it again. The Manual would give the impression that you have to do this process each time. Not so! Oh ... a word to the wise. ENSURE that you write down the OLD line code in case you do have to remove the Z Probe. SainSmart may want to consider updating the Z Probe Manual and MP4 video. Other than those minor items it's a really handy feature and so far I'm pleased that I purchased it!

it certainly doe snot work the way I expected... documentation---not accurate --
