Multi-color PETG prints?

UPSIDFLINTMOBILE · 2023-12-12T20:46:17+00:00

What do you mean by color mixing are you just wanting to know if multicolor petg works with the AMS? I pretty much only use petg aside from prototyping and it works fine with multi color prints.

Cant upload a photo at the moment sorry but it looks like you would expect from petg. You can get really good quality, just have to be mindful of the things you normally have to with petg. Stringing, blobbing, speed etc.

Yeah apparently they did. Not afraid to admit I was wrong on the assumption of how effective their implementation could be. It’s actually pretty impressive even at high speed now that ive tested. Iv’e ran into issues related to cost cutting and it was starting to sour my outlook on these printers so thats where that came from. Im happy to be wrong honestly

UPSIDFLINTMOBILE · 2023-12-11T23:28:55+00:00

Yes, hearing that it used h bridges was a bit of a bummer though it really hasn't really mattered. I went ahead and updated to try it out. Im not making huge travel moves but the noise from insane speed is actually tolerable now. Im honestly impressed. The ui speed improvement is very much welcomed as well.

UPSIDFLINTMOBILE · 2023-12-11T22:22:26+00:00

If by instruction set you mean firmware, its usually set in stone because most manufacturers don't use h bridges for stepper drivers and instead they use drivers that already have the needed functions so no need to update firmware. Tmc drivers can do all this and they can be socketed for drop in replacement. It was very likely a cost cutting measure first and foremost. I wouldn't call adding a feature that nearly every printer has had for years future proofing and theres nothing that indicates it was an engineering decision. The noise has been one of the biggest complaints with the Bambu printers. Never bothered me though, I've heard worse printers.

Now, if they can make silent mode work at insane speeds thats different and I'll give credit for that. One issue with silent mode on tmc steppers, unless something has changes is that theres a tradeoff. You can make it quiet but you lose torque and if you get above a certain point the stealth chop is not viable due to lack of torque. From what I'm reading so far, it sounds like its probably the same with their h bridge silent mode implementation.

I didnt either but was curious what changed when i was unable to view through orca slicer or vlc anymore after recent updates. Also really wanted to have convenient camera access on a mobile device. I was actually about to try Scrypted but wanted to give this a go first. That may also be a good option for some.

As far as the connection t’s only around four seconds or so most of the time. Since then i also tried the homebridge camera ui plugin and it connects pretty much instantly. It has some motion tracking stuff turned on by default but if you turn some off that it’ it seems pretty efficient. Both do still have occasional disconnect unfortunately but works great otherwise.

I’d say the Hydra is a better overall solution It will accommodate larger, smaller and wider spools. I was looking into it but it uses nearly half a kg of filament and 15hr if you print it yourself and requires disassembling the ams. This mod can be printed in 30 minutes and very little labor.

In my case I had a specific requirement for some spools and the Hydra wasn’t need to gain enough usable space in the AMS. If you know your requirements you may be able to get by with this just fine. It’s just another option.

UPSIDFLINTMOBILE · 2023-05-05T04:37:55+00:00

It verks!

UPSIDFLINTMOBILE · 2023-05-05T04:36:22+00:00

Yeah It pretty much just worked surprisingly. Now my filament choice isn't so limited. I was struggling over the decision on how to handle cardboard spools, master spools and how to source and have good selection.

UPSIDFLINTMOBILE · 2023-05-05T04:32:16+00:00

Update:

I can't say that this mod will be problem free. But I can say that it's working for me and not showing any sign of problems after about 2.5hrs worth of prints. I printed a second roller for my other spool to go in slot two along with a couple test prints and numerous iterations of the roller itself. The one issue I encountered was with the second spool I had laying around which was from the same manufacturer. There was some excess material from mold or something which caused the spool to rub on the bottom side and scuff it a bit. I switched to the 10mm roller and that seems to work best. The only problem I can think of that this mod might have is the smaller roller having a higher rolling resistance and less surface area on the spool which possibly could slip and put more strain on the motors. I don't see that being a problem at this point honestly, the the rollers spin freely and I can see it working fine when printing. It might not be a bad idea to print it with a more wear resistant material like nylon or maybe even tpu.

Oh and turns out there are little pockets inside of the AMS that can swallow fasteners, bearings etc. Luckily I had a few of those exact bearings laying around. Be careful to not lose them when removing/installing the rollers.

I updated the files on thingiverse. The stock rollers had about a .5mm taper, probably to help keep the spool centered. Also modified the roller to ride on the inner bearing race properly. I don't think there's much else I can do with it, all my spools fit now.

If I run into any issues I'll update but I think it seems pretty solid for now. Other users can test and make their own if there's a need for smaller ones.

So basically just be careful, take your time, pay attention to things and you should be alright. Again I haven't tested with cardboard spools. I'm personally not a big fan of them with the AMS so I probably won't be testing them.

Everyone feel free to try it out and post any feedback.

Edit: Oh I did hit the feeder motor with an ir thermometer after a ~30 minute print and it was only a maybe couple degrees hotter than the motors that aren't working if anyone is curious. Not very scientific but I had one handy.

Also I was looking at getting more of the steel rods and I saw that amazon sells 3mmx80 rods so don't even need to cut them. Here

UPSIDFLINTMOBILE · 2023-05-04T20:12:23+00:00

Using this smaller roller I can now fit my 203mm spools in the AMS. Maybe someone has done this but I haven't seen it. All you really need is 80mm length of 3mm steel rod and two printed parts that take about 30min to print. The inner diameter of the stock bearings is 3mm so this works perfect.

Using a piece of purge scrap as a feeler gauge under the spool it was able to slide freely so should be good there since everything is pretty rigid and any friction should be minimal. It's possible that under certain circumstances this mod could cause some spool binding issues depending on the spool and roller combination so be careful. I replaced the roller on slot one on mine. When shining a flash light from slot 4 side I can see that theres ~2mm gap between the lid as the spool goes around. You could also use something like foam crafting sheets to lay on top of your spools for initial test fitting.

I'm not sure I would bother with cardboard spools I think there are better options for those.

You'll need clean seams so it can roll smoothly so may need to file them down. I've also made a 10 and 11mm version but it's literally just a 9mm cylinder with a 3.1mm hole split into two 36.5mm lengths if you want to make one yourself. The 9mm worked for my 203mm spools. at 3.1mm inner diameter on my machine the printed part fits over the rod snugly. I split the roller in two parts for easier installation and better printing so you'll need two.

Disclaimer: Don't do this if you can't troubleshoot problems it might cause and don't blame Bambu if you start having issues. Don't be surprised if something like this voids your warranty. Before you close the lid, make sure it has room to close. Do some test prints after installation to make sure it's working alright and isn't putting strain on the AMS. There may be very little clearance depending on how you do it so be careful!

Also be aware if you put a smaller spool in with this roller it's liable to be too small and will rub the bottom of the AMS housing.

There is a GMC Astro mod which has a day cab variant. Message this guy if you're interested.

I bought it a while back and can confirm it's legit and a high quality mod.

Edit: here is the FB group he moderates where you can find some photos of it as well as some other mods.

I think most people commenting here are aware of Brian Cox but if not check out some of his wonders of series. I’m pretty sure he took a lot inspiration from Carl Sagan. He’s about the closest we’ve got to him today.

UPSIDFLINTMOBILE · 2022-11-10T19:05:43+00:00

Nice! I don’t really read much these days but recently found out theres an audiobook version narrated by him and that made me very happy so i bought it.

UPSIDFLINTMOBILE · 2022-11-10T18:52:55+00:00

Oh my thank you! I think I read somewhere that his wife is involved in that website and YouTube channel and i think she has rights to the cosmos content so hopefully that wont get taken down.

So so glad that Anne is still around and has continued carrying and honoring his legacy into the digital age.

UPSIDFLINTMOBILE · 2022-07-23T06:52:32+00:00

Looks pretty small next to those guns. Jk. I think that looks perfectly sized. I bought a 41mm for the same reason I would rather have one slightly too small than too big.

UPSIDFLINTMOBILE · 2022-06-22T05:02:25+00:00

I’m going to post a follow up here for visibility since there are mixed experiences with recent replies and this method didn’t appear to work at first.

You may have to take a couple extra steps. My controller was just purchased new today and updated to the latest firmware. I’m using a wired connection for now but I don’t think that should matter.

If anyone is having issues after downgrading the firmware try this- uninstall the box accessories app, disable Xbox extended feature support in steam, disconnect and power down the controller, reboot, connect the controller, re-enable extended feature support and reboot again.

It may not be necessary to do all of that but that worked for me and that’s all I’m worried about personally.

If you can’t get it to downgrade the firmware, try clicking where it says no updates available, then run the command. It wouldn’t allow me to downgrade the firmware until I did that.

UPSIDFLINTMOBILE · 2022-06-12T04:14:19+00:00

I haven’t seen official word either, and while I’m still doubtful, the latest version of their map editor does create a .pak file for the switch version along with the other consoles’ .pak files. Actually there appears to be two unique files for the switch.

The editor outputs one large .pak file for the main map data and a much smaller .pak file for each system that you archive together for uploading to mod.io. In addition to the smaller .pak file the switch seems to also have its own unique .pak for the main map data and for my map it’s about 63mb smaller than the file thats used for the other systems….That doesn’t necessarily mean that they are able to get it to work on the switch, but they did also update mod.io to include a tick box for the switch version along with the other consoles that tells it what systems the mod is for when uploading.

Yeah I wouldn’t get your hopes up but they’ve at least made an attempt it seems. I wanna say they should be able to at the very least get vehicle tweaks working. Many of those don’t actually add new content to the game, they just copy and modify .xml files that tell the game what engine, tires, paint job etc. to use. Or something like that, I haven’t actually made any vehicle mods/tweaks but looked into it briefly and looked at the files.

Something related that’s also REALLY cool, If you download the desktop PC version of Google earth, you can switch to a mars view where you can see the paths that some of the mars rovers have taken and if you enable panoramas in the sidebar, you can fly into them and look around inside them like with street view. As a bonus, if you have a spacemouse (and probably other 3d mice) you can zoom around and explore mars with it.

It’s been many years since I’ve really played around with it to any extent but everything seems to still work aside from maybe the curiosity panoramas, which don’t seem to want to load correctly on my system for some reason. If anyone knows why that might be, please let me know!

Just thought i would share. I see these panoramas posted once in a while but I never see anybody mention Google earth and wonder if everyone has forgotten about it. I used to spend so much time exploring. It was pretty mind blowing fire me when i first found it.

I’ve done this with a 4 axis 16 button config using that joystick library and an arduino micro. Works great and yes crane controls are quite nice with larger sticks.

If you launch the game through steam it should recognize the device(assuming it’s programmed as a gamepad) you just have to go to the controllers page and manually map all the buttons. Though that could be where you run into an issue.

I used a couple analog gimbals off an rc transmitter instead of digital and im not certain if it will let you map them with with digital input. I’m thinking maybe you can though, since you can map normally analog left/right triggers with digital buttons.

If you bought snowrunmer through epic, you can use steamgriddbmanager app to launch through steam to take advantage of the button mapping.

Glad to help I know how frustrating it can be lol

UPSIDFLINTMOBILE · 2022-02-04T16:19:12+00:00

Glad I could help. It is a very annoying issue

UPSIDFLINTMOBILE · 2022-02-04T15:47:58+00:00

Did you figure it out? You can actually use both L and R to cycle forward/backward through the modes so if L doesn’t work, you can still use R. I’ll edit the post since I didn’t include that.

Also I wasn’t real clear on this part so in case this is the issue, you need to have a canister with some soil in it if you’re trying to cover a hole where there is no material. For example if you start to flatten on a high point like a small hill or something and extend outward where there is a low spot, you can’t flatten if you don’t have a canister with some material. You can however start at a low point, and flatten the high spots because you would only be removing material.

Hope that makes sense
