I'm curious if I'm the only one that has a bump in the middle of his build plate from the set screw (?) used to screw it down. It's like "Gee, thanks for putting this .1 mm bump in the middle of my build platform."

+Michael Forte​, that's what I meant by the first option. The mat adds a small amount of mass but also add insulation to the bottom. Fortunately it's a Nema 23 ... I think it should be able to handle it.

It looks like most of my problems in my earlier post are crap filament. This is pla on the same printer with extrusion flow set to 110%.

On something big and flat like that it has more of a tenancy to curl. I try to keep my bed hot.

So here's one that drives me crazy. The nuts on the four leveling screws on my rigidbot will not stay on. Without fail, if I do a few prints, I'll hear one (often a different one) fall right off. It isn't like we can use locktite on these since we need to adjust them to level the platform (leveling my platform is another rant I could go on about with the rigidbot).

Does anyone else run into this constantly? I've had probably five 3D printers and worked with a few more in my hackerspace and I've never had the nuts on the leveling screws continuously work themselves off like this.

Replace the normal m3 nuts with some m3 nyloc nuts...no more losing your nuts again :-)

I'm getting a lot of seemingly clogged nozzle issues with my original IAP extruder and hotend. I'm considering switching to one of the E3D hotends. Looking at them (online), I'm not sure what modifications need to be made, if any, in order to mount an E3D hotend in my bot. Since a number of you have done it, does anyone have any pointers (and maybe details pics) for mounting and which E3D hotend to use?

Let me know when you want my money, Peter. I filled out your Google doc and I ordered two v6 hoteneds on filastruder last night. I added the Byebye board on the Google doc as I assumed I would need it.

+John Harper, a question that comes up in Lady Blackbird: As you conceive of it, is gravity in the wild blue yonder down towards the sun or down towards the local planetoid's center of mass? One would assume the latter but that means that small masses (like Magister Lor's home and ships) are zero g environments, which is not stated in anything I've seen. We've actually debated this more than once in my gaming group while playing.

+John Harper, maybe you could just say that Nightport has a side constantly in the shadow and it is there the outlaws built their city.

OMG. I need a firmware hack to turn off the seizure inducing blinking red lights when I'm printing. They drive me crazy in the dark.

Do people have preferred brands of PLA from the stock available through Amazon?

I'm having a hell of a time with layer adhesion using the PET+ that I've been successfully using before.

I suspect it is a leveling / z height issue but I wanted to ask what others think. I've had several prints like the following that I had to abort.

PETG is my filament of choice. I have had no real issue with it at all except when I had my old RB extruder...

I think I found my extruder problem.

I had another tube (actually, another extruder from Inventapart).

I'm waiting for the parts to do the dual E3D mount.

Question for folks. I have a 10x10x10 Rigidbot with a single extruder. It is actually working very well and reliably for me. I'm wanting to move to dual extrusion. I was wondering if the folks who have the dual extruder version have any thoughts on it. I'm not sure if I want to pay $150 for dual extruder parts from Inventapart or try to source something from my own.

Has anyone here had especially positive or negative experiences with the dual extruder from Inventapart? Has anyone built their own dual extruder?

I have setup dual e3d extruders. Like Gary said, it takes a lot of tweeking and a very flat build plate to ensure the heads are level. I still find myself printing with a single head 99% of the time. It probaly took me a couple of weeks to experiment and get the heads and build plate level. Just be prepared to spend some time modding the bot and you will have fun, if you expect to just install the extra head and go, you will be in for a rude shock...lol.

It's great fun if you love experimenting and tweeking, but can be frustrating if you just want to knock out single color prints fast.
