Had a couple of issues with that links configuration. The Bed heater is now working but the hotend is still reading 2000.

Please tell us what the issues were (so that we can improve that wiki page), and post your config.g file as it now is.

The x motor homed to the right instead of the left.
The z motor homed up instead of down.
I switched those from S1 or S0 to S0 or S1 in the config.g

Can't figure out why the hotend is still reading 2000c.

I have a Micro-Swiss hotend and Bondtech extruder setup in direct drive configuration, with a BLTouch.

Check that you have the hot end thermistor plugged into the correct connector, the E0_THERM connector. See https://duet3d.dozuki.com/Wiki/Duet_2_Maestro_Wiring_Diagram. If it's definitely in the right connector, it's probably a bad crimp connection or a break in the thermistor cable. You can temporarily plug the bed thermistor wire into E0_THERM to check that the thermistor port is working.

. Ok, had a bad crimp. The hotend temp is now working. I have a Duet2Wifi those instructions are for a Maestro, are they the same config wise?

They are almost the same, except for the R value in the M305 command, if you have one. R4700 is correct for the Duet WiFi.

Now I just need to get the BLTouch working properly. It seems to home ok, but the BLTouch alarm comes on every time I home, and the M280 P0 S160 Alarm release isn't working.

M280 P0 S160

That implies that you have the BLTouch connected to the Heater 0 output, which isn't right. Use the same P value in that command that you do in the deployprobe.g and retractprobe.g commands (usually P3 or P7).

I am not an expert on BLTouch, but I think it may help to add parameter R0.2 to your M558 command in config.g.

@dc42

None of that worked.

Are saying that M280 P3 S160 doesn't reset the BLTouch error?

Do M401 and M402 commands work (they should deploy and retract the probe)?

Please post your homeall.g and homez.g files.

M401 works M402 retracts but the alarm comes on.

M402 retracts but the alarm comes on.

I think you may have a damaged probe, or the pin may be bent. There is a set screw at the top of the probe body that you can remove to get the pin out and check it.

You need the I1 at the end of the command to release the alarm. M280 P3 S160 I1

What happens if you put the probe into self test mode using M280 P3 S120 I1

[keith]

@phaedrux
All the other BLTouch commands work fine. Self test, retract, deploy, etc... It's just the M280 P3 S160 I1 that doesn't work.

[A Former User]

Could it be the command actually works but the sensor goes back into alarm straight away? Seems odds only S160 wouldn't work if the probe is working properly.

[Phaedrux]

Recreate the retract probe file from scratch just to be on the safe side.

When it's doing the self test the probe goes in and out repeatedly no problem?
