What happened?

Controller seems to be dead. It is no longer causing axes to step, but can still be programmed, communicated-with, etc. (i.e. it doesn’t know it’s not stepping.)

Installation and configuration began last night. Last night and today controller was showing these LEDs:
!image
Motor 2 (Y) never had Enable LED on and the axis was locked when not moving, but was moving correctly.

Shortly after it was showing this and axes weren’t working:
!image
Only axes 1+2+3 are configured, but axes 3+4+5 have illumination. I tried re-uploading the config and rebooting, but no joy.

It then became this:
!image
Tried full erase, install-fs, install-wifi, but no change.

Before I had to run out, I tried moving X-axis to motor output #4 (see different I2SO assignments) but still no movement. It’s dead.

Side note: I wish this controller was available with modular (‘disconnectable’) connectors.

#1 – MitchBradley 于 2025-01-15

Ouch. Based on all the lights being on, my initial suspicion is that the shift register chips died.

#2 – daxliniere 于 2025-01-15

Yeah, I was pretty bummed.
I have some a basic SMD hot air station, is it worth trying to replace them?

#3 – daxliniere 于 2025-01-15

The parts are cheap, but the handling fee makes it a bit crazy.
TSSOP package, right?

#4 – MitchBradley 于 2025-01-15

If you have a logic analyzer you could first do a test to see if they are getting an I2S signal. If not, the problem could be elsewhere.

The way to check with a LA is to tack wires onto the i2s gpios and look for clocks and data.

#5 – MitchBradley 于 2025-01-16

If you have only a scope, you can look at them individually. bck/gpio.22 should have a fast clock in the 32 Mhz range. ws/gpio.17 is slower, in the 1 MHz range. data/gpio.21 has a waveform that depends on what is being sent to the chips, with a minimum pulse width of one full cycle of bck.

#6 – MitchBradley 于 2025-01-16

If you are using a recent version of FluidNC, you can control the clock rate with minpulseus in the i2s section.

#7 – bdring 于 2025-01-16

I can authorize Elecrow to replace it if needed.

#8 – daxliniere 于 2025-01-16

@MitchBradley Unfortunately a multimeter is all I have in terms of test gear.

#9 – daxliniere 于 2025-01-16

@bdring, yes, perhaps a replacement would be best.

#10 – bdring 于 2025-01-17

What is your order number with elecrow?

#11 – daxliniere 于 2025-01-17

Order# 237616

#12 – bdring 于 2025-01-17

Contact them about getting a getting a new one. I have authorized a replacement.

I am closing this issue.

Thank you for sorting this so quickly, Bart. 🙏
