Re: Problems with Top Layer. - 8 years ago
QuoteMCcarman As you were printing at 190c we assume your using PLA so 230 is way to hot and explains the brown marks and the stringing. So I would set it back to 190. Then you check if you can push the filament through by hand. If so the issue is the extruder as O-lampe has pointed out. From the picture it looks like the idler arm gets very close to the mounting block so check you have clearanceby Bretta91 - Printing

QuoteFloyd looking at picture 4210 you have no hot end cooling fan for the fins! YOU NEED a fan there! I does have a fan, but is in the back, I printed this mount (https://www.thingiverse.com/thing:432000), so I can fix the e3d hotend to the Rigidbot.by Bretta91 - Printing

QuoteInhumierer For me the right cap looks better. On the top it looks like a little underextrusion. And 230 deg is AFAIK way too hot for PLA. Did you adjust Vref on your drivers? Checked the current to the steppers, especially the extruder stepper? Are you printing with 3mm or 1.75mm filament? What's your nozzle size? 3mm filament and 0.3mm nozzle can be hard work for the extruder stepper. Do yoby Bretta91 - Printing

Hello and thanks for all of your responses. Unfortunately, I keep getting the same problem, and I really don't know what could it be at this point. I've already change the extruder for a brand new e3d Lite v6 that I bought from reprap.me (http://www.reprap.me/lite6-full-kit-1-75mm-universal-direct-12v.html). As I had to change the thermistor settings in the Marlin firmware, I change it and thenby Bretta91 - Printing

Hello to all, My name is Richard, I'm new to this forum and first, I like to say Thanks!! to all of you. I've been searching for answers in this forum since back in 2014, when I first get my 3D Printer, a Rigidbot Big by Invent-a-part, and all of you have been a valuable help to make my prints better and for troubleshooting my printer. And today is the first time I'm asking for direct help beacuby Bretta91 - Printing
