    • RE: Cartesian Geometry Question (Solved)

      I think I might have finally resolved this. ☺

      Having a careful think about SupraGuy's comments, I resolved to head back to square one and test everything. First up, I swapped the Y stepper with a known serviceable item. I then went back through the Dozuki set up guide and checked that the end stops were all working.

      I then disconnected the belt drive on the bed to see if the stepper would move as it should and if so in what direction.

      Bingo the Y stepper was doing exactly what it should. I then reconnected the bed with a lot less tension on the belt and Home Y worked again.

      Thanks to all for your help.

      I have now done the changes to resolve the mirror image problem and again everything appears to be working in the correct sense.
      I will now try a print of the offending item that started all this and let you know if everything is still happy happy joy joy.

    • RE: Aus 3D IR probe set up problems

      Having had a good read of the RepRap Dozuki, I believe I have answered all of my questions and amended the Bed.G file to make things work.
      The probe is now working correctly and the machine is now working on its first test print.

      DOH!!!!!!!!!!!!!!!!

      Often it is the obvious mistake that will only get picked up by another set of eyes.

      Thank you Phaedrux it is all working as advertised again.

    • RE: G1 Issues

      @fcwilt . Than you Frederick I have finally got an explanation of what H2 does in the G90 command. I have been searching for this for ages and your explanations of H1 and H2 above finally made sense of everything. I was also having some fun getting my head around where and when if should be using G90 vs G91.

      I have now rebuilt my Home all file and everything now works exactly as it should. No need for M594 any more.

      The working Home all looks like this:

      M400 ; make sure everything has stopped before we make changes

      M915 X Y S2 R0 F0 ; set X and Y to sensitivity 2, do nothing when stall, unfiltered
      M574 X1 Y1 S3 ; set end stops to use motor stall
      G91 ; use relative positioning
      G1 H2 Z5 F1200 ; Lower bed 5mm

      G1 H1 X-325 F3600 ; Move X to Home
      G1 H1 Y-325 F3600 ; move Y to home

      G90 ; Use Absolute positioning
      G1 X150 Y150 F4000 ; Move head to center of bed
      G30 ; Lower Head, Stop when probe triggered and set Z to trigger height

      G1 X0 Y0 F4000 ; Return Head to Home

      @fcwilt Hi Frederick. Yes I did cut the relevant parts into X Y and Z homing files. Your input has also significantly reduced the number of lines in each. Thanks again for all your help.

      Cheers

    • VSSA Thermistor 2 fault

      I have been modifying a printer with a Duet 2 board. On boot up the Bed Heater connected to E1 is showing a temp of -271 degrees.
      The E0 hot end heater is showing the correct ambient temp.

      If I swap the two thermistor plugs Bed Heat reads ambient on E0 and Hot end faults to -271 on E1.
      This suggests that there is a board fault with E1 despite the fact that a close visual inspection doesn't show any physical damage
      I presume that I can connect the bed thermistor to any one of the 5 spare thermistor pins 35 - 39 on the expansion socket. As there is only one pin for each of those five spare spots, I presume the other thermistor lead is connected to ground?

    • Duet 2 & Voron 2.4

      I have an existing Core XY using a Duet 2 Wifi that I plan to convert to a Voron 2.4. This of course will require 4 x Z steppers.
      I assume that the addition of a Duet expansion board should allow this to happen.

      I have tried searching for similar posts on this issue but most seem specific to the Duet 3.

      Is this concept doable? and has anyone been there done that?

      Cheers

    • RE: High Power Led

      @phaedrux I do not have data sheets for either fan. The other options are to connect it to the Panel Due 5v and GND. Other option is to wire a buck converter to the 12v PSU direct.

    • High Power Led

      Hi
      I am planning to use a 3 Watt high power LED (700milliamps at 5vDC) to light my print surface.

      I just want to double check that it can be powered from a spare Fan connector without problems.

    • RE: RRF3 GPIO Confusion

      Hi Phaedrux
      Answers to your questions:

      1. The white wire runs alongside the Hot end fans, thermistor and heater but none of these are active with this current round of testing.
      2. The BL Touch was working 100% correctly before the LED changes.
      3. For the LEDs I plugged signal leads for R G & B into Heater pins 4, 5 and 6 on the expansion board. These can be seen in the Photo. The LEDs have their own direct feed from the PSU and are linked through a Darlington Array (ULN2803) chip.

      I have also sent the following commands with results as shown:

      Power On - BLT cycles and LED goes orange.
      M199 - Z Probe at min stop
      G92 Z50 DWC shows Z at 50
      M119 - Z Probe at min stop
      M280 P0 S10 Probe extends blue led illuminates
      M119 - z Probe at min stop

      BLT.jpg
      M280 P0 S90 - probe retracts red led illuminates
      M119 - z probe at min stop
