Re: nylon filament

Nice piece. What nozzle and layer height were you using?

Re: Alternate support material suggestion

I just used d-limonene for the first time. I had (notice the past tense!) 10 ABS parts printed with eSun ABS yellow. They took two days to print. I soaked them in d-limonene to remove the support in the two o-ring grooves per part. The HIPS did dissolve, but the parts expanded and deformed to the po...

Re: Simplify3D Offset Issue

Andy, many of us print dual extrusion with no problem daily using the N2 so I'm a bit baffled by your comment. Perhaps you could clarify why you would never buy a R3D N2 to do dual extrusion? Are you saying it is incapable or that there are much better machines to do this sort of work? I currently u...

Re: Power back up for raise 3d n2 plus

I'm not sure why you are using the word "inverter" here. Are you looking for a UPS? When running the N2 uses about 450 watts per hotend -- but that varies significantly up and down as the controllers turn the heated bed, hot ends and motors on and off repeatedly. I figured going with an AP...

Re: Bondtech BMG upgrade for the N series

As a hope factor for anyone still having a struggle with the new BMG: I have been very successfully printing ABS with HIPS support, eSun ABS+, and some Polymaker PLA+ on two N2s. I keep them printing as close to 24/7 as I can. Once I got the support extruder calibrated into Simplify3D, these extrude...

Re: Bondtech BMG upgrade for the N series

Look back at my posts on the same subject. I solved it. I found that the motors were getting way too hot with the cover closed during ABS printing. I have not had a clog since I simply started venting the air temperature down below 55C.

Re: Print sequentially?

Thanks you EldRick. I may have to try cura. In S3D, if I use a raft, the raft gets printed for each part before the part gets printed for any. Also, if I use more than one process per model, that first process gets printed for each model and then the second process gets printed for each model. So my...

Re: Bondtech BMG upgrade for the N series

I am also now using both extruders at once to print support structures for my ABS with HIPS. It's so easy and clean now. I could never get the Bowden thing working the way I wanted and I took off the stock extruders before I ever learned how to use two extruders successfully. So, until now, I was do...

Re: Bondtech BMG upgrade for the N series

Thank you firesped and JetGuy. Btw, I do not super insulate my hot end. In fact, I had no insulation on one of the ones that jammed. Lately my only insulation is to put a hole in a piece of insulation fiberglass and lay that on top of the hot end -- the sides and bottom are exposed. The idea being t...

Re: Bondtech BMG upgrade for the N series

I am totally with you on your thoughts. I knew you would have some wisdom in this area. I do like the idea of testing the laser cut Lexan windows. However, what do you think of a BBQ style rotating vent in the top of the enclosure? Maybe one in each corner to vent heat. I really like the idea of a f...

Re: Bondtech BMG upgrade for the N series

Fabulous work JetGuy and thank you. I am now running the BMG on my 2 N2's. I have run into a new problem since the upgrade: I have now developed a consistent problem of ABS melting in the cold end. Note that this happens on several hour prints with the printer cover on and doors closed. Vref is 0.5....

Re: Urgent fix needed

Yes Andy, and thanks. JetGuy brought this to my attention too. I started doing it manually with my "old" BondTecs, but the new dual direct drive seems to be a real bear to do a manual load even after releasing the motors. However, the new firmware allows the hot end to stay hot after a loa...

Re: Temperature does not rise

Yes, many things are changing over time with the N2. Like any complex set of systems, the first is not as good as the last IF the company providing the equipment continues to strive to make a better product. 3D printers are complex and many lessons need to be learned. Companies like MakerBot aren't ...

Re: Print sequentially?

So I decided to go ahead and try printing sequentially using S3D. Wow! What a revelation! I have had trouble getting some very small parts that I print a lot of to all stick. Usually one or two or even three of 20 get knocked loose and that messes up some others. With sequential printing, each part ...

The newest firmware - 9.2.1026 - now includes an option to not turn off the hot end. Thank you! This comes at a very opportune time as I now have the direct dual drive BondTech installed on both machines and I have found it nearly impossible to hand feed the filament past the drive gears even with t...
