Yes!! Honestly if the P1S was out when I ordered the X1C I would have purchased that instead. This is a conventional method that you would perform on other printers. The LIDAR sounds great and will be one day, but for now I would totally spend less money up front on the printer and tune manually

I went to a place around me that did concrete recycling and just asked if I could buy a scrap piece of marble counter! She let me have it for like 5$. Go on Facebook market place and look for like "counter scrap", "marble slab", "granite slab". You should be able to find something near you for not too expensive.

I had the same questions and, to my logic, it turned out it only makes sense if you execute a test for which you already have all known variables except the one/s you're testing. The variables of interest for the case. To me: 1- Temperature tower first. 2- Bambu tests, say PA (K value) and flowrate multiplier, in this mandatory order. 3- Max flowrate (you have to know at which temperature the material likes to run, to perform this). - Then, dimensional calibrations for shrinkage etc if needed, with a more accurate test than a 20mm cube as CNC Kitchen pointed out what I always thought. - TD if needed. I wrote "if needed" because what I've learned from this clear path evryone of us seem to crave for, is that you just have to do tests for the job you're doing and for how good you want it done. And keep in your library (drive your customer to) materials you will rebuy and you trust into. Say they will be on the shelf even the year to come. This is not only bc, you'll find, following this iter every roll you unbox makes you waste an entire morning and close to 10% of the roll you just unpacked. But mainly because as you swap object to print, color, nozzle or nozzle size, printer (in this order of likeliness) at least one of the values you found is unreliable or useless or doesn't fit the first one, the damn job to be printed. It's a useful excercise, I think. I'm still following this iter, even with discretionality (according to the job to be printed). I'm stacking the values I record for each material. But I know (...OGs told me...) that it will be my experience that will use those value without checking the sheet, not me going to read them, for the most part.

Bambu does not recommend flow cali on a textured plate tho…?

I always do the first one, the K value or pressure advance, on a smooth plate, but for the flow x or multiplier, the second one, it prints a set of tags 2mm thick to evaluate the surface so i dont think it matters which plate u use there. @@Jacksteelmachines

But even the pressure advance has a second option for the test if u check and with that also doesn't matter which plate u use. The one with the shape that resembles army badges.@@Jacksteelmachines

Temperature, estep , flow rate , pressure advance , retraction , max volumetric speed, VFA

On the way in it’s slowing down which can cause problems as much as speeding up. Although, accelerating out of a corner can drag the filament. That’s why I turn down my xy jerk.

I do PA then EM per Ellis guide linked in the description.

It's not in the "device" tab it's in the filament tab.

It's labeled as Pressure Advance, not K value, in the failament tab. What temps are you running your PEI at on what materials? I find that for best results I run my PEI pretty hot. 110 for ABS/ASA for instance. 65-70 for pla.

Very odd indeed. I’ve been using the Bambu textured PEI plate for weeks now with the stock presets on my X1-C with no issues.

I mean that’s a lot of what I said. Input shaper helps to reduce VFA by printing at a speed where your printer body is not resonating. I mention how tuning the driving of your motor is also one of the “real” ways to solve VFA, even though it might never completely go away. The combination of how your motors are driven, the belts and pulleys themselves, the inaccuracy of your filament and extruder, etc all contribute.

@@ButterPockets isnt input shaper affecting acceleration and deceleration? To my knowledge it counters ringing by counter ringing, similar to noise cancelling headphones. To be fair i haven't watched till the end, had to go outside and utilise the beautiful weather we have to do some outside work

@@kilianlindlbauer8277 it does affect acceleration and speed but you acceleration and speed affect how fast your motors turn. That turning speed of your motors causes the entire printer to vibrate/resonate/ring. This in turn is one of the causes of VFA. But all of these “artifacts” are part of the larger problem.

The OP is correct, input shaper has no effect on VFA (which is different from ringing). Ringing is caused by kinematic resonance, VFA is caused by motor resonance. If your toolhead is moving at a constant velocity, there will be no ringing (kinematic resonance), but VFA could be at it's absolute worst (motor resonance).

That would be incredible. I can ask, but I’m not sure if that will ever happen haha.

So I opened Orca slicer today and they added this in the latest Beta!

@@ButterPockets sweet! Thanks! Will need to do the update… questioning firmware but guess I’ll have to do that too.

@@cstategrad99 the new firmware is for the new version of Bambu studio. Which now stores PA k value on the printer and lets you swap profiles. Trying to do a video on it today, Bambu lab took a good step in the right direction.

It does move a little depending, but doesn't rattle. It's a really heavy shelf. And I don't think a company would let me near a printer that expensive haha, sorry!

@@ButterPockets would you share any info on your shelf? The heavy duty one I got from home Depot rattles like a baby's toy when printing PLA at optimized speed. I've been printing with petg lately with slower speeds, so it hasn't been shaking as bad.

I almost got some shelves from home depot but I ended up going with shelves from Uline. Pretty expensive, but nice. I believe mine are the 48x24x96 but they have a lot of sizes. www.uline.com/BL_3867/Wide-Span-Storage-Racks-Particle-Board

Yes, I don't know if that's worth a video, but I can write something up and post it tomorrow!

@@ButterPockets thank you! Really great video. I’ve been using the OrcaSlicer PA tests, but this one is very nice. I had wondered how to do it on an X1C. Glad I stumbled my way into your channel 😉

@@fourtwizzy kzfaq.infoUgkxVb-wiQtebhfTysgjiCKKnmpffh_DeQ-q I hope this makes sense and comment there if you want anything specific explained!

Tune PA with 2 passes. Tune EM (flow) with 1 to 2 passes. That should really be it. If you want to you can then tune max flow rate of you need to, but this is a one time kind of test per filament type - so pretty much all PLA should run at a similar max flow.

@@ButterPockets thank you for the reply :)

⁠​⁠@@ButterPockets I might say that “all of the same type of PLA from the same manufacturer has similar max flow rates” but definitely not “all PLA”. For instance, “galaxy” PLAs will be different than normal PLA which will be different from “silk PLAs” and good brands would be different than low-cost, no-names. Yesterday I watched a video from 247printing where he was running a beta PLA filament designed for max-speed printing and that stuff was crazy different. It looked like softened butter coming out of the nozzle.

that’s true. I should clarify more when I say that. You are correct that similar PLA types from the same manufacturer would be similar. I have high flow PLA from atomic and it definitely flows higher than their standard.

​@@ButterPocketsin addition, for each calibration, which automatic test does it replace ? And how often should it be done (power cycle? Weekly? Monthly?) ?

I find it difficult to print PETG over 12mm3 on any printer. Stefan shows in his video on speed vs strength that just printing faster doesn't always keep the same strength. I've found that over 12mm3 for PETG the layer adhesion is awful and the parts are weak and brittle. I'm interested to know if you experience that or not.

@@ButterPockets i just tested one of my petg cups that i printed(i wish i could post a picture of it) and a vent that i designed for myself that has some part that are as low as 2-3mm and in terms of layers adhesion and flexibility it is flawless(the brand i am using is gray petg sunlu with a cht nozzle, and it took me a couple of days maybe even more until i was able to dial it in because all the test came out fine but when i was printing sometimes i had different issues like bed adhesion warping at the bed lvl on big prints, or wall artefacts in some regions on straight line wall, or my biggest problem that i hated the most was stringing) but i have other brands that i agree that speed made them have a bad layer adhesion and some even brittle(despite me using temperatures recommended) sunlu gray petg is the only one i am able to have such a high flow and have the petg still keep it's properties. the other brands i can't get more than 26 at best and no less than 19mm3(with a rainbow petg from a brand i never heard of or used before(but again i am using an aftermarket cht nozzle that gives you about 20-25% better flow with every filament(after you dial it in)

I wouldn’t think so. I think the underlying problem is that stuff isn’t really stiff or that heavy. A stone paver or marble slab would be much better.

Can you explain what you mean? What does it do at the end?

@@ButterPockets it finish the print but after will Park the toolhead in one place and the screen will just stay with the print in progress like it is still continuing to print

It’s not really going to be different per filament. If the hotend can melt at a rate of 19mm3/s then that’s what it’s limited to. Which the hotend on the X1 is around 16-19

Yeah I’ve already had to change it once. I don’t think it NEEDs an update since you took out a lot of what changed.

I actually just ran into this myself...it definitely didn't do this before. I am working to see if I can give out a fix.

@@ButterPockets Have you figured out how to make this work with the AMS yet?

@@xThree65x they added into orca slicer by default now! So it just works :) I’m filming a video on all of the updates as I type this!
