Re: Baffling problems under the microscope

Sounds like maybe you have accidentally adjusted Tune>Flow> to very very little.

Re: First layer issue (wrinkled)

This is a common issue. Mostly harmless, usually gets covered well by the next layer and the underside is smooth anyway. It is caused by too much filament extrusion for the layer height, so the excess has to go somewhere and the only available direction is 'up'. It's most intriguing how it forms the...

Re: Nozzle too high

Check if the PINDA probe is 'triggering' way too high up.

You can tell by the orange light on top of it. It goes out when it senses proximity to the metal parts in the bed.

A broken PINDA cable can sometimes cause this. Intermittent contact can cause baffling behaviors.

Re: I3 goes crazy and finally bricked..... HELP !!!!

I don't know much about dead Rambo's, but before that happened, the problem sounded a lot like a broken PINDA cable.

If you get the printer going again, pay attention to the orange light on top of the PINDA probe.

Re: really FAST profile?

You can get the 40W heater element instead of 30W.

Re: Week old printer with extruding problems

I think you might have inadvertently misadjusted the idler tensioning springs on the extruder.

Check if they are set to 14mm when empty, and 13.3mm when filament is loaded.

Re: Baffling problems under the microscope

Success at last! No weak blob lines in the entire fin, although I used the most difficult material that I have tried for this purpose: Transparent PLA. It appears to be harder than other PLA filaments and harder than the BioFila filaments. This hardness makes it less forgiving when the idler tension...

Re: Apollo X ASA filament - any experience?

Apollo X does not seem suitable for printing large objects prone to warping. I managed to find a heat bed setting that allows removal of the ApolloX from the PEI sheet: Start with bed temp 30C, increase to 90C from 2nd layer. I finally decided to try printing a fin using ApolloX. The fin tore itself...

Re: What is the blue nozzle shroud called

Looks like they improved (or at least changed) the silicone sock. The hole for the nozzle is much larger now. Probably good, that part deteriorates fast anyway. I might try to 'adjust' my old socks by cutting away the burned bits to make the hole bigger. However, the larger hole does leave a larger ...
