Much clearer, but the first sentence still says "bed compensation should be tapered off over the specified height." I think what throws me is the word "height" - I think "range" would convey it better. One last suggestion and then I promise I'll shut-up and stop wasting your time!

This command allows the bed compensation to linearly taper off over the range between Z=0 and Z=H, so that full bed compensation is applied at Z=0 and no bed compensation is applied when Z is at or above H. If H is zero or negative, tapering is disabled so compensation is performed throughout the entire print.

I used to manage a group of engineers who had to do a fair amount of technical writing. I'm pretty sure they hated me (at least when they were writing datasheets).

Excellent, thanks!

I'm sure this has been asked before, probably more than once, but I couldn't find it and the CoreXY wiki page still uses M667 S1. I'd like to upgrade from 2.01 but want to make sure I've got this right before I do. Thanks

Thanks - I'll try that the next time it happens.

@dc42 Nope - I don't even know how to upload files to the Duet without DWC.

@dc42 I don't think I had multiple http connections (though why should that be a problem - isn't one of the advantages of web-based control that I can run it on my PC and then check the print remotely on my phone?), but I initially had the USB serial port connected.

I had literally just powered up the Duet. I guess it's possible that I left a web browser open to my Duet's page somewhere from the last time I used it (about a week before this) - would that cause a problem?

@dc42 My Z sensor has more variation than my bed, so I just do a 4 point to make sure the 4 corners aren't out of whack and then I print with no bed compensation. That part's all working fine.

The problem is the non-stop repeated messages. There's no way to stop them or acknowledge them and stop them. And it's not just bed levelling - earlier this month it was a heater fault (messages continued after fault was cleared). I've had this problem with various messages ever since I started using the Duet ~2 years ago. As long as the Duet doesn't send me an error message (which is fortunately 99% of the time) there's no problem. But I thought after a few years I should figure out root cause and make it stop.

Thanks

I mentioned a specific instance of this problem a month ago. But I've had it off and on for the two years or so I've had a Duet. I just powered up my printer for the first time in a week, homed the axis, performed a 5 point bed compensation, and now I'm getting a constant stream of " Warning: Triangle interpolation: point outside all triangles!". I can't stop it. I reload the DWC web page and it keeps going.

I know it will stop if I reset the printer, but then I have to home and level again.

Is there a way to make it stop happening, or at least stop it when it does happen?

@garyd9 That's very interesting and I do have the garbage at the end of my S3D-generated gcode.

Downloaded S3D 4.0.1 and verified that all three print time estimates are working again. Thanks!

Update: I put a new thermistor in and have printed for ~14 hours with no faults and no glitches caught on the graph. So the problem was probably the thermistor.

I did test the bad thermistor afterwards with a DMM. Couldn't find any leakage to the case, and tapping it didn't produce any visible shifts (DMM, not a scope, so hardly comprehensive). But I'm satisfied. Thanks for the support!

I actually noticed the same thing, but with Simplify3D. It used to work, and I don't think I changed any relevant settings in S3D, but layer and filament have stopped working, somewhere between firmwares 1.2x and 2.x.
