I have been using the gshiels/arduino combo for a while now.
I’ve upgraded to larger nema 23s and need more power than the gshield can provide
Hence the need for bigger stepper motor drivers [quote=“NicholasRichards, post:1, topic:33068, full:true”]
I have done research on the forum, google, etc and can’t seem to find an easy to understand/wiring diagram on replacing g shield with tb6600 drivers.
I have 4 of these and wanted to see if anyone has an “idiot proof” wiring schematic.
I just wired a 60a sub panel into my house but can’t seem to figure this out.
The only thing I see is the Amazon page says those drivers are H-bridge drivers and that GRBL page says that GRBL doesn’t support H bridge drivers but I have no experience with these, just reading words.
I’m a little confused about having two for y axis.
Do I need to switch the wires around like how they are currently on the x carve?
I get that i daisy chain the negative wires together to the ground. And same for the power from supply. The 2 a’s and the 2 b’s to motor.
But, The pulse (step) wire for both y axis go into pin 3 on arduino?? And both direction wires from driver to pin 6? And then all four stepper motor drivers Ena+ to pin 8 (Stepper enable/disa) on Arduino?
There;s an excellent write up on stepper motors, drivers and power supplies on the Geckodrive website. They recommend that wiring from the power supply to the drivers should be a star connection i.e. separate wires directly from the power supply connection to each stepper driver and not daisy chained.
The STEP and DIRECTION signals from the Arduino/shield can be directly connected to the Y axis stepper drivers. The TB6600 spec shows shows that input current is very low - less than 1ma at 5V.
Hi Recently I upgrade to TB6600 drivers to stepper with below method of Wiring
steppers moving in only one direction what I am missing I did check every wire connected properly can anyone help me why steppers not moving both directions
I have adruino with 1.0 firmware
X-axis you can connected one TB6600 to arduino (2-Step) & (5-Dir)
Y-axis you can connected two TB6600 to arduino (3-Step) & (6-Dir)
Z-axis you can connected one TB6600 to arduino (4-Step) & (7-Dir)
these are Step + & Dir + to adruino and Step- and Dir- are connected to Adruino ground
If a stepper move only in one direction then 1 of the 4 stepper wires dont have contact.
With only 3 good wires power/step is as normal but direction is lost. Direction will typically be in direction of least resistance.
