@crap Yeah, I'm not too familiar with CNC. Since RRF is primarily oriented to 3d printing, I think some of the CNC functionality might be a bit behind the overall industry.

@Jengland I do have it
I use the following method:

I set the machine zero with setter and spindle without the tool / collet / nut I install the tool I test the tool and set tool height

If I change the tool, I just redo p2 and p3

It does require additional step on the machine enable (p1), but It happend that my setter is +- 0.01, and Z endstop about +- 0.1-0.3

My script

M208 Z8 S1 G53 G90 G0 X321.0 Y0.0 if !exists(global.MGlobalsLoaded) M98 P"/macros/Measuring/globals.g" ;M558 P1 C"io7.in" H23.258 F{global.MSpeedFast,global.MSpeedLow} M558 F{global.MSpeedFast} K1 M300 S300 P1000 if state.currentTool = -1 M291 S0 T5 P"Probing the spindle zero height" else if global.HSpindle <= -9999 abort S"Please set the spindle zero first" M291 S0 T5 P"Probing the tool " ^ state.currentTool ^" offset" M558 F{global.MSpeedFast} K1 G30 S-1 K1 G53 G1 Z{move.axes[2].machinePosition+2} H4 M558 F{global.MSpeedLow} K1 G30 S-1 K1 if state.currentTool = -1 G92 Z{sensors.probes[1].diveHeight} set global.HSpindle = sensors.probes[1].diveHeight set global.MResultZ = sensors.probes[1].diveHeight M208 Z30 S1 else M400 echo "Probe triggered at Z:" ^ move.axes[2].machinePosition ^" Sensor height: " ^ sensors.probes[1].diveHeight var ToolLen = move.axes[2].machinePosition - sensors.probes[1].diveHeight set global.MResultZ = - var.ToolLen M98 P"/sys/tool_set.g" T{state.currentTool} O{global.MResultZ} ; Set soft limit to 0 plane M208 Z{var.ToolLen} S1 M558 F{global.MSpeedFast} K1 G53 G1 Z{move.axes[2].max - 10} H4

Endstops already telling that they were triggered was the thing. Thank you!

@menthos I have updated the documentation at https://docs.duet3d.com/en/User_manual/Reference/Gcodes#m675-find-center-of-cavity.

This might provide a possible solution. https://github.com/rclone/rclone ??

Definitely want to avoid having to reinstall everything again in the event of an SD card failure!

And here are the sys files.

@sdj tpre2.g tpre1.g tpre0.g tpost0.g tfree1.g tfree0.g Probe.g config.g

So it's working 🙂 I switched the Endstop of the Y-Axis to Y Positive and inverted the endstops in the configuration.

@p0rr1dg3 I have an Ooznest Workbee CNC. It is configured with soft limits which prevent the machine from moving outside the machine limits.
What version of Duet Web Control are you using?
In CNC mode, we have machine coordinates (the actual physical limits of the CNC) and work coordinates, which are job specific.
When you set your X0 Y0 and Z0 they fall within the machine coordinates and you will get an error notification when the machine is given a command to move out of bounds.
Your work coordinates CANNOT exceed your machine coordinates limits.

Edit
I see you're using very old firmware. Please upgrade to the latest stable firmware and your issues will be solved.

@jay_s_uk thanks for this great link.

@nightowl after solving some other issues I made my own configuration with RRF and compared it with your config. Now i made the upload and have to wait until i am in front of my machine.

@jay_s_uk thanks..

that is a real bummer... so much wasted potential...

@cncmodeller That's probably a better aproach then the heater/thermistor idea in the other thread, but it would require FW adaption.
A spindle definition would then be a combination of Fan.rpm reading and heater PID algorhythm.

@cncmodeller You are basically looking for a frequency2voltage converter or DA converter.
How many pulses do you get at full speed?

@punktphil looks like that's being introduced in 3.5. You'll find that as features get added to the firmware (at pre beta and beta stages), they'll get documented as it's easier to create the docs when you add features rather than remember to go back and do it.
So for the time being, you can't use K

@alijambo73 M666 is currently only for endstop adjustment on delta machines, though it has been added to the firmware wishlist, I think. Marlin firmware, and maybe others, allows endstop adjustment with M666 on other kinematics.

The work around is to either have an adjustable endstop on one of your Y motors (or both), or to split the Y axis motors into two separate axes, home them at the same time, apply a correcting move to one axis, then set a new axis position. Finally, recombine the axes into one Y axis. Your Y is defined as using drivers 1 and 3, and you have already defined one of them as U (though you don't specify M92, M566, M203 or M201 values for U or V, which you should), so your Y homing would look something like:

; homey.g M584 Y1 U3 P4 ; split Y axis into Y and U G1 H1 Y-1300 U-1300 F1000 ; home Y and U G1 H2 U2 ; adjust U axis (could be Y axis you adjust) G92 U0 ; set U axis position to 0 (this may not be necessary) M584 Y1:3 P3 ; combine Y and U back into Y axis G92 Y0 ; set Y axis position to 0

Well, I think that should work! For a full guide, see the 'Axis levelling using endstops' section here:
https://docs.duet3d.com/User_manual/Connecting_hardware/Z_probe_auto_levelling#axis-levelling-using-endstops
BUT look at the RepRapFirmware 2.x instructions, which split the axis as above. Also note that G1 S1/S2 commands from that guide should be G1 H1/H2 in RepRapFirmware 3.

I'm not sure if following my setup would help, but here goes...

My CNC machine uses the MB6HC control board, and is located in my garden shed. I use an old Microsoft Surface Pro tablet with their keyboard (you can pick these or similar Windows machines up from CEX or similar secondhand retailers) connected to the control board using ethernet cables and powerline adapters. The adapter has three outlets, so I effectively use the adapter as a hub.

I have my main computer (an iMac) in the house, which has a hardwired network, and I connect the Surface Pro and the Duet to that network using the powerline adapter. I also have the facility to turn on/off my CNC machine using a WiFi-controlled power plug.

With this setup, I can use the 27" screen of my iMac to run the design software (Cut2D, at the moment) and access the control board's configuration files using Microsoft Remote Desktop.

Note, I do not run my machine remotely!

Hope this helps, but I'd be happy to provide photos and/or any guidance you may need.

@breed I find CAMBAM works well for me:

https://cambamcnc.com

There’s a decent free evaluation period. If you are only doing small jobs (<1000 lines of gcode) I believe you can continue to use it for free. If you find it suits your needs then it’s not too expensive (£93 one off charge).

I’ve found the documentation clear and the forum helpful.
