GRBL Settings
Posté : 06 juin 2021 23:03
Hi,
I did all steps building the machine, made the main checks for movement and everything works fine as well as I see for the first time.
Except the speed and homing!
Right now I had to setup the GRBL settings and I'm not sure if everything is correct and in this case I want to ask for a basic check.
Reason is I do not understand all of them, even though I read the Grbl v1.1 Configuration on Github many times.
1. Speed:
Cause I build the machine with different stepper motors and stepper drivers as usually (They were include on a complete machine part set)
I had to try out the parameters for steps, max. rate and acceleration for many times until the motors move the desired length.
Now it works but the machine movements are very slow, especially in X and Y axis.
The suggested value in the manual of "4" for the microsteps was not possible with my stepper drivers and I had to encrease them to "32".
I want to stay with the microsteps as low as possible but with values of 4, 8, or 16 microsteps the motors do not move at all or very slow.
What is the right way or parameter to increase the movement speed?
2. Homing
I do not understand the set-up and starting procedure of homing? How can I do that
And I do not even know if the parameters $22 - $27 are correct or not?!
My Grbl configuration is enclosed.
Thanks for help.
