Random 3D printing chatter

Well, I've checked everything I can check now. Hotend simply isn't heating.

All the wiring is fine. Checked every connection. Thermistor is working as I can see it change if I change the temperature in the room.

Is Creality support worth using or should I just send it back to the rainforest while it's in the 30-days?

Can't help with that question as I've never dealt with their support but from what I hear it's a struggle.

You could try replacing the heater cartridge, I mean they are some what of a consumable anyway.

Meh, screw it, it's going back to the rainforest, not putting up with it failing within a week. Now the fun of disassembling it all :(

a new heating element is pence. Id consider buying a couple of spares. as above they are super cheap and basically consumables. 5 for 8.99 on the forest ;)

Isn't petg 70-80 on the bed, something to do with glass transition temps for petg which I think is 80 degrees. So you want to keep the bed in that region and not above 80.
I was having issues with adhesion in general, and 85 was the point it started sticking to the bed properly. I have since started using hairspray on the bed, so perhaps I can back it down.

One weird thing, is that it only really happens to thicker area's of print, so happens later into the print. I added some 'disc's to the corners to help keep them down, but it still lifted in that heavy print area. Far as I'm aware the bed is level.

Take away:
1) I'll try lowering bed temp.
2) I have a sample of 'nano' bed liner coming that is meant to be very good.
3) I'm thinking about making an enclosure for the printer, to keep heat in, as cooling too quickly can apparently cause warping with PETG/ABS (especially since it's in the basement).
4) Maybe that area of the bed is colder/hotter. I will try and move the print away from that spot.

I used to have all manner of adhesion issues on my old printer. Since I have this new one with all glass bed and 600w 220v heater its a revelation everything sticks like glue and i print everything petg/pla/tpu with 50 degree bed.
 
I've just received my ender 3 v2 after shipping delays
I've unpacked it ready for building tomorrow and noticed that when I've removed the glass bed, the metal heated bed underneath is scratched in a number of places with a few very small chips in it also.
Would this affect the heat up of the bed and not give a uniform heat or is it just comestic do you think?

Can you post a picture?
 
It's just a slab of metal, little scratches like that aren't going to noticeably affect the heating.

With my OG Ender 3 going back for a refund, considering an upgrade to something quieter. May just bite the bullet and get the CR10S Pro V2 for auto-level goodness. Although the Ender 6 plus a BL touch is similar price.

Need to check what I can fit too...

Bl touch is good i just add g29 at the begining of any print and it does some leveling and away it goes. Really does work wonders, i was sceptical at first but im getting top notch prints now.

Have decided to make a little herb garden out of the rainbow pla... get a few of these going with some herbs in and see what happens :)

Those are top notch mate :)

Not bad aye - The printer is an absolute beast :) It is also pretty much silent in operation these days, all the cooling fans are now Gelid silent 4's and i'm working on a converter for the hot end fan, I will very possible change the Titan over for the Titan Aero but that's a job for another day. Today/Tomorrow I should take delivery of the 7" lcd that im going to also have on it for octoprint etc. Just enjoying the building and modifying tbh. Might work on the perspex enclosure soon as well. No rush on these things just take it as they come!
 
Progress has been made, now final firmware configuration . With RepRap firmware one ! out of place can really cause you some troubles, ask me how I know, haha.

That's coming along great :)
 
Lost notifications and missed pages of posts. Good to see everyone's doing well. @Vince "New" printer looks like it's coming on well!

I went and bought myself an E3D Hemera to address my extuder issues and hopefully drive a 0.2mm nozzle. Yeah, I thought it was largely going to be drop-in with perhaps some bracketry to rustle up. I got about three levels deep in the to do A, you first need to do B. To do B you first need to do C.....and lost the will to live. I've got issues with cooling on the Ender board anyway - specifically how it drives the part cooling fan with some weird ground-switched pseudo PWM that causes a fan to make a hideous noise. Also, I'm not sure why but my steppers were pretty silent before but now play tunes. The board is 8-bit, needs a mod to program and add a boot loader and then ...and then...and then.

So, long story short, I'm thinking of buying a replacement board and getting that up and running with the new extruder. I'm thinking it might as well handle BLTouch out the box, have better fan control and the possibility of a second Z stepper. No point buying one that's already maxed out, right?! There are a few like the Duet that look good but should be for the price! What are people's thoughts on a BTT SKR ? I was thinking the E3 Turbo that seems to be essentially a 1.4 Turbo with the stepper drivers mounted onboard. I'll have to check, but I suspect the mounting holes on that might be the same as my Ender 5 board which would save some work and also some height in the case that I don't really have. Is there a downside to the drivers being onboard? Are there any notable feature differences I'd be missing? I can't see any but I won't have a clue what I'm doing until I've already gone the wrong way....hence asking :D
 
This was a 34 hour print lol! but only because I didn't reset the layer size - it was left at 0.18 from the last job and I forgot to change it to something larger. So it ran for an hour or two before I noticed it seemed to be printing slow :) Still, the finish is great with the MKOEM silk silver filament (I just went with was loaded at the time). Object is a rack for 25 airbrush paints (printed on CR-6)
