E3 Mods

Hello everyone,

I am going to try and explain as best I can and I hope someone can help. I recently bought an Ender-3 pro along with a CRTouch auto bed leveling sensor. I installed the firmware for the CRTouch but now my screen is all out of wack. The screen is no longer a nice clear description of things. its almost as if there is TV static all over the screen. I cannot think of the right way to word it but the display no longer reads clear words. PLEASE HELP!!!!

I recently purchased a micro swiss all metal hotend and installed it on my ender 3, but I can't figure out how to update the Cura settings to allow for hotter prints. Can anyone help?

I purchased Gulf Coast Robotics Modular 3-Point Y Carriage. it worked great but i bought another ender 3 pro and when i installed it on this one it hits that Y axis stepper motor bracket. Im wondering if anyone has or knows of a bracket that can help me with this or some other solution.

Hey folks having issues with my parts cooling fans and that they pulsate with a "da da da da da" type sound. Doesn't make it when at full power. They still work but pulse type thing... Upon checking with multimeter when the power it at anything other than full the voltage is jumping give or take 8-10v which I assume is why the fans are doing what they are doing. Replaced fans, same thing, replaced cable, same thing, put original fan back on that came with the machine and yet no joy either. Tried into 2nd port on motherboard, same thing which leads me to think there is an issue with my motherboard?

Ender 3 v2
4.2.2 Board
Was working fine. Disconnected some bits to add dual z setup (not plugged in yet as I wanted to make sure all still working before I added wire) I also followed and triple checked wiring on all ports on the board to make sure all was in correct place.

Hi. I just got a v2 for my E3, and installation went fine, it starts up with the installed Marlin 1.0.1, but that's where i'm stuck. My only means of putting a .bin on an SD is using my phone, then placing that SD card in the v2.

After inserted then printer turned on, it just starts as usual with the already loaded software. At this point, if i pop the SD in and out, it registers inserted or removed, but i get "No TF Card."

If quicker/easier, updating the Firmware via USB is fine, too, i'm just not technical, eager to get back to printing. :) I've tried three different SD cards, no luck.

Thank You for any help.

Hey all,

I recently got a dual extruder for my Ender 3 Pro (IDEX dual extruder) and I'm having trouble printing with the second extruder

The second extruder has a habit of failing mid print. It can’t extrude the filament, and makes a slipping, thumping sound when printing, causing there to be incomplete infill. Here's the strange thing though, when I stop the print to check the filament, it's not clogged. If I extrude some PLA after stopping the print it comes out just fine.

I’ve tried increasing the temperature, changing the nozzle, and slowing down the print, but it continues slipping. I tried doing a test print file with two different color blocks and that file printed successfully, but this other file continues to fail. Both files use the exact same print settings. Something interesting to note is that even in the test block print, I hear occasional slipping, but the print still comes out successfully

I’m thinking it has something to do with either the extruder motor, or the print settings, but I’m not completely sure. I’ve ordered another brand of bowdin tube as well in case that’s the problem. I’ve also attached the file I'm trying to print, the test file I made, and some pictures of what the failed print looks like. You’ll be able to see the weak infill the higher the print goes and stringing in the photos

Please let me know what you guys think, I feel like I'm reaching the end of ideas I've got. Thanks

Had a mainboard fan die on me the other day, so I decided to upgrade to some quieter Noctua fans on the extruder head while I was ordering fans. Replaced the mainboard fan with a 24V BTT fan, and the parts cooler/hot end fans with Noctua 4020 12V fans. I went to install and calibrate the buck converters, and got 24v fine off the hot end fan leads, but I'm getting mixed readings on the PC/MB fans. For whatever reason, upon setting the fan speed to 100%, I'm only getting a max of 10.5V that will peak at that upon turning on that setting, but then usually slowly drops to around 9~V where it'll stabilize. The MB fan is small enough to start with this voltage, but the Noctua fan won't even start spinning until it sees 12V. I upgraded to a V2 screen as well, and when setting the fan speed to 150%, it'll show 12V. I tested the power supply voltage and got 24V, tried swapping the mainboard, kind of at a loss here. Any insight would be appreciated!

Update to this already: it looks like swapping back to the old screen and flashing firmware for that results in it putting out the correct voltage when the fan is set to 100%. Right now it looks like the V2 screen/firmware doesn't call for the same voltage when set to 100% as the stock screen and I'm not sure how to address this particular issue

Hi,

I just ordered the BIGTREETECH SKR Mini E3 V2.0 to replace the Creality 1.1.5 board that I toasted the other day. This SKR version (2.0) seems to be fairly new so I was wondering if anyone has had any experience setting this up with Octoprint and BLTouch.

Thanks.
