    Buying Used Ultimaker2

    Hello! If you're still looking for a used UM2 printer, I've just posted selling mine. If you're interested, you can check the details here: https://ultimaker.com/en/community/21027-selling-lightly-used-ultimaker-2-with-mods
  2. Buenos dias! Debido a la falta de tiempo para dedicarle a la impresión 3D, estoy vendiendo mi ultimaker 2 Está en perfectas condiciones, la he modificado para usar el alimentador de IrobertI y un bloque olsson, pero también tengo las piezas originales. La impresora viene con varias boquillas para el bloque olson: 2x0,4mm de latón, 1x0,25mm de latón, 1x0,8mm de latón, 1x0,4mm de acero y 1x0,8mm de acero. La impresora siempre ha estado en un sitio seco, y cuando no ha estado en uso, siempre ha estado cubierta para prevenir el polvo. El sensor pt100 y el cartucho de calor fueron cambiados recientemente y tienen menos de 300 horas de impresión. La cama de vidrio tiene algunos rasguños en una de las caras, debido a una impresión difícil de separar, pero la otra cara está en perfecto estado. Incluyo también material de impresión, que incluye varios metros de pla de diferentes colores, XT transparente de colorfabb y bronce, también de colorfabb. Estoy dispuesto a venderla por 1400€ sin iva, con envío incluido. También se puede negociar el precio, pero si es menor al anterior, el envío corre por cuenta del comprador. Cualquier duda o pregunta, estoy disponible, y puedo grabar videos de la impresora en acción si hace falta. [EDIT]Precio corregido[/EDIT]
  3. Hello and good morning! Due to time constraints - as in, I've no longer have enough spare time to model & print - I'm selling my ultimaker 2. It's in working condition, with roughly 1000+ of printing time. I've modified it with IrobertI's feeder and the olsson block, but I still have both the old block & nozzle, and the original feeder parts. The printer comes with 2x04.mm brass nozzles, 1x0.8mm brass nozzle, 1x0.25mm brass nozzle, 1x0.4mm steel nozzle and 1x0.8mm steel nozzle and it has always been kept in a dry storing place, covered when not in use. The pt100 sensor is relatively new (less than 300 hours of printing, aprox) and the heat block as well. The glass bed has some visible scratches on one side - caused when trying to pull a cold printed piece, but it's in working condition on the other side. I'm willing to sell it for 1.400€, no VAT and I can send it to any place in europe for that price. I'm willing to negotiate the price, too, but if it's lower than that, delivery fees will be paid by the buyer. If you have any questions, or want to see a video of the printer in action, let me know. [EDIT]Forgot to add, the printer comes with printing filaments: several meters of PLA of assorted colors, XT transparent & bronce form colorfabb.[/EDIT] [EDIT]Fixed price typo[/EDIT]
  4. True. That's why I thought weird when cura showed me the layer view and I noticed the crosshatch pattern. At first I thought the infill density might have something to do with it, thinking that perhaps cura might have overridden it for some reason. So I just changed it to 100% to see if that was the issue, but it wasn't. I'm still fiddling with the "faulty" settings, but I can't seem to find which one is causing this. After resetting the profile settings, it works normally, but I'm curious as to what might be going on here.
  5. Sorry, I was fiddling with the settings to see if something changed, and I think I posted a different profile file. I did as you suggested and reset the setting to default. Indeed, it looks completely solid again (as it should) at 100% fill density, but also at 0% fill density. The parts are 1.275mm in height. However, if I load the posted profile, the holes in the top layer appear again, even if I set it to 100% fill density. I wonder what could be the cause of this?
  6. Lately I've been struggling with some underextruding issues, which make the top layer of my prints a rather ugly mess. Today, when sending a test print to cura, I noticed something strange on the top layers: This is the top layer, and you can clearly see the holes between the lines. This results in a rough surface when the print is finished. The weird part is that in the lower layers, the effect is less pronounced: Until it disappears completely at layer 1: I've tried fiddling with some of the setting from cura, but I can't get the top layer to be as smooth as the first layer. I admit I've no idea what might be causing this. Have you run into this issue before? could it be a bug with cura, or is it something I'm not doing right? Thanks in advance. Here's the profile settings I'm using: [profile] layer_height = 0.1 wall_thickness = 0.4 retraction_enable = True solid_layer_thickness = 1.2 fill_density = 100 nozzle_size = 0.4 print_speed = 60 print_temperature = 210 print_temperature2 = 0 print_temperature3 = 0 print_temperature4 = 0 print_temperature5 = 0 print_bed_temperature = 70 support = None platform_adhesion = None support_dual_extrusion = Both wipe_tower = False wipe_tower_volume = 15 ooze_shield = False filament_diameter = 2.85 filament_diameter2 = 0 filament_diameter3 = 0 filament_diameter4 = 0 filament_diameter5 = 0 filament_flow = 100.0 retraction_speed = 40.0 retraction_amount = 4.5 retraction_dual_amount = 16.5 retraction_min_travel = 0.5 retraction_combing = Off retraction_minimal_extrusion = 0.02 retraction_hop = 0.2 bottom_thickness = 0.3 layer0_width_factor = 100 object_sink = 0.0 overlap_dual = 0.15 travel_speed = 150.0 bottom_layer_speed = 20 infill_speed = 0.0 solidarea_speed = 0.0 inset0_speed = 0.0 insetx_speed = 0.0 cool_min_layer_time = 5 fan_enabled = True skirt_line_count = 3 skirt_gap = 3.0 skirt_minimal_length = 150.0 fan_full_height = 2 fan_speed = 100 fan_speed_max = 100 cool_min_feedrate = 20 cool_head_lift = False solid_top = True solid_bottom = True fill_overlap = 15 support_type = Lines support_angle = 60 support_fill_rate = 15 support_xy_distance = 0.7 support_z_distance = 0.15 spiralize = False simple_mode = False brim_line_count = 20 raft_margin = 5.0 raft_line_spacing = 3.0 raft_base_thickness = 0.3 raft_base_linewidth = 1.0 raft_interface_thickness = 0.27 raft_interface_linewidth = 0.4 raft_airgap_all = 0.0 raft_airgap = 0.22 raft_surface_layers = 2 raft_surface_thickness = 0.27 raft_surface_linewidth = 0.4 fix_horrible_union_all_type_a = True fix_horrible_union_all_type_b = False fix_horrible_use_open_bits = False fix_horrible_extensive_stitching = False plugin_config = object_center_x = -1 object_center_y = -1

    I'm having trouble with this print, what am I doing wrong?

    Makes sense. I'll try with stick glue first, and if that doesn't work, I'll see if I can find M3 tape.

    I'm having trouble with this print, what am I doing wrong?

    Wow, thanks a lot for the advice! Yes, I'm using PLA. I thought the bevel at 45 degrees would be good enough to print without support, but I completely forgot about the temperature I tried now. I don't have blue tape, so what I did was leave the heated bed on for the first layer (I added a brim to both prints) then turn it of as soon as the base was done. With that and Labern's advice, it printed perfectly. I'll be sure to write this in my printing notes, I can see how it would be very useful for other printing projects. Thank you very much!
  9. Good night! I'm currently trying what I thought it would be a simple print, a round "staple" with a loop on top. The first part prints very well, but when the nozzle reaches the flat top, the nozzle begins pushing the top down, as if it were trying to print lower than the current height. The loop in the flat top also prints with the nozzle touching the printed material (and pushing it to the borders with the movement). The results, as you can see, are not pretty: What am I doing wrong with this print? Is it a problem of printer bed calibration or something else? Thanks for your advice! P.D.: I'm using these settings: [profile] layer_height = 0.06 wall_thickness = 0.8 retraction_enable = True solid_layer_thickness = 0.8 fill_density = 100 nozzle_size = 0.4 print_speed = 60

    PLA not coming out of the nozzle

    Thanks for the graph, gr5, I've bookmarked it to keep in handy for future references :cool: It's indeed good advice, I'm currently printing the replacement, it'll finish in 2 hours. I'm currently using 0.1mm layer height for most projects. I have a batch of minis waiting to be printed, which I plan to print at 0.05 for high quality and see how it works out.

    PLA not coming out of the nozzle

    I'm currently printing at 50 mm/s, with a temperature of 210º. The printer is working again. I withdrew all the material and tightened the tension screw until the indicator was in the middle. I'm currently printing the leveling circles, but as soon as that works, I'll print the new feeder system as per your suggestion. Thanks!

    PLA not coming out of the nozzle

    Kris: yes, I've cleaned the nozzle using the atomic method. I'm not sure what other methods I can use to clean the nozzle. Acetone, maybe?
  13. Good day. I'm having a strange problem with my ultimaker 2 printer. Yesterday, after replacing a broken heat sensor, I started printing to see if everything was ok. First print came out beautifully, no problems at all. Then I left the printer doing an overnight job, only to find out this morning that the printer stopped shortly after finishing the rafts. I retracted the material to see if the nozzle was clogged, but it appears to be ok - I can insert an acupunture needle without problems. However, I had to cut part of the PLA filament, as it looked like this: The tension indicator is somewhere near a third of the box: The coils of the filament are loose, and if I heat up the nozzle I can make it extrude by pushing the filament manually. However, as soon as I send something to print, the head moves but no material comes out. The third fan is working correctly. I've tried tightening the tension screw, as well as loosening it, but the problem is still there, and I'm at a loss as to what else I can try. Any suggestions? Thanks in advance

    Error - Stopped Temp sensor

    Thanks, 3Poro. I'll bookmark it and read it carefully. I've already ordered a replacement sensor - as I can't afford to wait an additional 3-4 days until the support ticket is answered. I hope this won't become a recurrent problem.

    Error - Stopped Temp sensor

    Thanks for your advice, Gr5. I've already opened a ticket and I've updated them this morning with my previous post. I'll guess I'll just have to wait until they answer back. Thanks again for your advice
