Hello everyone. While the X and Y axes are in motion on my P1S printer, I noticed a slight movement in the Z-axis. When I increased the print quality in a specific area of the model, I observed that at -0.08mm, the nozzle rubs and collides with the previous layer.
I’ve done some research here, and it seems some people experience this issue as a software-related problem. The firmware version on the machine is 01.04.2. I will upload the videos as a link.
Additionally, when I checked the tops of the front spindles, I encountered a situation similar to the one in the photo. I would appreciate your assistance on this matter. Thank you
Are you sure the Z screw isn’t moving to compensate for a not so perfectly leveled bed?
I believe it gleans this data on the 16(?) point bed check before each print.
It then uses this data to move the bed ever so slightly in an effort to fix inconsistencies in conjunction with the X and Y.
“A nice theory, but I don’t agree with that. If it were a proper machine, it would know not to collide with the previous layer when printing at a 0.1 mm quality. :D”
So you are using a 0.2mm nozzle when printing at 0.08 layer height?
At that height a 0.4mm might be too large. Depending on your settings, it may be over-extruding and there’s no way your printer is going to “know” that the layer it applied before is taller than expected.
And a little more thought on the matter… It will “z hop” depending on line starts, wipes and such.
This would be the Slicer’s doing, not the machine itself.
A good way to see this is to print a wide model with lots of straight lines and at a very slow speed.
You will see the z axis moves corespond with the lines start and end.
The stepper motors “full step” is in increments of .04. It can do mid steps but isnt as accurate as a full step. Its usually 1.8°, or 200 steps per 360°
