BLTouch giving error

terhart

Hi,
the (original Antclaps)BLTouch sensor on my printer is giving problems.
When I use the G28 command or home the Z direction, I get the error: G28 Z Error: Bad command: probe
I tried to find the reason for the error, tried different versions of the firmware, nothing works really. The error stays.
When I use the command M280 P0 S10 / M280 P0 S90 no error occurs.
Using M401 P0 and M402 P0 give an error.

Does anybody have an idea of what I'm doing wrong here?
Thanks a lot for your help.

=========================================================================
This is what the system looks like:
Board: Duet 2 WiFi
Current firmware version: 3.4.1
WiFi Server: 1.26
Web Control: 3.4.1
I tried other (newer) versions but that makes no difference, error stays)

The macros use M401 and M402

jay_s_uk

@terhart post your homez file
M401 and M402 should just be M401 and M402 with no P0 at the end

droftarts

@terhart @jay_s_uk M401 and M402 should be able to take a P parameter; see https://docs.duet3d.com/User_manual/Reference/Gcodes#m401-deploy-z-probe

However, this sounds like a bug, and that it is looking for deployprobe0.g, and when it does not find it, it is not switching to deployprobe.g. I've marked this as a bug for @dc42 to check.

Did you modify your deploy and retract macros to remove the P0 from the M280 commands?

terhart

@Phaedrux Yes, I did. But unfortunately it didnt solve anything. Error stays.
Thanks for your help.

terhart

@Phaedrux Next to my previous remark: This is exact error text that is generated:

M98 P"0:/macros/BLTouch Retract"
Error: Bad command: probe

There is no error on the deploy macro.
Also, if I initiate the command "M280!P0 S90" or "M280!P0 S10" the BLTouch deploys and retract without an error.
The error only comes on M402.

Thanks.

Phaedrux

deployprobe.g and retractprobe.g must be in the sys folder for M401 and M402 to work. They must be named that way too.

@terhart said in BLTouch giving error:

M98 P"0:/macros/BLTouch Retract"
Error: Bad command: probe

We'll need to see the contents of macro file "BLTouch Retract" to diagnose that.

terhart

@dc42
Hi, thanks for helping me.
This is all that is in the BL Touch Retract file:

M402

If I just enter M402 on the command line, a "probe" error is raised.

Best regards,

Hans ter Hart

Phaedrux

retractprobe.g deployprobe.g

Try placing these files in your sys folder.

THANKS!!!! That did it....!! Problem solved! No error anymore.
Thanks a lot for your help.
