Huge issue need help ASAP (Page 1 of 2)

Honestly it seems like it's a software glitch, but still, I need it to work

The model has been run about 15 times flawlessly. It all started whe I tried to run a new model. Ran it through Cura, and it started messing up. Ain't been right ever since. Weather I print it from the SD card or the computer. Any troubleshooting suggestions??

Okay I'll try it

So it is Cura causing it. I could not get the Cura slicer that is built into Repetier host to ever work right. But if you Google Cura you will find out they have a host that the Cura slicer id built into. It seems to work much better.

Yes and considered open source. I use it more than RH now.

For this version of Cura you have to make changes then save them under file and save profile. The you have to open that profile to get the settings to come into the system. You can't change them on the fly like you could in the RH version. This way you can set up different profile for different filaments and colors and parts and load them each time you switch to one of those changes.

You are probably printing with the default settings they where loaded when installed and none of your settings have been made yet.

You don't have to close it, just make your settings, then go to file and save profile as and name it whatever. I keep mine on the desktop so it's easy to find. The just go to file, open that same profile and it will load your settings then. Once you do that it is good to print.

I have a pretty new printer with about two weeks worth of printing on it (1.0a flavor) and it starting shifting prints like this and after much testing it turns out that the wires plugging into the stepper motor on the side were rubbing back and forth on the plastic wall near the hand hold, and as those wires at the plug (for the motor and end stop sensor) wiggle back and forth it would cause my prints to randomly shift.  I tried swapping the wiring harness between the X and Y steppers to test this and got the same random shifting on the same motor.  So I think it's the plug on the stepper motor that is loosing connection as it wiggles rather than the harness.  I removed the plastic wall on that side and pushed that side up against the wall so it's not wide open, but nothing there for those wires to rub against and haven't had any issues since.

Eventually I'll probably replace that motor with one that doesn't have this type of connector, or maybe just open it up and solder the wiring harness into it.

Hope this helps!

If you are looking for a top infill that looks like your bottom infill you will never get it. What exactly are you looking for in a top infill? It will never be as smooth as the sides. The top will always look some what squished or spread like icing on a cake. I have yet to see a printer under 1000 bucks lay top layer lines side by side like it does on the sides. It always squishes them based on your layer height. Now I suppose if you know exactly how many layers you have and your host allows it you could set it so the top layer is printed at a thickness very near the nozzle diameter and then it wont squish and blend the line together.

This is what it looked like

The black is cura in Repetier, and the yellow is slic3r in Repetier. See the quality difference?
