Printing Layer Shift_HICTOP 3DP-11

Post by PeterA » October 24th, 2016, 4:36 am

I have a HICTOP 3DP-11 and just recently completed the build. Everything seems to be running smoothly except for the the print layers running along the Y-axis instead of straight up vertically.

I do not think the pulley belt under the hotbed is slipping.

Any suggestions? thanks.

Is that clear filament? I had to really look closely to see what's going on

It is white filament.

Can you share your gcode? If pulley tighted well, it looks like a wrong slicing. What slicer you use?

No, Peter. I talk about *.gcode file placed on your sd card.
P.S. I slice your stl via Cura with "Prusa i3" settings and attach to post. Can you try it?

this is the result using your gcode, with the print still moving along the y-axis.

I attached a link to a video in my google drive so you can view the print in action. It seems to be running smooth than going too fast for the outter layer of the print. Might this be a possible cause for the shift?

I'd check your Y Axis pulleys. You have some movement in there

Here's some more info that might be useful (although the illustrations refer to an Ultimaker)

Your y-axis stepper is skipping. Slow down your printing or bump up the current to your y-axis stepper, or both. For MKS v1.4, there are small pots well marked on the board that control the current to the steppers. Lock the stepper by moving it with the lcd and see how difficult it is to move the bed with your hand. Turn the pot counter-clockwise (i think) until it takes some good force to move the bed. Don't over-do it as too much current will result in overheating and again, skipped steps. Best to use a plastic Phillips-head to make sure you don't accidentally short something out poking around with a metal screwdriver when the board is on.
