Toot

Written by Simonoid on 2025-01-19 at 06:19

Fellow nerds I have a new obsession and it is driving me insane!

I got a second hand Creality cr-10s pro.

It came with some clogged pla. I got this.

I cleared the clogged nozzle with the help of YouTube university.

Next was levelling the bed.

I manually adjusted the gantry and then each z axis both manually and via the touch screen. Using a piece of paper for clearance.

Test print time! It fails to adhere to bed and gums to the nozzle 😔

I couldn't let it go and tried again a few...more than a few times.

If anyone has some time for some one on one via video call or if you are near Western Melbourne.

I will do my best to show my appreciation with coffee/beer/renumeration ❤️

@simonoid Before considering a call ... checklists

1. Raise the nozzle high above the bed, heat and extrude filament. Ensure the extrusion is smooth and consistent. Look for bubbles, steam which could indicate wet filament.

2. Is that the Creality glass bed? If so, scrub with 0000 steel wool and dishwashing liquid. Then douse in isopropyl and wipe dry with paper towels.

3. If that's a PEI or similar bed, scrub with dishwashing liquid and a scrub brush (nail brush works) and then isopropyl wipedown.

4. I'm pretty sure the CR-10S Pro has automatic levelling, so make sure you run that procedure after manually trimming up.

5. Handy Tip: Keep some nylon filament around, preferably slightly damp and run it through the nozzle after a clog and it'll "steam clean" things. This is only valid for an all-metal hotend that can handle nylon temps though.

6. Make sure your belts are tight!

Second hand 3D printers are a potential nightmare because there's usually a reason why people are moving them on.

@PCOWandre @simonoid The CR10S Pro doesn’t have an all metal hotend. It also doesn’t have either a glass or PEI bed, it has a grippy layer applied onto the bed directly.

@teotwaki @simonoid Oh, the Creality knock-off Build-Tak? That's not a great surface.

This locally made product can save one's sanity with poor build surfaces:

@PCOWandre @simonoid I posted my experience with the printer in a parallel thread. Could you double check my review? I don’t want to be overly biased/negative.

@teotwaki @simonoid Sure, pop a link to the thread.

I'll admit I'm at least somewhat biased against Creality and I'm in the Bambu ecosystem wherein printers print and I get to spend my time in CAD designing rather than babysitting printers.

@PCOWandre @simonoid likewise, but with Prusa

@teotwaki @simonoid Based on your list of recommended upgrades, I think the summary could be "buy new printer". Unless one needs the bed size, the cost of those upgrades would find an A1 Mini.

@simonoid Hey! So I’ve had this printer for many years, however it took me nearly a year to get consistent results with it. The things I changed:

• mirror from IKEA instead of the very bad bed

• BLtouch probe instead of the very inconsistent ABL probe that came with the printer.

The ABL probe sadly will be all over the place every time you run ABL. Sometimes it will crater the nozzle into the bed surface, sometimes it will hover awkwardly 1.5mm above the bed.

@simonoid Sadly this printer has been gathering dust in my study for a very long time. It’s not a good printer, it’s slow and unreliable.

If I didn’t have a choice and I had to use it, here’s what I would do:

• Change the ABL probe

• Try to change the bed to some sort of magnetic PEI, somehow

• Remove the bed springs and make it fixed (you don’t need springs if you have ABL, it just introduces wobble/flex/print artefacts)

• Install klipper

• change the fans to make it less of a screamer

@simonoid I think that could make it relatively solid. However, you could go further:

• change to an all-metal hotend. The Teflon tube inside the hotend will deteriorate. We’re also now very aware of the bad things that happen when you heat up Teflon continuously. It’s not good for your health.

• change to direct drive extruder. Bowden setups are great if you’re building a delta, but they really have no reason to exist on a massive i3 like this.

• switch to a .6mm nozzle

@teotwaki all great suggestions!

There is a magnetic flex bed for about 35aud.

And whilst I am not super sure about removing the springs, I've seen you can get some stiffer ones for cheap.

I am curious to try something like octoprint for monitoring and wireless control.

I'm considering I got this for free, and this is likely a stepping stone for the hobbies and more projects along the line 🥰

@simonoid Maybe you could also get fixed standoffs instead of stiffer springs? Just copper or brass hardware store pipe should do. You could get slightly longer and then sand them to get an almost perfectly level bed, and then let the ABL handle the imperfections of the bed surface...

Remember that if you change the bed surface, you'll most likely need a different ABL probe. That's why I recommend the BLTouch (or potentially a clone if going for cheap). Works on all surfaces.

@simonoid @teotwaki Octoprint is almost a must-have for printers that don't have their own network connectivity.

@PCOWandre @simonoid This being said, if you’re going to go with octoprint, you might almost just go ahead and go with Klipper. At least you get the benefit of massively greater speed.

@simonoid So I have an old Flashforge Creator Pro and haven’t done a ton of printing for a few years, but it sounds like you’ve been taking all the right steps… next thing I would check is the filament. Try a different one if you have any; filament that has absorbed some moisture can be more prone to clogging.

As for adherence, I use Elmers glue stick on a heated glass build plate so I’m probably not the best person to give advice for that. 😅
