In your schematic, there´s a jumper (J22) for logic VCC.
This is the same VCC for the stepper logic and the shift registers. If I´m right, this leads to a problem:
The datasheet of the 74AHCT595 say…

Currently, we have `Dir::Forward` and `Dir::Backward` and define them in terms of "this is the direction the motor moves in if DIR is set HIGH/LOW. I'm wondering if there's an established de-facto sta…

Seeing as this seems to be the only repository of knowledge about this board I thought I'd provide the pinout I've probed from my board. Labelled as Developower V2.0. Has a transistor output rather th…

Hi,
I am trying to use a PT1000 with the MAX31865 module plugged into Motor7 slot on the Octopus Pro 1.0.1. The printer reports a MINTEMP error for the temperature when I have the LCD controller EX…

About me, a buddy gave me a CTC 13A (Ender 3 clone) for free. That's how I got to the 3D print stuff and I'm an absolute beginner but I know a bit about electronic circuits.
I bought the board on E…

We would like to see stepper motor drivers outputs.
So you would have an arduino input that gets triggered, and then the motor drives xx millimeter of filament towards the extruder.
At this moment w…

Before I've installed bltouch everything worked perfectly after I've installed it the head moved 10mm up before resuming and print in the air.
I think safe_z_home is the problem not sure I've used in…
