A few things don’t let me rest, with the original firmware (with which the X-Controller arrived), the 0.3.21 Easel driver and the potentiometers in their original state (12 o’clock), everything was fine with the machine , there were inaccuracies during milling, but it fits.
After the driver update (0.4.0), the last rapid movement did not raise the machine to the set original safety height, so it plowed through the material while returning to the starting point.
Corresponding with Inventables, we found that the Z axis does not slip and it doesn’t matter what original safety height I set, it doesn’t raise it high enough either.
I set the potentiometers to 2 o’clock and re-flashed Grbl, as requested by Invetables. As a result, when I want to call the machine home, the Z axis runs for a while and then stops before reaching the limit switch (loud noise from the engine). In the machine inspector, if I manually press the limit switches, I get a green feedback, while the engine hums, it indicates that the switch is not pressed.
I checked the Grbl settings, it was set to $132=100, meanwhile the error in the machine inspector indicated that the Z axis is almost at 150 mm (while in reality it is not), if I changed the $132 value to a higher value , then it’s still a loud noise, but in the machine inspector it showed the maximum Z value again. When I changed $27=1,000 to 5, the situation only got worse.
These are my settings:
$23 = 3
Does anyone have any ideas before I change the wires?
