@Dakota Bambu uses piezo under bed sensors.

@Dakota What I did a while ago when I was faced the same issue is :

To feed 3.3V (or whatever voltage is safe for your GPIO pin to set it to TRUE state) on the pin number 22 on the connector Run gpioget in a loop to all the pins and store the ones that reports 1 Connect the pin number 22 to GND Run gpioget in a loop to all the pins again and store the ones that reports 0 Make an intersection on the results from #2 and 3#

If you are lucky, you get only one result but if not, it should reduce the number of potential candidates pins.

However, be careful because there is some pins driven by the system so they can get a random state when you poll them.

Ok I’ll contact my reseller. The thing I’m worried of is this is the second sensor I’ve had to buy for them. I’m really hoping third time’s the charm…

@Dakota Interested in this topic!

@dc42

Ah I see… well in that case I’ll lower the current on them. I hadn’t installed active cooling over them but their typical working environment outside of the enclosure on the back panel is 15 - 20 degrees Celsius. Either way thanks for the clarification and I’ll lower the working current.

@dc42 thanks for the response, I hadn't even considered that possibility, but given your expertise is much greater than mine and the logic sounds reasonable, I'll be sure to implement that into the Hotend assembly to protect it.

I do still have questions as to what the driver 4 reporting a high temperature issue. do you think that the event of the filament sensor getting excess static charge began affecting the the stepper motor driver? The wiring for the stepper motor (x axis in this case) wasn't in the same wire loom so I would assume the only point of contact could be on the board side.

As for the filament sensor, I did find the portion in the documentation and it say there is a 12c communication error. Me being a mechanical engineer, I'm very fresh in the data communication and coding aspects of engineering so I'm not privy to knowing how to solve an issue like that, nor did I find that information under the troubleshooting tab. Is it possible the static discharge could have affected the filament sensor as well?

There is work planned to add a gcode that handles heater functions directly. The way it was back in the day was too rigid and the way it is now still doesn't cover all the desired functionality.

@Dougal1957 said in More info regarding zesty tech nimble v1:

@fcwilt yes if the ripple is in an upward direction reduce steps or flow and vice versa

Thanks.

I assume by ripple you mean the faint "sloped" pattern that appears on some prints?

I will try your suggestions although that artifact has never troubled me. I only print functional parts where appearance is of little import.

Seems like most of you have a very high pressure advance. I run a Zesty Nimble on a Hypercube Evolution with a 0.6 mm E3D Volcano hotend. Sweet spot seems to be somewhere around 0.01-0.03 depending on how flexible the filament is.

I usually run 2 mm retraction at 40 mm/s, seems to work good for the Volcano.

I created this script to generate test files for pressure advance calibration if you would like to try:
