RRF Configurator questions...



  • I hope this is where I can post these questions.

    I think I'm all wired up and ready to get back to setting up my machine. I'm trying to use the online configurator;
    https://configurator.reprapfirmware.org/

    I have tried to figure this out, but I know my BL Touch settings aren't right and I'd rather post again than trust to luck. (cost me $65 last time..)

    I'm trying to find these specs online but I just can't seem to figure out any calculators or direct numbers that seem to correlate to what's being asked on the configurator. I've perused through the duet3d docs, but it's really confusing to me (for now) and again, the terminology seems to be beyond my current understanding..

    SO, that all being said, here's what I have.
    BLV Mod frame with 2 Z Stepper motors.
    V6 Hotend Not clone
    BL Touch Not clone
    Duet3D Not clone
    Stepper Motors Model; j-4218hb2401
    here's a link to some specs on the motor (what I could find) https://www.aliexpress.com/item/32817779500.html
    I'm using a 12V power supply
    Wiring is verified by others on this site

    I know this is a lot to ask, but I'm not trusting my understanding at all at this point until I learn more. I'd just like to get my printer up and running and learn along the way. Thank you all!!

    Here's a shot for shot of the configurator and what I'm trying to figure out..

  • motor current should be 75% of the rated current.

    your thermistor values are wrong for an e3d v6 and probably for your hotbed.

    fan0 should not be thermistatic controlled.

    z steps of 2560 is almost certainly wrong

    e0 steps need to be calibrated..

    probe x y offset are not defined.
    trigger height needs to be measured.

    whats your reason for going with a 12v psu and 1.8 degree steppers on the blv?

    @hbrownell, please post the config.g file that the configurator generated and you uploaded to /sys on the SD card. Most of us find config.g files easier to read than screen shots from the configuration tool!

    Motors:

    • for the motors you mentioned I'd start with 1200-1300 mA
    • 100 steps/mm doesnt look right to me please refer to this calculator to get the relevant values for your specific setup.
      same goes for Z steps/mm
    • steps/mm on your extruder can be calibrated after you are setup:
    1. measure and mark 150mm of filament from a fixed point (i.e. extruder body)
    2. tell your printer to extrude 100mm of filament
    3. measure again to determine the actual amount of filament extruded
    4. calculate your new steps/mm using this formula: <current steps/mm> / <actual amount of filament extruded> * <length you wanted to extrude(100 mm in this example)>

    Heater config

    • for your V6 if you got the standard kit the values should be R25=100000 B=4725 C=7.06e-8
      But please look here for more detailed information to double check.

    • for your heatbed, you will have to look up your specific model and the type of thermistor used. Check the datasheet of that thermistor to get your values.

    BLTouch:

    • Probe X and Y Offsets are the distance from your nozzle to the BLTouch, this depends on your mounting solution

    • Trigger height is the distance from your nozzle to the bed once when the BLTouch triggers, this is also unique to your config and needs to be measured.

    Fans:

    • Fan0 should be your part cooling fan and should not be thermostatically controlled
    • Fan1 config looks fine, if it does not work, try changing the PWM frequency.


  • @jv43 The Bed was an A8 replacement,
    It is 1% 100K 3950 300℃. - from the rep

    I am running a 16 tooth pulley for the belt, so the number that I get says 100 Steps pM, is that right?

    yes



  • @dc42 does the configuration look ok? Should I start it up like this?

    You should not have a M587 command in config,g. It won't work there anyway. Other than that, I didn't spot anything wrong with it.



  • @dc42 Thank you! On to the next round of troubleshooting.
