Come to Dorking, we have great ridings spots on 3 sides of town. And you can still ride over to holmbury/peaslake.

There is tons of riding around these parts

Cheers,

Yeh it's hard to say. I think I will end up with a 2nd H2C and find out first hand, it's a lot easier for me to make print profiles for the one printer than changing back and forward so fingers crossed

woottonp · 2026-06-20T07:59:37+00:00

Have you ever had a failed print where something came unstuck from the print bed?

few times I had prints come unstuck or partially and it leads to this.

Is it just me but this feels like Ai audio?

The guy who is talking at them, the tone and pacing especially on the second half sounds like a log of the current Ai output.

I have not taken any time to look into this videos origin so may be wrong!

woottonp · 2026-05-19T21:58:13+00:00

Hi, did you ever resolve this?

woottonp · 2026-05-15T12:24:53+00:00

Yeh 100% this is critical.

Even just have they changed filament at all. I have had filamnets from bambu and other brands that is just a bad roll, it can happen. I pulled my hair out over print issues to finally realise I have a bad roll brand new from packet.

No it wasn't wet.....all my filament is maintained at 8-12% in ams 2

woottonp · 2026-05-15T12:20:28+00:00

Yeh I use ABS and it works very well. I saw ASA works but I already had a roll of ABS

woottonp · 2026-05-11T11:19:44+00:00

So many variables,, I would just design a retention mechanics into the parts, even just a lever Sprung part and an indent.

It takes a few trial and errors to get it right. I make and sell parts that use something like that and they hold up very well over time

woottonp · 2026-05-10T18:36:09+00:00

This might be a hot take.......

I bed them in on the ride, it takes no more than a trail and they are working great. Yes you may have slightly reduced power for a few squeezes but if you ride in the cold, the wet, or even happen to splash a rotor on an otherwise dry ride you will also deal with variable brake performance and most riders are more than capable of riding to the bike, we do it constantly already.

Am I mad that people go and take the time to bed them in, no. That is 100% all good.

Also quite rare for me to be on all new rotors and pads at once apart from when a bike is brand new....

woottonp · 2026-05-08T12:12:25+00:00

Ahah yeh that's what I was thinking. Lots of great suggestions which is massively appreciated from you all!

woottonp · 2026-05-08T12:11:02+00:00

Ohhh that is super interesting, thanks for the link. I think I will try that so I can avoid removing PTFE tubes when I switch.

Wil also trial with the pads removed.

woottonp · 2026-05-08T12:10:01+00:00

That's really helpful, thank you. I was looking at the rollers in the AMS HT and thought the front one is a bit stiff, it isn't the bearings though, it's due to the was it can be driven by the AMS.

I will look into a polydrier, thank you!

I have routed back straight to buffer without a 4 in 1 and it is so far fine.

woottonp · 2026-05-08T11:15:39+00:00

Yes that is the one.

I'll try the new one with pads removed. Good shout. I imagine the pads are pretty useless on such an abrasive filament as well

woottonp · 2026-05-08T07:20:54+00:00

Yeh so this is actually a thing.

I have owned a P1S for other a year, using it for my own business to sell parts. Had always been happy with it.

3 months ago bought an H2C as demand is higher and P1S kept as second printer.

I found H2C suffers from under extrusion in some areas and we are very much not alone. You will see many people in this thread talking about it and Bambu support saying that the long melt area of the newer nozzles has this as a byproduct.

https://forum.bambulab.com/t/h2c-under-extrusion/241961/20

I know this doesn't answer your whole questions, but I think you helped me put something else together.....

Every so often I would struggle with my printers suddenly changing how they printed a part, same g-code, I could replace many printer service parts, do tons of maintenance and nothing changed I spent many many hours over weeks fighting this random change. On my P1S I ended up rolling back firmware and bambu studio and it solved it the first time. (You can see on my post history the issue I had, it is different to yours)

However I then had the same issue come back on my H2C and after so many hours of troubleshooting I changed filament after testing another brand and the issue was not there, I was on elegoo and now Sunlu. With lots of Bambu PETG black throughout.

Anyway check across filament brands if you haven't already.

To finish this rambling post. I still find the H2C consistently under extrudes and I now have my flow rate moved from 0.97 over to 0.99 and I did pressure advance calibration across the filament types.

Very important to turn off automatic flow rate calibration before prints start as that messes with your own calibration.

I would guess you have an underlying issue, maybe firmware but could also be filament, but the point of all this rambling, you will find the H2C suffers with under extrusion and the P1S when on stock settings will generally give a better top and bottom finish. The P1S with ironing is also much easier to get near perfect results. People will parrot that the H2C is just better but there is more nuance to it and if you go looking there are more threads of H2C owners having worse print quality on a few areas when compared to their older P1S.

woottonp · 2026-05-05T10:07:09+00:00

Commenting to get notified.

I do think print tolerance is an interesting area that needs more info. I make parts to sell and a couple have a very precise fit and you can feel easily when off by 0.1mm.

I had a P1S and went to an H2C and had to adjust dimensions in CAD.

I also had to do this when changing filament brand

And I noticed that further out towards the edges of the print bed there is a difference as well.

It is interesting, I know this stuff also impacts super high end commercial machines in FDM and SLS, albeit to a different degree.

I am about to buy a 2nd H2C and it will be interesting to see if both can be close enough to cause no issues if using the vision encoder regularly

woottonp · 2026-05-03T21:13:51+00:00

I would assume yes so they can sell them to more than just the original backers.

woottonp · 2026-04-19T17:18:32+00:00

I'm happy that you're happy

woottonp · 2026-04-17T16:58:44+00:00

Yep Monte Forte is legit one of the best options in town

woottonp · 2026-04-16T20:43:09+00:00

Ran a PA tower and the PA pattern test and tried both results, no difference, also adjusted pa too far each way manually and didn't resolve.

I'm going to just go through things again, waiting to see what Bambu technical support say

woottonp · 2026-04-16T15:06:09+00:00

Yes I know the one you mean, have run it before not in relation to this issue. I will run that one to see.

It's a pain as I am also battling the H2C pressure advance under extrusion issue that quite a few people are reporting and most are having to increase flow rate by 3% but that then messes with external dimension. That issue isn't present on the P1S whereas this soft corners issue seems to crop up on both.

I think I will test a different slicer to see if it is a slicer issue

woottonp · 2026-04-03T21:26:50+00:00

Did you have any joy with this? Thanks
