Strange moving trajectory at top area

Well I would be appreciated, however I live outside US, very far, it would take 2 weeks to ship to me new PCB. So let me first try to switch motors’ places and see if the left side still got that issue, that would mean the problem in controller. However right now I have to go on a 3 days trip, so I will try that when I’m back.

What I saw was like this


This is just Gimped, as I did not cut clockwise but followed the sled closely and it would have cut as seen here.

@S1lver Will you send me your address anyway, that way the board can be on it’s way to you while you are on the trip. It might not be needed, but I would rather send you one you don’t need than make you wait

yes it is similar, the pattern will mirror.

For me that excludes the motors. I bought a power supply with 10 amps and the error was gone. I suspect that my power supply could not deliver what was needed.

Interesting, I use a PC power supply the same way I use for 3D printer, it deliver 20A max for 12v. I got a 30A power supply laying around I should try it out.

If you have 20A that is more then enough. The stock Maslow has a 5A supply.

put a meter on the power supply output, see if the voltage is dipping when you
are having this problem

After putting new power supply, it solved the problem. Seem like something was wrong with my previous one. Thanks for the suggestion.

Good to hear it’s solved! I just replaced it as a guess, but now I’m tempted to put the old one back for amp and voltage measure.
