Update #93

Closed robcop2000 closed 7 years ago

robcop2000 commented 7 years ago

I have tryed to update to GRBL 1.1e. My configuration is Arduino Uno- GAUPS-Stepper DRV 8825. GRBL 1.1.e- bCNC 0.9.7 as controller As soon as I have update I have tried to use jog mode. As soon as I have moved Z axis, the motor turn at hight speed and after stop. Now Z motor is not moving anymore. As a try, I have changed, the motor, the stepper driver, and the arduino board, but the problem is still alive. Any suggestion. Thanks Roberto

@robcop2000 : The upgrade to Grbl v1.1 erases your old EEPROM settings. You'll need to update your settings. And make sure the feed rate used for jogging is correct.

I undestand what you say,but now for me the problem is to understand what has burned. I sedt the correct value but the z asxis doesn't work.

Is not the motor because i chenge it whit one new.
is not the arduino because I flash another one and there is the problem
Is not the stepper motor, because i change it.
I'have tryed to install GRBL 0.9j, but now doesn't work. Maybe is the GAUPS Arduino-compatible Stepper Shield, (I have only one of this) Should be greath if is this, understand which component, so I will try to chenge it. Thanks Roberto

Maybe the driver of the motor?

robcop2000 commented 7 years ago

I have already change

Motor
Arduino board
Stepper motor driver So I assume that can't be the

vMeph commented 7 years ago

What happens if you put the motor z conected on driver x, and the motor x on the the driver z

vMeph commented 7 years ago

Assuming that now the motor x will not work on driver z Dont know that shield but Im assuming you have a4988 or drv 8825 did you ajust the pot voltage on the driver z correctly?

robcop2000 commented 7 years ago

Is not the first installation. The CNC have worked for more than one year. I didn't touch the Driver (are DRV8825). So I assume they were fine. I have only made an update. I will try to change the connection of the motors to test them.

@robcop2000 : Do a process of elimination. Disconnect everything and test by only adding one thing at a time to figure what went wrong. Typically it's not Grbl and hardware related. Also, check your power supply if its maintaining voltage while running.
