  24       <div class="date">12th March 2009</div>
  25       <div class="body"><p>Lenge siden det var en oppdatering av status for min 3D-skriver og
  26 i mellomtiden har det skjedd en god del.  Reprap-en er nesten ferdig
  27 montert, og elektronikken er også nesten ferdig loddet.  Det ser ut
  28 til at bits-from-bytes sitt byggesett versjon 2.01 hadde noen småfeil,
  29 der en del manglet og en annen hadde suboptimalt design.  Jeg løser
  30 antagelig det ene problemet med å borre noen ekstra hull til skruver i
  31 en plastdelen som trenger å festes.  Det andre problemet håper jeg å
  32 få hjelp fra Audun Vaaler ved Høgskolen i Østfold til å løse.
  33 Høgskolen er igang med å bygge en tilsvarende reprap i versjon 2.0, og
  34 er kommet litt lenger enn meg.  De kan forhåpentligvis skrive ut den
  35 delen jeg mangler på denne.</p>
  36
  37 <p>Når det gjelder elektronikken, så er mye allerede loddet sammen av
  38 min venn Anders Rosnes, som har mer peiling på elektronikk og lodding
  39 enn meg.  Jeg fikk i dag testet
  40 <a href="http://reprap.org/bin/view/Main/Stepper_Motor_Driver_1_1">stepper
  41 motordriveren (v1.1)</a>, og det fungerte.  Jeg møtte et lite problem
  42 med strømforsyningen, en standard ATX-strømforsyning som nektet å
  43 fungere før jeg hadde satt en ledning mellom GRD og PS_ON som
  44 beskrevet på
  45 <a href="http://dev.www.reprap.org/bin/view/Main/PCPowerSupply">reprap-sidene
  46 om PC-strømforsyninger</a>.  Jeg møtte også et annet problem med
  47 Arduino-programvaren.  Versjon 0013 fungerer visst ikke på
  48 Debian/Etch.  Den kompilerte binæren ble på 0 bytes.  En side jeg fant
  49 vha. et Google-søk
  50 <a href="http://www.arduino.cc/cgi-bin/yabb2/YaBB.pl?num=1234153046/5">tipset
  51 meg</A> om at en nedgradering
  52 til <a href="http://arduino.googlecode.com/files/arduino-0012-linux.tgz">versjon
  53 0012</a> kunne løse problemet, og endelig ser jeg motorakslingen
  54 snurre.  Nå er det å koble sammen mekanikk og elektronikk for å se om
  55 reprap-en kvikner til.</p>
