I have a question on the photo attached... My job will be cutting 6 parts out of the 12 x 12 piece of .125 aluminum sheet. This sheet is crazy glued to masking tape applied to my spoil board and the underside of the aluminum plate. The spoil board is then clamped at each corner to the machine. The crazy glue with masking tape for clamping down aluminum is apparently all the rage with machinists these days. Assuming my job is working only within the confines of the 12 x 12 aluminum plate and assuming between tool changes the machine wont be bringing itself to machine home (that it will just leave the spindle where it last was or bring it back to "work" home).
Do you see any danger in the spindle hitting any of my 4 clamps here? they are well away from the work but I wanted to make sure before I run the tools (I will need 3 tool changes).
Normally the machine would jog to the new location with the Z-axis elevated fairly high based upon internal safe heights.
Then when the job is done, again depending on settings in the controller...it should just shut down and raise up. It should not be going back HOME...by default they are not programmed this way, but it is an option.
Interesting, I was going to reply that he was safe because the machine returns home at the end of running each file as mine does this, I did not know this is not a regular feature
My AR-16 Elite returns home after the job ends (by default) as well. When starting the job from "Home", it slowly moves down to the programmed Safe-Z height as it travels to the start point of the job. If this height is lower than the top of the clamp, there could be a problem. There have been times that I thought it was going to hit a clamp on the way there (but it didn't). I kept my hand poised on the e-stop button. Presumably, if it doesn't hit the clamp on the way to the job, it won't hit it on the way "home" either, but I've never run a job where it finished cutting (very) far from where it started, so that may not be the case. You might consider "running" the first part of the job with no bit, starting from "home", then place your clamp where you know it's completely out of the path from home.
