Hah, well, I’ve been editing it a lot. And it’s getting a bit unweildy. The more “complete” explanation I give, the longer it gets. Soon, I plan to convert it into a dedicated wiki page with links and such. It should be much easier to navigate and understand.
analysis paralysis or sensory overload… I am seeing crosstalk between an error on ttyACM0 and ttyACM1 home position changing. I posted a video on it here.
Well, that is unfortunate. Got an error that the board I have needs a newer version apparently.
I guess it’s a manual install

Used the Docker install with a rPi distro included with the Pi.
Basic start up was available in a web browser on the Pi. Next up, connect to the Maslow and see what is what
Thanks for the assist

FYI, another firmware update for the M2. I discovered there are 2 versions, and the version of the M2 shield that shipped was not working right. Now, the firmware repository defaults to the M2 shield (and you should reinstall if you have it – with the 3 heatsinks). If you have a shield with just 2 heatsinks instead of 3, this is the V1 shield (and the Github firmware README explains how to activate v1 instead of v2).
The latest version of Makerverse (1.1.1-a) also has a “Reset” button for all the settings in the calibration menu. Plus, there’s a banner that appears (instead of spamming the console) when the calibration cannot compute the positoin.
Thanks for the patience!
On a
Raspberry Pi 3 B+ Rev.1.3 (about the worst device which can handle Makerverse)
(Thanks for the mention 
) tesing with attaching a Arduino Mega (fake_servo), holy firmware 51.27 (is 51.28 the master in the link you posted?) it took some convincing. After a connecting additional power to the Mega and 2 more attempts it worked getting a closer look at the software connected.
The symptoms of the failures were that port and baud correctly set, no connection. Rx and Tx would flicker for a while an the be both on permanently. Not recommending this Pi…
Is there a translation sheet for the $-outputs somewhere?

Is the console output logged? (not watch a bigger test-file on a fake system cut)
The default values for motor height and motor distance looked strange. Took the values from the GC.ini (motoroffsety = 538, motorspacingx = 3501). The default was 68 or something?
In Makerverse, in the Maslow widget, open the Settings pane. See the list of settings. Hover over a setting to get the $number.

I’m pretty confused reading your post, sorry. A few thoughts:
- No settings should have changed if you didn’t flash firmware… they’re all read from your Arduino.
- You said it doesn’t connect, but it looks connected. What makes you say it’s not connected?
It took a few attempts and connecting the Mega with independent power.
Don’t worry, it’s the Mega I use for simulation. Sure I flashed it but when??? It’s holy 51.27, can’t even find where I might have got that. The defaults might be from there.
OK, tried several times to set it up to run at boot per the instructions in ReadMe. I believe I have done everything correctly. I suppose the supplied rPi OS may hvae been off standard a bit.
I can not see/find /bin/makerverse-docker.service. To be sure I had Makerverse running from the command line. I’m ruty and my CL & Linux skills have eroded.
Error noted for
touch /home/pi/.makerverse
docker run --privileged --rm -v /dev:/dev -v /home/pi/.makerverse:/home/node/.makerverse -p 8000:8000 makerverse/core:latest
2020-09-01T22:20:05.842Z - error service:configstore Unable to load data from "/home/node/.makerverse": err=SyntaxError: Unexpected end of JSON input
Looks like I need to have something in that file? I tried the step that opens/copies the configuration and no dice
What other info is needed?
I am going to startMakerverse from the Command line and connect to my Maslow. (I've been working disconnected to get things running)That was removed a while ago. The README has instructions to use bin/service install to install the service automagically. But first, making sure it launches…
Whoops, you don’t need to touch it any more. You can delete that file, then run bin/launch to confirm Makerverse starts correctly. It should automagically copy the default settings now. Then use the above step for making the service work.
I will double check and I did not see/couldn’t start from bin/launch.
Note, this is a docker install, the image supplied was not liked by my rPi. See above
now I have this:
2020-09-01T22:51:55.347Z - error controller:Maslow:ttyacm0 Error opening serial port “/dev/ttyACM0”: [Error: Error: Permission denied, cannot open /dev/ttyACM0]
Verified, no bin/launch found with ls -l -a
As of ~24h ago, bin/launch defaults to using Docker to launch. If you don’t have it, then the code you’ve checked out is old. At least a couple days. Do a git pull and make sure you are on master git status.
That sounds like your Pi user needs access to the USB. Create a file called /etc/udev/rules.d/49-myusb.rules and add:
KERNEL=="ttyACM[0-9]*",MODE="0666"
And then re-plug the device.
got time for some one on one? Looks like I need to learn git. git pull didn’t do anything
either PM here or connect on FB
I may have it. guess work, pulling the repository to local now
Learning new skills
Yeah, Orob left some tips in this thread how to use git. But once you have the bin/launch script, hopefully you never need to update again (it should self-update).
Thanks, slowly working it out.
Learned new stuff today.
I now am up to date with master and doing the build
