I keep having my printer give me ams motor overload problems, on all slots, tried with different filaments, now even tried a different ams, there are no jams to be seen, spools moving freely.
After this if I tell it to resume it does but I hear it miss a step and then start printing mid air even though the filament is flowing properly.
Please someone help
When asking for help, please provide as much information as possible about your inquiry.
This will help everyone to better understand your problem, and provide you with the best solution.
- Detailed description of the problem
- Printer model used
- Slicer settings used
- Type of filament used
- Photos that clearly show the problem
- .3mf file (if the file can be shared)
- Any potentially useful information that is related to the problem
My apologies
Printer H2S
The problem is it starts to print barely even starts the first later then stops with motor overload, pull filament back and starts again but then misses a step and starts printing mid air
I have tried multiple files and does it with all of them. Files that have previously printed perfectly fine.
I have tried multiple different filaments, all various types of high speed pla, again which have been used previously with no issues.
Sometimes it does something different, it starts printing and doesn’t report any problems but just starts mid air.
I’ve checked the routing of ptfe tubes for any tight bends and there are non, I have tried a different ams that works fine on my p1s and this still has problems so assume the ptfe tubes are fine.
I can’t get my head around what is going off.
Managed to get one successful print earlier that previously had failed with the same issues but tried again and it worked but since I have tried 10 different prints and it is still doing the same thing.
I have also tried restoring factory settings and re calibrating, after this I printed a benchy and it printed fine, but since then no luck.
Thanks
Sounds like you might have a partial nozzle clog. Try swapping the nozzle out to fresh one. If this fixes it then you might be able to recover the old nozzle by doing a couple of cold pulls. The printer will walk you through the steps to do this.
Thank you I will give this a shot
Fingers crossed it works. It’s only 2 weeks old lol
So I havent changed the nozzle yet.
After a full calibration I managed to print a benchy then a massive print however on the big print it did stop multiple times to pull back the filament and try again, each time it recovered ok.
I did notice that the filament buffer is clicking a lot and saw that it’s a common issue. So I’m printing a fix for it and going to see if that makes a difference.
Do you think this could be it?
Sure sounds like a clogged nozzle as Jon was saying
Yeah this is my next move. Will post an update when I get chance to do it.
Yup sounds like a clogged nozzle.
This is a really terrible practice overall.
First, understand that these printers normally work extremely well in their bone stock configuration.
When there’s a print issue, it’s important to diagnose it correctly and get to the root cause of the problem, rather than trying to correct symptoms.
Your buffer isn’t the problem, it doesn’t need fixing, printing fixes to change how it behaves is not the answer, and this overall behavior wastes time, money, and can introduce even more issues - and frustration. Most of these “fixes” floating around limit or reduce the function of parts of the printer and often make it worse than stock.
The buffer is meant to react to changes in filament feed, if it’s clicking a lot that means you have a feed problem.
Change/unclog your nozzle like Jon suggested, and you should check your PTFE feed path to make sure it’s as free of resistance as possible. Chances are extremely good the buffer clicking goes back to normal at that point.
Thank you so much. I think I just got lead down the wrong path when I googled it and saw it’s an issue. But you saying feed issue makes complete sense as to why it would click like it does. I’ll hopefully get chance to go swap the nozzle this evening.
Thanks again
And thanks to everyone for your help.
I looked at those buffer “fixes” and they’re meant to address a very specific issue - on some early H2 units the PTFE was a bit short, so when printing at the very front of the bed the PTFE was pulling the buffer abnormally and starting to kink, causing that clicking misbehavior - but the rest of the bed would not have this issue.
I don’t understand why people are printing fixes for it at all to be honest - they just need to install a longer PTFE tube, these “fix” parts actually make the effective length of the PTFE even shorter, which will increase the chances of kinking the tube. Totally a fix that can actually make things worse in the long run.
If it’s not your nozzle please let us know, I have a few other troubleshooting steps to try!
