Hello all, I'm fairly new to GRBL and am currently running v1.1f. I'm trying to read the state of my limit switches as well as any other pin states. I've tried setting $10 from 1 to 3, but still only get the same status with the "?" command. Here's what is being returned: <Idle|MPos:0.000,0.000,0.000|Bf:15,128|FS:0,0|Ov:100,100,100> I occasionally get: <Idle|MPos:0.000,0.000,0.000|Bf:15,128|FS:0,0|WCO:0.000,0.000,0.000> I've also tried issuing the ? command from both Candle and via a terminal emulator like Tera Term. I ultimately want to be able to query a spare pin (or repurposed one) for another function. Any help would be much appreciated! MotoDan
Thanks for your reply Peter. I’ve seen the wiki and a bit more, but am not able to get the reply that is expected.
Does it matter if I don't have anything connected to my GRBL board? My ? Status report is just not showing any pin or limit switch info.
OK, I finally figured out that I had to have something connected to any pin inputs in order for them to initially be seen via the '?' Status command. Thanks!
