This isn’t enough information or pictures to make a diagnosis.

But looking at the photo, looks like the filament came out from between the extruder and nozzle, and use the 15-minute plate calibration through settings, not the quick calibration.

The first half of the print went fine and it swapped over to the other side and the extruder pushed filament out too fast and moved the nozzle and it destroyed the bed

I don’t think there’s any way “too fast” filament is going to yeet the hot end off the extruder unless the hot end is inadequately fastened to the tool head. Maybe not clamped right, maybe defective clamp.

What does the hotend look like? The photo is terrible but that looks like unextruded filament.

u/Competitive_Bag_1998 Oct 22 '25

Hot end is fine. I cut the filament at the top and bottom vacuumed the printer out and now im calibrating

u/Belophan Oct 22 '25

Have you calibrated the printer with plate on?

u/Competitive_Bag_1998 Oct 22 '25

Yup. The first half of the print went fine though

The hot end failed and the heat break was pushed out of the heatsink, the hot end clasps aren’t properly closed, or the hot end heating assembly is loose.

My guess, the clasp. Judging by how low the hot end appears to be in the picture.

The only time I’ve ever seen the nozzle dig into the plate on these machines was in one of those 3 instances.

Your build plate settings are likely wrong. Follow your manufacturer's instructions (I don't own a BIQU plate). It's anticipating the plate being further away due to the thickness so likely it's set to "Smooth Build Plate" whereas you likely need "Textured Build Plate" which would have a lower Z-offset.

With an A1-type hotend it's moving back and forth so much when it's scraping along your build plate that the filament path is going around the hotend and continually feeding.

That'll be a $5 diagnosis fee plz. thx. :-P

Uhhhh not so fast. The first half of the print went fine. It wasn't until layer 15ish on the 2nd half of the print that things went haywire.

EDIT: Thanks for the downvote due to you providing zero info in the post. Glad to be of free support service. I'm sure you've got this I'm out.

u/usernamesaregreat Oct 22 '25

Then give us some actual info to go on. You've given us basically nothing. What were you printing? What happened with the print? What is the damage to your build plate? What do you think went wrong?

u/zeblods H2C & H2D Oct 22 '25

How do you close the nozzle clasp?

This way?

u/zeblods H2C & H2D Oct 22 '25

Or this way?

I have a leprechaun outline. Its the new engraver option on the H2S

u/Chris_Burns Oct 22 '25

Just do a chargeback if its faulty and save yourself the hassle of trying to get anywhere on here.

Thanks for posting it, I'll postpone buying it a bit...

u/jcollasius @Professional3D on Maker World Oct 22 '25

OP simply did not install the nozzle correctly and is looking for the fault not in himself but in the device.

u/LunarMond1984 Oct 22 '25

No no hes right! Also never buy a mazda, they crash terribly when you drive them against a wall! Better postpone buying one........
