HELP with configuration
-
Hi everyone,
I raise you a series of doubts that we don't know how to resolve regarding the development of the machine configuration after the hardware is almost near to complete:
-
How to establish the offset of the heads, in relation to their head base and their respective situation in their dock and with respect to the bed. The center of the bed is X0 Y0.
-
How the Z probe behaves in terms of offsets with respect to the heads. It would be possible to make the topographic map independent of the bed of the tools (do G29 without tools, since the probe is in the Z axis that can move without tools, for example), just do a bed map without tool related offsets.
-
How to set the length of the nozzle in a button in a fixed position on the bed for each of the heads according to their head offsets? Each head has a different length.
-
How to establish the offset of each tool head and how to do with the head switches to interpret which tool it is and what position it has within the head base. For this, each head has two microswitches connected to io1.in and io2.in in each 1LC. And each head dock has a different combination of lugs that push the head switches (dock1: on-on / dock2: on-off / dock3: off-on).

Now, all the movements are simultaneous so the probe once deployed touch the firts point and stay there reporting error:

With more time, we will learn it but now we are a bit in a hurry.

Just trying to clear some brainspace to digest your large post. It's on my list.

@phaedrux I know it's dense. Please ask me anything to help to clarify any part.
Thanks a LOT!
One of the things we are battling now is to make it work the G29 S0 mesh grid. This video show the behaviour of the home all followed by a failed G29 S0.
The XY and Z axes moves are combined with the probe deployed to the first point but it sink the probe before reach the XY move. Ideal would be reach the first position in XY coordinates and after that, deploy probe and lower Z axis to contact first point. After that, move Z up (10-20mm), move XY to next point, low the Z axis and trigger the probe signal, and so on.
As you can see in the video, it can't do at first probe point. At the console can be seen this error:

@dc42 May could you able to read this entry?
Can you give us some hints about the question asked?
