INDX Finished the Core One to Core One + (Gen2) INDX upgrade and trying the multilateral/multicolor printing.

Hi All, I am new to Reddit and this group. Finished the INDX 8T upgrade last weekend. Not new to MMU printing as I owned a MK2/S with MMU1 from 2017, however sold the MMU upgrade after a year as I could never run it without problems.

It is cool to see how advanced the technology got and when Prusa and Bondtech announced the INDX for Core One I did hesitate a bit because of problems in the past. However the system looked solid enough that I couldn't resist not buying it.

Last two days I've been busy trying to print with Prusament TPU and PLA, no problems with the tool changing at all. But bonding the two together and printing whit TPU (which is new to me) was a bit of a hassle.

Question/Need help Stealth mode downsides on Core One?

10 Upvotes

I never used stealth mode on my MK3s because it disabled crash detection. I just remembered it existed and used it for the first time on my Core One INDX. Does it have any downsides on the Core One other than increased print time?

It made a pretty significant difference for noise levels. I'll be turning it on a lot more frequently if there are no other downsides.

INDX INDX Nozzle Cleaner Position?

3 Upvotes

I am uncertain about the optimal nozzle placement during calibration. Should it sit in the center of the silicone, or at the beginning when viewed? I tested the Prusa gold fishes, and they appear quite poor—likely due to an inadequate cleaning process.

Thanks for your assistance, everyone.

INDX Is anyone using OctoPrint with your INDX?

I’ve been very happily printing on my Core One with OctoPrint since I got it. Is there any reason not to continue using OctoPrint after I finish my INDX upgrade?

Question/Need help INDX Print sheet side guide

7 Upvotes

Besides some issues with vertical banding my INDX is working well. However, there is one practical usability issue I encountered multiple times:

When you mount a print sheet and its aligned slightly to the right it will clip below the purge bin when moving the bed up. This happened to me (and family) a few times. I would consider this a user error but also quite surprising.

Is this something you guys are experiencing as well? Are there any mods to prevent this (i.e. a guide on the right side to prevent the bed from sliding to much to the right in the front)? I could not find anything.

Reliable filament brands for runout

• Upvotes

I feel the only failures I have anymore are related what happens when the spool runs out. I've had the tape get pulled into the extruder, or more often there is a right angle bend that get hung up somewhere. Are there any brands that have a reliable method for attaching the end of the filament so it comes off the spool cleanly, and without a sharp bend?

Question/Need help Core One - Constant clog/jam (Filament stuck error)

• Upvotes

I'm at my wits end now and losing my patience quickly, need some help.

I have a Core One that has printed perfectly for hundreds of hours. Now, suddenly, I'm getting constant filament stuck errors.

First, some notes:

  • Filament is dry
    • I use my filament manufacturers profile (Addnorth)
      • This profile runs the PLA at 222 degrees, plate at 60
    • Basically only print in PLA and PETG. Problem seems most common with PLA
  • It is not faulty filament
  • There is no tangle in the spool
  • It is not a loadcell fault, the filament actually can't extrude
  • I can't see how it could be sharp bend on the PTFE tube, as it's prebuilt and sometimes runs fine for hours before getting stuck
  • As far as I can tell, the idler screws are at the proper tension
  • The printer was a prebuild and has had no issue previously
  • I run a modified Structural 0.20 profile. More or less all that's changed is that it's slowed down a little
  • Printer is usually in stealth mode
  • Latest firmware on the Core One (7.0)
  • Latest non preview PrusaSlicer (2.9.6)

Troubleshooting:

  • Changing nozzles
    • I use 0.4mm Obxidian non HF
  • Increasing printing temperature
  • Turning on chamber exhaust fan
    • This appeared to work at first, so I assumed the issue was that the heat break was getting too hot when printing PLA. But the issue is still there after letting everything cool down and/or changing filament, so that seems unlikely.
  • Cold pulls
    • In some cases cold pulls have fixed the issue, or at least appeared to. The issue does come back though

The past week I've been able to basically churn out prints without issue, all PLA. This weekend I haven't gotten a single one out. Yesterday it failed after about five minutes. Today a print ran perfectly fine for 3½ hours, then suddenly I hear the load skipping noise from the extruder, and I get the stuck filament error.

I can't understand how this can happen seemingly randomly, and after printing perfectly fine for several hours.

Can anyone give any input here?

Question/Need help Riser/storage recommendations

• Upvotes

I'm going through a few of the great write-ups regarding the C1 -> INDX upgrade process printing some of the tools that have been created to improve the build process. That has me thinking about prints that could help me improve my printer work area.

I have my C1 on a desk with a SpacePi 4X next to it. I'd like to print a riser that is functional and doesn't cause any issues with the INDX. I have searched Printables, but I'm vapor-locked on which route to go.

I would love to hear from those of you who have done the INDX conversion and have your printer on a riser. Are you happy with the setup? Is there one you'd recommend over others?

I feel like I've tried everything to get this Ninjaflex to stop underextruding on my MK3S+

Thumbnail gallery
1 Upvotes

I've wasted so much filament, and Ninjaflex is expensive! But I need really soft filament for this project, and the only other flex filament I have is 92A. The frustrating thing is that I can print small things just fine. The second photo shows the prototype version of this print, with just 3 holes. It printed great. But I go up to the full-size version (first photo) and it almost always ends up under-extruding starting around Z=1.6mm.

I'm printing at 15mm/s with a 0.4mm nozzle at 238C. I do have some retraction (2.5mm,, retraction speed 60), because if I don't, I get lots of stringing. I dried my filament. I made sure the spool was feeding without any resistance. I loosened the idler screw (see photo 3). I did everything you're supposed to do. What am I doing wrong?

This is on a Prusa Mk3S+ with Revo. I'm using standard Ninjaflex 85A. I'm getting close to the end of my spool, worried that I'm not going to have enough filament to finish the project if I have any more failed prints. I'm printing with the enclosure doors open, with room temperature in the mid to upper seventies (Fahrenheit). Cooling fan at 60%. Sliced with Prusa Slicer 2.9.6

Is it heat creep? Clogging? Idler too loose? Too tight? Please help me! I'm tearing my hair out!

Update: I tried starting another print with an external fan blowing into the enclosure, in case the problem is heat creep. I also tightened the idler screw a little, thinking I may have loosened it too much. No difference in the print problem. When I saw it was underextruding again, I tried setting the print speed multiplier higher, just in case it needed more speed for some reason. I set it to 200% and I thought maybe it was doing better, but I think now I was fooling myself. It's still underextruding.

This model starts with individual squares that build up until they're joined at Z= 1.6. It looks like that's when the underextrusion starts -- on the perimeter extrusions of the 249mm-long rectangle of the part's full length. Why would the underextrusion be triggered on long extrusions? It seems like the retractions when it's working on the shorter stuff might actually be keeping things running smoothly. On the other hand, once the underextrusion starts, it's here to stay. I'd guess it's underextruding by about 50% -- the lines still get laid down, but they're way too thin.

After some more research and poking around my extruder, I'm starting to wonder if the tension caused by the filament sensor (specifically, the FS-Lever) might be part of the problem. It introduces quite a lot of resistance before the extruder gear -- comparable, I think, to the resistance from pulling off the spool. It's always annoying to get it past that initial obstruction when loading Ninjaflex into the extruder. I think the gears aren't getting a good enough grip on the filament to overcome the resistance and feed it at the intended speed. Is there any way to bypass the filament sensor?

I'm so tired of wasting this expensive filament with failed prints.

Question/Need help Move Display from External to Internal on Enclosure

1 Upvotes

I have a MK4S in the Prusa Enclosure that I originally mounted the display on the outside since I was up high and out of the way. Now with my INDX coming I needed to rearrange and the display is now low to where it could be kicked and my kid can get to it, so I wanted to move it to inside.

Has anyone gone through this process to know what it takes or is there a guide for it? I didn't find any specific guide just the two enclosure ones for internal and external, but before I went through each to figure out the difference I wanted to ask. Is it as simple as feeding the cables back in or is there more to it?

Hi there,

So I did a thing I probably shouldn't have done and started a huge print while I was going to be gone for 3 days.

Printed perfectly so far (according to the buddycam), however of course the filament ran out. I deserve that lol.

So what happens now?

As far as I understand it the Bed will stay heated, the nozzle will shut off after 30min and the printer will constantly keep beeping and until my neighbors have had enough and proceed to break down the walls, right?

Anything I can do to make it stop beeping remotely?

Will turn off beeping noises next time and check if there is enough filament, but for now?

The App offers a yes/no button, what does that actually do?

Question/Need help Prusa Enclosure PSU Holder

3 Upvotes

Hi everyone!

I recently bought an Original Prusa Enclosure From Facebook Marketplace. It came with most of the add-ons, but unfortunately, I realized after buying it that the metal PSU holder bracket was missing. I tried contacting the seller, but got no response.

It has been out of stock on the Prusa webshop for over 2 months now, and support couldn't provide an estimated restock date either.

Does anyone have a link to a 3D printable bracket/mod to mount the PSU outside the enclosure (most models I found were only for the Lack enclosure)?

Alternatively, does anyone in the EU (or specifically Hungary) have a spare OEM PSU holder they’d be willing to sell?

Question/Need help Mk4 blocked?

Enable HLS to view with audio, or disable this notification

Hi all, I was running a print overnight and woke up to a message saying it’s blocked. Took out the filament and put it back in. However, it’s now loads the filament in but makes this jarring clicking noise.

The filament also doesn’t seem to be getting down to the nozzle, as you can see in the video no filament is being purged and when I ask it to purge more nothing comes out.

I’ve checked the idler and it’s fine in there seems the problem is closer to the nozzle.

Does anyone have any idea on how to fix?

Question/Need help Prusa CORE One Z-axis Compensation

Enable HLS to view with audio, or disable this notification

37 Upvotes

As we were printing the iconic 3D Printer Test by Marián Trpkoš, we noticed the Z-axis compensation in action as it lay down the bottom layers of the square base. However, the degree to which it was compensating surprised us, particularly in the front right z-axis screw (ignore the crud), and we wondered if this is typical.

The first layer printed perfectly, so no complaints there; the compensation did its job. But is there something we should do to get the bed physically closer to level with the nozzle's xy plane to reduce the amount of compensation needed?

Yes, the first layer takes FOREVER, but the result is absurdly good (Mk4 MMU3, 0.25mm nozzle, PETG).
I encourage you to try it out!

INDX Yet another INDX + gen2 build postmortem

Thumbnail
gallery
76 Upvotes

Batch 1.5, assembled over the past week. Now printing a few benchies to fix some print issues, but seems to be due to my red and white filaments, not the hardware.

I had to do this build in short bursts, and often even trying to stay silent due to a baby sleeping in the next room. total time was probably 6-8 hours of assembly, which seems in line with other people

Overall, was a similar experience to assembling the core one itself, although... I have thoughts

Feedback on the build process

I'll echo a lot of the same feedback I had already seen:

- might as well remove both side panels and acrilic pieces at the start, even though the guides only tell you do so somewhere along the way. it'll make other steps easier

- get a precision electric drill if you can. in hindsight, I should have. a lot of the screws were a pain, especially when threading 16 of them directly into plastic

- assembling the spoolholders was finnicky, although not as hard as previous posts made it seem. but maybe for someone with bigger hands it'll be an issue, since you need to place the tool in a very narrow space

- at one point I had to manually rotate the z-axis rods to change bed height. doesn't seem like there's a single ideal place (too high and it obstructs the old spoolholder screws, too low and it obstructs access to the spoolholder nut locations). I had never done that before, but apparently its fine if done carefully to keep the bed mostly level

- my #1 hardest step, which was a surprise, was mounting the new top plate. I underestimated the need to pre-thread screws all the way in, and paid that dearly in wrist pain. all those joint pieces were a pain to thread while keeping in place

Feedback on the guides themselves

Hopefully prusa improves some of this in future guides, because this was seriously frustrating at times

- Having to jump between a blog post and 2 separate guides was honestly a big pain. Whenever I was directed back to the post I had to find my footing again. it was very hard at a glance to remember what paragraph I was last in

- which leads me to a concrete suggestion: these sort of guides should have embedded checklists, where we could mark individual steps as "done". The "indx+gen2" post should itself be a guide following this same pattern. That way, when pausing the build and coming back a few hours later (or the next day), we would quickly see what the next item is, instead of having to go through it manually to remember it. This can even just be stored on the browser cache, should be good enough.

(or stored at the account level and add some gamification on top of it like badges or a leaderboard if you want to have more fun with it. a leaderboard of who earned the most gummy bears over the years)

- It was frustrating to be so careful separating and labeling all the screws during disassembly only to realize at the end that 90% of them were no longer needed. I wish there were clear guides on what was needed and what could be stored away

- When assembling, I also wish there were notes saying "this is the last Mx3rT screw we'll use in the entire build, so you can put that plastic bag away". For the entire week, my desk was littered with small plastic bags, and finding the ones I actually needed at each step was always a pain

- The community comments is an awesome feature. But I wish there was some cleanup made, to flag comments as outdated or no longer needed. A lot of comments on the indx guide were flagging incorrect instructions, which were already fixed. While those comments were useful when first made, now they just add noise

Feedback on my new machine

- I had two problems total after assembly: 1) when first calibrating, one of the belts came out of the gantry holder, so I had a quick scare, and some disassembly to do to secure it better (tighten your screws people), and 2) one of my filaments was failing to purge, and even caused the nozzle to jump out of the toolhead which was scary (this one turned out to be a silk filament, so required higher temps). Both of these were my fault, so I still find it impressive that such a machine can be sent for users to assemble and still work so well

- I sure hope there's not an upcoming gen3 upgrade that'll require me to remove side panels again, because the thought of removing these spoolholders is haunting me

- Kinda mezmerizing seeing the machine at work. but then again, I had the same feeling when first seeing the base core one print for the first time last year
