The universal g code sender recognizes my Arduino and lets me connect to it. However I cannot get my stepper motors to sync with G code sender. My stepper motors act erratic and do not respond to my commands. I will tell you my setup and any input on how I can get my setup to work would be greatly appreciated.
I am using a MacBook Pro with OS X Yosemite.
I flashed my Arduino Uno with “grbl_v0_8c_atmega328p_16mhz_9600.hex” via Hexloader (https://github.com/paulkaplan/HexUpload … exUploader)
I am using Universial G code sender (GitHub - winder/Universal-G-Code-Sender: A cross-platform G-Code sender for GRBL, Smoothieware, TinyG and G2core.)
This is my exact breadboard wiring:Attached.
I am using these stepper motors Lot of 3 Stepper motors NEMA 17-DIY (http://www.ebay.com/itm/121158802114)
With these Easy Drivers: (http://www.ebay.com/itm/3pcs-A3967-Sold … 1608590147?)
This is the power supply, 12v 1a: (http://www.ebay.com/itm/271612243500?_t … EBIDX%3AIT)
( I cleared the arduino with the romclear code many times and re flashed it trying to get it to work)
Any help would be greatly appreciated!!! Thanks.
