David, Great info!!! I live in the UK and I'm currently working on my own metric system, 4.8 meter version (16ft) can't quite get to grips with much of the components required, but slowly taking one part at a time and moving on. I've designed a sliding block on a rail with a manual stop, that was all very easy, now the difficult part, now I'm concentrating on the motor, pulleys, belts and digital key pad. after watching your video Servo motor it is thanks. I have my own joinery manufacturing business and badly need a system like this I've been looking to buy one of the auto stop fences but at around £10,000 ($14,000) I've decided to make my own. The manual system I've built now is working perfectly and has improved everyones productivity hugely, but just taking it a step further as a bit of a project. Again Thanks

Regarding kerf compensation. You can move the position bar 1/8 more and lock it in.

This is fantastic, I'd add a manual jog wheel.

Nice project David! I don't quite remember, but it may have been your channel that introduced me to Teknic and I subsequently built a 2'x4' CNC machine with ClearPath servos and Linux CNC. Great system - couldn't be happier! I am curious as to why you went with a NEMA 34 motor for this application. I haven't been to the website for awhile, but you seem to imply that the "pulse count" mode is only available on '34s - true?? For me, more information on using timing belts (tensioning, tolerance, ...) would be welcome. I'll also 2nd the comments on a flip stop. Necessary for my smaller shop as well.

David, really nicely done. One suggestion that comes to mind is to make the stop flip up out of the way for cutting long stock manually. Also, with some trig and the right stop geometry, you could build in compound angle cuts for crown molding. Again, super project!

Great suggestions! The flip up is a must do since the stroke length is not a full 8ft. Or I could get a bigger shop.... I'll get right to work on the flip up :)

I'm Missing something somewhere as I can get this to work.

David - I loved this project when you first released these videos, but now I am actually planning to make one. I too was looking at the AT5 belt profile as they seem to have the best position accuracy, with the least amount of backlash. How do you compensate for backlash in your system with an Arduino? Thanks.

That is a very expandable build, if it had a cut list and an automatic cut off saw, a person could get quite lazy.

AWESOME ! This would work for any single axis adjustment. I can't find the arduino code.

Its at the very bottom of the project post on the Neo7CNC website. Thanks for watching

make the fence able to lift up so you have the option not to use it if your piece is longer than the travel of the machine

Nice project, have you ever made something similar using steppers and drivers ? Would it be possible to change your code to work with them ? I do not have the knowledge to make such changes, I'd appreciate if you could help me with it. I'm from Brazil, here we don't have those products, and anything we can find on sites like aliexpress are really expensive to import.

Did you order your brackets with the bearing in them or did you Fab them yourself and press the bearing in them.

I made them myself. The Fusion360 design files are on the Neo7CNC website. Look under the "Posts" menu and you should fine it. The parts list is there also.

Can you control the servo from the USB port? As would look to replace the Arduino/Screen/Keypad with one of these (if I was in the US) www.microcenter.com/product/439773/tw70ca17_tablet_-_black Note has two USB, one mini for power, and a full sized USB 2.0 for controlling something.

Maybe you could send a bluetooth signal from that tablet to an Arduino board that has bluetooth capability. You would still need to initially program the Arduino board to understand what to do with what commands you were sending it, but then it could be closed up in a tiny project box located near the servo.

Doable, but would prefer keeping code running in one place. Would have to write a touch UI for the tablet, guessing that using NW.js (or Electron) would be the fastest and most flexible route. Guess one advantage going BT would be can control multiple machines from one tablet.

Also wonder whether a self adhesive measuring tape, and a camera (moving parallel with material, but tangent to the cut end) streaming to the tablet would be better. Push a distance through the saw, until hit the desired length, and chop.
