OK, so I got the ooznest workbee firmware and web interface working and sucessfully was able to set the 0,0,0 location for my workpiece.

Now what I would like to do is be able to tool change and set the new z=0 value for the new tool. Obviously, now that I have machined stock, I can no longer use my probing piece that I set on the corner of my stock when I started.

I assume that after I setup the initial tool on top of the workpiece, I will have to move my probe calibration plate to directly on the table, probe a point, store and store the offset so I can recalculate Z for the second tool.

When I change tools, I would probe the calibration plate and recall the offset from the original and apply it to the second tool. I have no clue how to do this.

Help please.

On a side note, do you use the same input on the duet for both touch plates?

Thanks Danal, as a follow up, could you share with me a small list of the g/M codes that I would need to use to create the macros? That would give me a place to start researching. I am very familiar with 3D systems as I run an inspection lab where I work and program optical inspection systems as well as CMMs and other instruments. I also have a background in CT scanning and post processing of CT data. I just need a place to start.

I will Pseudo code my thoughts as to how to approach the above and run it by you to make sure I am on the right track before I start to attempt to code all of this.

Thank you so much for your help. I was feeling rather lost.

@Danal , So before I try all of this, I assume there is a way to set Z0 when doing a tool change when the top of stock is no longer there, i.e. if I did a 3D adaptive clearing, I no longer have anything residing at top of stock?

It would be nice to have a small window with probing options. Maybe buttons for probe X, Probe Y, Probe Z (with offset capability) and set work coordinates. In addition, macros for each that the buttons call to perform the task. Would be nice to be able to call the macros during run as part of gcode file or use them manually

I am relatively new to the CNC community, I build a Duet Wifi control system to run on an openbuilds CBeam hardware platform. I have limit switches only on the homing side of each axis.

I am having trouble understanding the work flow to setup a job. I am thinking that this should be the sequence in setting up a new job but would appreciate a little help understanding

• Setup 3 tools in Fusion 360 CAM and use them all, 1 for each cam setup.

• Manually Probe X, and Y of the workpiece front left corner and set the G54 o,o position to these probed coordinates.(I am thinking to set the probe position at the corner of the workpiece and CNC the probing. Not sure what probe system to use)

• Probe Z(I think on the bed since I will have to do manual tool changes during the job.)

• After first operation, have the machine move to a location where I can change the tool with the motors locked.

• Change the tool. acknowledge the change, and have the tool automatically set the z 0 position and create the proper offsets so it is relative to the first tool.

I have searched alot and have not really found anything.

I recommended workflow with suggestions for gcodes and probing harware would be so helpful if someone would be gracious enough to guide me.

Thanks

Dave
