I want to live in that room, it's so clean! Awesome Build @Dina Jacobson Thank you for sharing
I'm still working on my labview project, having trouble moving machine with VISA resource.
It has status respond but won't Gcode move Is there termination characters to set in settings?
Shouldn't be any termination characters for single-block serial G-code streaming. What's the return message when you send G-code lines?
You can terminate your gcode strings with a newline ("\n") just for sanity
Have you tested that you can move it from a known working host like OpenBuilds CONTROL - just to make sure you have the Wiring and Stepper Enable settings ($4=1 Invert Enabled needed for BlackBox as set by our default profiles) set correctly
Everything works awesome with openbuilds control and running meter manually.
I am a labview newbie, I get a <Alarm|MPos:0.000,0.000,0.000|FS:0,0|Pn:XYZ> error when connecting with VISA control.
I am using CNC Machine Control Interface (SARA WILLNER-GIWERC, Grbl 1.1 (Benoit Seguin), and manually adding my visa resources. The CNC machine control interface is the one giving me error feedback.
On reboot/connection, if you have Homing enabled, Grbl enters ALARM lock to force you to remember to Home (or manually Unlock if you are happy to handle the consequences of not homing). Send a "$X" after connecting to Unlock it, or add a Homing button ("$H") to let the operator home the machine. Both will clear the boot alarm.
See Grbl v1.1 Interface · gnea/grbl Wiki > "[MSG:'$H'|'$X' to unlock]" section and also see Grbl v1.1 Commands · gnea/grbl Wiki
I tried that, doesn't clear the <Alarm|MPos:0.000,0.000,0.000|FS:0,0|Pn:XYZ> from scrolling in the read buffer box.
Now in openbuilds control, it has failed to clear limit switch when pulling off, and jog says will hit sof-limit.
I have to go check the machine
Ok good, so its not the startup alarm, its an actual alarm. Will need to resolve the cause of the alarm before you can Unlock
Soft-limits error is a symptom of the Failed homing cycle (Homing sequence did not complete because of the Could not clear limit switch alarm, and thus does not have Machine Coordinates established, and that leads to the symptom where Soft Limits prevents jogging, because it doesn't know where the Machine Coordinates are yet)
Check your Homing Pull off setting is sufficient to clear the switches, otherwise it may be a faulty switch or wiring
some of my settings got changed (I have to find where) main setting
$4 invert step enable pin was set to disable S/B enable was the one preventing
unlock. I have to get all my other inverts and stepping set back up again before
I try thru labview. I'll let you know how it goes.
Thank you for your help
It works with the machine control program
