So - I need some help. I’ve had a very odd thing happen on my second Solidoodle 3 printer. The first is fine. The second one has been turning out cameras for my Kickstarter like clockwork. In the past two days, it has turned out 4 consecutive identical problematic cameras - they look great in the front. In the back, they are much rougher (see photo). I thought the first was a fluke but now I have four, all the same.
The belts are tensioned ok. Even if that was the issue or the stepper was having trouble, the front would be a mess too. It’s the same sliced g-code file with no changes (30+ good runs). I’ve turned it off and on and rebooted the PC driving it. All the sides and the top are enclosed and it’s sitting in a relatively stable (tempwise) enclosure. Same thing - smooth in front, rough in back (on the Y axis).
Has anyone ever had this problem? I can’t understand it. It seems the Y-axis has an issue but only on the back side of the print.
More: the base is on the bed and the bellows faces the front of the printer.
All parts are still tight? Only thing I can think of is some connection loosened up.
Seems so - I would expect the front to mess up as well if belts were loose or a pulley slipping etc. I might move it on the Y-axis to see if there’s something specific about that area - can’t think of anything else to do.
Maybe a part overheating? Check all connections? Rotate the part, see if the same print area has the problem.
I was referring more to the printer’s structure than its moving parts.
At first I thought it was a slicing error, but actually I think it is overheating. The print is still hot when the next layer starts so it deforms.
Also check your acceleration settings.
So two things to try, slow down your print, and slow down the acceleration.
Well, all good suggestions. First, it printed 30+ good cameras and then 4 went wrong but only on the back. All using the same g-code file and extrusion/bed temps. I agree though, something must have changed. The front is fine so the printer is getting to the right Y coordinates on the front. Any mechanical issues (belt, pulleys, motor overheating, etc) should cause the front to mess up as well. It’s a Solidoodle so it’s not lack of a rigid frame. The Accel/jerk settings haven’t been changed.
Think I will try @Jarrid_Kerns suggestion first and rotate it front to back. If it’s a printer issue relating to that area of the Y axis, the back should now be ok and the front messy. I’ll have to reslice so two variables will change. I’ll have a new print in the morning (6 hrs).
@Matt_Kraemer1 , I’ve got a different issue at the moment but I do see a bit of ghosting and will try reducing Accel/jerk later. Since I had 30 good prints before this, I need to find out what changed and then I’ll try this.
Hmm, I rotated the print front to back and it printed ok without a rough side. I’m printing again in the original configuration but resliced and using 25% lower accel/jer
Jerk. No, not you, just completing my escaped comment.
