Dear respected sir, Hope you are in good health with success and happiness. I'm really happy for your awesome tutorials. But I'm facing a problem. I'm making a large size 3D printer where I'm using Nema 23 stepper motor which need 3A current. That's means, I will use 4 Nema 23 Stepper motor. In X axis 1 Nema 23 Y axis 1 Nema 23 Z axis 2 Nema 23 Those A4988 Stepper motor driver can provide maximum 2A current. Therefore, I am using TB6600 high power stepper driver. But I do not know the Pin-out to connect RUMPA board with TB6600 stepper driver. Please sir, could you help me? I will be grateful to you. https://reprap.org/forum/read.php?245,812355,812355#msg-812355 Fri, 17 Apr 2026 12:23:37 -0400 Phorum 5.2.23 https://reprap.org/forum/read.php?245,812355,813001#msg-813001 https://reprap.org/forum/read.php?245,812355,813001#msg-813001 I used the HY-DIV268N-5A and there are two tutorials how to improve them in terms of torque and stepping quality.
following links are in this topic:
Changing ICs => Stepping Quality
Changing resistors and bridging two pins => More Torque]]> Terri Allgemeines Mon, 05 Mar 2018 08:39:09 -0500 https://reprap.org/forum/read.php?245,812355,812472#msg-812472 https://reprap.org/forum/read.php?245,812355,812472#msg-812472 This should help you

It makes the four lines step, dir, enable and ground that are coming from the Rumba available.]]> Srek Allgemeines Thu, 01 Mar 2018 07:50:26 -0500 https://reprap.org/forum/read.php?245,812355,812355#msg-812355 https://reprap.org/forum/read.php?245,812355,812355#msg-812355 That's means, I will use 4 Nema 23 Stepper motor.
