Auto-Squaring with LinuxCNC v 2.8

[Kitwn]

Michael,

I hope this thread will help you get LinuxCNC 2.8 up and running without any problems.
One thing to watch out for that is mentioned on the LinuxCNC forum regarding the auto-squaring is that the sensors must stay triggered until the software tells the gantry to move again. If the cutout in your drawing were too narrow there is a risk of overshooting the slot during deceleration and resetting the sensor too early.

Hi Kit,

I'm a total newbe on CNC machines but I'm trying to learn. Problem is that there is not a lot of pictures on how to set up the home and limit switches mechanically.
I'm buliding a chinese copy of the openbuilds workbee 1000x1500 mm and ofcourse this has a gantry driven by two separate motors in Y and therfore I want to use the auto squaring functionallity.

Do you have any pictures which I can work from?

I don't have any pictures immediately to hand but you'll find plenty in the build logs. Most people are using inductive proximity sensors these days, arranged so that the part being detected passes across them rather than directly towards them with the potential for a damaging crash.
