What happened?

The end stops only correctly work after they get triggered once. So no big issue if the machine is in the middle of the work area. If the machine is booted in a position that an endstop is triggered that endstop is ignored and will try to home that axis and grind until it errors out.

An easy test is to boot a board with Normally closed end stops in the config file and run $limits. All endstops will show open until they get triggered once.

I have the same issue reported in this ticket. This is true with V1e jackpot board and three different ESP-32s (Genuine espressif, genuine V1e, and amazon clone).
I also have the issue with a release candidate version of the upcoming Jackpot V2 (integrated genuine Espressif ESP-32).

Works fine in 3.9.5, broken in 3.9.6 and 3.9.7.

#2 – Z3r0shin 于 2025-07-30

I too have this issue. I have an MKS DLC32 V2.1. I do also have the check_limits: true under the start section.

#3 – bdring 于 2025-08-01

I was able to reproduce this issue on a Corgi controller.

#4 – bdring 于 2025-08-04

There is a PR that appears to fix the issue.
