New hemera settings



  • 20201002_101811.jpg 20201002_101703.jpg
    Can any one tell me what im looking at
    I get the same line or thickness change every print and the tip if the bow tends to curl up
    I believe they are two seperate issues



  • Before i intaled the hemera it made perfect benchies
    I also had lines missing in the same spot each print
    Could this be cause of an upgrade it matercontol ??

    its a good idea to never change more than one thing at a time.

    what was your extruder and hotend before the change?

    post your config.g



  • I ised a microswiss coppy of the cr10 design it was a straight swap hreat hotend 😊

  • Looks like you could have a hotend temperature issue. Did you also change the thermistor? If so, verify your thermistor settings are correct.



  • @ziggymanpopo said in New hemera settings:

    M305 P1 x501 R4700 ; Set thermistor + ADC parameters for heater 1

    e3d does not offer pt1000 thermistors. they offer pt100.

    ; M307 H1 A245.3, C121.7, D4.0, S0.5 ; PID

    you have not done a pid tune for the new hotend?

    M574 X1 Y1 Z1 S1 ; Set endstops controlled by sw. Z controlled by capasitive sensor

    this does not configure a probe.
    a probe configuration looks like this

    M574 X1 Y1 S1 ; set active high endstops
    M574 Z1 S2 ; set endstops controlled by probe

    M305 P0 T100000 B4138 R4700 ; Set thermistor + ADC parameters for heater 0

    your bed thermistor setting is wrong



  • What is pid ?? and how is it tuned





  • The termistor is actually a sensor the original was defective no replacement available my bad
    I believe tos a pt1000 otherwise i would need a daughter board i have two china laser tem sensors
    But.dont believe they are accurate by any means
    They read 10° hotter than the bet ten on the dwi
    Wouold it be nessicary to buy a fluke multimeter with a calibrated sensor ??? I have no idea.
    Anyone have a link to pid need to learn how to set it for the hemera and the best and most reliable method of calibrating both the hotend and the.bed



  • Thanks i think i have more than.one issue since it was a complete rebuild i think yournspot on about the pid. No idea exactly wat it iis im also driving blind with the temp calibration since the temp sensor is frome a difernt store because of nessecity
    It will be some time untill they are back in stocknat e3d



  • The store i boght it from uses the same sensir in there unitsnthey buils and use duets forncontrol board thats wher i got the gcoad entry for the sensor.what they use again im an electical comtractor (big on a meter thas calibrate)

    Does the software make an allowance for drop of temp from whats indecated and the actual bed serface??



  • Fyi my z- probe is my nozzle thats why the neg z-prob offset 🙂



  • you can gat semitec thermistor from other stores.
    https://www.aliexpress.com/item/32847452724.html



  • The sensor is working fine and maintaining a set temp
    I think it's off ,,just not sure which way or how much
    I checked the link that explained some of it,, theres another link within explainig the process of how so thanks for that ..
    i saw somewher that it was recomendermd running the hemera 5 to 1O° cooler temps because of efficiency??
    I know for sure that some things chainge with direct drive pressure advance ???
    How does that work and fit in with an upgrade???
    Such as extruder steps and retraction,, like in my case ,,what else? Would be required to be changed and calibrated??? Or maybe looked at
    Thanks 🙂



  • Im noticing yout pushing the PT 100 in stead of the
    PT1000 ive read the Pt100 give beter temp accuracy
    Is that why ?
    Wont the pt 1000 do the job just as well as the 100
    And without the need of the motherboard?



  • who is pushing the pt100? i just said that e3d does not sell them.



  • No offence intended should have said picked as an example,, just fishing ive read lots not sure what applys,, i have no idea what would be the best chioce that's the only way to learn just an expression:)



  • @ziggymanpopo

    i use pt1000 myself.

    we are just trying to figure out what you have changed, as you never mentioned the pt1000 and the hemera does come with a different one



  • Yes.. my bad thats why the storie about the backorder E3d was out of the original termistor
    Thats why the pt1000 sensor i knew it wasnt the same but it works great at some piont i would think a calibration is warranted would you agree considering ive changet to the sensor.. i have faith the gcode has the right information just not sure it correct givin my frankenprinter lol. 🙂 and the benchy at the top of course



  • My question is not as much how do i fix it as how do i check it ??.. if that makes sense ??



  • pt1000 sensor do not need calibration. their properties need to be the same.

    does your pt1000 sensor come in the cartridge format that fits fully in the e3d hotend?



  • Im missing something guys no idea what but if i set the temp to 205 it runs nicely up to that temp as far as the displayed temp goes the results make me question the actual temp..



  • And yes x501 is the correct entry given by the supplier for the sensor also the r factor



  • Yes indeed also put a small amount ik f heatoastvon it befoyr i slid it in,, good fit
