    I am currently testing out a new build. I have milled out several test projects and I have made a few mistakes but who hasn’t. I have a V8 board and .10 FW loaded and I am trying to get an NC file to do the probing. I am using JCNC at the moment which has very little support out side of sending Gcode. if I use coolterm to send the following codes waiting for the probe to finish it works but when sent via a NC file it probes but nothing else. this probes, sets z to my puck height and backs off 10mm.

    G38.2 Z-10 F20
    G92 Z19.84
    G01 Z10 F200

    Here is the output from coolterm when trying all 3 command with a cut/paste

    I have a V8 board and .10 FW loaded and I am trying to get an NC file to do the probing. I am using JCNC at the moment which has very little support out side of sending Gcode.

    There is no 0.10FW (that I am aware of), as of today the tinyG Master build is 440.16.
    Please report value of parameter $fb

    The last time I tried JCNC with fw build 440.14 I got nothing, I assumed JCNC no longer worked, so I am surprised you are getting anything. Perhaps that was an issue on my system

    It would help deciphering the CoolTerm dump if you turned on “local echo” so that the commands you enter would show up in the dump.

    PS
    Misteaks? Not me, that is just a pile of scrap lumber over in the corner, all cut into little pieces.

    the commands are the three listed above the stuff the tinyg outputted, I just separated them out to show what I had sent. like I said works in coolterm when you wait for the probe to finish, just note all at once. I have tried may applications, I want to be disconnected from the net so pepper isn’t an option. grblgru has promise but the front in is needing work.

    OK, gotcha I guess. All that output is for the probe, first line of Gcode.
    I need to read up on G38.2, don’t have time at the moment.

    Please respond with your FW version, in case we are chasing a defective G38.2 command implementation.

    Likely contributing, you need to get to fw 440.16.
    G38.2 was very young way back then.

    Give it a try, if it fails for you, check this thread tomorrow AM

    Reminder: you will have to reenter all your parameters. Make a copy of what you have. 440.16 will likely introduce a couple new parameters.

    well that was a p.i.t.a to do, but got it done. I am better off than some, I have played with several ardurino’s and PI’s so doing the avrdude didn’t scare me. hade to follow the manual way to install 440.16, got verify failed when doing it the updater way. got my cnc back up an running. jcnc still doesn’t allow me to send all 3 commands at once ,but I can now send all 3 via coolterm, so I would say the problem is with jcnc. thanks for the info on loading the FW.

    Yes is is a pain, but you are clearly ahead of most who wonder who this dude avr is anyway.
    Good luck with your project
