  1. Sorry for the gravedigging, but I just wanted to share that nail polish remover improves adhesion too. Yesterday I printed a 80x160x2 mm rectangular piece and I didn't have any IPA. So, being too impatient to go out and buy it, I used my gf's nail polish remover and the piece stuck to the tape, and the tape to the bed, so tightly I had immense trouble getting it off! I was simply amazed by how strongly it was attached. I only succeeded in getting it off by removing the whole bed from the printer and then persistently driving a utility knife between the bed and the tape, and after that I still had to remove the tape from the plastic by using lots more nail polish remover.
  2. Hello again, excuse my double post, but: I thought "what the hell, let's add extrusion/retraction", so I did. You can download this new version here. As before, just extract the archive in the pronterfanUI folder, overwriting everything. This version supports fan control, temperature control, hotbed/extruder on/off and extrusion/retraction control for the first extruder. If anyone feels like adding the same functionality for the second extruder, feel free (I don't have one myself). I'll keep the old version in my earlier post, in case there are any bugs with the new version. I think what is needed after this version is a bit of redesign, so it looks a bit less cluttered and has a uniform style.
  3. Oops, forgot to put in Citystars' code... too many script.py files running around on my hard drive I updated the archive; download link is: https://app.box.com/s/75skiqucz6az8ldine4a Now it should work... I don't have a heatbed or a second extruder, so I can't test everything though.
  4. Hi, I noticed today that when copy-pasting Wayne's code, the indentation of the lines seem to be lost, which screws up the python code. When I corrected that, it works just fine. However, I found it a bit impractical that the console and the temperature panel were in the same space (as sometimes console messages would print over the temperature buttons), so I did some small modifications to the design to make some room. I uploaded the result, to be found https://app.box.com/s/75skiqucz6az8ldine4a. Just put the files in the PronterfanUI folder, overwriting everything. This version contains fan control (by owen), temperature control (by Wayne), and on/off buttons for the heatbed and extruder (by Citystars). I hope this will be useful to some people.
  5. Hello all, Thanks for your replies! I tried extruding using the Jog fuction in Cura, but that didn't help too much I think. The skirt function is on, I think, because before starting to print, it prints a line around the model. Maybe I should make it print more of those. I mean: I don't really mind wasting so little material if that makes the blobbing go away...One thing though: in my version of Cura I have both Skirt and Brim. Which one should I use, and what's the difference between the two? and @drayson: I haven't changed the default code at all. So it's just the same code as when I opened up Cura for the first time: ;Sliced at: {day} {date} {time} ;Basic settings: Layer height: {layer_height} Walls: {wall_thickness} Fill: {fill_density} ;Print time: {print_time} ;Filament used: {filament_amount}m {filament_weight}g ;Filament cost: {filament_cost} G21 ;metric values G90 ;absolute positioning M107 ;start with the fan off G28 X0 Y0 ;move X/Y to min endstops G28 Z0 ;move Z to min endstops G1 Z15.0 F{travel_speed} ;move the platform down 15mm G92 E0 ;zero the extruded length G1 F200 E3 ;extrude 3mm of feed stock G92 E0 ;zero the extruded length again G1 F{travel_speed} M117 Printing... I could indeed tell it to extrude more than the 3mm it already seems to extrude in the beginning. Thanks for all your tips! I'll start experimenting a bit and report back if I get good results!
  6. Hello all, I received the Ultimaker as a gift. Assembled it without problems - the wiki documentation was extremely clear, thanks! The printer printed excellently already without any calibration (and without me knowing anything about calibration too...). I just opened Cura, did the wizard, after which it sent me to that Ultimaker robot model and I just hit "print", that's it. There's only one problem, not a very serious one, but still: it seems that before (when heating up) and after printing (when the head is still hot), filament comes out of the head without the extruder moving. As a consequence, often my prints have random filament blobs, consisting of filament that came out of the head while it was heating up, attached to them. Moreover, it seems that because of this filament loss during the heating and cooling phase, there's too little pressure when the actual print starts, such that the first line it tries to print is often very thin or nonexistant. Again, it's not a serious issue; it seems to usually solve itself during the print, and any random filament sticking out I can easily remove afterwards, but I'd still like to solve it if possible. Any advice?
