Bianca v3 delay before low flow starts (also PID variable link pls)

tobyjrn6

I recently moved and took it as an opportunity to to have a bit of a fiddle with my Bianca which has been on a bit of an autopilot for the last year or so.

I have noticed:

I appear to have quite a bit of burn in on the screen of the LCC now that I see it in more natural light - this appeared to manifest after i did a factory reset but there’s a good chance I’m imagining that and it’s been there for ages.
More importantly - my low flow start setting only kicks in after the pump has been on for ~3 seconds. I am 99% sure this isnt expected or previous behaviour. I wanted to check if anyone has run into this and potentially how to resolve it. I find it strange this would just happen randomly and be so reliably repeatable. It could well be that im missing something stupid and obvious!
Aside: does anyone (possibly the man himself @DavecUK ?) have a link to a resource with all optimal PID configuration variables. I have found most of them from a previous post but for example cannot for the life of me find a value for KIc

Thank you in advance for any help!

Little bump to see if anyone can solve or has encountered my low flow issue?

Hey - I don’t have a Bianca, but these are my 2 cents…

1) burn in: unlikely. I have an Elizabeth and it has the same display. There’s no way a factory reset can cause burn in to the display. Do you leave the machine on all day or for long periods? Does a screen saver kicks in after a while?

2) low flow… I can’t see a problem. The low flow solenoid kicks in after 10 seconds which is how you programmed it. You can see the flow speeding up after 10 seconds.

3) ~~that setting is on this forum somewhere, I remember seeing. You’ll have to do some digging I’m afraid~~.

From the post you referenced above - looks like the OP quoted what could be changed from factory, rather than everything?

More importantly, if you are happy with the temperatures/recovery, maybe there isn’t much to change? I really don’t know.

MediumRoastSteam if you watch and listen out, the flow starts at regular speed for the first 3 seconds and then low flow kicks in audibly. I know that it picks back up at 10s as programmed, but if for example i wanted a 3s low flow, i never get low flow haha

On 1, yeah i leave it on all day, i think just burn in tbh.

I’ll have a further dig for the PID parameter

tobyjrn6 - now that you pointed it out, I can hear it. But it’s very faint in comparison to the one at 10s.

Is there a setting maybe in the advanced settings where those 3s can be configured?

What pre-infusion settings do you have?
