Well done Greg, that truly is a wonderful print. I'll have to try the new High-res version. We really did have a fantastic set of prints this week can't wait for the next challenge...by richrap - Competitions

J-Head jamming every day for 10 days straight - 13 years ago
I had a recent bout of blocking in my J-head, but it was contaminants in the Plastic - if you think you have a blockage, push up a pin while applying pressure to the filament while its at temperature, if material starts to come out, then you probably have something blocking the nozzle inside. - just check it's not ball bearings! - http://richrap.blogspot.co.uk/2012/06/jammed-frggn-nozzle-30doc-daby richrap - Reprappers

Re: fan causing heated bed to warp prints - 13 years ago
You can easily have the heated bed too hot for PLA, nothing will stick at 90 degrees C I usually find that some colours may not stick at 60 - 65 degrees, but if I lower the temp to 55 or even 45 degrees they stick just fine. I usually start with 60 and work my way down, not up. Also try glass cleaner with Vinegar, seems to always work for me, If I use 'Astonish'Glass and tile cleaner, nothingby richrap - General

Hello everyone, Have a great time at the weekend, sorry I can't make it, but It's my daughters birthday party. But I do have a venue we can use in Stroud for any weekend in July - I have been watching the dates flying in, so I wanted to add an event and attempt to fit-in with the dates already taken, maybe I should send over the details to Hamish if that's ok, and you can discuss a suitable dby richrap - West of England RUG

Re: KickStarter Campaign For Dual Extruder - 13 years ago
I also saw a replicator operating last month, and it was not doing a great job of handling either one or two extruder's, but I expect that was down to the way it had been setup. I was also rather shocked how slow it was printing, especially the first layer, that was going at about 5mm/sec. Maybe printing reasonably fast and drop the temperature of the non printing extruder back by ~20 degrees, yby richrap - General
Re: KickStarter Campaign For Dual Extruder - 13 years ago
I decided to go for the dual kit with resistors a few days back, it looks like the MK7/8 so should work ok, I'm not a fan of direct drive, but it's quite a nice setup for dual extrusion and very reasonable cost, it's looks like they are doing very well with the campaign, so should be able to get these machined nicely.by richrap - General

Re: Is the Heat bed tape needed? - 13 years ago
Use 3mm or 4mm Mirror-glass (a mirror) for PLA, clean it with 'window cleaner with vinegar' NOT IPA or Acetone. - 45 to 65 degrees C Use 3mm or 4mm Mirror-glass covered with PET Tape for ABS - 95 degrees C or hotter Try to use Bull-dog clips to secure the glass to the heated bed, or Kapton/PET tape if not.by richrap - General
