little jogging problems #118
Comments
Hi Stefan, does the buffer meter (green progress bar in the machine tab) show something other than zero when this happens? In that case, try clearing the buffer (click the progress bar) and if that doesn't help, soft reset the machine. Apart from the G92 work offset, you won't loose the machine position. This happens to me sometimes as well, though only very infrequently. Cheers, |
Hi Martin, yes the green progress bar show any number other than zero. By click the progress bar nothing happens. Cheers Stefan |
Hi Stefan, ok, that's strange. I usually get it to work again after a bit of fiddling...
this is interesting... Can you send me a link to your firmware (as long as it runs on a blue pill)? I don't know when I'll have time for debugging, but I'll try to look into it when I can. Is this a show stopper for you or can you work around it for the time being? As for G93-95: I never used it and since I don't know of any post processors which can't be made to output pure G93 code, I don't see the need to implement this. Cheers! |
Hi Martin, sorry, my mistake, something went wrong earlier, of course your program accepts g-code and jogging commands like G0/G1 and $J=G91... |
I'm afraid I don't think I do, can you try to explain it in German maybe? Cheers |
Hi Martin, sorry für die späte Antwort. Also dann versuche ich mal das ganze in deutsch zu erklären. ;) Bezieht sich alles nur auf meine Steuerung mit dem STM32 (BluePill) ist also vielleicht nicht aussagekräftig bei anderen Steuerungen. Hoffe war nun verständlicher :) Gruß |
Hallo Stefan, ok, das ist wirklich merkwürdig... Eigentlich sollte der Pufferstand niemals negativ werden können. Vermutlich hat es etwas mit der grbl-Version zu tun. Ich verwende bei mir den Port von https://github.com/usbcnc/grbl, der hatte allerdings in der Version im verlinkten Repo auch noch Probleme mit der USB-Verbindung (Ist in einem der Issues beschrieben). Wenn sonst nichts hilft, kannst du den mal probieren. Grüße |
Hallo Martin, Grüße |
Hallo Stefan, Ein Readout für die A-Achse hatte ich sogar mal in OpenCNCPilot eingebaut: #63 (comment) Ich frage mich bloß warum der Branch nicht mehr existiert. Ansonsten kenne ich nicht viele GRBL-GUIs, da musst du dich ein bisschen umschauen ;D Grüße Edit: nevermind, laut einem anderen Kommentar von mir hat dieser Release auch kein Readout, sondern ignoriert nur den entsprechenden Eintrag in den Statusnachrichten. |
Hello Martin,
actually it is not a real problem with your program but maybe you can help me anyway.
I use an STM32 Blue Pill to control my 4 axis milling machine which also works wonderfully.
Depending on the milled part, I use GRBL Panel or your program OCP as a g-code sender.
Now to my problem, when I move the machine in jog mode, GRBL sometimes no longer accepts jog commands.
Assume it is due to the STM32 and the GRBL implementation. Unfortunately, everything works fine with the original
Arduino but no 4 axes.
In GRBL Panel I can briefly press one of the arrow keys, then the jogging works again perfectly.
Unfortunately, there are no such control buttons in your program to reactivate jogging.
Maybe you can give me a tip on how I can reactivate jogging in your program?
Greetings Stefan
