Duet 2 wifi and duex5 bltouch not working
-
Could use some firmware advice as first time with duet used to marlin and klipper: Bltouch trouble with duet 2 wifi + duex5, the bltouch isn't powering on at all on this printer but works fine on my ender. I followed the betrue3d guide and duet3ds information for the correction for the out of date stuff but it's not powering on at all, genuine smart bltouch v3.1. I'm currently running reprap 2.0 firmware just because that was default for the configurator and not sure advantages of 3.0 or disadvantages, I'm also trying to get independent dual z with bed compensation but not working out so far to get them to sync, I can upload my config if needed.

@tsxfire Please send M115 to the Duet and post response (will show firmware version). Also please post your config.g, and a description of how the BLTouch is plugged into the Duet.
We're generally steering people towards RRF 3 now, and in particular the latest 3.1.1. It makes sense for new setups, so you don't have to learn the old way of doing it, then a new way. However, if you have a working setup in RRF 2 and don't need the extra functionality (see https://duet3d.dozuki.com/Wiki/RepRapFirmware_3_overview), just update to the latest 2.05.1. If you want to update to 3.1.1, you'll need to update to 3.0 first, then 3.1.1, and generate a new config.g and associated files for RRF 3 with the configuration tool: https://configtool.reprapfirmware.org/Start
General BLTouch guide is here: https://duet3d.dozuki.com/Wiki/Connecting_a_Z_probe#Section_BLTouch
Troubleshooting: https://duet3d.dozuki.com/Wiki/BLTouch_TroubleshootingI'm also trying to get independent dual z with bed compensation
That's going to be tricky without a probe! But guide is here: https://duet3d.dozuki.com/Wiki/Bed_levelling_using_multiple_independent_Z_motors

here are some images of how I have it wired in, and here is how I have it configured config.g based on just the configurator just updated to v3.11 per your reccomendation -
second update - after looking back over the wiring diagram again I found another jumper pin I missed, bltouch is now probing and onto figuring out the Z haha
-
@tsxfire looks like you’ve got a cloned Duet, in case you’re not aware.

@droftarts I'm aware, I wanted to dip my toes in the water with reprap and stuff before spending the premium for the nicer ones with higher quality and a friend had this to loan to me while I test and compare to my klipper/marlin experience, not sure why but after updating to reprap 3.11 it no longer detects my pt1000 thermistor

It's time to upload your config.g

I see it now. Could you copy and paste it into a post? It's not possible to view gcode files on mobile unfortunately.

just changed m308 "thermistor" over to "pt1000" and still not coming up for some reason

@tsxfire the M350, M92, M566, M203, M201, M906 may have only one value for Z, because XYZ are axis defined, so only one value each, E may have multiple values. The two Z actuators must have the same properties, M92 different steps per mm is not possible.
m208 x0:350 y-168:267
can be removed, because you define M208 some lines lower.G31 in most cases for BLTouch the P should be 25. The X and Y values must be set, otherwise mesh compensation will compensate at the wrong XY coordinates.
You have the same name e0temp for two termistors. For termistors P is used for the pin name: https://duet3d.dozuki.com/Wiki/Gcode#Section_M308_Set_or_report_sensor_parameters "P"pin_name" The name of the control board pin that this sensor uses. For thermistors it is the thermistor input pin name." There are examples at the end of the M308 documentation.
-
I left the g31 value as it was, and the z is actually working fine now, it's going up and down on the z without issues as well as probing with the settings listed above, but still haven't figured out why my pt1000s disappeared, they show up for half a second when initially booting but then it goes away for some reason....
-
@tsxfire it doesn't work like explained you define M308 wrong and double.
I would not let the wrong settings wrong, may have unexpected side effects.Please don't forget to set X and Y for G31 later, because often correcting at the wrong positions is worse than not using the G31 at all.
-
I just used configurator tool for that part, I have dual hotends which is why there is double. I'll adjust the g31 later but focusing on the little things functioning in general before I focus on offsets necessarily
-
also, the z having different variables is because I have 2 different motors - independent z - and one has a 16:20 tooth pulley setup while other has a 20:20 tooth pulley setup going into a t8 leadscrew, the settings I have set make it accurate to the mm for the z on that front from testing
-
@tsxfire as the documentation for M92 says, the second parameter is ignored:
https://duet3d.dozuki.com/Wiki/Gcode#Section_M92_Set_axis_steps_per_unit
"RepRapFirmware does not support individual motor settings where an axis has multiple motors connected to different stepper drivers. The first parameter specified will be used for all motors on the axis. You should use identical motors on any axis that has more than one motor to avoid unexpected behaviour.Example: If you have two motors on your Z axis, physically connected to Z and E0 stepper drivers, configured with M584 Z2:3, set M92 Z80, not M92 Z80:80"

The problem is not that you use two thermistors, but that you configure both with the same P parameter, which is used for the pin names (please see the documentation of the link I posted). Your config file says that both therminators are connected to one pin together, and the pin name is IMHO not correct. If you change the P parameters to the correct pin names and make the thermistor wiring to those pins, I expect it's working. Please use two pin connections, one for each thermistor.
The pin names are documented here:
https://duet3d.dozuki.com/Wiki/RepRapFirmware_3_overview#Section_Pin_names_for_Duet_2_WiFi_Ethernet
So bedtemp, e0temp and e1temp in your case for the P parameter. Only the
M308 S2 P"e0temp" Y"thermistor" T100000 B4138
needs to be renamed to
M308 S2 P"e1temp" Y"thermistor" T100000 B4138
then it should work. (But check that this thermistor is connected to the correct hotend...) -

It's possible, just a hassle, and an extra step that gets in the way of supporting people. I don't know about on Android, but on iOS I had to install a file manager (I used 'FileMaster' from AppStore). Then I can download a config.g file, send it to the file manager, then open it there.

Thanks. I hadn't heard of that one before.
