Re: Mid-print extrusion stoppages and replacement parts

Also, I've found that lubricating the grooved filament guide wheel on its bolt/axle, once it's properly aligned, will also help with smooth feed, and get rid of grinding.

I've set retraction at 4.5mm, and retraction speed no more than 2700 mm/min or 45mm/s.

Re: Slow/failing heater, faulty temperature sensor, grinding extruder

BVC is sending me a replacement sensor. In the meantime I've greatly improved my right extruder which was all I had left available to me, and learned a lot in the process! :) The grinding has been resolved by a combination of checking the extruder alignment (as per forum post) and using the washer-i...

Re: [IMPORTANT] Maintenance - lubrication of the guides and thread rods

I would add that it's well worth adding a drop of 3-in-1 oil to: a. the axle of the filament guide wheel (the one that pushes against the knurled feed wheel) b. the X and Y axis belt bearings (opposite end of the belt to the stepper motor) Oiling point a) can help with filament grinding if your guid...

Re: [INFO] Confirm your extruder alignment

I can confirm that this modification improved the alignment on both extruders, and reduced grinding on the one that perpetually ground the filament.

Re: [3D PARTS] Source files for helloBEEprusa 3D printer KIT mechanical parts, including the printed ones

I've loaded up the files in Freecad, and it seems the gaps are around the same size as what I printed. So it looks like the printer body has changed dimensions at some point. The stability feet here http://www.thingiverse.com/thing:1080908 are the correct size (3mm gap) and fit perfectly. Having tr...

[SOLVED] Slow/failing heater, faulty temperature sensor, grinding extruder

I have multiple problems with my hBp... 1. When the machine is cool, at room temperature, the display shows 21 degrees for the right extruder and 10/11 degrees for the left one. This is clearly wrong, and it's the left one with the wrong reading. Presumably this isn't something that can be corrected...

Re: New hot end needed

Thank you very much to all who responded. I eventually cleared the nozzle by the blowtorch method, and by altering software settings and avoiding filament that feels wrong, I've not had further clogs that I can't clear in-situ without dismantling. Case closed.

Re: [3D PARTS] Source files for helloBEEprusa 3D printer KIT mechanical parts, including the printed ones

Paul,

If the slots are too small in both x and y planes, you're probably over-extruding and should reduce your extrusion multiplier slightly. If it's just one plane, that would indicate mechanical slackness, for example due to a belt that's too loose or even a belt wheel that's slipping.

Re: New hot end needed

Thanks for the reply & helpful advice, Tizz... Unfortunately I can't even unscrew my brass nozzle from the steel feeder tube, and the grub screw securing it into the aluminium heater block won't seem to let go even once unscrewed completely. Once again, it's all completely different from the other e...
