Feeler Guages

by Dingham

On the advice of a member I bought some feeler gauges and I had a few questions.

First: They're covered with gease/oil, I get why. But I don't really want this on my bed. Do i clean them?

Second: So I dismantle? So I can slide them easily between the nozzle and the bed? Otherwise i'll have to bend them, is this ok?

Third: What gauge to you recommend? I plan on testing, of course. But I was wondering what gauge people normally go for?

Printing on sugar :)

by AlmostFixedIt

Well I am printing on sugar for the first time and it is looking great. No problems sticking to the bed and I am well into a 5 hour print. I removed the "brim" in the Cura setting and re-sliced the project and saved it but it appears to have a brim anyway. I guess the guy that wrote the STL file may have used a brim and it was in the code. Anyhow, I will let you know when it's done and how easy it comes off the glass mirror.

2nd Generation Hero Me hot-end cooling system

by mediaman

Check out my 2nd generation Hero Me hot-end mount for all Creality CR series, Ender series (and clones), with OEM, single & dual 5015 part cooling fans, and ABL options(EZABL & BLTouch). Lots of updates from great feedback received from many users: https://www.thingiverse.com/thing:3182917

This update has refinements across most all of the parts. Parts with 'Gen2' in the filename are this second generation. Parts without 'Gen2' have not changed, but are fully compatible with the this second generation.

Improvements include:
Hero Me Base -
Larger reinforced wire guide with much more space for hot-end wires.
Supports OEM and MicroSwiss hot-ends
Easy access channel for top X-gantry bolt

Hero Me Ducts (OEM fan, single & dual 5015 fans)
Greatly improved clearance from lower X-gantry wheel nut
Reinforced and tapered mounting tabs for better fit to base
Refined duct tips for better air flow to parts
Increased adjustable height range for better alignment to hot-end nozzle
Wider channels for the 5015 fan clips (holds the two sides of the fan case together).
Retired 'B' versions of ducts (redundant and wastes filament)

Base Lock, EZABL, & BLTouch mounts
Resized M3 bolt mount rings to better fit the Hero Me Base

BLTouch adjustable wing mount (dual 5015 fans)
Moved mount 2.5mm to the left to give better wire clearance with second 5015 fan
Offset locations updated above
Retired the fixed position BLTouch mounts

EZABL mounts (OEM fan, single & dual 5015 fans)
Refined clip to better fit around base
Added spacers for EZABL mini

Added an LED strip mount.

All updates from Oct-Nov are incorporated in Gen 2 versions.

Extra Fan Pin on Melzi Board

by dogbox257

Does anybody know what pin the extra fan connector under the "Part Cooling Fan" connector is? I tried changing the #define E0_AUTO_FAN_PIN option to the pins that were set as outputs in the Marlin pin file but none other than the beeper worked. I also lowered the threshold temp so that it would be on but I got nothing. I'm trying to get the hotend fan to only turn on once it hits certain temps so it's not making noise all the time (I'm changing the fans so might as well while I'm at it).

Upgrading the firmware on CR10 with the new board?

by ah9illator

I bought a CR10 but when I went to upgrade the firmware, I noticed it had the new, green board. Not thinking it would matter, I followed this guide: (https://www.instructables.com/id/Flashing-a-Bootloader-to-the-CR-10/) all the way to step 4 and got an error saying I had the wrong board. When I turn it on, the LCD is just blank. I don't know how to proceed from here and I worry that I may have bricked my printer, is there anything I can do? Am I even doing it right?

EDIT: I'm a big idiot. The printer wasn't on so it of course refused to connect, hence the issues. I turned it on and flashed new firmware no problem whatsoever. Then I kicked myself for wasting 5 hours dealing with an issue that could've been fixed had I turned the thing on in the beginning.

heatbreak fan issue?

by SirrisRx

I've recently noticed a problem with one of my printers. It can't seem to get the hotend to the temperature I've set it at. So I end up having to manually set it about 10C higher than the displayed temperature; 210C to get 200C.

While exploring the issue I noticed that the temperature can be reached and steady but only with the heatbreak fan disabled. Obviously, that doesn't sit well with me.

The printer is a CR-10 and the it's fully stock without a fang installed.

I should mention that a second CR-10 sitting next to it is printing just fine (I had worried that it might be the ambient temperature being cooler).

Any ideas or directions I might investigate will be much appreciated. Even keywords, hehe. Thanks.

Bed Options CR10S

by AlmostFixedIt

I watched this video https://www.youtube.com/watch?v=BzY2LzDjquU after trying to remove my print today. It was stuck pretty good and I was hoping I didn't throw my bed out of alignment getting it off. I know to check it before each print though anyhow. But then the glue stick mess I had to scrape off with a razor blade. There must be a better way. So has anyone used one of these fairly inexpensive sheets?

My current mirror I sanded and scratched it up with emory cloth per some video I saw a while back. I wonder if a slick smooth mirror surface would be better? I have a box of mirrors. Thoughts?

What do you call your printer?

by Dingham

So my first post was a cry for help and I really appreciate the advice and support that has come through from the community so far. I thought however I do a bit of a more light hearted second post to better introduce myself and maybe help anyone else new to the community.

What do you call your printer? I'm sure many of us are using the OctoPi, if not do, and you have to name your printer... what did you call your print, did you go for just CR-10 or did you choose something more creative.

What did you call your printer and is there a reason?

I called my printer: The Coyote after the Native American 'god' as he's involved in the creation mythology and is known to be a bit of a trouble maker. It made sense to me at the time.
