I added a new Flashforge Creator yesterday to my production line to make three. I ran through the first few prints without trouble, then went to add a glass print bed and forgot to lower the build platform properly to account for the increased height. Anyway, when I went to level the build platform the extruders slammed in to the glass print bed and got caught, sitting there and chattering and jumping and making all sorts of noise. Fortunately I was right there when it happened so I was able to shut it down right away.
Unfortunately what this seems to have done is screw up the proper starting point of my Y axis (X axis seems unaffected). When it goes to start the purge run at the beginning of a print (which it usually does from right to left at the front of the print bed), the Y axis is about 20 mm off placement towards the back of the machine. Clearly the belt must have been slipping when the print head got caught and now the machine thinks the carriage is in a far different place than it actually is. Anyone have advice on how to fix this? I’ve looked around in the menu settings and all I can find is home offset and toolhead offset. I’m not certain either of these would allow me to change where it thinks the Y axis is.
Look to see where the spring is on your y belt, when it is home(Back Right) the spring should be on the top belt loop about 3"-4" from the front. This spring may be causing it to jam up when it goes to the front position if the belt slipped.
Thank you for that advice. I’ll check that when I get back home this evening. I played around with the offsets in the menu but none of them seem to do anything to change the Y axis starting position. The only way I can get it working thus far is when the extruder moves to the front left to begin its preheat, I manually tug the extruder assembly forward so the Y Axis is lined up where it should be. After I do this, it’ll print the model just fine from the correct positioning. But I imagine it can’t be good for the machine in the long run, so I’ll check that spring to see if it’s jamming.
Other than this 3-4 inches is there a more accurate test to make sure your on target.
like perhaps a target that would attach to the build plate and show possibly how to centre it .
kind of like a test print from a jet printer lol.anybody.
Did you ever figure out what the issue was?
Not really. It sort of just self resolved [shrugging shoulders]. I manually forced it in to the proper starting position several more times and it eventually just fell in line I guess. No problems since then.
Well with machines you would mark your belt and make adjustments from there.
So probably need to find out what material belt is so not to harm that.
. But good job on manual repair . You the man. Lol
The stop switches set the range of each axis everytime a print starts, shouldn’t matter if a belt has slipped in the past.
Thanks for the chime in , awesome news.
Thanks for sharing. Im new
