  1. Thanks for all this expert feeback Gents. It has given me a great start. It's amazing how fast the brain can go from, "Wow this is great, what the hell do I do with it"......to....."Wow this is great, now I can fix the XXXXX around the house".......really amazing tool. I'm still playing with my test obect too. The largest one (10cm) being the most recent.........printing wise, does it look about right to you? There are some model edits I can do to certain areas to improve accuracy like under the number key pad near its "eye"........add some thickness to that bottom ledge........... How abou
  2. Super feedback gentlemen, thank you very much...... I will need to go over the numbers to understand them better but thanks, a great starting point...... Machine speeds, I think I am ok with......in fact maybe I should slow them down a bit? (See below).......Though the infill idea sounds interesting as the models I am making so far are just decorative...so they dont need to be bomb proof........Cura currently has infill settings of 20%......what could I get away with within reason for the objects below? The ticking noise, yep, it seemed to change if I wiggled the plastic as it headed in to
  3. Quiet as a Mouse........ Thanks again....... I do sometimes hear a quiet clicking noise that seems to be coming from the back of the machine (I can live with it), where the fillament gets fed in to the long tube........anything to worry about? The print it was doing at the time came out fine. Light click, every 8th of second-ish......last about 20-30 seconds.....went away...came back a bit....went away.........on this new print, a much bigger print, so far, no clicking from the back......... And UM2 machine speeds........lots of different ideas out there, but you guys seem to really know wh
  4. Many thanks gr5. All back together now, nice and tight......all axis move freely, and with simlar pressure needed to move each.....and NO SQUEEEK>!!!!!. Easy when you know how, and you, know how....thanks again. Will run off some prints now and see how things go. Will keep the thread posted.
  5. Sorry..was my old eyes.....there is a grub in there........DOH!...... Ok....will now stick it all back together and have another go..... Thanks all/Gr5........thought I am sure...I will be back.
  6. Decided to bumble through....always my favourted option. I have removed the large white vertical cover by taking out the single screw in the side wall.... I have removed the motor and its 4screw and black plastic wall mount...........and I am ready to move the pulley wheel along its shaft, closer to the motor...... But how do I move the pulley wheel along the shaft?....I see a hole in the side that looks like it would take a grub screw.....but I cant see anything in there to attach a tool too.........so am I doing this wrong or as the grub screw head sheered off somehow.....? Or have my ol
  7. Hi gr5 Thanks for the tip I will give it a try..... Is there a tutorial or dummies guide to taking one of these things apart in order to do this sort of thing?
  8. Hello all The shot below shows the belt coming out of the motor.........the belt at the top pulley seems all the way to the left.......the belt on the bottom pulley wheel seems all the way to the right........ I also took another video: If you pause at 30 Seconds you can see the two wheels (bottom one not so well) I have measured the inner edge of the belt, top and bottom.....with the internal left wall of the printer.........bottom inner edge of belt is 8.35mm from wall..........inner edge of belt top is 8.80mm from wall...............so if the measurements are correct.......when viewed
  9. Thank you both for your kind help. Must say I am loving this so far. Astonishing technology....... I was going to take some more footage and make some notes on a few more images, then both my cameras died. I will charge them up overnight, get another print going in the morning (like I need an excuse....would run all night now if it wouldnt keep us awake sqeeking at us...lol.)...... I will report back here in the morning. As I was sticking my nose in for a look and listen, I did get the feeling, hunch, it is something to do witth the motor belt..... Yes there is a wire rubbing against the
  10. Hi IRobert Yep everything looked fine in the box. Just had another play with the power off.....the "stickyness" of the axis seems pretty consistent no matter where the printer head is in the Y Axis.......if it was bent I might expect it to be free in some places but get tight in others....maybe.......? The measurements in the image seem ok to you? Drift of a couple 100ths of a mm does'nt seem too bad to me.
  11. Hello Again. Got a set of Mitutoyo digital verniers here, and this is as near as I can measure it......Have spent a decade on mills and lathes, this seems pretty parallel to me.........not perfect but "ok".......???
  12. Hi IRobertI Thanks for the quick reply. Have powered down and manually moved the print head.......the X Axis (Moving left to right as I stand in front of print)....moves freely......feels tight-ish....but it does move ok with moderate hand pressure...... Y Axis......stiff as hell........and when I manually move it, I can hear the squeek....and it SEEMS as if the squeek is coming from the upper back left of the machine, with the POV being again me in front of machine...........
  13. Hi All I'm not new to 3D, but I am new to 3D printing. Got a U2 yesterday, up and running in no time and it works a treat....... However.........after a few test prints....it has started to make an un-holy squeeking noise on one of the Axis. Took a video And I should add, that though I shove the camera at a few suspects. it is REALLY hard to work out exactly where the noise is coming from.......but it is LOUD......no printing overnight....and I cant be in the same room with it, unless Headphones are Full Blast.....lol. Help!. )
