Z_probe issues with Anet A8
-
@Jagofletch said in Z_probe issues with Anet A8:
have an NO probe, so M558 required the "I1" command to invert the signal
I1 is a version 2 command. inversion is done with !
if the z probe is always triggered there is a problem wit your wiring.
-
The motors weren't engaging with ! but they've started working with the version 2 I1
My probe isn't always triggered. It will trigger (LED on) when it senses the bed, as you would expect. I've checked the wiring for the Z probe multiple times but I will have a triple check.
-
the relevent information about triggering is what m119 reports
-
Sorry, I must've deleted that from my last reply.
M119
Endstops - X: at min stop, Y: at min stop, Z: not stopped, Z probe: at min stopI'm wondering if it may be that I'm using the wrong diode from the Probe in
-
if that is an npn probe
Duet 3, Duet 2 Maestro, or revision 1.04 or later of Duet 2 WiFi or Duet 2 Ethernet: you can connect the output of the sensor directly to the Z-probe IN pin.
-
I have 12v feeding the sensor, can the Z probe in handle that voltage? I'm not entirely sure what an NPN outputs on its signal wire.
-
see
https://duet3d.dozuki.com/Wiki/Hardware_Overview
PCB revision v1.04
The Z probe input improved to tolerate inputs up to 30V.so just make sure you have revision 1.04
-
if you are not sure if your probe is npn why did you wire it as npn?
-
Oh I was sure it was NPN. I'm just very new to Duet and there's a lot of info I'm having to juggle. So I may not be putting my point across properly.
-
Can you post the results of M122 to check the firmware version? Also post the results of M98 P"config.g"

Your config is trying to use the command syntax for RRF3 but you only have RRF2 installed. I suggest you update.
If you still have access to DWC. Upload these 3 zip files, one at a time in the system tab. Don't extract them. Reboot after each. Use M115 to verify the firmware has been applied.
https://github.com/Duet3D/RepRapFirmware/releases/download/2.05.1/Duet2Firmware-2.05.1.zip
https://github.com/Duet3D/RepRapFirmware/releases/download/3.0/Duet2and3Firmware-3.0.zip
https://github.com/Duet3D/RepRapFirmware/releases/download/3.2/Duet2and3Firmware-3.2.zip
That will get your firmware and DWC up to date.For your config, might be a good idea to run through the configurator tool and generate a fresh set for RRF3.

If anybody else is reading this and having the same troubles I will be back to post my methods for getting everything working. At the moment I have had some troubles with upgrading from 2.x to 3.x, that's now sorted, but it has messed with my configuration. Some of the axis don't respond, the probe still doesn't register and the axis that do work are reversed (even reversing the direction in config.g doesn't solve the issue). I have a few weeks of freelance work before I can get back to it.
