@matth: The fix is baked in to .87

I tested it three times, and that seems to fix the issue.
Oh good. I was waiting for my current print to finish before using that command. I've tested it with several difference gcodes and got similar bad results. I first noticed it after printing:
Nevermind. I am able to reproduce it.
Can you send me the GCODE from a print that is exhibiting the problem?
@matth: I suspect it's the bed leveling that remains enabled after a print. Can you run "M420 S0" from the console after the first print and see if it restores your ability to calibrate? If it does, it would be an easy fix for me to do that prior to the auto-calibration.

Confirmed this is now working as expected.

Versions up to .80 had a workaround for a Marlin bug. In .81 this workaround was removed as it seems like the underlying issue was solved by the MINIMUM_STEPPER_PULSE

I checked a few of the Taz 6's over here and a couple of them seem to be a bit off. We've got one that says it's been used for 20 hours, which seems a bit low for our printers over here, and then another one that says around 2 days of print time on it, which also seems a bit low. We have another one that shows 13 days of usage, which seems a bit more in range.

Testing on SL 22.214.171.124 i am unable to set the fan below 0% are roll it over above 100%
Seems fine to me. I powered off, moved the toolhead to different positions, then powered on. Each time the toolhead just moved up to the top most position.
LCD calibration is working fine with USB flash drive plugged in from the start and halfway through calibration.
@karrad: I would never trust an odometer, on a printer or on a car. Supposedly on newer cars it is extremely easy to hack using an inexpensive tool from eBay...
Plugging in USB drive while in calibration screen also did not kick back to main menu. I was able to complete calibration as expected
@bigmansas Before sending out the info, please check a few of your printers around TSR to see if any others have become corrupt. Marlin doesn't document that command to try to keep sellers of used printers honest: http://marlinfw.org/docs/gcode/M078.html
however, now there appears to be a bug where when at 0 the user is able to decrease speeds past 0 and loops back to 100. It appears to only be the lower limit.
The counter probably got corrupt. The only fix is to have the user run "M78 S78" which resets all the statistics to zero (essentially rolls back the odometer!)
Testing on SL 126.96.36.199 with USB plugged in I am able to calibrate.
@tutley: This would be tricky to do, plus homing at startup helps level the X-axis, so there is a reason to do it.
@jebba: If you are satisfied with the behavior in .78 or .79, please close this ticket.
@youngmrcarlson: This has been addressed in .78. Please confirm.
This will be addressed in .79

@bigmansas Hmm, I would suspect that total print time is off....

@oliver: I see. What happens is that if the USB thumb-drive is plugged in, it jumps to the main screen to show that the drive was inserted, this will typically happen before the calibration screen has completed.
@tutley Could be, this is something we can do a final confirmation on beta units than.
@oliver i also have the USB plugged in and i am not seeing this. however my unit has all the upgrades for EMI/ESD. Maybe this is why i am not seeing this
I can confirm that I am still seeing this issue on my printer running FW .78 when the usb is plugged into the printer
i am not having any issues with calibration on .78
I can also confirm that this is the case with mine as well. Currently running FW 188.8.131.52.
@oliver Thanks for mentioning that! I discovered that the issue exists when the USB flash drive is plugged in. If I unplug it, I'm able to calibrate.

@oliver: That makes sense. If the board is not present, it will try to show an error message and this would cause it to jump to the status screen, even if the calibration screen was up.
@marcio The USB board
@oliver: You mean with the USB board not plugged in, correct? Or with a USB flash drive not plugged in?
@marcio After creating the fixture to test the touch screens I did notice that without the usb plugged in, when trying to calibrate the screen it will go grey for a second and quickly snap right to the main screen. My guess is it could be the marlin interrupting the screen calibration to display some error message.
@youngmrcarlson: I am unable to reproduce this. The calibration screen will only show up if the touch screen is detecting a touch at startup. It looks like your touch screen may be registering invalid touches -- possibly something is causing those false touches?

I have confirmed this on my printer as well.
Nevermind, can recreate this on Q11. That text is a good distance away from the button being triggered.
@youngmrcarlson I'm currently unable to calibrate the LCD. The calibration screen shows for a quick second, but exits to the main menu before I have a chance to tap dots.
Did you try re-calibrating the touch screen?
That is done by powering off and holding a finger on the screen while powering on, this will trigger the calibration sequence prompting you to touch several points. You may try using a dull stylus of sorts to increase accuracy.
