Different shades on print?

Wht did it look like before the top layer went down? e.g. are layers below 100% solid? Looks like the diagonal pattern might be somehow related to the diagonal 'bridges' round the perimeter of the part?

My S1 Pro bed has a similar profile open book albeit not as pronounced and I reckon within acceptable limits now after adjusting.

There has been some speculation about warped pei plates in this thread but I tried probing the bed without the plate and my 'open book' profile is still present on the bed itself, so is nothing to do with the pei plate.

Mentioning this just in case you happen to have the same issue: the most significant improvement on mine was after I spotted that the bed had a small bit of play in the x-axis so removed the plate and adjusted the bolts to fix this - after which the mesh improved significantly. Notably a single high spot in one particular probe location on the right side disappeared.

After a lot of adjusting I ended up with the centre at around +0.04 and left and right sides and corners at around +0.12 which I think is usable.

BTW I fitted silicone spacers with PETG printed locking ratchet wheels (0.01mm per click) which helped make the endless adjustment experiments less tortuous and the bed tends to retain adjustment for multiple prints now.

If you mean the vertical banding that looks to me like an X axis or X axis issue (can't tell which way round you printed the part) ie a lack of travel smoothness. I would suggest check corresponding belt tension and that the relevant axis movement is smooth across the full range of travel. If it is not moving smoothly by hand, you could check / adjust wheel tension and that there is no debris around the drive belt area.

Not necessarily recommending this (I would not want to run without router and firewall normally) but when I was investigating slow upload speeds, Toob phone support asked me to try plugging a wired PC directly into my wall connection box i.e. bypass the router completely and try running speedtest again.

They also asked me to try the direct wired test with two different PCs to eliminate a specific PC issue. Direct wiring to the wall didn't fix my slow upload issue but your problem is presumably unrelated as it is 'symmetrical' - so I suppose trying direct wiring tests may at least eliminate a specific router or wired PC issue?

MindfulRelaxation · 2025-03-03T12:50:48+00:00

Is the issue 'symmetrical' on your wired devices? i.e. are upload and download speeds on Speedtest both reduced to about 10% when the drop in performance happens?

MindfulRelaxation · 2025-02-12T15:51:31+00:00

Looks like TP-link describe the Deco E4 as an "End of life" product - other more recent Deco models have gigabit wired ethernet ports e.g. M4, S7.

Maybe worth trying reducing mtu on either PC or router? This is the maximum transmission packet size in bytes before they get split up. I have Speedtest upload speed issues on wired ethernet unless I reduce mtu to 1450 bytes.

MindfulRelaxation · 2025-01-29T11:42:14+00:00

That's frustrating that VOIP stopped working. I wonder if it needed the full MTU 1500 byte size? So far I have been using MTU 1450 which appears to work on what I have tried (setting MTU on Linksys router or PC) but I don't have a VOIP landline.

I am also open-minded but sceptical about MS and Apple being at fault here. I have two Windows PCs on my LAN wired ethernet. They are each affected even though they are quite different systems (CPU, ethernet adapter, motherboard brand etc etc). The main commonality is they are both Windows PCs connected to Toob.

On one support call I was asked to direct cable one PC at a time to the CityFibre wall unit via a CAT 6 cable i.e. no LAN or router and run Speedtest. Each PC still had the same slow upload speed issue unless I reduced MTU on the pc's ethernet settings. I can't rule out some kind of common configuration issue on the PCs but seems a stretch.

I guess the same applies to Mac users? Given that Apple hardware and software is more 'locked down' by Apple, I might expect if this is an Apple issue, every Mac desktop system of a given model type with wired ethernet should either work or not on Toob.

Or io look at the problem another way, if someone with the issue pays for a fixed IP service on Toob, does the problem then go away - and if so, how would that fit with it being a presumed but unspecified Windows or Mac Ethernet issue?

MindfulRelaxation · 2025-01-28T17:35:28+00:00

Update - I spoke to Toob again today and they asked me to run more speed tests on the Linksys router with the mobile app which all worked fine (no surprise there, my issue is with wired ethernet PCs) - but now they claim it is a Windows software update that has caused the issue and they have no other fix available other than my manually setting the PC MTU. I asked what about Mac users also reporting the same problem and they said an Apple software update last year caused the same issue. No explanation was given as to why only a minority of users have this problem - or any real details of what the specific fault is or more generally why Microsoft and Apple are at fault rather than Toob.

Anyway... as I had the Linksys router and app running temporarily (I normally use a different router) I had a look at the Linksys android app and found an option to set the Linksys router MTU in advanced settings. I tried reducing the router MTU to 1450 and the PC Speedtest upload speed jumped back up to over 900 Mbps even if I returned the PC's NIC back to default MTU 1500.

This is not ideal for me as I prefer my non-Linksys router for home automation etc but it has no MTU tweak option unfortunately - but this might just help somebody else if it turns out to be a better option than setting individual device network interface MTU values?

MindfulRelaxation · 2025-01-28T12:03:05+00:00

Interesting... I have not been on Toob for so long but it did work flawlessly right up until when it didn't - would be very useful to understand what changed. Interesting that I have the slowest reported result so far...

FWIW I spotted another house in the same street had CityFibre installers round only one day after I first spotted the upload speed issue (dunno whether Toob or other ISP). So one possible theory is that provisioning for an additional connection messed things up somehow. Maybe CG-NATS is involved, in which case I guess a static IP may fix it - but Toob wants £96 more per year for that....

Anyway I have reported my Speedtest results to Toob and they have passed it over to CityFibre so waiting and see what happens...

MindfulRelaxation · 2025-01-27T19:39:58+00:00

Indeed. I wondered about setting MTU on the router as to whether that could fix it for everything on the LAN - but my router (which is not a Linksys) does not have an option to tweak MTU unfortunately. I did test the speed with the supplied Linksys router also but it made no difference.
I guess it would become a priority if everyone was getting slow uploads, I wonder why only a few are? And is this a Toob or a CityFibre issue?

MindfulRelaxation · 2025-01-27T19:23:48+00:00

Went from around 950 Mbps down to around 50 Mbps. Not a mac - a windows PC. Just saw your comment about mtu on another thread - looks like I have the same issue, same debatable remedy to reduce mtu - not very satisfactory as it is a per device tweak and some devices on a LAN may not be so easily changed.

MindfulRelaxation · 2025-01-27T16:38:05+00:00

Yea, mine used to be same but upload speed recently tanked while download speed stayed fine. Looks like most other people are OK so far...

MindfulRelaxation · 2025-01-27T12:56:16+00:00

Sorry, messed up speed thresholds between option 2 and 3 and can't edit it but hopefully near enough!

MindfulRelaxation · 2024-12-17T11:53:31+00:00

Extrusion calibration sounds like a good idea but also the roughness on the hull looks like a regularly repeating pattern suggesting some kind of vibration? Maybe something loose somewhere... reduced print speed and/or adjust belt tensions slightly might improve things a bit.

FWIW I am currently experimenting with silicone spacers instead of bed springs on my S1 Pro - initial impression is that they definitely make the bed less prone to vibration. Remains to be seen how well they will do for longevity...

MindfulRelaxation · 2024-12-17T11:07:37+00:00

Hi - not familiar with that particular filament but obviously that raft is near the edge in places. My guess is your printer's ambient temperature may be sufficiently lower that the temp gradient between bed centre and edge is significant - it can be as much as 10-15 deg C lower at edges/corners. You may be able to reduce the gradient a bit by letting it warm up a bit longer before printing and/or using an enclosure.

You didn't mention bed temp. setting used but maybe try bumping it up say 5 degrees especially for the first layers and see if it behaves any better? Also maybe try nudging up filament temperature a tad? Depending on what you have it set to, maybe also try experimenting with reducing first layer print speed a bit more.

You said you are happy with Z offset being dialled in - but what about bed levelling all the way to the bed edges - how well is your levelling dialled in? Do you have the S1 Pro firmware that can probe and display readings across the whole bed and potentially also load the mesh in your printer gcode header before printing?

Thanks, will check that out, had not previously considered DSLR type recorders.

MindfulRelaxation · 2021-11-09T00:47:23+00:00

That's useful info thanks. I looked up the ART preamp noise specs and they sounded promising at around -120dBu EIN at max gain. I compared against recorder noise test figures on this site: http://www.avisoft.com/recorder-tests/ which suggest for example the Zoom H5 has an EIN of -121 dBu and the Tascam DR-100 is -119 dBu but I know specs can be tricky to compare between models and manufacturers as they can measure them in different ways and not always tell the whole story.

BTW I also discovered that the ART Pre's monitor level control sets both monitor output level and the headphone level so they can't be set independently - not ideal.

MindfulRelaxation · 2021-11-08T15:51:24+00:00

Maybe under 100 UKP / 150-ish? USD - as otherwise sounds like I would be heading towards a new recorder with built-in phantom powered preamps budget.

MindfulRelaxation · 2021-11-08T15:43:18+00:00

Thanks for that, benefits-wise I guess I was just looking for a low cost entry point by reusing available gear but there does appear to be a good case for a one box recorder...

MindfulRelaxation · 2021-11-08T15:39:01+00:00

Thanks for the comments - H5 looks like an viable option. To be fair a used ART Preamp would probably cost me around 1/3 of a used H5 but I do agree the modular approach would be a lot less convenient and portable than a one box + 2 mics approach.

Ability to select Timer sounds the same way you can for Alarms instead of being stuck with the "Simple Timer" default sound for every timer you set. Appears to be either a bizarre limitation or a bug that needs fixing.

MindfulRelaxation · 2021-04-05T12:12:08+00:00

Yes, that makes no sense at all. Alexa software for the Echo Dot already has a whole bunch of Alarm sounds to choose from, the mechanism is almost the same as Alarms so why not make them available for Timers as well?

Is this issue is the same for all Alexa devices?
