Only 5 endstops?

Be sure to check out the Hall Switch endstops thread…

HALL Switch Endstops LR4

Ok, I have been going through the topics and I have spoken about using HALL switches in my build threads, so I thought i would start my own discussion so I can keep all the relevant details specific to my build. Also peeps, please let me know if this thread is in the right topic or not. Cheers. Machine Details: Lowrider 4 plan is to run grblHAL on either, BTT Skr Pro v1.2/BTT Ocotpus V1.1 or Mellow FLY D5 Board (Why? because I have like 2 ro 3 of each of these laying around from building Voro…

In my opinion, for better crash safety, it would be best to mount both endstops on the core. You’d just need to configure both endstops as normally closed (which is usually the default anyway) and then wire them in series.

This is doable with the Jackpot board, it’s just not the default way.

@Jonathjon

The endstops are only used during homing. Any other time they are ignored.

For the Jackpot board, to make the end-stop switches active at all times (i.e not just during homing) you would need to edit the config.YAML file and enable hard-stops.

Note: there is another way (again on Jackpot board) to prevent unintended crashes that does not involve hard-stops, or adding extra limit switches, and it is to measure how much travel you want to allow, and input that in your max travel distance (in mm’s) for a given axis, and then enable soft stops on that same axis.

Tobi and I use a different board.

So, asking for a friend…

If you want to enable hard stops, couldn’t you also install both sets of Y switches in series as NC wiring?

(I also am using a non-Jackpot for my LR4(s))

Not sure about that other controller, but FluidNC supports multi endstops per input.

I could chain all the Endstops together as well. Makes troubleshooting harder though.

Steve, we love the boundaries you are pushing but this thread is from a user trying to get the stock machine up and running. The advice should be to build it as prescribed, on the yellow brick road.
