BLtouch and Railcore 300ZL problems

@phaedrux thanks the helped !

@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 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.

@ObiWan2Print Just incase You need some help, these are the files from my RailCore running a Duet Mini 5+ with 1LC toolboard. RRFv3.3.0

If I can help further, please let me know.

@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.

fcwilt · 24 Aug 2021, 00:35

@obiwan2print

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

The position it goes to is defined in homez.g. If it's not going where you want it, you need to edit that file.
