4.1 Calibration Issues and Questions

[boslaw]

@bar

This looks totally normal to me. The green light on the PCB being off here means that it’s a power supply issue. Is there any chance that the outlet that it’s plugged into could be an issue?

the outlet is not the problem. I use that outlet regularly and have a car battery tender plugged into it 24x7 and it never turns off. Probably a power supply or board issue with the Maslow. Just one more problem to deal with. The power supply is new as shipped - been used for 1 week so far before this happened.

@boslaw Will you start a new thread for your issue so that we can keep this one for @caddad?

@Justin_Walker

The soldered connector pins extend past the board a significant amount. So much so that they might come into contact with the bearings below them and short.

I think that this is only true for the JST-XH encoder boards, the older ones with the ethernet connectors I think aren’t over the bearings enough, but I could be wrong about that.

Can you try swapping the wires around? Sometimes just unplugging and re-plugging everything can fix a connection issue like that

[Justin_Walker]

I’m having the same issue.

[bar]

There are a LOT of different issues listed in this thread. Can you start a new thread describing your issue?

[caddad]

@bar I just swapped the cables around and have the same issue. test passed, but reading didn’t.

I echo starting new threads for issues not like mine.

If the test passes, but it’s not detecting any movement, there are two
possibilities

1. the magnet is in the wrong place on that arm (or slipping)
2. the encoder chip is working well enough to talk to the main board, but is
   broken enough to not read.

it’s FAR more likely to be the magnet.

i wasnt having this issue before and its occurring with two encoders. I checked the magnet during reassembly per this thread’s emphasis. I only disassembled one arm.

could it be the main board?

[bar]

I don’t think this is the magnet, this to me looks like there is something interrupting the communication between the main board and the encoder boards.

Since all of the encoders are on the same I2C bus something funky with the bus can impact multiple encoders. (IE a faulty connection to one might show up as one taking so long to respond that it messes up with the next one or something like that)

switch connectors around to see if the problem follows one arm.

bar will need to comment.

@dlang i already did that. see my previous posts.

@bar so what do i try next?

[bar]

I am a little bit stumped.

I’m going to DM you a code for free replacement parts and I think it’s probably worth just getting a new controller, new wires, and four new encoder boards.

I’m pretty sure that only one of those things is needed, but the fastest way to find out which it is is to be able to swap each part out and see which fixes the issue.

You don’t need to take the whole machine apart to do that, the encoder boards will work plugged into the controller without being installed on the arms

[caddad]

Thank you! How do you suggest I determine the issue source once the parts arrive? It’s easiest for me to just swap everything out, but that wont help you for similar problems in the future.
