Hi all, i have a problem in y and z axis. ı am using arduino uno+cnc shild with GRBL compiled. .If send command to move only the y axis in both(+/-) directions, z axis goes + direction too at the same time with y axis. and if i try to move z axis only in both directions this time y axis moves only + direction, again at the same time with z axis. btw I used 2 step motor for y axis There are several threads i read from forums but i didnt have a solution for this problem Is there anyone having problems similiar to mine?
My CNC's board specs: Arduio UNO R3(clone) -Microcontroller : ATmega328 Operating voltage : 5V Input Voltage(rec.) : 7-12V Input voltage (limit) : 6-20V Dijital I/O Pins : 14 (6 for PWM) Analog Input Pins : 6 Current for I/O (max) : 40 mA Current for 3.3V output(max) : 50 mA Flash Memory : 32 KB (ATmega328) 0.5 KB for bootloader SRAM : 2 KB (ATmega328) EEPROM : 1 KB (ATmega328)
Arduino Uno Cnc Shield V3 compatible with A4988 (2 stepper motor in Y axis)
And i am sure the connections are in the right places.
i used this project as an example: https://www.youtube.com/watch?v=GsKiz49x8rI&list=RDCMUChrCgXmIW1toX2B7viP6S7Q&index=5
