    I live this. it works too well. now i know all the issues, with flex, movement, repeatability, out of square. I recommend this if you have a router based 1/4" spindle/collet on your cnc.

    This thing is awesome. A little on the pricey but well worth. I can pretty much tram my spindle dead on with this thing.

    Super easy and accurate spindle tram

    Posted by SandovalFam on 7th Feb 2019

    I have a Shapeoko 3 XXL. I just recently tuned it up and got it dialed in. I tried surfacing my spoilboard and a piece of aluminum but I ended up with deep ridges all across the material. I tried tramming with my dial indicator in my spindle and a piece of mirror/glass leveled off of my spoilboard. That made an improvement but I still had noticeable ridges. I bit the bullet and purchased this tram. Once I learned how to use it, I had my spindle trammed in about 30 mins. I got the x axis to within .0005 square and the y axis .0015 square. This thing is awesome!!! I surfaced my spoilboard once again a and I have slight ghost lines but nothing that I can feel. One more thing, the customer service from Edge Technology is superb. I paid $112 plus shipping for the mini pro tram on Monday 2/4/19. As of Tuesday the price went down to $99. I shot them an email and asked if they did refunds on price decreases and sure enough they refunded the $12. So to sum it up, the tram works like a champ, it looks awesome, has a hefty feel to it. It has a good looking solid case with excellent protection and the customer service is outstanding. I would buy again and I recommend anyone considering this to pull the trigger!

    Great tool to tram my CNC machine

    Posted by Thomas on 26th Apr 2017

    Great tool to tram my CNC machine. The only issue I've had is one post is sticking after 1 use. I have not tried to contact the seller yet to find out what I need to do. I got my machine trammed and just haven't gotten to it. Instructions were clear and easy to follow. It doesn't hurt that it looks sharp too.
