  1. Hi all

    I've sucessfully modified and printed in two colours with a UM2 with two Olsson blocks.

    I've been experimenting with PVA soluble support with varying degrees of success.

    I've used Cura 15.xx with success but this does not allow for two printing independent speeds ie model and support. I've also tried various options/printers in Cura 2.6x without success. When selecting Ultimaker 2 Dual there is no provision for separate speed for extruder #2 (PVA) but the support is printed from extruder #1. I've reconfigured the settings for UM3 to the ones for UM2, added the second extruder and this gives  me the option of different speeds for the model material and the soluble support but it doesn't perform as it should.

    So the question is where am I going wrong?

    What am I missing in either or both versions of Cura?

    All help welcome.

    Thanks

  2. Hi all

    I've added a second extruder to my Ultimaker2 and all works as it should.

    My question is I've modified a file that has a nozzle size indicator that clips on the from of the printer, however the numbers it are a bit difficult to read at first glance.

    So I drew in Solidworks a dial with 'cut' numbers and another file with the extruded numbers in the exact same place as the number 'cuts' on the dial.

    The issue is when both are brought into Cura in the correct orientation the extruded numbers are placed above the dial indicator not recessed as desired, could someone guide me as to how to merge the two files so that the extruded numbers sit flush in the 'cuts' made for them. Please see the images below.

  3. I realise from reading this forum and other sources there will be issues.

    As far as firmware goes i've come across  Ginge's Marlin Builder that includes the option of the second extruder but it also asks about the heated bed temperature sensor, I don't have the spec for this, where can I find it?

    Thanks

  4. Hi all

    I've upgraded a UM2 with two Olson Block hot ends and updated the firmware from Cura 2.1.x. However I cannot find any way of loading the 2nd material. How do I tell it to do this?

    Any tips or pointers to resources for printing with two colours would be very welcome.

    Thanks in advance

  5. Hi Folks

    Back again after the holidays.

    Thanks TInkergnome for the firmware upgrade for the PID Autotune. Worked and stored a treat.

    However I'm getting the dreaded 'Heater Error - Contact Ultimaker' now!

    In an earlier post it was suggested setting the maximum temperature.

    Could that be my problem? There doesn't seem to a Gcode for setting this.

    The printer uses a new PT100 sensor and the E3Dv6 and printing with ColorFabb PLA.

    Regards

  6. Following on from the suggestions.

    Whenever I send a command such as m301 px ix dx or M500 there is no message received back from the printer.

    I would have thought there should have been.

    I can only connect at a baud rate of 250000 everything else reports something like this

    Connecting...

    Attempted to write invalid text to console, which could be due to an invalid baudrate

  7. For your imformation here is the list of commands I've used from pronterface.

    Please note after M500 the printer was switched off and back on.

  8. I've redone the AutoTune with Pronterface and the results are the same, ie when I reconnect after a power cycle the PIDs report the same as before I changed them.

    There MUST be something else !

    A jumper needing set to permit m500?

    I don't know how where to get the hex code from for recompiling or even how to recompile, it's an area I'd rather not get invovled in.

    I'm using the latest version of Tinkergnome firmware as linked to above.

  9. Using Pronterface I've run the PID autotune and entered the last set of P I D values (P44.33, I8.4 and D58.45) using M301 followed by M500 to store them.

    Other vaules shown earlier in the Autotune were P16.16, I1.36, D47.85 followed by P26.48, I1.39, and D125.84. Is it usual for the three sets of values to be displayed?

    I then switched the printer off and on again and sent M503 to verify the PID values. These returned as P10, I12.50 and D100.00

    Is this normal as they are exactly the same figures as stated before I sent the M303 command?

    Just to remind you I have an Ultimaker2.

    Regards

  10. Hi all

    I know this has probably been covered else where, if so please direct me to it.

    I have upgraded my UM2 to use the E3D v6 hotend using a mount I located from YouImangine and printed in ABSplus on a Dimension printer.

    My problem is exactly what and how to I upgrade the firmware to take into account any issue raised with the upgrade eg maximun X height or other axis change, maximum temperature of the hotend etc.

    I am not a programmer so am asking the experts for precise instructions.

    Your help is greatly welcome.

  11. Yes I did read the hours direct from the printer they cover between 210 and 340 hours which is not a long time.

    There are no modifications to the printer in any way.

    The four main screws holding the print head together are only slightly hand tight if that makes sense.

    As in the main picture above the PLA bulges and retracts slghtly into the bowden tube and seems a little tight when I move the material forward. Is this normal?

    I can disassemble the print head as far as removing the spring from the teflon part but is there a way of getting the teflon bit out from the nozzle assembly?
