Thoughts about Raise3D, 3D printing and making in general.
I'm trying to print the circuit duct work using PLA and Poly Suport for the raft and support sturcture. I set the PLA temp at 215 and the Poly Support at 230 with everything else standard. The bed temp was 45. As you can see, the poly support didn't adhere very well and caused the failed prints. I tried twice, once with Poly at 225 and then 230. Anybody know what to try next?
I have recently installed new V2 hot end. Just starting with using new V2. PolySupport sheet says 225-235, but i'll try Julia's settings. By the way, where are the original downloads for the Raise 3D circuit board covers? I have them downloaded, but can't find the post where I downloaded them. I was looking for more information on printing the covers.
Oh, also, Polysupport is really soft, slippery, and stretchy, and so may slip in the stock Raise feeder. Have a close look at what's happening if you continue to have failures to see if feeder slippage is the issue. Various mods to fix slippage have been discussed elsewhere here.
Yes, I've had slippage and installed your O-ring fix. That seems to be working well. Haven't had slippage on the right extruder. I have had some slippage on the left extruder and plan to put another O-ring on the left side.
Well, the print failed after 23 hrs. A lot of support stringing and the left black PLA stripped and wasn't feeding. The PolySupport wasn't feeding either when I ended it. I also found it very difficult to remove the support in this intricate piece for electronics cover. I have wipewall and retraction set. How do I print this? Do I need water soluble support material? Has someone else printed the Raise electronics covers? And, I still haven't been able to find the original posting with links to the original covers.
I'm still trying to print the electronics covers. The bottom piece printed very nicely (pic#2). When printing the top piece, the X-axis shifted all 3 tries. once to the right and twice to the left (pic#3). And twice the cover fell over while printing. So, although it looks like it stuck to the buildtak ( I wipe it down with alcohol before each print) at some point it came unstuck and fell over ruining the print. Even though it lost it's x setting, I thought I would let it finish and then cut it and glue it in the correct position. But it fell over. So, why the shift in the x axis? And how do I make it stick a little better to the buildtak? I am running bed temp at 40, nozzle temp 215. I'm using PolyMax PLA.
Interesting. I have my pla at 215, polysupport at 240, and bed sitting at 40. Your nozzle temps is fine. Like John said your adhesion to the bed for some reason isnt good. Ive also ranged from 40-60 on bed temp to get good sticks (with raise3d filaments).....that filament might just want 60 bed temp.
This is a controversial topic, but personally I like to smear glue stick on the Buildtak. Maybe this "defeats" the way Buildtak is supposed to work, but it works for me, and maybe it's also why I don't experience the problem of parts being "too stuck" that's been reported by others. I scribble the glue stick all around the area where the print is going to be, then I smear it into a thin film with a damp paper towel. For prints with little bottom surface area, or mostly support in contact with the bed, using a raft can help a lot with adhesion too.

does that also aid with removing too tightly adhered prints?
Thanks, the bed temp at 60 made it stick real good, but was able to remove without an issue. The electronics cover printed fine, except for a little jog at the top of the round fan housing. It joged over for a few layers, then returned to the original x-axis spot. I thought this was strange. It is not supposed to know where the x-axis is supposed to be. The inside of the round section is very rough and stringy. I can clean it up but it's not neat. I upped the temp to 220 which could have caused the rough inner printing.
