So I am attempting to run a 20 watt Comgrow diode head on a LEAD 1010. The setup is a little weird to me. I have the profile configured with WiFI enabled on X32. First of all, I may be mis-understanding something, but the *only* time when WiFi connection from Light Burn to X32 works is when OpenBuildsCONTROL is running on the computer and actually connected to the X32 via USB. Without active connection there, LightBurn wont connect to WiFi . I was under the impression that once profile is loaded onto X32, there is no longer a need to computer connection and Light Burn would be able to take it from there. The main problem though is that I literally spent 2 days trying to figure out the coordinates. Check out the attached screenshot. Once the laser connects, the homing process properly detects my desired origin and parks the head front left. Exactly there I want it as I have it set as Origin in Device Settings screen, that is what my Job Origin set to on the laser control panel, and that is where the head is parked and Home position indicator is on. And coordinates on the work area agree with me. But if you look at at the top, pressing Get Position gives you those wild coordinates telling you the head is currently is the far right corner. Placing a design at the lower left corner of the work area and pressing "Play" button makes the head go to the far right corner. So does the pressing "Go to Origin" button, even after pressing "Set Origin" while the head is where it supposed to be. It does not seem to be inverted either, because when I place a design in any location on the bed, and playing with Job Origin location, places the green dot exactly there it supposed to be. I've tried resetting the laser profile, restarting everything, changing settings to go in reverse, read every ******* post on the internet and watched every video. I can not make it behave for the life of me. What am I missing here???
Before we get into the intricacies of Lightburn, make sure everything works in CONTROL first. Much easier to a) figure out and b) for us to help with. Basic shakedown: 1) Does machine MOVE correctly (Jogging X+ moves head toward right of stock, Y+ moves head to back edge of stock, Z+ lift head up and away from stock - ie all + moves goes to axis maximas - If not, correct $3 Direction invert 2) Once thats all correct, use $23 to tell Grbl "where are the homing switches" - its not used to invert directions, its to tell Grbl - hey you expect switches at axis maximas by default, any axis where you have it on the opposite side, needs invertion Homing direction. CONTROL makes this a lot easier, the switches clearly shows MIN/MAX just tell as where you have the switches installed on the actual machine 3) Origin is set using SetZero buttons or a Probe - simpler to understand too. Work Coordinates (origin) are seperate from Machine Coordinates (home). But Work Coordinates are but an offset from Machine Coordinates, so always HOME before setting any Work Coordinates (Zeroing) FInish that up first - when it all works perfectly in CONTROL, then you can try Lightburn again As for Wifi, not sure how Lightburn handles it, but in essence grblHAL should only be managed through endpoint (never usb and wifi together. One at a time between USB, Telnet or WebUI, never 2/3 at the same time) The "wifi" connection is just Telnet - otherwise exact same as the serial data stream over USB
All of that works as expected for XY. Z is reversed so Z+ moves it up and Z- moves it down. All of that is also according to expectations. I have the probe but so far i was able to get away with a simple sheet of paper method to set the bits and it hasn't failed me yet. As far as the reasons to use WiFi, its my experience with Lightburn. I used to have a cheap little grbl-based Comgrow Z1 laser engraver and wasted way too much time on connection drops, inability to connect, constant computer restarts, etc. On Windows, Linux and Mac. I haven't had much luck with Lightburn and X32 either. Constant "Busy" messages and hangs. The benefit of having Control running over USB and Lightburn over wifi, is because when Lighburn starts homing in the wrong direction there is no stopping it, if you dont stop it, it will just hit the and keep trying tio move it . Switching to CONTROL window and hitting Abort button stops it immediately
Then the rest of the Lightburn specific bugs/issues can be taken over to Contact / Suggestions Just making sure, you have updated Lightburn to the very latest? Still not agreeing with multiple connections through, suprised it almost works, but might be cause of the Lightburn BUSY issue etc. Really should only connect over one endpoint at a time
Interesting. I just realized that all this backwards movement is only happening when I load profile with limit switches enabled. Without them, machine does not go into the negative space.

And this is exactly where I have the problem. With limit switches enabled and $23 = X min, Y min, homing works fine, however, Home coordinates and up being: I assume it is because I have these set So, at this point, even if I click "Set Zero", moving in any direction produces this error And If I set $23 X = max, and Y = max, homing sends the head to the far right corner, exactly what I am trying to avoid.
That's the WORK Coordinates Remember to probe/setzero to set those 1) You are running standard Grbl (no 3rd party version, custom compile?) - if yes, flash back standard firmware first. 2) Soft Limits needs just two things: 2.1) Axis directions / Homing directions set correctly (everything must follow cartesian standard) You had something backwards, could play into this and 2.2) Remember to HOME first (Soft limits applies to machine coordinates) Have a read through Negative Coord System: Frequently Asked Questions and Soft Limits Grbl v1.1 Configuration (PS Soft Limits alternative, install Switches: docs:blackbox-x32:connect-xtension-limit [OpenBuilds Documentation] (2nd diagram for min/max)
