BIGTREETECH Octopus V1.1 32bit Control Board + TFT35 E3 V3.0.1 Touch Screen Display + 8xTMC2209 V1.3 Stepper Motor Driver DIY for Voron V2.4 3D Printer Controller Board Support Klipper Raspberry Pi

Great closed-loop motor. It works perfectly with my BigTreeTech SKG V1.4 Turbo board. The screen is big and bright and the menu is easy to learn and operate. The cable makes connection to the controller board easy and eliminates the need to buy a controller chip like a 2209. Recommended.

Works well and simple to setup. The buttons for the menus can be temperamental at times. So slightly sub par design choice where they are concerned. But beyond that can’t complain.

I was making a robot that used a stepper, and this works beautifully for very fast and accurate control with an Arduino or something similar.Picture shown displays the pinout of an A4988 module, which the breakout included is meant to be a drop-in replacement for. This confused me a little bit, but all you have to do is hook up your motor's voltage source (like 24 volts in my case) to the pin labeled VM on the corner of the breakout. Connect the ground to GND, and make sure the same GND is also connected to the Arduino. Then, as shown in the image, there are pins on the other side named EN, STEP, and DIR. You want to connect EN to ground as well to enable everything, and use the STEP and DIR signals from your Arduino just like you were controlling any regular stepper motor with a driver. DIR signals what direction to be going, and STEP signals when steps should be taken.Make sure to look through the menu on the screen (it will turn on with just motor's power source on VM and GND), and change the step count, or direction, and make sure to calibrate it, etc.I hope this helps others looking to use this module for non-3D-printer tasks

I had a power problem with 3D printer. Instead of 24V it delivered only 1.8V probably due to an overload. The main printer board just shut down, but one of S42C started to emit smoke. Had to buy another one (and upgrade the PSU)

This board came packaged well, but was missing the TCM2209 Driver chips that were listed to be included with the order. All I received was the main board and screen. I will be needing to either return it and play the lottery again, or just fork out the extra money for the driver chips on the side. Please correct this either with the listing title, or with the warehouse that is packing and shipping.

Jumped into my Arduino project with the High Speed Closed Loop Driver Control Board and 42 Stepper Motor, and wow, it's been a smooth ride. This motor is quiet and packs a punch with great torque and speed, making my project feel like it's got a secret superpower.The built-in driver is a dream – quiet, smooth, and feels premium, not like some of the cheaper ones I've tinkered with before. It's nice not to have the constant whirring in the background. However, diving into something a bit more custom, like looping motor feedback to my Arduino, turned out to be a bit of a puzzle. The instructions weren't much help for non-3D printer tasks, leaving me to figure it out on my own. It seems doable, though, and I'm not giving up yet.Also, for those who might be wondering, the driver's microstepping starts at 2 steps, missing out on a full step mode. Not a deal-breaker, but worth mentioning.All in, this stepper motor and control board combo is a solid pick. It's been mostly good news for my projects, making them run smoothly and quietly. A little more guidance for us DIYers would make it perfect

Had been searching all over the sellers site for documentation on this controller board kit. Thought, well I'll just buy it, because I'm sure there will be documentation with the product. Nope! No pin-out diagram. Zero documentation, not even a link to documentation. What sad product support! Deciding whether to send it back now or torture myself trying to set it up blind.

First off, I love the design of this board. Very easy to deal with.. The problem is have with it, is that when I purchased this combo... the board arrived with dead pins. Fan ports not responding, even with jumpers placed correctly and pinouts assigned in marlin.
