I was printing on one of our Stratasys Fortus 250mc and I got an absolutely terrible print known as a “spaghetti” print. I’ve never seen this issue before especially with our Stratasys Fortus. I have no idea what would cause this issue. The only thing I could possibly think of is the nozzle got clogged or the filament became tangled or something similar.

If anyone can provide some insight into why this occurred that would be very helpful. Should I attempt to print again and see what happens after inspected the nozzle and related items?

It appears that early on the build your Y axis has skipped a few steps causing the shift in the print layers (looking at your foundation layers they should be completely covered witht he build material).

this can be caused by parts curling off the bed and striking the nozzle. this is most common with rectangular solid fill parts like the ones on the upper left of the build plate.

Do keep in mind that the airflow at the edges of the build plate at the top and bottom are weaker than the middle section and will experience more warping in those zones.You can try nesting the long thin parts running parralel with the airflow in the centre of the build plate. this should keep them hot enough to reduce the chances of warping off the build plate. if you are still having issues, you may try increasing the base oversize value in support parameter to 2.0 or 5.0mm to give more surface area for bed adhesion.

hope this helps

Looks like no support material was printed.

Check that material & support cartridge / nozzles are working.

Shut down the printer and restart it.

Try printing again with a single part to get a faster result.

I once had a software hangup and build material stopped printing after ~20ccm. I reprinted the part 3 times with the same result. As I printed complete parts from the same file before I knew it couldn´t be the gz file. A reboot of the machine fixed the problem.

I would suggest contacting your reseller. Even if you are off maintenance they should help you at least hone in on your options and likely reasons for the issue. If you are in NJ, NY, CT or PA please contact me directly and I will have a technician call / email you (free of charge) to help you determine what happened. You can reach me at jims@cimquest-inc.com

Could be a bed adhesion issue (it’s not sticking to the bed, and then it lifted and dragged the part as the hot end moves).

Personally, I use one for my Hub and it’s great especially given that it’s 1/3 of the price of the 250mc.

Hi,

it looks like there are a couple of issues. It is a bit hard to see from the pictures but it looks like there is a good bit of moisture in your support material. This happens naturally if it has been some time since the machine was used. This could contribute but I don’t think it is the root cause.

These machines are really reliable, but I have seen this same behavior on an older dimension machine. How many hours (standby and build) are on the machine?

As was mentioned in a post before it looks like the Y axis skipped some steps and I have only seen this happen in a couple of scenarios. First is if part of the model curls up and catches on the head.

The second is if the linear bearings in the X,Y stage are failing. If these are failing, you may hear a loud click or pop occasionally as the machine is building. As the problem gets worse you will see build errors like this and eventually machine stop errors.

I was quoted about $5k to replace the stage and opted to rebuild it myself.

Feel free to reach out if the broblems continue.

Good luck
