The pop-up for the update showed up as my machine was supposed to be homing. I had a large vbit in at the time and it dug into the spoil boards and twisted my gantry. It can't be stopped while the pop-up is there. Might be my excuse for buying better equipment.
The update ready popup only shows up when the machine is Idle - if CONTROL didn't know you were homing, you have some other comms related issue? Homing setup isn't right here either, normal Grbl homing lifts Z up and out of the way first before doing XY moves
So what happened. Homing happens on Grbl, fully unattended. Lifts Z, hits switch, hits switch again but slower. Clears switch, then does XY. Update popup would have no impact on that - as Grbl handles the full homing sequence - if you have an issue like fitting a bit so big you cannot home because there is no space, there can't really be a software fix. Don't click home
Sorry, I was frustrated and typing quickly. I was actually sending it to material home to zero. The pop-up came up, and z just kept going down.
OK, no problem, that's why I ask exactly what - so if there is a bug, we can find how it happens so it can get fixed if it needs to. The presence of the dialog isn't the problem (we want to get you to update so you have the latest bugfixes and features) - the issue is whatever happened that caused you to feel like its an unsafe situation... So new theory, wasn't homing, you were jogging? Continuous or Incremental? Using keyboard, mouse or touchscreen? Or were not jogging, but clicked GOTOZERO? The exact details will help us test and reproduce the issue if there is one
I was using GOTOZERO. The last issue I had was the Z axis wizard doing the math and only getting to 35mm, not 50mm. I will check that again, too.
Gotozero is also unattended, so perhaps you forgot to set zero earlier? Which Z axis wizard was that? And yes, please do check
Z axis looks okay. It was just that one random motion. I used the OB Control Wizard in wizards and tools. I did get a port comm error for the first time while I was checking the axis, but I restarted and it was fine.
Port error, and a runaway move, could be EMI corrupting the serial stream. See docs:blackbox:faq-emi [OpenBuilds Documentation]
Most programs show the update message only at startup and not also during the running of the program. I would not want a update message on a video player, for example, while I'm watching a movie.
Neither do we - it does everything in the background, only if the application is idle does it popup asking you if it can now proceed. You then also have the option to say "not now"
I got my machine back running (well enough for now) and found the issue again. I don't think it's the update because it happened without it. That may have been a coincidence happening just as the update came up. What's happening is, if I use GOTOZERO directly after the "job completed" notice, the z axis dive bombs into the board. I have to move it around first for it to work properly.
my bet is inch/mm confusion, your Gcode ran in inches, but the gotozero runs in mm and is not setting the G21 mode
