I have a Prusa i3 printer with a MK8 hot end and I have started to have print quality issues, My first prints looked really good but they are starting to look pretty bad. After I noticed this issue I started to inspect the belts and bolts for tightness and I did find that one of the bolts that hold the hot bed to the Y axis table had come out, I replaced the bolt and tightened all of the belts thing I had found the problem. I did a print to test and still have the problem, The walls around certain features (such as circles) look very strange with a “noise” in them. Also, It isnt pictured here but the corners of any box I print look shakey and not smooth and square. Any ideas of what is going on?
Here is a picture of the “noise” I am talking about
Here is how it is laid out on the print bed
And here are my print settings
Any help I can get on this would be greatly appreciated! I can provide additional information if needed (sketchup files, .dae files, .gcode files ETC.)
Check out this link, it really come sin handy diagnosing printing issues. I think you should specifically look at the “Vibrations and Ringing”
https://www.simplify3d.com/support/print-quality-troubleshooting/#vibrations-and-ringing
There is also the possibility of a thermal cut of your stepper controllers. What is the controller board you’re using and is it ventilated ?
You are getting alot of ringing on your print. Generally this means that something is loose and vibrating in the printing, it’s probably audible during printing. It may also be misaligned parts that are not able to move smoothly. Lastly it may be that you are printing too fast.
Yes, when the y axis moves to the negative direction I hear a vibration. I did find that the y axis belt was rubbing against the bearing bracket pretty bad. Gonna make a belt guide to go around the bearing to try and help with that. Plus the print bed is on springs and vibrates when it moves faster or doing fill in walls. Going to add an auto level bed to it to get rid of the springs. But I’m having a hard time locating the firmware to download for my printer and I do not want to get the wrong thing.
I’m not sure if the springs are your problem. You should try taking the y belt off and moving the bed back and forth. It should move with no friction and very tiny vibration at the most. If not then one of the rods is misaligned or the bearings need to be lubricated or the bearings are bad.
Thanks! I will leave the springs for now, I am about to draw up the different bearing brackets I need to the y axis belt and I will check into the rails being perfectly parallel, do you guys have any tricks for doing that(making the linear rods parallel)?
What I do is loosen up both ends of the rod holder, and then slide the bed back and forth until there is very little resistance. Then I tighten down the holders while checking to make sure the bed can still slide smoothly.
Ok, So I contacted Hictop to get the firmware. They sent it to me without any problems but, I was expecting a file that I could edit in arduino IDE but they sent me a a .HEX file. I now have no idea what to do with it, There is not a separate arduino board on my printer only this

I am wanting to modify it to use an auto leveling bed but have no idea what to to now
Ok so I downloaded this GitHub - ErikZalm/Marlin: Reprap FW with look ahead. SDcard and LCD support. It works on Gen6, Ultimaker, RAMPS and Sanguinololu I can edit this with arduino ide to enable autobed leveling. Will I be able to load this onto my printer?
