So I haven't used my printer in a couple weeks, been out of town. Today I start working on some projects and for some reason the printer is shifting every layer about a mm every layer so that my objects are crazy deformed. It's not my slicer, I've used a couple, belts are tight. Anyone have an idea even where to start?
I just ordered one of these printers and plan to modify it. Can you tell me if the power supply is 12 or 24 Volts?
The power supply has 3 12V outlets.
Hello everyone, I've assembled my FlyingBear a couple of days ago and I have a problem, it prints very well the first 5mm in height, but then it starts to generate weak layers randomly every 2mm or 5mm. When I manually check and move the Z axis I noticed that the shaft does not move smoothly, but it goes small jumps when it goes down, I disarmed that axis completely to review it, I greased it, I adjusted it, but it continues with the problem, although not so frequent. Has anyone else had a problem with that and could have solved it? I hope you can help me with this, thank you very much.
Maybe the problem is coming from the Z bearings? try oiling so it goes smoother (grease sometimes is too thick). Hope it helps.
Thanks for you response alvarez86, the problem is actually in the X axis, but not in the bearings but rather, one of the steel rods does not slide smoothly, I disarmed the entire mechanism of the Z axis and tried both bearings with both rods, but one of the Rods is very tight on the supports and does not slide well on the bearings. I hope the people of Flying bear solve the problem, I'm trying to contact them.
Contact them, the first month of having my printer the arduino fried when I first connected the printer to the PC, I contacted them and send me a brand new one (I took 2-3 weeks to arrive).
SO found the issue I think. Turns out the Left/Right motor (I was saying y but it links like software-wise thats x?) had a pin loose on the pulley, it was just loose enough to cause the problem. Weird but I think it's fixed now. Doing some test prints to see.
Glad you got it fixed! Good find!
Yes, I feel dumb not catching it sooner but I was just about to tear it down completely because I knew it had to be mechanical.
There are lots of people on the facebook page that would be able to help, theres a group specifically for Flyingbear owners!
Are you printing from USB or from an SD card? I read that sometimes USB connection issues can cause stalls in the print which could creat shifted layers. If you are, try printing from an SD. Here's a generic list of possible causes/solutions http://reprap.org/wiki/Shifted_layers
Have you tried re-leveling your bed? a few days ago I caught my cat sitting on the bed. I wasn't getting shifting layers, but I definitely had to re-level. Maybe it's as simple as that?
Several things come to my mind:
