Hmm.. no, there should be a few messages if everything is good and some errors if it's not. I think something is amiss with your config.

Can you try a basic config generated by the config tool?

Ok so a generated Config file seems to work.
Hmmm - I will start modifying it slowly to see what broke it.

If everything executes cleanly you should get something like
M98 PCONFIG.G
HTTP is enabled on port 80
FTP is disabled
TELNET is disabled
Warning: Heater 1 appears to be over-powered. If left on at full power, its temperature is predicted to reach 893C.
Well, actually, looking at your config it looks like you may not have any of the network commands and your heaters may not be overpowered.

With the generated config file it also does not print anything to the console.

And for good measure can you post the results of M122 as well when configured as E?

We could also start sending the basic axis setup commands by themselves to see what the firmware thinks is configured and see if it meets expectation.

M201, M203, M566, M584, etc etc

But I think we may get good results from a clean config.

That may be normal. In SBC mode there aren't any network commands present to echo back, and your heaters may not be over powered so no warning.

Can you post the generated config?

If you're trying to get percentages with this, just use M913 instead. I set my current to the rated max with M906 and then use M913 to set it to a percentage of that.

I found the culprit:
M906 E900 ; Works
and
M906 E{1000*0.9} ; Gives the issue.

Interesting that these seem to work:
M906 X{20000.8}
M906 Y{20000.8}
M906 Z{2000*0.8}

One more note:

MikeGeppert

Thanks so much for the help!

The original Config file now works with the one change:

M906 X{20000.8}
M906 Y{20000.8}
M906 Z{20000.8}
; M906 E{10000.9} ; This seems to not work
M906 E900
;M906 U{1000*0.9}

My homing macros try and set stealthchop and sensorless homing. To do that I have to cut the current to 30% using the M913 command. So if I cut to 80% at first in the config file, do I then cut to 80% * 30%? Then set back to 80% when done?

This is exactly why I leave M906 as the full rated current and then adjust with M913. That way I know that M913 80 is 80% of rated. And 30% is 30% of rated. It's just more direct. No percentage of a percentage.

Mathematically I want the 80%*30%. My intention was that once Variables get implemented I would make a MAX_MOTOR_LDO that has the 2000mA value. And another variable that would have the percentage MAX_RUN_PERCENT to be like 80%. Then set the M906 to the multiplication of the two. Then I can use percentages of that MAX_RUN_VALUE.

Seems needless when M913 already exists, but it would work either way.
