Z-axis moving whenever homing X and Y axis

by ImNotSean

I recently upgraded my Ender 3 V2 to a Creality 4.2.7 silent board (best thing ever!!), but since there wasn't anything wrong with the 4.2.2 board I had before, I decided to use it in a different project together with some nema stepper motors I had lying around. I notice now that whenever I home the X or Y axis (with G28) the Z axis always gets moved first. This was never a problem when the board was used for my 3D printer, but in this other application, I need to be able to home the Z-axis first and then have it stay in place while homing the other two axis. Does anyone know if there is a way to suppress this Z-axis movement?? I would prefer to not have to change, recompile and reflash the firmware if there is an easier way to do this.
Thanks in advance

I MESSED UP MY DISPLAY

by sweatypajamas53

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!!!!

Part cooling fan voltage issues

by jrabkid

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.

Cannot update Firmware to new v2 board.

by e47b

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.

Dual Extruder Troubleshooting (Slipping, Thumping)

by dmgraciano

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
