SET_LED LED=mmu_leds INDEX=0 RED=0 GREEN=0 BLUE=0 TRANSMIT=1

[CopOsiris]

I get the error when starting the printer/MMU
Error running _MMU_SET_LED: Error on 'SET_LED LED=mmu_leds INDEX=0 RED=0 GREEN=0 BLUE=0 TRANSMIT=1': INDEX must have minimum of 1

If I do MMU_LED...
`LED animations: enabled

What is your led configuration in mmu_hardware.cfg?

Also, what version of Happy Hare does Mainsail or Fluuid say you are running? In the form v2.7.1-56

[CopOsiris]

happy-hare
v2.7.1-59-g84ba4f32
mainsail
v2.12.0

(comment out this section if you don't have leds)

[neopixel mmu_leds]
pin: mmu:MMU_NEOPIXEL
chain_count: 6 #7 # Number gates x1 or x2 + 1 (if you want status)
color_order: GRBW # Set based on your particular neopixel specification

[mmu_leds]
num_gates: 6
led_strip: neopixel:mmu_leds
exit_range: 5-0 # 0-5
#entry_range: 7-12
status_index: 6
frame_rate: 24

[moggieuk]

Ok. So chain_count should be 7 (because you have 6 exit and the status). I.e. 7 leds in chain. Then define as:

exit_range: 6-1
status_index: 7

[CopOsiris]

The solution was
[mmu_leds]
num_gates: 6
led_strip: neopixel:mmu_leds
exit_range: 6-1
status_index: 0
frame_rate: 24

Putting this gave me an index error because it could not be greater than 6
exit_range: 6-1
status_index: 7

[moggieuk]

So how many LED's do you actually have connected? If only 6, then you should comment out the status LED else you will have problems later.

[CopOsiris]

I'm only 6. I'm going to comment on the status_led...Tonight I'll tell you how it goes
