Axis moving slowly but good in stepconf was created by rajsenthil
Hello, I am a newbie trying to configure the linuxcnc 2.7.8 for the TB6560 driver. The stepconf test run is working smooth and good but when I run using the Axis, the motor is running really slow and gives a grinding sound. I tried to read threads posted on this forum and try to figure it out but so far no success. With the current slow moving, the machine is not useful for any operation. Please find the attached configuration files including the ini and your feedback is appreciated.
Thanks
Thanks

I note that your default velocity is set to 2.5 in both [TRAJ] and [DISPLAY]. Is the problem just that you need to move the sliders up a bit?
The INI settings are described here: linuxcnc.org/docs/2.7/html/config/ini-co...tml#_display_section
The big difference between the test in the config wizard and running inside Axis is whether the drive-enable pin is connected or not.
Now, you would expect that to just be a drive that doesn't turn on, but there is also the possibility of mis-wiring so that the drive is turned on and off at the step rate. Which can sort-of work, but badly.

Thank You very much, I changed the velocity value to 20.00 and it works well now.
