@dc42 Let me know if you need anything from me. I realize I am probably apart a small few experiencing this issue.

@chrishamm Changing AJAX to 5 seems to have worked.

@stuartofmt I am not familiar with what you are referring? Do you have a link?

just google "biqu hermit crab"

As I have been looking into this more, it may be related to a specific print file. I never had this problem before. However, a specific print had some GCode that specified the hot-end change temps for extruder 1 (T1) at the time of tool change. This was actually a problem as it was setting my "cooldown" temps to the active extruder, but it immediately set the working temp after. When it would pause and then I hit resume it would sometimes show the correct working temps, but other times not.
I manually went through the GCode to fix this problem rather than re-slicing and uploaded to the Duet. It ran through the entire print without a hitch. Once I get enough of the parts pushed out I will attempt to go back to the unmodified GCode and see if it actually had anything to do with the G10 codes occurring in succession or if the code was just messed up. OR look for Gremlins...

The GCode I removed throughout the file was as follows:

G10 P0 S210 G10 P0 S240

and

G10 P1 S210 G10 P1 S245

@fcwilt

Thank you for your help up until now. I'll continue to do some testing later this week to see if this is motor-related.

I got my Lead Screws from ZYLTech a few years ago. Never thought to look at McMaster. I suspect if there were variations I should see those in my layer lines, which I don't normally have an issue with since upgrading to these. However the anti-backlash nuts are brass and could have some play. I do my best to keep them greased.

I am thinking there may be some play in my Tool Carrier. I know that I can get flex up to 0.14mm when I put some pressure on it, but it does want to return back to 0. Today looking into this further I dove the tool into the bed and found it didn't want to return to its normal height. So I docked and undocked it and picked it up again, the tool height was back to normal. I'm suspecting that it's shifting in the kinematics and even though it's a ball bearing and has no scoring it's not able to return. This would not explain the BLTouch variation, but maybe a factor when it comes to printing.

@owend

I'm thinking I need to do something like that but seems like this used to work. I guess maybe I didn't miss something!?

Thank you for the tip!

I'm not saying there is anything wrong with the release. Just noting what I had to go through to get things working. Its my belief that removing the additional firmware (which would be for your board) is what resolved my problem, though it could have just been the final upgrade to the v3 RC12.

As a side note, I'm still not getting "filaments" to work. The config.g for those doesn't execute. Though they did before all my recent updates... 😢 have to rely on my slicer for most things still.

@Gamefanatic3D Thanks for your feedback!

I just went ahead and updated to 3.0 (2020-01-03b3) and everything is working so far. Probably just a bug or bad update, because it was working before and after the 2.05.1 update.

you dont need excessive tension but the belt tension will effect the squareness of the gantry. on my corexy I need to set the one motor/belt to be noticeably tighter in order to get square prints out of my printer. Equal tightness does not mean a Square gantry. needs to be adjusted and checked for squareness

I changed the Z limit to 0.05 and everything is working great! It's always the simplest things we overlook. Thank you for your help.

I upgraded to the v2.04 firmware with the new web control. Still getting used to it. I kind of liked the old interface where I could watch my job stats, control most interface items and still watch my web cam at the same time.

is that really worth the hassle? just get a thermistor where you can get the temperature table.
like an ATC Semitec 104GT-2

Just a FWIW. I traced the circuit out a bit further down, to R75 on the board. With the SDCard ejected I get no resistance. With the card inserted I get resistance. I'm assuming that directly relates to the CD as it closely matches the resistance when I measure directly to the ground PIN.
