PINDA adjustment

Hello All,

I find myself having to use a -.95 z adjust to get a good adhesion to the print bed. I know I need to adjust the PINDA , but I just want to make sure I am thinking correctly. I should raise the PINDA some correct? All this lowering and raising is getting my brain to hurt 🙂

Thanks

Dude tell me about it... 😯

In the preflight check Josef says to line it up with the cable management holster

I did this and it worked. But I will say the nozzle absolutely touched the bed during calibration on the point in the far right back. I had to fuss with some things to fix it, now my first layer is too thick but I don't care. I am terrified of scratching the bed.

Yes, you need to raise the probe - do that 1/6 th turn at a time, but don't forget to reset the live Z adjust before you move the probe...

You can get a good idea of when the probe is adjusted about right:

Auto Home
Slide 3 layers of copier paper under the nozzle; if it's loose then raise Z, raise probe and repeat
It it's tight, raise Z, lower probe and repeat
It it slides with a light friction, then it's about correct. Live z adjust will be about -0.15mm

Well I think I scratched my print bed in my attempt to correct this. 🙁 I am starting to wonder why I bought an assembled printer instead of the kit as much calibrating as I have had to do.

Re: PINDA adjustment

I am so sorry to hear that. I powered down my printer mid calibration twice because I was afraid it was going to touch. You just never know.

I wonder how hard it would be to mod the nozzle itself so that it can detect when it touches the bed. Make the whole thing an induction sensor?

Yes well this whole experience has been trying for me. The box was dropped by UPS so it came with the heat bed detached. I found a local print shop to print out the bracket on the bottom of the heat bed so I could reassemble it. Ran ok for a couple of days, but then I got a huge blob of PLA built up around the extruder. Disassembled it to clean it and noticed that the extruder fan was missing a blade so bought a new one. After cleaning it I fought to get the live z setup. Now I finally got the live z making good lines with the V2callibration. Yay. nope. Now after 4-5 layers the filament gets jammed and stops coming out of the extruder. I think there might still be some of the PLA stuck in it somewhere. So back to ordering parts. I ordered a new extruder kit so once that gets here I will have to disassemble it again. I bought it assembled to try and avoid all of this. 🙁
