Man, still after so many years on 3D printing world, and CHEP still gives me lessons, I was having elephants foot issues, no more thanks again to you Sir! Have an amazing sunny day!

I learn something new in every single video of yours. I knew about ironing from your previous videos but "line width" effecting the surface quality is totally new for me and I'll definitely try it, thanks for the heads up 👍
SuperSlicer offers Ironing, with no tweaking required. And since its a fork of the PrusaSlicer it has excellent elephants foot compensation. what i like the most is the included suite of calibration prints to dial the printer to perfection (as far as the printer lets you). Combine that with Klipper and all of its features and you can go crazy :D
@Tony Lewis if you mean Klipper, it runs on 32 bit arm boards, but it is dependent on a pi, since kinematics are calculated on the pi... The printer board just executes what Klipper on the pi tells it. It's no nonsense IMHO, since running it only on the printer board would defeat the purpose of Klipper (easy firmware changes without reflashing for example) plus I could not live without plugins like Tasmota...
I'll check that out but I have to tell you with the troubles I had with my Ender 3 the direct drive and the Ceality Magneti bed made all the difference. The magnetic bed is awesome. And I used to like glass but they wear out too soon. Thanks for all you do Chuck.
Been picking up 3d printing only a few days ago, and your videos are great. Not too lengthy and full of rambling, but very informative. And this video is perfect, since ironing seems to make it look so much nicer :D
This is fantastic, I'd been frustrated by elephant's foot for a while now, and lo and behold Cura had a setting to save the day! Thanks so much for this video and the working example!
The elephant's foot tip was extremely useful. I was able to almost eliminate it from my PETG prints. Thanks so much for your brilliant content. This is by far the best 3D printing RU-vid channel. I always recommend it for beginners. By watching they will soon become experts. Great down to earth information presented clearly. Systematic and nothing left out.
Chep, I've yet to find one of your videos that doesn't pertain to me. 3D Printing is like piloting a plane with all the settings and adjustments, and your explanations are super easy to find on your channel in a pinch. Thank you for helping me print better.
Thanks man! I've been scratching my head about that elephants foot for a while now. And the Ironing was a setting i never knew i always wanted. Much love!
I always run my line width 10% less than the actual nozzle. .4=.36, .6=.52, .8=.72, etc. Also be careful ironing larger surfaces like the top of a plague. Running the extruder at a 10% feedrate for prolonged periods can lead to a clogged extruder. It just can't handle the heat creep. I did that a couple of times before I figured out what was going on. I really like the idea of reduced line width on the top. That should alleviate the heat creep completely. Another great video, keep 'em coming!
You can do more with Cura: applying the "fake ironing" with a reduced line width ONLY on the "skin" (must be activated in the "Shell" tab) and not on all top/bottom layers, to save time. The width of the skin line is in the "Experimental settings". The skin also have a LOT of specific parameters: they can be completely different from the top/bottom settings...
in 4.7 i didn't have good results and i go back to 4.5! now on 4.7.1 with some my usual changes on stock profiles and add a horizontal expansion at -0.1 i have great results!! thanks Chuck!!!
Hey CHEP, I love using you profiles on my Ender 3 Pro. Thank you for going through all the trouble in researching all this and for making it available to us.
I LOVE your videos! I'm fairly new to 3D printing, & am learning as much from you & your videos as I possibly can, BEFORE I try to print a cab for my Rc semi truck!
I’ll certainly check out the ironing feature. Since switching to your profiles, my prints have been FANTASTIC. Save for the tops. Not terrible, but not like the sides.
Try setting a couple top surface layers, and then setting only the top surface layer width in the experimental settings to less than the nozzle width. Cuts down on the added time of having all the top and bottom layer lines so narrow. Can also set the initial layer line width percentage down for a narrower first layer line width.
SuperSlicer (which is a fork of PrusaSlicer that includes some features from their common ancestor Slic3r that Prusa chose not to include) has both elephant's foot compensation as well as surface ironing.
Your cube for the first layer expansion compensation could in fact still be a little flared out. I've made the observation that the value should be more like half of the measured flare plus 0.03mm (0.05 if you want to be extra sure) in negative, then it's spot on.
SuperSlicer, a PrusaSlicer fork, has Ironing, and works better than Cura. I get super smooth surfaces, with Cura I get always the mess you got. Give it a try. I have much better results with it than with Cura. Has extra features than PrusaSlicer, and frecuent updates.
I find that faster speed (+40mm/s) and less flow (5%) when ironing is better with both PLA and PETG, otherwise I usually see some squished nozzle tracks here and there (not combing). Reducing the inset can also make a big difference on small areas when using the zig-zag pattern. But the increased speed drastically reduces the negative impact (time-wise) of ironing.
I tested ironing with different flow rates. I noticed that for me 0% was the best. Anything higher had uneven deposit of excess material on the top. But these were single layer discs I was testing.
I found a remix of your rear mount spool holder. You can even use the EZRStruder. It uses a 90 degree turn that actually works very well with the EZR. Probably not with the stock extruder. It also moves the spool out farther to the side for clearance
@CHEP You probably should play around with the Line width settings. 0.26 is way to low. Try around 0.35 and have a Look on the flow then too. Got me better surface than any Ironing. Downside, If you change the nozzle you would have to check for the best setting again.
Fantastic, as usual! Would you have a profile for air/water tight prints in Ender 3? I've seen you need to apply over-extrusion and other techniques...
Same for me. It downloads, but when I get to the printer set-up screen it constantly hangs up. Windows 10 says its looking to sort the problem and then closes the Cura 4.7. I had to re-install 4.6
Check superslicer, is a community based slicer and has similar advanced features! The had ironing which is working well for the last 3-6 months! I am nor sure if they had it before I discover the software during lockdown :D
And include elephant foot compensation too and a large amount of customisations making really powerful, for me better than Cura. CHEP could be perfect if you can include this slicer for a tests as the community is growing really quickly.
Dobre rady. Używałem DIMAFIX, klej do przyczepiania, jest chyba najlepszy na rynku oraz obniżałem temperaturę stołu do 40-50 stopni aby nie było stopy słonia. Bardzo mi pomogłeś też z kompensacją wymiaru otworów. Dziękuje i pozdrawiam z Polski.
