    Managed to get into the office this week – tried linear advance test patterns

    Opted for 1.8mm but then produced a nice goal net! Tried changing values as the print progressed, but little changed.

    Will try lowering temp next time

    Please run a test pattern and copy and paste the entire repetier host log output from that print (be sure to clear the log before you start). Make sure you enable all log options.

    By the way, why are you using simplify3d for a test pattern? The test pattern gcode is generated with an online tool meaning you bypass simplify3d all together.

    Please either print the gcode directly from SDCard or from Repetier host (if you must use a pc/Mac)

    I was running the test pattern from the G-Code Library tab of the Machine Control Panel in Simplify3D – and then returned to test printing with a stringing test model from Thingiverse https://www.thingiverse.com/thing:2450004” class=”bbcode_url”>https://www.thingiverse.com/thing:2450004

    Higher numbers were tested as it was mentioned that those worked better for Bowden systems in an earlier post – but I guess for Repetier FW – will retest on wednesday when I’m back in the office

    Thanks again!

    So I managed to get some testing done last night.

    I tried the linear advance diagnostic print using a number of different range settings – from 50 up to 250. All looked bad.

    Went back to Simplify3D – played with the retraction / coast / speed settings – up to 7mm retraction – all still stringing. Have checked steps/mm – bang on with that – all vRefs are ok – motors not running hot.

    Not sure what to check next.

    HI Dan

    do we need to change the stepper driver to 8825 in the firmware as that’s what we’re using?

    I changed to the Marlin firmware a couple of days ago – seen oddities in the Z axis homing. When the Z axis is homed – the display shows it at 10mm.

    Also – the filament out sensor causes the print head to go to the back of the bed and perform a filament change procedure – unloading and then wanting to prime. I’ve disabled filament out in the FW for now – its probably just a FIL_RUNOUT_INVERTING change

    Hope to play more today

    I’ve had no luck with Linear Advance either – tried generative Gcode so test a whole range of values from 0 to 250 – but nothing seems to have any effect.Enabled advance in the firmware and changed the values to M233 Yxxx

    As an aside -we changed to the 2:1 hot end which has a different thermistor to the one we got with the original setup.

    Should the firmware be altered to reflect this? Is the one supplied the 100K NTC 3950??

    Testing the Linear Advance tonight

    It would explain a lot!!

    I’ll get a chance to try your manual method later today – what’s the current rating of the supplied Nema’s to set a baseline
