Woops. I should have provided more information. What happened is Ground Control had a parameter value, KpPosZ that differs from the Firmware value. In GC, the value was 1300; but in the Firmware, the value was 0. It is asking you which value to use: the one from the Firmware, or the one from GC.

KpPosZ is something i would never touch as far as i recall never changed, so if uncertain choose FW?

I have had the same experience with this and other parameters. I don’t know what the value should be, what the source is, or why they are different. This may be a good wiki topic.

I had no idea we are paddling in the same boat 
, makes it more enjoyable
KpPosZ should be 1300. I only know this since I have lots of copies of ini files for “bad” and “good” states.

I like this! I do also have them and a few have actual calendar dates. The rest i still can sort by date changed and have a history. Keep em

Unless you are hooking a new instance of GC (or an instance where you have made
questionable changes to your .ini file manually) up to a working and calibrated
machine, you should probably have the version from GC (the .ini) version
override what’s in the firmware
since GC cannot know why they are different, and there are the scenarios where
you have reason to think that the numbers in GC may be wrong, and want to use
the firmware version, we have to ask, but I think that for most people the
correct answer will be to use the version from GC (and if it makes the machine
less accurate, you re-calibrate)
does the log show the old value so if this makes things worse, the person can
look in the log for the old value and try that?

Can you get a new calibration from these versions? All that was written above is very difficult. Our machine is not calibrated its error in 2mm in height, and the line is not always smooth. Does this calibration help solve the issue?
1 Like
Yeah. It has only been tested by a few people, but it should be functional in its current state.
I believe this calibration will result in a more accurate machine than this. There are several potential causes of a non-smooth cut; specifically, there is an issue in the main fork which prevents parameter values from correctly getting to the Firmware. This issue may be corrected by these updates.
I just tried the holey triangular GC and it errors out when I try to load a file or set the PWM frequency with a similar error (only showing the tail end of the error)

This isn’t very helpful. Everything shown is just related to where it happened within the kivy framework. I would be more helpful if you send the whole error stack.
Which file? Are you talking about loading a *.nc file?

Ok, when I get back out to the hackerspace, I’ll post the full error message
Which file? Are you talking about loading a *.nc file?
yes, when I try to load the six hole calibration g-code
I also discovered that if I went to change a config item and left it blank
instead of entering a number, GC crashes (and crashes again at startup) with an
error that it cannot convert a string to a number.
I was hoping that if I left it blank, it would reset to the default.

Hmm. I wonder if something is wrong with the *.nc file. I can check this on my machine.
This is pretty good information. There might need to be a check for an empty value. I will look at it.

no, I looked at the file and was able to load it into webcontrol
I got what looked at a glance the same error when I tried to change the PWM
frequency.

or check for a conversion failure and put in the default (and/or re-prompt the
user) rather than just checking for an empty value.

I am wondering if this is related to a change I committed on Sunday. I ran into an issue importing from the MaslowSetings.py module from firmwareKeySyncPopup.py. Was the version you are using downloaded before Sunday?
no, this was pulled tuesday night.
David Lang
Last night, I was able to open Ground Control, load several *.nc files, and set a few of the parameters to empty, without any issue.
Could you send the full error-stack that is reported?
Thanks,
