Hi,

I have this problem where my duet will not boot, here is a copy from YAT:

I have tried many SD cards and formatting these as described in manual but I can not get it to work. This board was bought on reprapworld but they dont exist any more.

Does anyone have some ideas?

Hello,

I am making one large 3D printer as you can see on images that I have attached. Everything works fine except I have some weird effect on Y axis ( dual Y). Using Duet 3 board with latest firmware. config.g
Extruder is e3d titan aero with supervulcano hotend.

When printing rectangle parallel to axes, as you can see on photos attached, walls are not touching on Y axis but on X axis everything is fine.

When printing some radius then walls come out some pattern in which one is shifted left and the next one is shifted right.

Things I have tried up till now:

1. Tightening belts, equal force on Y and X axis
2. Reinforcing Z axis

Does you have some ideas, is this software or hardware issue?

@Phaedrux Thank you this worked.

This is result of G31:

Z probe 0: current reading 0, threshold 500, trigger height 0.700, offsets X0.0 Y0.0

This is from config.g:

G31 P25 X-38.2 Y-11 Z1.447							   ; Set Z probe trigger value, offset and trigger height

@DIY-O-Sphere Those are for headed bed, PID tuning.

@Veti said in Nozzle to high when printing BLTouch:

M574 Z2 S1 P"io4.in" ; configure active-high endstop for high end on Z via pin io4.in

I have removed it but nothing changes.

I'll make those changes for y axis for now it works.

Should I eliminate z endstop switch? Can i use it for homing but instead of z probe homing? But I would still like to use mesh bed compensation?

@Phaedrux Alright, thanks.

Tried that but noting happens, its like this offset is ignored.

@Phaedrux Yes I used this one. It took 4 hours to complete but it was successful.

Hi,

I have issue that when I do z probe in home all when i go to G1 Z0 nozzle is 1mm away from build plate, so when print starts it is 1mm higher than it should have. I have done Z probe calibration many times. Mesh bed compensation also. Baby stepping does not work also I put even -0.5 but nothing happens, but it triggers some error that printer is out of limits... Any advice would be great. I am using latest beta firmware.
