That is a great point! That is way off!
Wouldn’t recommend it, but if you do be ready to pull belts out and/or power off in a hurry. It does weird things when you use the wrong setting. Not that its not doing weird things now!
No need to take things apart just yet. Those two tests can be run without needing to disassemble anything.
Ok so when I get back to it tomorrow what do you guys want me to do first and what to report back.

I think that the things to do are:
#1)
This one is super fast and easy so why not start there
#2)
I think that this is potentially a PHENOMENAL insight from @ian_ab. That number is way way off and it is the top left belt which seems to be behaving strangely. Let’s reduce that number (tlx) to zero and then try again:

So this morning I save a log when I hit the test button after I powered everything up. I then changed the value in the configuration for tlx to zero. Saved closed everything out, powered down and brought everything back up. Then retracted,extended and retracted. Hung it and hit calibration. It went from the bottom to off the board diagonally ish. I broke down and disassembled the arms,lubed and checked them out (due to the high retraction needed) helped somewhat. Did the dance again but put the value I changed to zero back to where it was and the machine went to the middle and faulted out with the red light. Too far off center I think it said. It when on the attached logs. Now does this each time.

Darn so basically exactly the same as before 
Tell me more about this, I think this might be important. Did you set the tlx value back to what it was before or did the machine do it automatically?
I am going to DM you a code for a new controller board. I’m 99% sure that there is nothing wrong with yours physically, but a fresh board will give us a 100% fresh software install.
Hopefully we’ll be able to figure out what is going on before it arrives, but better to have it on the way and not need it than to wait later.
Thank you. I’ll get it ordered asap. Hanks for all the help troubleshooting. I really am excited to get this up and cutting.

Ok. So I changed the value back from zero to 139.2 I think it was. I did it the machine did not. Did the on/off retract/extend thing. Hung the machine and hit calibration. My machine was just about dead center of the spoil board and the bottom belts slack when I hit calibration. The machine pulled the slack out of the bottom belts then the top (really no slack to take there) so the machine was in just about the same spot I hung it in now with tight belts but got the flashing alarm light about my center being off and the system not able to compute my frame size. Now each time I do what I call it the setup sequence it tightens all belts but stays in the center with the alarm saying my center is off and my frame size is invalid. I really appreciate the help.
As a side note when I do the usb flash it erases and replaces all system files right? Firmware, index and yaml files correct? Or is there something I need to delete before the install.
193 shouldn’t be an issue. When it was 2625 that seems way off. A perfectly square frame would have tlx as 0.
Yes, it should be erasing all of the files.
There are two things that won’t get erased. 1) The gcode files on the “sd card” 2) the z-axis position which is stored in memory every time the machine loads
Just to make sure that the tlx value isn’t the issue, it’s not changing from what you set it to, right? Like there isn’t something weird going on there where it keeps jumping to big numbers?
If you are referring to the number I changed then changed back no it is the same number the few times I’ve looked.

It’s the same number as in pretty small like 193 not 2625?
Can you post your Maslow.yaml file again? That number seems like our best lead right now.
So I got the board you sent me and I had ordered some encoder boards at the same time. To cover all the bases I disassembled the machine sanded the spools (free spin now like a bike tire on both halves), dry teflon lube on everything (it’s everywhere in my shop now thanks to a failed fan mount), replaced control board (installed 1.10 and associated files several times…several), replaced encoder boards, ensured motor gear grub screws are tight and gear the stated distance away from the bottom of the arm half and backed off from the idler gear, ensured magnets were secure and on the correct side of the belt under the encoder, ensured I did not over tighten arm screws (barely tightened at all, a little worried about that but I have a habit of over tightening) and did a few more frame securing measures. Not sure what the real fix was but now…..Retract and calibrate at 800 (belts plenty tight at this setting during calibration maybe felt a little too tight). 2000x1000 9x9 grid. 1.15 fitness (I rounded up 1.14 and some change). So can’t thank you guys enough for all the help. I will do a dry run in a few days then the real deal. Is there a thread for vertical setups in particular? Feed, speeds, issues, tuning,etc.?
Thanks again

Excellent progress! I am really glad to hear that
