Initial beacon calibration fails constantly...

[balmy elm]

I´m now trying since some hours with calibrating my beacon h.
I don´t get something.
Beacon screws are tight...
I don´t know how to get this beast working on my VC4/300.
Any help is appreciated.

The same beacon was fine on my VC3,

did you check to make sure the leadscrews and clamps are all tight?

also is everything upgraded in RatOS to the latest version?

[balmy elm]

Leadscrews and clamps are tight, RatOS is up2date.

[honest gale]

is the nozzle clean. Like spotless with no filament loaded? Just making sure something is not hitting the bed before the nozzle

[balmy elm]

There is no filament loaded, the nozzle is clean and new. May be one z-motor can make some bs here? I don´t know... Before I change the motors I need to be at least sure...

[honest gale]

what step are you on in the beacon calibration that is causing that error?

also are you in performance mode? I dont think it makes a difference for this error but if you are comfortable your basic motions are working enable it in the configurator

[balmy elm]

It already fails at collecting samples. My printer is set up in performance mode, but I don´t think that this is the issue here.

@balmy elm could you try this ? #ratos-development message

There was in issue where the default non-performance mode z accel was too low for beacon to properly register. If you have performance mode enabled that's not an issue. I also fixed the non-performance mode accel a few days ago so it should work consistently now.

Check your nozzle is hottightened etc etc.

I tested the settings now...

I even don´t get that far to heat up the nozzle. The initial sample collection is failing.
I just dismounted the complete hotend and assembled it again. Checked all screws at the bed and all other stuff.
What I can say is, that I have 3x** ldo-42sth47-2504ac** on z, overtaken from my VC3.

[honest gale]

do you mean the ldo-42sth48-2504ac? I am not familiar with the 47

[balmy elm]

The 47 is most probably identical to the 48. Has been sold by RatRig in the past together with their VCore3 printers.

[honest gale]

ahh. a quick google came up mostly with 48s

just wondering if the rotation distance was different

you using the stock vc4 lead screws or reusing vc3 ones?

I dont remember if they are different or not

[lapis sphinx]

Yeah this is most likely mechanical issues, z or toolhead.

Also make sure you beacon is mounted parallel to the bed, i've seen some macguyvered setups that had it at a slight angle, which doesn't work well.

[balmy elm]

I bought the hardware kit which includes the lead screws.
The 47s are identical to the 48s. They have the same rotation distance and amperage. I even don´t know why RatRig had them named 47 instead of 48.

[balmy elm]

I made sure that the beacon is mounted properly, because I thought that that would be important.
Leaving the motors on z in question...

I still have some identical spare ones, so I first will exchange them.

[balmy elm]

Well... let me say it in my words...

If your z-hight bumper are not mounted high enough, beacon is not even able to measure something useful...

I´m now feeling like an absolute noob... 🙈

Glad you found the problem
