I am losing my mind! I have a pretty decent understanding of 3D printers, but for some reason I cant figure this one out. I can do a single color/material print, and it works perfectly fine; however, when I try doing a multi-material/color print, the printer will print the first color fine, but as soon as it switches colors, the bed shoots forward and gives me the y-axis error. I’ve tried 3mf files and stl files, but it does the same thing no matter what. I really don’t understand why this is happening, but it’s very frustrating. I dont change settings, and I always make sure my printer is correct before sending. The printer is clean and free of debris on the y-axis rails, as well as no obstructions preventing the bed from stopping. HELP!
How did you slice the file? With the current Creality Print version on PC? It’s more about the GCODE not STL/3MF probably. You could look at the GCODE file to see if there is a strange Y axis movement close to the filament change or if it’s coming from the printer itself.
I’m on Creality print 7.1 for PC. I was looking through my GCODE, but didn’t really see anything out of the ordinary either. Maybe there’s something I’m missing. This issue is relatively new, as I’ve already done multi-color prints with no issue.
Here’s my gcode for filament change:
