I decided to start over down to updating the software just like a new machine. I’ve gotten the arms to extend and retract, release tension, but cannot get the z axis to lower. The motors run up and clicks when at the top, but the motors do not run for the down command. I think that may be the problem for the calibrate command.
Stuck again!

So the z-axis works in the up direction, but not in the down direction? That is a strange one.
Not absolutely sure that it works in the up direction. It’s set at the top of the range and when you go up, it clicks to show you it’s all the way up. It just will not lower.

Do the motors spin when it should be going lower and it just doesn’t move, or do the motors not spin?
The motors do not move going down, but do going up.

@bar, sounds like it could be a corrupted maslow.yaml file that isn’t defining
the direction pin properly (assuming it’s not a hardware problem)

Could I delete the yaml file and reload a new one?

I deleted all the software and reloaded the current version. Tried lowering the unit, it didn’t move. Tried raising it, the screws turned and it clicked indicating that it was at the top. Extended all belts, tightened all belts, and released tension. Tried to run calibrate and it says cannot run calibration until all axis are extended fully - No heartbeat from machine in 10 seconds. Please check connection.
I know the machine is connected, because those other functions continue to work.
Stumped again!

Did you change out your index.html and maslow.yaml?
Since you reloaded, how are you connecting to the machine? Directly to the WiFi, or via maslow.local?
I know you must be super frustrated, hang in there though, it’s pretty fun to watch it cut stuff out when it actually works!

I think that might be your problem with running calibration. I don’t think you can run calibration without having the belts fully tightened. Ie, you extend, retract, calibrate, in that order, no extra steps. Why your z motor won’t go down I am at a loss.

I’m connected thru Maslow.local. I turned the machine upside down and turned the screws by hand to lower the machine about half way.
I did as you said, extended all, retracted all and tried to calibrate. Still wouldn’t cooperate.
Although I think it’s connected, I still get the no heartbeat message, please check connection.

Did you change the index.html? I see you did the maslow, but I think both need to be done.

I deleted all software and downloaded the newest version, including the index.html. I also went through the steps, extent, retract but the results were the same.

Let’s make 100% sure that it’s not a mechanical issue.
If you move the Z-axis all the way up so that it clicks and the machine can be lifted off the top of the lead screws then while holding it up so the machine isn’t on the z-axis lead screws press the down button do the z-axis motors spin?
The goal here is to test the motors when there is absolutely nothing connected to them.
I’ll try that when I get home from work

I have run this scenario 5 0r 6 times. I would set the up at 30 and it will go all the way up, even out of the screws. I would set it to 5 or 0 and it went down twice. I ran it all the way out and lifted it off the screws and ran it up and the screws turned, i set the down at both 5 and 0 but the screws did not turn at all. It seems that the motors are not working properly.
