    Hello all!

    I have a unique situation and I’m having some issues.

    I upgraded my Dreamer with a Titan extruder and e3d v6 hotend.

    In guild to get this to piece of work I upped the extrusion multiplier to 3.fourscore and it prints great… sometimes.

    Later on awhile through a impress it starts chewing through the filament until it wears it in two.

    Whatsoever thought what is causing this. Up until it does that it works corking!

    I have tried increasing and decreasing tension on the filament just to run into what would happen and information technology still does information technology either manner. I’m a bit at a loss here every bit this is my first fourth dimension doing something similar this or messing with the Titan extruder.

    Thanks for the reply!

    It isn’t really out of calibration. The titan extruder has a gear ratio that comes in to play. So you have to either adjust e steps or up the multiplier to compensate for this.

    I can’t alter e steps on the Dreamer to my knowledge though.

    Uhh, that is exactly what calibrating the extruder does you know
    :)

    Possibly sentinel Toms excellent video:

    @JustinDS89
    Is there no way to modify the firmware on the FlashForge? My guess is that information technology would take been better to recalibrate the extruder and reflash the firmware? or at the very least using Thou-Code to ready the eastward-steps. If it follows the pseudo Chiliad-Code standard
    M92 Ennn
    would do it.

    Ah okay haha, thought you meant something else.

    To my knowledge no there isn’t, merely I hope I’thou wrong lol.

    I may effort a postal service processing gcode script if i can figure out how to practice that.

    Some folks install Sailfish on the FF (which would then be updateable/editiable) but I don’t take 1 to play with so have that with a grain of salt.

    From my understanding you lot can simply do that on the Creator Pro, just not certain.

    Haven’t found a manner to adjust the steps without a complete board upgrade.

    It wasn’t only that model as information technology ate through the filament on another model.

    I don’t understand why it prints bully and and so starts chewing through the filament.

    I but disassembled everything and put it back together. I adjusted the retraction to 0.5mm and 15 mm/s. This seems quite low, but I don’t know what else to do.

    EDIT: Tested it out and it started grinding the filament by the second layer…

    Did you try what
    @WheresWaldo
    posted? You can fix the extrusion Steps in EEPROM assuming its non disabled on the FF machines (I wouldn’t think so). I take a titan on a few machines and I did find if you tighten the bolts that hold the cover on to much it will demark up the filament drive and cause a similar upshot. might want to recheck assembly, as well attempt seasoning the extruder (canola oil on the filament).

    From in that location once everything mechanical has been verified I’d suggest rechecking all your settings in your slicer. You tin can employ coast to salvage back pressure at the stop of a layer just will take some tuning to get it figured out.

    I have not as I’m not sure how to add that in the mail processing script. I estimate I could add it manually to the gcode for test, simply non sure where it needs adding.

    From my understanding is there isn’t a style to modify it in EEPROM on the Dreamer. I have disassembled it completely and put information technology dorsum together last night with no luck and I made sure that the one screw that goes through the drive gear wasn’t too tight.

    I have not messed with coast at all. So far all I have washed is reduce retraction and retraction speed. Can’t actually reduce that much more than other than turning off lol.

    its like what Marking said above. Grinding filament is back pressure level. Either micro clogs with PLA, or the system is driving to much to fast. If your only getting to the 2nd layer I would tend to believe its because the extruder is not calibrated and so we accept to get that handled first.

    If your using Simplify 3D yous would open the gcode terminal (well any slicer really) and while connected over USB to your machine figure up your esteps, blazon in the lawmaking waldo gave you. Then say your esteps are 425. the code he gave was M92 425 Then you lot want to follow that with a M500 to salve to eeprom. Then try and extrude 100mm of filament and encounter what you become. If that doesn’t piece of work your in for some trouble. Quick googling shows a few groups that mod their FF machines then y’all’d have to notice how they are changing the firmware, get a copy of it, flash it with your correct esteps, and so see how the printer reacts. Sounds similar a agglomeration of crap to go through merely when companies close off their source it makes life…difficult lol.

    Information technology happens on the 2d layer on one model, but the other model is probably 20 layers into information technology before I see this problem.

    I volition try sending that lawmaking to the printer and see if it will save to the EEPROM.

    How do I tell it to extrude 100mm of filament?

    I’ve done some enquiry and I accept yet to find anyone that has changed the firmware of the Dreamer, but I may not know exactly what to look for.

    I volition start with trying to set esteps though and go from there.

    I really don’t want to have to change out the lath to something else and go through that procedure every bit I’thou not really familiar with that either.

    Ah okay, thanks! I volition effort this this evening.

    Still trying to figure all this out lol.

    Appreciate the help though.

    F is the feedrate. No clue what works on the Dreamer so you may have to play with that if information technology is too loftier.

    Okay sounds good. I volition post dorsum with the results!

    Thank you guys.

    I was actually able to test this sooner than expected. Information technology shows that the code was received in the terminal of S3D for the Dreamer, only it doesn’t appear to really be doing anything.

    It is extruding way less than 100mm when I attempt to extrude that amount.

    I’k assuming this means I tin can’t write to EEPROM since it has no result?
