Ender 3 Pro RepRap config.g
-
I'm getting nowhere with the configuration of Duet2Wifi for an Ender 3 Pro. Both the bed and hotend show 2000c, as if it is an open circuit, even though they are connected properly. Endstops aren't working properly, so it can't home.

Morning.
Have you seen this? https://duet3d.dozuki.com/Guide/Ender+3+Pro+and+Duet+Maestro+Guide+Part+2:+Configuration/38
This has helped me lots and still does with my Ender3 Pro, it was written for the Maestro.Is it a stock Ender3 Pro with no mods other than the Duet WiFi?
This is my config for the bed
M305 P0 T98801 B4185 R2200
Make sure you change the 'R' value to 4700 for the Duet2If that does not work, use a ohm meter to make sure there is a resistance to prove that the cables are crimped and in contact.

The T values in your M305 commands are wrong. They should both be 100000 or close to that value. That is why you are not getting readings from the thermistors.
The R values in those commands ate not needed because the firmware knows the correct value.
See the link in the post above by @PaulHew for detailed instructions.

The config.g is what the RepRap Configuration website gave me. So I should change all the T values to 100000 in the config.g file?I changed the endstops to S1 and finally got the endstops to work.

I suggest you follow the link in the earlier post, because that will show you the correct values to use in the configurator.

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.gCan'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.

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.

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.

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 I1What happens if you put the probe into self test mode using
M280 P3 S120 I1 -
@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. -
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.
-
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?
