BLtouch and Railcore 300ZL problems

ObiWan2Print · 27 Jul 2021, 01:06

I have spent many hours reading past post on here and implementing possible solutions. So far the BLtouch does not respond to commands. Would really appreciate any help the community could provide. I am using RepRapFirmware for Duet 2 WiFi/Ethernet version 3.0 running on Duet WiFi 1.02 or later + DueX5. The latest version of BLtouch. My config file is :
; Configuration file for My Printer

So the BLtouch does power up and extend and retract when powered up. However, it does not respond to commands. Any suggestions?

@obiwan2print

Here is my config for BLTouch - will not directly apply to you:

M950 S0 C"duex.pwm5"                                ; create servo pin 0 for BLTouch
M558 P9 C"^zprobe.in" H2 F120 T12000 R0.2 A1 S0.03  ; set type for BLtouch and set default parameters
G31 P25 X0 Y24.5 Z2.660                             ; set trigger value, offset and trigger height (larger = closer)

I don't see where you have created the servo pin needed to control the BLTouch.

This syntax is for RRF2, not RRF3. The lines provided by @fcwilt are what you'll need to use for RRF3. Your deployprobe.g and retractprobe.g will need to be updated as well.

Update your firmware to 3.3.

https://github.com/Duet3D/RepRapFirmware/releases/download/3.3/Duet2and3Firmware-3.3.zip

Upload this zip file to the system tab in DWC.

You can check if it's all applied correctly by sending M122 afterwards. You can also check your config.g for other syntax errors by sending M98 P"config.g"

@phaedrux what commands should be in the updated version of deployprobe.g and retractprobe.g ?

@phaedrux Now I can't get the Z axis to home. The BLtouch probe lowers and the print head moves but the print plate Z axis does not move. It also says the S commands are old and should be H command. Any suggestions on how to resolve this problem?

ObiWan2Print · 30 Jul 2021, 00:45

@obiwan2print I am using the G28 Z command to try to home the axis or the home button in the console.

Please cut-and-paste your config.g, homeall.g and homez.g files using the </> tag.

Thanks.

Also you can just change the S parameter in the G1 S# commands to G1 H#.

@obiwan2print

The problem with using a Z probe to home Z is that you need to move to a fixed XY position.

To do that X and Y have to be homed first.

Which means G28 will work (since you home all in the order XYZ) but G28 Z may not work.

That's one of the reasons I don't home with a Z probe but install a Z endstop as well as the Z probe.

I think you should probably generate a new config from the online tool so you can see what the proper heater setup format looks like in RRF3.

@paulhew thanks for this help and information. Still trouble shooting the Z axis configurations and movement. Hope to resolve those issues soon.

ObiWan2Print · 23 Aug 2021, 23:15

@fcwilt When I use the G28 Z command the nozzle goes to the back right corner and stops with the BLtouch located off the print platform. I would like to move the nozzle in the negative Y direction in order to have the BLtouch on the print platform. Any suggestion on how accomplish this task? I tried changing the G31 Y offset value in the config.g but it still homes to the back location when using G28 Z.

@obiwan2print

When jogging the axes using the jog buttons in the DWC does each axis move in the correct direction?
