I am having a problem with my Vertex K8400 3D-printer for a while. Sometimes it just refuses to move it’s z-axis upwards. When I select control printer > move axis and then try to move the z-axis up, it moves downwards. When I try to move it downwards, it also goes downwards.
The same occurs when I try to start printing: when calibrating, it moves all the way down (where it normally moves up towards the nozzle) until it jams and I have to stop it.
This problem occured a few times earlier, but when I restarted and resetted it a few times, it would resolve itself. But now, even after restarting and resetting several times, it won’t go up.
Does anyone know this problem and/or have a solution for it?
Thanks. I just cleaned it, but I keep having the same problem.
I use Control Printer > Move Axis > 0.1mm > z-axis and try moving it upwards. When turning the button anti-clockwise, the z-axis moves down and the LCD-screen displays an increasing Z-coordinate. Moving it clockwise makes the z-axis move down as well, but the LCD-screen displays a decreasing Z-coordinate. When the Z-coordinate is all the way down to zero, the axis doesn’t move while turning the button clockwise. When turing anti-clockwise the process starts all over again.
I also deconnected the thread from the motor to make sure nothing is going on in the end-stop (because this will hold it from pressing the end-stop), but this gives the same result.
Do you have any other ideas what might be causing this problem to occur?
