@lyndon Please post the full M122 output.

I've made a note to fix the truncation of M207 output when there are >= 4 tools in firmware 3.2.

It's a simple manual bed leveling macro.
So far I have 3 macros level test1 to 3.
first 1 homes Z then G30 S-1 at that X Y location then moves X Y to right side of bed and does G30 S-1 prompts for OK or Cancel. If result of G30 S-1 matched the result of probe position 1 then I cancel else I adjust the bed screw at that point then hit OK, which repeats G30 S-1 in the same X Y position.

2nd Macro doesn't probe position 1 since I now know the result from previous probing., it moves X Y to the 3rd probe position and then G30 S-1.
I repeat the above as needed calling macro's 1 through 3.
Based on the outcome of a G32 bed level test, I could run 1 or more of the macros again.
The X Y locations match the outer 4 points that G32 probes.

If that makes sence..

Thanks all for your replies I have it working now

@droftarts Yes mate, I have been changing tools recently from single nozzle 1 extruder to single nozzle 2 extruders, to 2 nozzles 2 extruders and diamond 3 extruder, So plently of tool definition changes and I missed the above. At least that's my excuse lol..

Ok I have now check mechanical and have to say I don't find any issues.
Next I will be mounting a DTI on the head and see if I can make progress or improve my understanding.
Can I ask, am I trying to probe the bed at the points where the nozzle would be? or does the firmware calculate for the offset ?

In my case should I be probing at X45 Y-55, and would this relate to nozzle X0 Y0 ?
Or have I been at this too long and brain freezing?????

@lyndon said in Simple tool change:

M104 S205 T1
M109 S205 T1
those are not valid RRF Gcode but AFAIK will probably not cause this specific issue (Use G10 to set temperatures, not sure how to get S3D to do this).

When a specific tool is selected (using Tn) the the TfreeN.g from the previously selected tool is run, followed by the TpreN.g of the tool being selected, followed by the TpostN.g of the now selected tool. So far so good, however did you have T0 or no tool selected when you started? if T1 is already active then sending the command again wont run the macros.

To test, from the console send T0, T1, T0 etc and confirm that the macros do what is expected.

Thanks all. I will have a read and probably come back with more questions
