Yes this is on a Tevo little monster. What could remove these artefacts?

Regularly spaced lines at 30 degrees to print direction only on right side of print. Suggestions?

Many thanks for the help. M401 and M402 didn't do anything - I checked those two files carefully against https://duet3d.dozuki.com/Wiki/Connecting_a_Z_probe#Section_BLTouch.

Issue was that in the deployprobe.g and retractprobe.g files, retract should have been M280 P3 S90 I1 (originally M280 P3 S90) and extend/ deploy should have been M280 P3 S10 I1 (originally M280 P3 S10). Once that was fixed, it worked!

For those with the same issue, beware what RepRapFirmware Configuration Tool generates!

Still have the same problem.

I have checked the wiring and it is wired the same as the duet board of my friend that works. I have checked with his duet on my board and have the same problem. The resistance between the two pads on the bltouch is around 330 ohms after making sure the trace is cut.

I have set the bed height to be z=0 using a piece of paper and jogging the print-head up and down. So the Z-probe trigger height should be correct no? How do I check/ set what the probe trigger height is?

Is my Duet Wifi broken?

I have wired up a BLTouch as a Z-probe for my delta printer (see picture). I have cut the strip connecting the two pads on the BLTouch to make it 3.3V logic and used the Reprap configurator to generate all the necessary files. On startup, the BLTouch retracts and extends out its pin as it did with the MKSBase board I had before, the LED is off when pin is extended and red when pushed in by hand (after startup).

However, it does not trigger when the pin hits the bed (checked with G30 S-1 and printer stops at z=0 with an error saying 'Z probe was not triggered during probing move. Stopped at height -0.000mm').

Is my config.g wrong or is it my wiring (BLTouch was working when used MKSBase so do not think that is the issue).
