@j3d the reason is that we want file uploads to be as fast as possible, and SD cards prefer large block writes; so RRF uses a 8K write buffer. In contrast, it's rare to download files from the Duet, and other file reads from the SD card don't need large blocks of data in one go; so RRF uses much smaller read buffers.

@j3d thanks for reporting that. I'm changing things in 3.4.0beta6 so that a power pin will not be assigned by default, and so io4.out will be free.

since your motors are rated at 0.8A they will get hot when you run them at at.
reduce the current to about 75% of the rated current.

also for extruder i found that spreadcycle produces better results.

i run all my stepper in stealthchop except the extruder.

; deployprobe.g
; called to deploy a physical Z probe

M280 P0 S10
G4 P200

wait for it to be deployed
as Z Endswitch i use 2000 on mesh 1000

@j3d
Glad you found a solution.
The speed setting in G1 moves are in mm/min while the calculations of the EMF tool are in mm/sec
So your setting of F60 might be very slow.
I doubt the leadscrews will be silent at F3600, but you will find a max. speed you can live with.

@Phaedrux I have sent off an email, yes.

C1 is intentionally not fitted.

I am glad you found the problem. Soldering the side-looking IR receiver can indeed be a problem because of the unusual location of the pads, and that is the first thing we check when a sensor doesn't respond to a nearby surface.

@j3d, which is best depends on the inductance of the motors and the VIN voltage. Do you have the motor specifications?

and there are 5v noctua fans which can be connected directly to the duet. even better there are 5v pwm noctua fans.
