Tweak 5: Installing Filter Capacitors

Continuation: The Professional Upgrade (Panasonic-GX-H12A)

Z-Offset - Master Roadmap

Hi Johannes, I am doing some lot's of testing, now on my Voron printer and found something very interesting: The Baolsen sensor performs quite well there. Also noise levels. But in my Voron the tool-head is an Umbilical setup, which means that cabling are minimal, since a dedicated MCU board is mounted on the tool-head. Also precision is quite good. So the main issue in Artillery has to do with the longer cabling and too high pull-up resistor. So I would bet that adding a 4k7 1/4W resistor between...

Yes maybe a bigger fan will reduce noise. The factory default is quite loud.

Just search GX-H12A on these pages. They are too dynamic and will change constantly.

Consider your mechanic. I've added an anti-backslash lead, like this: https://de.aliexpress.com/item/1005004293808084.html (the 8mm Round Brass variant).

While in my graph, it's around 0.4mm. That tells me there must be something wrong with my setup, probably the probe has...
