XTLW ‘Ultimaker’ clonish 3D Printer

2018 April NZ$361.26 landed

http://www.ti.com/product/FDC1004/samplebuy


  • Uses that really light 2020 same as Anycubic Delta
  • Assembly:
    • X Y carriage feels tight
    • Cantilevered bed not stiff enough
    • Motors drive directly onto X / Y rods so hard to dissamble

Immediate changes

  • Relocate motors to be loop belt drive to X Y Rods:
    • Need to replicate 1 each of the 2 pillow blocks used for X & Y axis respectively
      • Bearings are 688Z (Plain – ID 8mm OD 16mm Width 5mm) of which I have… none!
      • X Pillow block: Center of shaft axis is 10mm in from the 2 outside edges so we need a bearing with a small enough radius to leave enough plastic to hold the bearing in places so a 608zz is too large at 22mm, I do have MF148ZZ which is OD 14mm so we will use that and order some 688z for later if needed
      • Pillow blocks are 15mm wide, mount holes are 6mm in from inside edge (is important to get pulleys to line up)
      • Fusion 360 did 1 of each corner pillow block, for MF148ZZ bearings
        • Printed on Wanhao Duplicator 4S in ABS / Makerbot Desktop 3.10 / Fine / Infill 50% / Shells 4
        • Had to up bearing bore from 14mm to 14.4mm to allow possible slight overextrusion on this printer
        • Did 4.1mm mount holes rather than the original parts 3mm
        • Had to file down a couple of corners slightly due to ABS warp  
      • Then redid in PETG on Anycubic Delta Linear Plus as hadn’t tried PETG before, seems good with slow print speed (50%)
      • Then added Y Microswitch to X Pillow Block, and altered X Pillow block to make room for a new X Microswitch & bracket

Cura 3.x Slicer

For Anycubic Delta Linear Plus installed 3.2

  • STL Model loaded up interface gets sluggish and really unusable
  • Notice that it automatically slices after every change so:
    • Preferences -> Configure Cura ->
      • General
        • Disabled Slice Automatically
      • Disabled all under privacy setting while I am here
      • Quality
        • Enabled Initial Layer Height
        • Enabled Infill Pattern
  • Layer view is unusable, so sluggish not responsive at all so:
    • Preferences -> Configure Cura ->
      • Viewport Behaviour:
        • Enabled Force layer view compatibility mode + restart

PLA Support settings to try:

https://www.instructables.com/id/Best-Support-Settings-for-3D-Printing/

Based on the previous results, I have decided to keep the following settings after few more tries:

  • Temperature: from 180C to 190C. Be careful, if the temperature is too low, the object will be more fragile because the layers will not stick well to each others.
  • Support interface ON
  • Interface thickness: 0.6mm
  • Distance from the support interface and the object: 0.2mm

D&D Miniatures AnyCubic Linear Plus

  • Draft Quality = 0.2mm layer height
  • Infill 50%
  • Printing Temperature 200 deg
  • Build plate 60 deg
  • Generate Support
    • Touching Build plate
    • Lines
    • Density 15
      • Support line distance (auto) = 2.667mm 
    • Support X distance 0.2mm
    • Enable support interface
      • Enable support roof Yes
      • Enable support floor Yes
    • Support interface thickness 0.6mm

20180507 Z Offset:

  • PLA 15.39
  • PETG 15.29 = good overall adhesion

 

20180417 Z Offset: 15.49mm


20180409 NZ$479.93

Box arrived in good shape.  Contents impressive & well packed


Construction notes:

  • Replaced the rectangular flat slot nuts with M4 Block nuts where possible
    • Estimate = 9 as did all 3 in each vertical to base joints
  • Extended cables for Z Endstop, and Auto levelling sensor, would’ve liked to extend Y Stepper cable slightly as well but is ok for now
  • A couple of cable clips on Extruder stepper cable
    • 2 x (5.4mm White Clip + M4 Hammer nut + M4 washer + M4 x 8mm Button head)
  • A couple of cable clips on cable from effector where goes into base
    • 2 x (10.?mm White Clip + M4 Hammer nut + M4 washer + M4 x 8mm Button head)
  • 6 feet underneath to improve airflow & sit better/quieter
    • 6 x (20mm rubber foot + M4 Hammer nut + M4 x 10mm button head)
  • Some cables are a bit short (*just* long enough) and some are way too long
  • Magnetic attachment for levelling probe ‘rocks’ as screw holding magnet into probe is not level with top of magnet:
    • Removed matching steel plate off effector and drilled out 6mm hollow in center to accomodate the top of the screw.
  • Instructions pretty good

To do:

  • External Mosfet for heat bed
  • Fan for steppers

Initial startup thoughts

  • Leveling process pretty straightforward
  • Loaded up Cura 3.2 and added this machine profile: https://www.thingiverse.com/thing:2367365
  • First print:
    • https://www.thingiverse.com/thing:1535703
    • Printed in supplied black PLA
    • 0.2 / 20% / Adhesion = No / Support = No
    • Cura estimated 7h actual = 8.5
    • Result was excellent
    • Stuck very hard to anycubic build surface

Golden ratio layer heights:

  • 0.0809
  • 0.1618
  • 0.3236

20180520 Initial assembly observations / modifications:

  • Used longer M5 bolts for attaching C Beam to Top / Bottom plates
  • Bottom belt idler assemblies:
    • Replaced non-toothed bottom belt idlers with toothed (GT2x6mm, 20T, B5mm)
    • Use M5 T-Block nuts (drilled the brackets out to 5mm)  rather than the supplied M4 swivel/drop in nuts (since I had to remove the top plate again to fix the twisted belt per below anyway)
  • Carriages:
    • One carriage had a twist in the belt
    • No more gaps silicone as a poor mans locktite on carriage set screws (for optical end stops) after setting to near enough to 5mm
  • X Motor mount:
    • Ground off corner of bracket to as bracket corner was interfering with the PSU case
    • Moved bracket slightly to alllow room between motor & PSU case
  • Added washers where seemed sensible e.g. motor brackets
  • Loaded up all 3 x 4 outside C-Beam 6mm slots with 3 M5 T-Block nuts each (3 x 4 x 3 = 36 nuts)

 

Wanhao Duplicator 4 Makerbot Desktop Windows 10 64Bit

Old PC retired, time to run up the duplicator 4 on new PC

Was running ReplicatorG on old machine.  We will see if we can use later software.

Installing Makerbot Desktop 3.10 (Beta)

Note to self re Firmware Upgrade option:

Wanhao is a clone of ‘Makerbot Replicator Dual’.  The Makerbot Desktop software will tell you your firmware is v7.2 and will allow an upgrade attempt to 7.5.

This forum Post suggests you *can* sucessfuly update to 7.5 if the machine type is set to Replicator Dual, but also says *DON’T DO IT* Yes all in caps.  So we won’t.

https://groups.google.com/forum/#!topic/wanhao-printer-3d/sjYp4XBoOvQ


Set as Replicator Dual, looking for good tradeoff between speed and quality, most parts are stressed so lookin for ABS with high % content for strenght

Replicator G:

  • 50% infill + 3 shells is good result

Makerbot Desktop

  • Low, Infill = 50%, 3 Shells is not too bad
  • Except: Smaller parts dimensionally slightly too large, will tweak Extruder settings:
    • Attempt 1: Settings -> Low -> Right Extruder: Change from 1.77 to 2.0mm = ABSOLUTLY NO CHANGE, same part printed at 1.77mm & 2.0mm is 7g
    • Attempt 1: Settings -> Low -> Right Extruder: Change from 1.77 to 2.25mm = ABSOLUTLY NO CHANGE, same part printed at 1.77mm & 2.25mm is 7g

 

ANET AM8 Notes

Assembly notes (both A8 & AM8)

  • Reverse cross brace on heat bed H frame as this flatterns the belt path
  • The extruder fan can is only fixed by the 2 M3x45 Cap Head Socket screws, so add 2 M3 screws through the fan guard and fan into the heatsink fins
  • The heat break needs to be firmly abutting the nozzle, so loosen the nozzle, and get the heat break in just far enough that the nozzle butts up against it and the block, takes a few goes to get it right

Wanhao Duplicator 4 revisited 20161228

Had a bracket to print.

Printer to be connected to W7Server running Win 10 Home 64 bit

Installed Python 2.x 64 bit version

Installed Replicator 4 (Drivers failed so possibly did a reinstall)

Open STL file and after aligning to print bed generated GCode then saved as x7G to SDCard

======

Ran through bed alignment process on printer multiple times, not a great result so bed must be bent.

Note I some time ago installed some Aluminium bed support arms to try to increase the stiffness.

Tried to insert SDCard but it wouldn’t click nicely in place, possibly some crud int eh SDCard socket?

Unscrewed button/SDCard board, so I could get to the SDCard, and used force to get it in/out a few times, still sticky.

Started teh print, it went well. After removing the completed print, started the same file again as I needed 2 of these.

ARRRRRRG. The bed had gone out of calibration and the nozzle tore up the Kapton tape.

=======

Replaced the Kapton tape..

So now leveling the bed after every print, printed 4 x 200mm long flat parts and now no issues

Have ordered some PEI sheet to try next
