Re: Trying to print PLA with PVA support

I had to kill the print, because the PVA support stopped printing. I was able to fix the problem with the PVA extruder by doing an Unload and then a Load, so it was a temporary clog, not a "real" clog. This is similar to the problems I had with clear PLA. Can I expect PVA to have the same ...

Re: Trying to print PLA with PVA support

I adjusted the right extruder so that it was level with the left, and tried again. Things started out better, but as you can see, the outer ring (which is supposed to store the pre-extrusions) has collapsed into the print in two (opposing) places. I assume this is because the PVA is having trouble a...

Trying to print PLA with PVA support

When the printer arrived, the right nozzle was a bit higher than the left. This was fine for one-extruder printing, but now that I'm trying to extrude PVA with the right nozzle, there are the obvious problems (PVA not sticking to the bed). Are the nozzles supposed to be at the exact same height? I s...

Inefficient extruder motion in IdeaMaker

When I print this planetary gear, there are moments when the extruder moves briskly from left to right to left. It is as if it is going to locations that are sorted in Y but not by X. The optimal path would be a circular one. I'm not sure how important this is. Just wanted you to know.

Re: One extruder or dual-extruder?

I have been running a dual extruder N2+ for about a month, printing PLA, PC, and T-Glase, and only using the left extruder. I've never noticed a problem where the right/unused extruder bumped into anything. Perhaps I have been lucky so far. I had intended to use the dual extruders for PLA and solubl...

Re: Recover or restart after interruption?

It might be clearer if the choices were "continue with print" or "start a new print"

Re: PC mini clog after PLA

Thanks for taking the time to write so much! As it turns out, this was all my fault. There were two reels of clear filament, and I grabbed the wrong one. I was printing Taulman T-Glase using PolyCarbonate settings. Once I put the correct filament into the machine, it printed correctly, immediately. ...

PC mini clog after PLA

I have had problems printing clear Ultimachine PLA. I can get the print started, but eventually the extruder is printing into the air and the extruder motor is clicking. I spent another day on that, and have given up. I then switched to Taulman T-Glase and printed two objects without a problem at 24...

Re: Bondtech BMG upgrade for the N series

Thanks for your perspective. I had no idea there were two gears, one on each side. It was never mentioned on the BondTech page. I went back, and they mention DualDrive, but never explained what it was; it is not mentioned in the FAQ either. That does seem like a useful improvement. I guess one gear ...

Re: Bondtech BMG upgrade for the N series

For those of you who have switched to the BondTech, what are the real-world advantages? I understand the theoretical advantages of lower weight, and the real difference in resonating frequency, and the simpler mechanics for loading and unloading filament. But are there prints or materials that you c...

Clear PLA extrusion problems

While I can print perfectly with the colored PLA provided with the printer, I have problems with clear PLA from UltiMachine. I have read forums around the net, and it seems that I should try - reduced retraction - reduced temperatures - feeding filament faster - canola oil It is the last one I want ...

Feature Request: faster print termination

I started the wrong print, by accident. That print required that the build plate was at 100, which takes quite a while. I killed the print, but the printer insisted on getting up to 100 before it would quit. I finally just power-cycled the printer to save some time. It would be helpful if the printe...

Feature request: remembering window sizes/positions

Every time the main IdeaMaker window appears, it is the same size and in the same position; and it never is in the size and position that I chose previously. Same thing with the post-slicing Preview window. It would be nice of IdeaMaker remembered where the user last put these windows, and what size...

Slicing bugs

Parts of this STL are so thin that the slicer fails. Horizontal gaps appear on each side of the nostrils. I don't mind the slicer failing, but there should be error messages to warn the user that something has gone wrong http://www.jonbondy.com/sample.stl When this STL is sliced, pieces of filament ...

Re: bad slicing

You can download the STL from http://www.jonbondy.com/sample.stl; the slicing error should be obvious. The problem seems to occur because the model becomes very thin at one point. It would have been helpful if there were informative error messages when the slicing failed. Some other slicers fail, wh...
