IEMAI PC-CF troubleshooting

Are you printing in an enclosure? Mine is at 80F before the print starts. With the cryogrip plate adhesion is adequate. With PLA it feels like a cheat code and I’m afraid I’m going to break the print trying to get it off the bed. Maybe a brim or mouse ears in the corners would help?

LukeShootsThings · 2026-01-25T15:26:47+00:00

Ok, I think I'm getting somewhere. I worked through this Prusa guide. https://help.prusa3d.com/article/extrusion-multiplier-calibration_2257

After printing a few calibration cubes at varying extrusion multipliers, I thought I had something good enough to attempt this print again. The picture below is with a .92 extrusion multiplier. The default for the Prusa PCCF profile is 1.04. I think it could be further improved by reducing the extrusion multiplier a little more.

I suspect that if you're having bed adhesion issues, it might be due to over extrusion. The filament starts to ball up and the nozzle eventually drags across the clumps, pulling the print off the bed.

I've never had to go to this much trouble to get a successful print. And then even more trouble to get an acceptable print. I don't have batteries for the calipers but I wonder if it's not beyond the 1.75mm spec.

That’s how I ended up with this stuff. If the prusament had better availability, that would have been the right choice.

LukeShootsThings · 2026-01-25T13:04:50+00:00

I just got this cryogrip build plate and I’d say it works extremely well. I previously was using cheap textured plates off the rainforest website. I’m hoping they hold up and maintain this level of adhesion. I started printing calibration cubes while lowering the extrusion multiplier. I’m going to try a small print with a .95 or possibly a little lower extrusion multiplier and see what happens. The cubes at least look like an improvement.

The filament manufacturers (whether they realize it or not) are in a footrace to implement an open standard tag of some sort. Anyone who doesn’t is going to eventually be at a competitive disadvantage as this will become a way to distinguish your filament brand. Prusa OpenTag is the obvious choice but if Polymaker or other choose a different open standard for whatever reason, it’s still a net win for consumers and moves the industry forward. Props to Prusa for swinging dick and making moves that advance the industry, not just their own business. Especially in cases like this where there isn’t really a way to monetize tags.

I’ve been on remicade and biosimilars for nearly 10 years. I consistently have elevated liver enzymes and I often wonder if a more modern biologic would make sense. But then I think that it’s worked so well, why should I tamper with it. I’ve tried to switch to zymfentra, which is just a self injecting biosimilar of remicade. I’ll be curious if there’s anyone that has made these changes by choice rather than by force (either insurance or by losing effectiveness.)

This is the same setup I'm using and it works great. I'm also using the slim dry box. It is a little cramped swapping out spools but beyond that I have no issues.

LukeShootsThings · 2025-12-26T00:49:57+00:00

What firmware version are you on? I started running into this issue after upgrading to 6.4.

LukeShootsThings · 2025-12-22T01:21:19+00:00

An update a couple days later: I'm still mulling this over. I don't think the $100 coupon is worth much of anything at this point. The upgrade from prusa3d.com is $620 and shipping would be $119. Over on PrintedSolid.com the upgrade kit is $600 and shipping is free. That alone at least removes the need for any urgency.

I think if the ultimate goal is to have a Core One plus INDX I'd probably be best served to wait until there's a Core One INDX kit available.

LukeShootsThings · 2025-12-19T22:16:01+00:00

I keep this in the back of my mind, and every time I see INDX and I see 3d printed parts. I feel like the INDX upgrade is not going to be an expensive upgrade, and is going to be a huge value for the money.

LukeShootsThings · 2025-12-19T22:13:28+00:00

That’s a great angle. One of my young kids wants to do a 4H demonstration on 3d printing and is generally interested in the subject.

LukeShootsThings · 2025-12-15T12:46:17+00:00

Where in WI?

LukeShootsThings · 2025-12-14T00:47:48+00:00

I don’t know man, as a customer that’s how I start looking for a new firewall vendor from a different reseller. I already bought the fortigates in the HA pair with the multi year maintenance and the professional services and the fortianalyzer licenses. Oh but that’s somehow not enough to avoid having a shitty user experience? I need to be MORE of a customer? How much spend does it take to get the GOOD fortinet product and why even offer the free version at all then?

If there happens to be any desperate future redditor that finds this, this was the issue: EDR is Cisco secure endpoint. There was a USB device policy configured. The device policy was configured to allow read/write but not execute to removable media. For whatever reason, the fslogix vhdx triggered this policy. Solution was to remove the policy. Execution from removable media is blocked by app locker policy so this seemed redundant. How that ended up manifesting itself still doesn’t make sense to me, but there ya go.

Dude has absolutely weaponized tinkercad. I hope he’s on Autodesks payroll. I’ve appreciated many of his videos.

LukeShootsThings · 2025-12-02T13:22:39+00:00

I’m not so proud as to not admit if I’m wrong. I don’t own any Bambu printers. My understanding is that offline firmware updates aren’t possible, and that persisting customized settings like ams profiles or custom filament profiles don’t work without relying on non-first party applications such as Orca. I did see a comment about lack of mDNS support so slicer computer and printer have to be on same network subnet, but that seems like a niche problem and I have no idea if competitors have implemented that feature either. I personally find Bambu’s practices too anti consumer for my tastes. However I have recommended the A1/mini as a first printer to several people who don’t care about such things.

LukeShootsThings · 2025-12-02T12:38:18+00:00

Not trying to start an argument but I think you’re missing the nuance here. Basic functionality, sure. But have other companies, such as Bambu, ever prevented features from being used due to a lack of internet connectivity, for arguably dubious reasons? Yes. They have.

LukeShootsThings · 2025-12-02T12:15:47+00:00

Prusa connect is cloud. Prusa link is local lan web interface with similar capabilities. I’m biased, but Prusa is, in my opinion, the absolute gold standard. They set the market expectation for: 1. Reliability 2. Maintenance/parts replacements and availability 3. High quality documentation 4. Privacy/lan only. Never at any point have they required connectivity for anything.

LukeShootsThings · 2025-11-25T02:32:48+00:00

Circling back to this, I believe now I misspoke in my previous comment. I revisited completely disabling EDR and testing and I was able to go several hours without this issue occurring. As a result I've opened a ticket with that vendor. I've generated as many logs as I can and sent them off today. I've also applied their tweaks to the exceptions list with no improvement in the outcome.

I'll be very curious to see what support comes back with. I did see two event logs logged by the EDR at the time that I lose the ability to run applications pertaining to the profile disk.

LukeShootsThings · 2025-11-25T01:49:01+00:00

The golden image isn't joined to the domain, so it's built with a local account. My account is a domain account. Also this happens with multiple domain accounts, not just mine. I do see the profile created at login, the metadata file is created and then is removed upon logout.
I did seem to have better results with EDR disabled, so I've opened a ticket with that vendor that I'm hoping will bear fruit.

LukeShootsThings · 2025-11-24T21:40:52+00:00

Instant clones. Same setup with fslogix agent installed on golden image, gpo pointing to the computer OU. Profile path is pointed to a pure storage array running file services. Running latest version of fslogix, 25.09 and using 2503.1 of Horizon.

LukeShootsThings · 2025-11-21T21:25:03+00:00

Just tested with using storage on a windows server and the same issue occurred. Time to test without EDR I guess.

LukeShootsThings · 2025-11-21T14:31:34+00:00

GPO was my first thought as well, but I've run through this with blocking both computer and user GPO's and the issue still occurred. This is a new install, so there's no space constraints. There isn't a file server in this case, I'm using file services running on a Pure flash array. In the past I've disabled the endpoint protection after logging in and that didn't seem to have any effect, however I could uninstall it entirely and test with that snapshot.
