Hello all,

Been working on my Senior Project of Water-cooling a Tool-changing 3D printer with the goal of printing HT Plastics (PEEK, PEKK, Etc.). I am using the HevORT as the "printer" and using E3D's hardware for the tool-changing operations.

I am looking for redundancy here, I want a "failsafe" for my water loop should my pump stop working. I found this "flow indicator" and from what I see, it uses a 3 pin connection, and typically plugs into a fan header on a motherboard, this makes sense to me.

Check it out HERE

My question is, how would I trigger an "E-Stop", or "Kill heat" command with this Flow meter's Tach reading "zero", which would indicate a stoppage of flow.

Let me know if you have any ideas.

Thanks in advance.

@fcwilt @engikeneer @Nuramori works great now and levels great, thank you, stuff was massively screwed up. Thank you for your help I appreciate it.

@dc42 said in Configuring 10K Water Temp. Sensor:

If it's a 10K thermistor than you need T10000 in the M308 command (assuming RRF3). The B value you need depends on the thermistor. As the temperature range of interest is low, you can use C0.

Gotcha, I just chose the 10K option in the RRF Config Tool, (which I couldn't figure out before how to get to pop up), and you can see the temperature results below.

Thanks for the help.

@phaedrux well to be honest I believe it was the M997 B1. Because I had previously been on 3.2.2 on the mainboard and did the ssh Sudo upgrade stuff in the pi and it did not change to a newer version on the mainboard. But I did do both, so I don't know with 100% certainty, apologies.
