Easy Test For Squaring your CNC

Instructions on fixing any errors are here, docs.v1e.com/electronics/dual..., using M666
This is the GCode that was running in the video, you can edit it to fit your machine. The further apart the points, the more accurate your test will be.

dang Ryan, I had no Idea that the LR3's rapids could be cranked up that fast. Nice! Thanks again for a great contribution to the maker community.

[@AzaB2C]

Nice fast rapid moves. Very helpful info, cheers for sharing GCODE in the description Ryan!

[@design8studio]

That is so cool. Smart method! I gotta get me one of those tiny touch plates. I like how it stores right there on the gantry - unlike my inconvenient thing that never gets used.

You only need three points. There are G-code senders that have this feature. G-sender is a free grbl based software by Sienci Labs that can do this. It coaches you through each step & after you give it your measurements it will tell you exactly how far & which direction to move one of the Y-rails in order to square it. When I setup my router it advised me to move my rail 0.4mm towards the front of the table. If the x&y axis’ are any multiple of 3&4 the diagonal will always be a multiple of 5. This makes it easier when reading your tape and calculating the correction. The opposite corner will take care of itself if the Y-rails are parallel.

Yup you can do it that way as well. Doing it this way gives you a sense of your overall error since the difference is more than the error. This stops people from chasing too may zeros measuring each axis length and endstop offsets, two measurements quick and easy. Getting under 0.5mm error over 8 feet is usually where people stop. This also offsets the error in firmware so you do not have to worry about what software you use for sending or CAM. I try to make sure people can use any software they choose including gsender.

Hey, consider putting a link to the tiny touch plate in the description!

[@Fl0ppymania]

Man thats fast.. how do you archive F17000? I use Marlin and i try to mod the max_travel and so on... nothing happens i cant drive that fast. Any ideas?

[@MakingStuff]

What 3d printed piece are you using for dust collection with that Makita router?

[@allted]

It comes standard with the makita mount. With a little classy blue tape to try and catch all the hdpe chips.

[@limebulls]

Awesome! Is something like a "PINDA" / "auto adjust z height" possible for the lowrider? Haven't found any documentation for that

[@allted]

No you need the touch to account for tool changes. Everytime you swap an endmill the position will vary in the Z direction. Different sizes would also likely trigger the probe at different heights if you reversed the probe.

What app do you use to control LR3 in the video?What hardware needs to be added to LR3 to support this app?Thank you.

[@allted]

ESP3D on an SKR Pro. If you search the site/shop you will see some info in the product page and of course lots of us have been using them in the forums.
