Physical Max Z Height Limit for Voron 350mm

[mikedkelly]

First post, first Voron build, first everything. I just got my gantry's z belts installed and I noticed that if there were to be a catastrophic misconfiguration on my part, my gantry could derail itself in the max z direction. I understand that Klipper has a stepper_z_position_max setting to prevent this but was wondering if I should install something physical between the gantry and frame as a failsafe? Thanks for your insights.

I used the railstops from the trident.

But before derailing it should collide with the belt tensioners?

Thanks for the response. Since I am using CNC parts, nothing would collide before derailing. I think the easiest thing will be to print a small plate that I can attach to each of the four vertical extrusions right at the top of the rail. If it is a bit thicker than the rail, it will collide with the carriage. I probably have something that will work in the required printed parts that I am not using due to the CNC kit.

Looks like I got ahead of myself on reading everything before assembling. The LDO documentation includes optional z-stoppers that can be printed.
