Probe Basic Errors after successfully probing

I'm not sure how to remedy the errors (also attached).

Invalid params in linear command
 Linear move on line 5 would exceed joint 3's positive limit

This occurs after running a surfacing from the conversational tab. I ran the gcode and stopped it to make adjustments to the positions and then run again. The only remedy seemed to re-probe with 3d touch probe and then reload the cutting tool. This seems excessive and not sure how to fix for the future.

what is your machine setup like regarding tool offsets?

My machine overall is a router style setup with a 30 in x 30 in work area. My spoil board is ~24 in x24 in. The spoil board corner is not at (0,0), well inside the machine soft limits. My tool table only has Z offset and Diameter. After probing the corner of the spoil board, the G54 offsets were: X=5.0161, Y=1.1693, and Z=-7.4953. Z probe Z offset is 2.3607 and cutting tool Z offset was 1.8513. 

i just tried to replicate your warning, but i was able t stop and make adjustments and report without running into any of those error pop up. those are actually linuxcnc statement stating that your entered parameters would cause an over travel event, are you certain the parameters you entered would be tool paths within the constrained machine motion envelope?

It actually happened again last night. Off of a fresh start of Probe Basic, I probed the tool with the tool setter and hit Go to Zero and got the errors. I wasn't able to replicate it again though after clearing the G54 offsets that were previously stored. It's hard to remember what caused the issue when it happens unexpectedly. I'm sure I'm missing something.

Where is your zero home in z

Maybe send as screen shot of your roster settings and probe page settings as well as your z travel.

Also have you edited your var file and added all of the parameter numbers shown in the probe basic docs so the settings are persistent?

Zero is at the top of travel with -6.3 at the bottom.

Attached. I think this is what you were asking for.

Yes, my ini includes a ref to the var file. Settings are persistent across executions of LinuxCNC. Or at least I think so.

ok, i'm a bit confused, maybe something is wrong but mostly what i see looks ok. you said your z range is Z0 to Z-6.3, but i see your earlier post referencing Z=-7.4953 something doesn't seem to be adding up.

is this a bt30 or is30/20 machine with repeatable holders? or is it an er collet type machine?

i'm trying to figure out where the issue is. maybe a detail written walk through r a video would be easier, i don't see anything wrong off the top of my head but without seeing dro's at time of command or active work offsets etc. triggering a limit isn't hard to do. especially if you have an offset set super close to min or max travel etc.

im not getting any of that behavior nor other reports so i have to assume user error, not to be taken as picking on you, just trying to identify where the issue becomes the issue.

if you are suing non repeatable holders, it may be better to use that type of tool touch off. it basically resets the work coordinate system for each tool so it cuts at the same height as the previous tool without storing tool offsets in the table. this tends to work better for er collet type machines and i think there is a really good touchoff routine by another member on here maybe tootall18 from memory? but that is only if you are an er collet. if you have repeatable holders like bt or iso style then the stock touch off is the correct one to use.
