We have purchased an Octopus Pro STM32F446ZET6 to be used in a laser we are developing, and hope to get it talking to lightburn with Marlin. Unfortunately we can't quite figure out how to connect our laser module (PLH3D-15W from Optlasers) yet. I have read that you can use a fan PWM output and redefine the pins in the firmware build. Is this the case? If so, how exactly would this be done. As much information as possible would be greatly appreciated on this matter as there isn't really anything available online or on the forums that I can find. Thanks, Kane

Hello everyone, I bought your tft screen Bigtreetech TFT 2.4 V1.1 display for a project i'm making. Now for that project I had to flash the tft screen to the latest firmware version of you on github. Did everything as described and this went without any problems. However, after flashing and restarting, I found out that I had not taken the latest version Vx.x.27 but the previous version Vx.x.26 , stupid me. So with good intentions downloaded the latest firmware and put it on sd card and let it flash again. However now the screen keeps hanging when he has to read the config.ini file and then doesn't go any further with the result that it starts up with …

Hi, I want to flash my Octopus Pro V1.0 board using vscode/platformio directly via the USB-C connector. Do want to use the sd-card flash since this is annoying if you need to make to many changes. My Windows10 system does recognoice the Octopus Pro when connected via USB-cable and shows up as USB device on COM3 If I try to flash (e.g. Marlin) on the board, vscode does not recognoce the board and ends with an connection error (board does not answer...) Is there somthing I need to do in order to be able to flash SW directly to the board using the USB-C connector? Or is this not at all supported by this board? Hope someone can help me …

I have printed two thing just fine but when I go to print a third item the extruder motor moves but the extruder doesn’t move. The filament states to extract but it causes an air print. How do I go about fixing this? Just bought it yesterday.

It has only been two months since I got my Biqu B1 and recently I have not been able to finish any print. In the beginning everything seems normal. But suddenly the printer decides to drastically increase the extrusion motor steps. I pause the print, go to settings, and extrusion motor steps are still 96. I change them to 95, save, unload, and still the extrusion motor goes double what I asked the printer to unload. Instead of unloading 5mm of filament, the printer unloads much more. The first time this happened I turned off the printer, started from the beginning and the print finished OK. But now I have tried three times to finish one print and this problem hap…

Hi! I recently purchased a Hermit Crab & an H2 extruder for my Ender 3 v2. I'm having a problem determining how to connect the Hermit Crab to my 4.2.7 motherboard. The provided wiring harness has a several unlabeled connectors and at least two (FLD & EO) which I haven't been able to determine what those acronyms refer to. Also, the concerning is that the manual has a picture of the PCB board interfaces connector wiring which doesn't match mine. The PCB-F illustration indicates that the BL TOUCH connector connects with the orange wire on the outside - mine connects with the orange wire at the other end. (Possibly it's just a mistake in the picture?) Picture …

Entweder habe ich dies in den manuals überlesen oder es steht nirgends. Ich würde meine 12v Lüfter darüber betreiben wollen. Ist dies möglich? Danke für eure Antwort Rico78

Hi all! I install a skr mini e3 v3 in my Creality CR-10s replacing the old creality board. I have in my printer a 3d touch sensor (bltouch clone).

Hi all, I just got a Mini E3 V3 and setting it up for the x and y steppers. I'm trying to get the endstops to register with Klipper. No matter how I set the pins in the config they always say triggered. I've tried with ^PC0 and 1 for pullups and not. The only way they change is with the ^!PC0 but still won't change with the switch. The sensorless jumpers are not installed on the pins. Is there something with the mini I'm not seeing? I'm using the query_endstops command. The board is connected and comunicating with the ras pi4.
