Parts need checking, wrong size

Had typed a lot out but page crashed, tearing hair out to find out why this thing won’t print turns out the splicer had a tube that was 1.85mm and the 4 spares were all 1.76mm.

Thus causing all of the blockages that resulted in the pings dropping off.

Give the old splice tube a measure and voila therein lies what i hope is the easy fix but so frustrating.

Rest of the spares were all 1.75mm.

Hey Dave, let me chat with the hardware team about this and I'll get back to you. Apologies for any delays as some of our team is unavailable during the holidays.

@fishpig that's really interesting. Thanks for posting this. I've never had a clog in my BMG extruder using Slice's Magnum hotend until using it with the P3P. The enlarged splice point may explain why my drive gear skipped on the filament to a point where it ground enough off and couldn't feed anymore. The splice was larger than the hotend opening. The most recent occurence was when it happened while I was trying to print utilizing the new multispool/runout feature. The P3P spliced 3 spools together successfully and then the filament skipped in the extruder because it couldn't feed into the hotend. I came back to the print 5 hrs later and it was air printing about 8 inches above the print. The P3P was still running waiting for the printer to pull filament so it could create more but the printer wasn't pulling any. So the P3P was working as expected. At first I thought it was a broken splice but it wasn't. I can honestly say, the splices my P3P produces with PETG are rock solid. They always have been. But after reading your post I'm leaning hard this is the cause of the problem with the pings falling way out of calibration and the P3P aborting when they fall below 50%. Skipping filament would certainly cause that and print calibration issues on non aborted prints. I'm going to measure my tubes and see if I have the same issue. Thanks again.

Yeah I'm printing ok now, just using multi spool to join all the waste into 1 roll and so far it's yeah well working.

I do wish the multispool would pause on empty filament instead of cancelling

Hey Dave, I spoke with our hardware team and 1.85 is within our tolerances for splices (+/-0.1mm). What size heat break are you using? If it's too small, this may be causing issues.

my heat break is an E3D V6 and since changing your splice core tube things have been fine.

Maybe you need to change your tolerance settings because it seems like a few people are having the blockages and low pings.
