Shapeoko 3 Feed hold, Bitzero and Bitsetter

I am installing a Shaoeoko 3 Xl into a community workshop, due to this I have had to install it within an enclosure that would stop the CNC from operating when the doors are opened.

After posting on here and contacting support I was advised that I could use the Feed Hold input for this. I have it wired up so that if the door is opened the Feed Hold pins are shorted and the CNC stops moving.

I have just installed a Bitzero and Bitsetter which are working as I expected but I have discovered an issue and I don’t know how, or if, I can get around it.

If I commence a probe on Z the axis drops until the bit touched the probe plate, I then get a message telling me to disconnect the magnet from the router. I then open the door, triggering the Feed Hold input, remove the magnet, close the door, and click on OK on the popup message. Unfortunately rather than moving to the bitsetter to measure the b it length it just sits there showing Busy on Carbide Motion.

If I don’t trigger the Feed Hold by opening the door clicking OK on the popup causes the router to move and measure the bit length.

I am running the latest version of Carbide Motion for Raspberry Pi, but I have also tried running the latest windows version and it shows the same behaviour.

Can anybody recommend a way to get around this issue?

Is there away I can report this as a bug to be fixed in Carbide Motion?

The only idea I have at the moment is to disable the Bitsetter.

Thanks.

Looks like you are between a rock and a hard spot. You obviously need the door open to do a probe but with it open the machine gets confused.

Maybe you could add a relay to push to open the door for the probing that would by pass the door opening lockout but press it again after the probing is done so if during operation the machine would stop if the door is opened. It would require people to actually use it but it is a solution.
