Topic: X/Y axis glitch or software messup?

So i was printing an object was projected to take 8 hours but i thought it would be fine. In the beginning everything was going smoothly until this happened.....

(Pictures in attachments)
I really dont know what caused this.
For some background info:
I have the solidoodle 4
I have had it since August
Using kisslicer to slice
Was printing this: Heatwave 3d Printable Typeface
Here is a picture of this program if it helps


Also i noticed the X and Y motors were hot to the touch but im not sure if that is  normal or not. Also could it be the fact that i need to lubricate the rods now?

Thanks

-Will

Re: X/Y axis glitch or software messup?

Several things to check. I'd check these off in order:

- the alignment of the drive gear on the extruder motor seems to have your filament feeding sideways. You'll want to take that assembly apart and check if the hotend and gear are correctly aligned. Make sure the extruder is not clicking. Do a 200mm extrusion in RH, does it complete without any clicks?
- have you calibrated extruder steps per mm and calibrated to a 0.48 wall thickness? It looks like you are over extruding
- try printing in the center of the bed. The way the SD4 feeds filament stock causes problems with printing in the front of the bed, in my experience. Consider a vertical feed to fix this in the future.
- does the part require supports?

Your issue seems to be inconsistent extrusion. I've seen this when I had issues feeding t glase.

On the motors being hot, if Y is hot, you need to adjust VREF. search the forums and wiki, there is tons of information. X tends to get hot even if VREF is right, so consider putting a fan on it. There are plenty of NEMA 14 fan mounts around.

Also, I notice your temp charts are all over the place. Check your wires for but bed and hotend heaters and thermistors. Sometimes it could be just a wiggle. I had this problem until upgrading to a stronger power supply.

Thanks for the reply i will try all of this when i get back from break as i will be away from the printer. As for the second person with the temps jumping around they have always done this and i even switched out the entire extruder for a new one. The bed always changes within a 2 degree range which isnt too bothersome.

Thanks

Re: X/Y axis glitch or software messup?

You can fix the temperature fluctuations by running a PID Autotune. Temperature fluctuations can affect your prints in weird ways. I haven't managed to make the bed not oscillate a hair, but your hotend should stay pretty dead-on.
