I am using an openbuilds ACRO 1010 with lightburn software. Everything has been working flawless till now. Today I went to install a Z axis drive. I have it wired but laying on the bench till I get everything sorted out. I enabled Z axis in the lightburn software. It will follow up/down commands properly from lightburn. How ever, it does not respond to a Homing command, (the other 2 axis are fine) I am running GRBL 1.1f. I have set $132=50 for the stroke of the Z axis. Any thoughts? Lightburn thinks it is a GRBL issue.
Our ACRO grbl has Z homing disabled. Once you install a Z axis, its not an "acro" 2 axis anymore, so install default Grbl again. On the Acro firmware we did this: gnea/grbl for you
Nope, the version you have, already has the changes (thats why Z doesnt home i suspect). To undo it just flash the precompiled, stock, standard Grbl (no compiles needed): from github.com/gnea/grbl/release Or easier: If you are using openBuilds control -> Troubleshooting Tab -> Grbl Flashing Tool -> Select Grbl 1.1f under Default Grbl: NB select the XPRO as controller!
Peter I got it, thank you Reloaded 1.1f, all works great now thank you. Use the open builds control panel to do it.
how can i load the 1.1f file since my machine is a new build, so i downloaded the open control program for the first time. and my z axis will not home at all.
NB the actions can totally wipe bootloader and firmware off your xPro so continue at own risk, not our fault etc. Control > wizards and tools > grbl flashing tool make sure to have a export of your grbl settings as you will have to set them up after upgrading. And note the warning, it can go wrong . Nb nb never use xloader it is not being updated anymore
But a reflash might not be the reason unless you know you had a 2 axes build flashed before... more likely wiring or settings. Use the troubleshooting tab in Control
If you chose Acro as your machine (I assume you did since we are in the laser section of the forum), the z axis is disabled because the standard Acro does not have a z axis. Maybe choose a similar sized machine that uses a z axis.
Selecting an Acro guides you to flash the 2axes build, yes, but the reverse is not the case. So if he knows he did flash the 2axes, use Wizards and Tools to flash a 3axes build (merely selecting machine profile will not flash firmware. Acro being the exception because its so dissimilar to all the other machines)
Nevermind! Got it working. I never use the flash tool. Well I tryied flash tool. Bam it works now. Sorry for the delay. Thank you for each and everyone of you who reached out.
