(solved) Dual extruder E1 stepper confusion

I just installed a Chimera and have everything working with the exception of the second stepper driving the extruder.

Running the latest firmware.

The steppers on E0 and E1 are identical, as are the stepper modules (DVR8825). Both pots on the modules have been tuned and putting out the same voltage.

What happens when I do a test extrude is the E0 extrudes normally but the E1 extrudes incredibly fast and the amount extruded is about 30.2x the length it should be.

I switched stepper motors and modules around but still get the same issue.

I have the exact same settings for E0 and E1 in the config so this really has me scratching my head. Anyone with insight able to help?

Thanks!

Serial communications configuration ( baud rate defaults to 9600 if undefined )

For communication over the UART port, not the USB/Serial port

uart0.baud_rate 115200 # Baud rate for the default hardware ( UART ) serial port

second_usb_serial_enable false # This enables a second USB serial port
#leds_disable true # Disable using leds after config loaded
#play_led_disable true # Disable the play led

Kill button maybe assigned to a different pin, set to the onboard pin by default

See

kill_button_enable true # Set to true to enable a kill button
kill_button_pin 2.12 # Kill button pin. default is same as pause button 2.12 (2.11 is another good choice)

#msd_disable false # Disable the MSD (USB SDCARD), see
#dfu_enable false # For linux developers, set to true to enable DFU

Azteeg specific settings do not change

currentcontrol_module_enable false #
digipot_max_current 2.4 # max current
digipot_factor 103.0 # factor for converting current to digipot value
#51.0 for SD8825, SD6128, BSD4989

What happens if you switch the step ( and dir ) pins for each extruder ?
This sounds like you’ve got the wrong microstepping on one of the drivers though.

I’ll try the switch.

The DRV8825s are not digital so not sure where I would define microstepping for them?

(PS edited the original post with the config file)

Ok so I swapped the step and dir pins from one to the other.

As expected E0 and E1 movements get swapped.

Still have the same issue but it is now on E0 instead of E1.

Thanks for the help.

Well color me dumb.

I tried using one of the Azteeg Bigfoot drivers in the E1 and it worked perfectly.

Hmm…what was arthurwolf saying about microstepping?

I completely forgot that you need to put down jumpers onto the board with the analog drivers…problem solved!

Thanks,
