BLTouch with LDO Nighthawk SB?

[kharrisma]

Hey Forum Folke,

Nearing completion of my switch from a Hero Me printhead to the Voron Stealthburner.  Currrent ABL probe is a BLTouch, which as likely everyone here knows is a five-wire device: three servo, and two for the actual Z limit 'switch.'  Rather than re-inventing the wheel, I thought I'd check and see if anyone here has successfully managed to get a BLTouch to work with the LDO Nitehawk SB.  Obviously not going to be a straight plug-in and go; looks like some remapping of GPIO pins is going to be involved... more new territory for me    Any ideas appreciated!

Just came across this & wondered how you did. I setup a Nitehawk-36 on a Mercury conversion for Ender 5+. I couldn't find an easy way to map the BLT signals, so I ran a composite cable along with the USB connection. The BLT uses a few mAmp so my cable is a 3-conductor 26ga affair that's tied to the Nitehawk cable. Power comes from the empty socket on the Nitehawk. I know.... Kinda defeats the purpose of the conversion in the first place, but it was simple and works, and the cable has minimal mass and is very flexible. Sorry, best I can offer

Worth knowing, Matty... thanks for the reply.  Gave it up as being more effort that it's worth, and opted to go with the Voron recommended Omron inductive sensor instead.  Haven't been able to actually *use* the thing yet, as I'm fighting with unrecognized thermistor types and out-of-range temp readings that won't let me do anything with the machine yet.  Thought I was making things more simple by adding an [include nitehawk-sb.cfg] at the beginning of my printer.cfg, but then there arises the issue of duplicate entries for some things, and where to leave them and where to delete the dupes.  Klipper doesn't specify *which*   *.cfg file the error is in; sometimes if's obvious, others it isn't.  Right now I can't get past the (heat block) thermistor issue no matter which file I put it in.  Standare V6 thermistor, but it's reading 4.4 MEG ohms at room temp (around 18C)  That ain't right by a long shot.  Ordered a PT1000 and we'll see how things progress after that.  THEN I can get back to the ABL sensor issue.  Not giving up in the BLTouch just yet, but in order to get it running, I'll switch to something I know works with the Nitehawk.  If I do manage to make it work, I'll post what I did here.
