I would like to use a inductive/proximity sensor for bed leveling, but can not seem to find one that is "plug n play" with the 5v BTT port on a SKR 2 board. is there such a beast out there, something that does not need to have a 12v lead run to it, and then additional component(s) between the sensor and the MB? looking for suggestions

I want to operate this motherboard using a Meanwell 24 VDC power supply and a 48 VDC poweer supply. As the power supply of the motherboaed is delived by 2 independent power supplies, is it necessary to connect both Dc Grounds to ensure same level for the ground or is the 48 VDC supply isolated from the logic an so independent power supply units can be used?

I just got the CB1 and Haven't been able to get it running. I boot it up and the ACT light just keeps blinking in a regular pattern. I read on the PI forums this means there is a problem with boot up but I don't know what. I tried to latest firmware and the second to last firmware twice. I thought it was low power so I bought a power supply for the PI 4b but that didn't change it.

I just received my SKR Mini E3 v3.0 this week and installed it in my Ender 3 v2 with BLTouch last night. I chose the kit with the modified cable for the stock Ender screen. I started the machine up with the SD card inserted and it didn't appear to take the firmware (no .CUR). I reformatted the card and tried again, and now I have the firmware.CUR file on the card. This tells me that apparently the board is receiving power and able to install firmware. However, I still have a constant red light and a blinking red light right next to it. The fans don't seem to spin up and the display doesn't change. I have tried to start it up with the BLTouch removed, with t…

Hi~ One SERVO PORT is being used by bl touch. But I need one more. Previously, "SKR Pro" used the bl touch sensor port as a servo port. In OCTOPUS V1.1, the servo motor does not work. I'd appreciate it if you could tell me how.

Hi guys I`m new in the 3D printing world, and I recently purchased a controller board, SKR mini E3 v 2.0 to upgrade my printer. As I don't have much experience yet, I would like to ask for your help in a problem that appeared. Is there any way I can use my printer's endstop servo with this card, or would I need to replace it with a bltouch? Thanks in advance for any help ! ^^

I'm under a lot of stress with a recent error. I didn't even change the firmware. This is a gcode file that was working normally. How do I deal with new errors? https://cafe.naver.com/makerfac/174643

Hi, I bought and set the card, it's silent, but I have a one problem. During printing temperature of the nozzle jumps as a mad rabbit. I've checked connections, calibrated PID for this temperature exactly - nothing helped. When temperature is set 210 I can see peaks 199 - 220. What is the possible problem and how can this problem be solved?

I just upgraded my board to a E3 Mini V2.0 and noticed that when using the standard firmware 2.0.8 that my hot end heats up after powering on the printer and the display is reading the temperature just fine. It did not do that with the stock board. Is there a firmware fix for this or did I just get a bad board?

I am upgrading to the SKR mini E3 3.0 board and the TFT 3.5 E3 V3.0 on my Ender 3 Pro. Should I do the board first with the stock screen on, flash the firmware then install the screen and flash that or can I do them both at the same time?

Hi dear community, i'm an bloody noob, first day with my octopus 1.1 and first try to send a command like 'G0 X10 Y10 Z10' to the board from my ubuntu box (Ubuntu 20.04.4 LTS x86_64, Kernel: 5.4.0-124-generic). what i tried: $ lsusb | grep STM Bus 001 Device 018: ID 0483:5740 STMicroelectronics Virtual COM Port fine, i have connection.

Installed the SKR Mini E3 V3.0 to Ender 3 Pro and was previously using a micro SD to SD card extension cable adapter and I now get the "SD init fail" message. I tried using multiple adapters that I use on my other Ender 3 with same message. When I use the basic micro SD card it works properly so it's definitely not my micro SD card slot being damaged. What can cause this error and is there a fix? e

I have an Octopus Pro loaded with BTT TMC2209 (some 1.2, some 2.0), TFT35 v3, dual Z-axis motors and a Phaetus TaiChi mixing hotend. Working with latest GH release (Marlin-bugfix-2.0.9.3.x) and I'm having issues with the parts cooling fans not turning on with the display or by M106. I have verified pins_ has the correct connections defined for FAN0 and FAN1 and I have them set for 24V feeding two 24V 5015 blower fans that have been verified as operational. Also, I am getting "All Low" when the TFT connects. A representative on Facebook messenger was only willing to offer ""All LOW" is the error reported by the TMC driver, check the driver type settings in the …

I am replacing my CR10-S4 motherboard V2.1 with a BTT SKR mini E3 V2.0. All of the wires correspond to the board except for the 2-2 pin wire connectors labeled on the CR10-S4 as VIN or always on fans. Where do they go? The only place that makes sense is the Power location next to the Bed. But that is for only one-2 pin connector. What is the solution to this problem? Thank yyo for your help with this.
