Additional or extended settings masks

I've use bitmask values for parameters with Centroid CNC12, but I'm not sure how they are used with OB Control/GRBL. For example, I'm looking at some of the $22=<mask> options here. Are they set with only one bit choice, or are they added up.

On a related note, if homing is required at restart or other situations, should there not be a "in your face" warning that machine home has not been set, or perhaps I need bit2 applied along with another bit. The only thing I've seen is a small message at the bottom saying that it can't move in that direction. It would be nice, if the machine is not homed, that you could jog towards the machine home and then issue a home all once close. No other operations would be allowed until homed. I've made a "Park" macro that is to be used before shutting down for the day that positions the axes close to home for quicker homing, but that only works if you use it.

Thanks,
Scott

 

Thanks. I did try some, but it seems that only 0 or 1 really work. Other values may set $22 blank and disable soft limits. Setting soft limits back on and then $22 back to 1 throws an error and you have to do soft limits first and then come back and set $22 to 1.

Not being sure how bit0 (in the attached list) is counted, I tried 7 and that puts it in an error #46 undefined loop. I did however get the desired "Homing required" warning pop up for a split second before getting in an endless error loop. What I'd like would be bits 0-3 and possibly 7.

This is with OpenBuilds Control, and from what I see, it seems like with $22=1, bit0,1, and 3 definitions are in play, but there's never any kind of warning for homing required (bit2), even with $65=1 set. It seems like there is some kind of settings overlap with $22 bit2 and $65.

The part that I'm missing is just a simple "Homing Required" warning, so the customer/user knows what he needs to do first upon start up or any other situation that requires a rehome.

$22=<mask>
Changed from original boolean to exclusive bitmask for enabling homing and homing features.

bit0 - enable homing. Only when this bit is set can the other bits be set.
bit1 - enable single axis homing commands.
bit2 - homing on startup required.
bit3 - set machine origin to 0.
bit4 - two switches shares one input pin.
bit5 - allow manual homing of axes not automatically homed.
bit6 - override locks, allow reset to clear homing on startup required alarm.
bit7 - keep homed status on reset if possible.

 

Thanks for that reference. Found it with $help settings also. I've tried all combinations and it appears that 0 or 1 are the only ones that work. Anything else puts it in an error 46 loop as soon as the alarm is clicked off, and then task manager/end task on OB is needed. Am I missing something else to enable the mask settings for $22? My settings inserted.

Side note, once $help settings is issued, you can no longer get to the GRBL settings page, and quitting/restarting is required to get back. ?

Thanks. Any thoughts on the "error 46 unknown" issue when applying anything other than 0 or 1 for $22 additional/extended settings in OB Control? I'd really like to get the homing warning working before handing this machine off to the customer. I do get the warning message dialog/window with $22=5 or 7, but as soon as you hit unlock, the error 46 comes up and hitting OK just keeps looping the error. End task is then required.

This is with OB Control and a BlackBox X32.

I tried both of those values. No warning, but you can unlock it. Home All button is disabled then, but you can home with $H.

If I go from $22=1 to $22=5, I will then get the Alarm 11 Homing Required. If I hit Clear, then I get the Error 46. If I hit Cancel, Home All is disabled, and sending $H works, but Home All stays disabled. Upon the next restart, no warning, and clearing the alarm goes into the Error 46 loop.

Not sure how to extract logs, other than a copy/paste, but can't do that when the error happens. Are they saved somewhere? Look at the usual places in windows, but none looked to be useful.

This issue and Z probing are kicking my butt. Finally got probing to work (sort of) after finally finding some info on needing to flash the firmware manually, but It still doesn't seem to work right. It doesn't do the search part of the probe, just seeks (slow seek rate) and touches once instead of twice. ? I've searched so much for answers on this little thing it's ridiculous!

 

Because it's a custom machine (rebuilt old Probotix Fireball V90 ), so that's what I started with.

I just figured that since I'd seen posts, while searching for homing options, mentioning the Additional/Extended settings for $22, and that they were available to use in the machine config, that I'd try them. A note that they weren't compatible with Control would have been helpful and saved much time.

1) Didn't know that firmware needed to be updated manually. Finally found that out after searching for probe issues, where the probe routine just stopped at the touch plate and failed.
2) Did that.
3)Limits are installed at max axes, don't have or need hard limits (using soft limits). Again, since Additional/Extended were shown as available with $help settings, I wanted to try to get a homing required message on screen for the user.
4) Did that.

After finally finding some reference to the issue, I did do that, and it started working. It would be nice to have a "Sticky" post in the OB Control software thread that has setup and use documentation covering these kind of things all in one place, so one doesn't have to search through many unrelated searches. Just for reference, here's a good example of that from the Centroid forum.

One last question about Z probing with the wizard. I assumed that it used the settings for the toolchange parameters of locate rate, search rate, and pull off rate, and because of those, it would do a double touch probe (fast then slow). Apparently it only probes the Z once and the probe rate and distance are hard coded at 100/-25. Is that correct? Here's the terminal from the probing routine showing .



So, I'll be leaving $22=1, single tap Z probing, and handing the little rebuilt machine off to the user. I do like the little BlackBox X32 system though for these smaller machines, and might consider one for myself sometime for a small build, but the reset/homing options need to be in place. Cool little, affordable kit with a lot of stuff packed into a small package with great potential!

Thanks for the help,
Scott
