No movement #1192

Mitch just wrote a new wiki page with a flow chart to help with that. Give it a try.

http://wiki.fluidnc.com/en/support/setup/motion

[MSG:WARN: Cannot open configuration file:config.yaml]]

That means that FluidNC cannot find your config file. If you uploaded it to a name other than “config.yaml”, you must tell FluidNC the name by sending “$config/filename=YOUR_CONFIG_NAME.yaml” in FluidTerm, or else set it via WebUI

I need to have 4 Y motors at the same time,

FluidNC does not directly support 4 motors on one axis. The most is 2 motors per axis. It might be possible to connect 2 motors to one driver and 2 motors to another driver.

Good evening Mitch,
Thank you for your advice. I got something moving, but goes with a lot of noise and sometimes back and forward. It looks as if there is not enough power or maybe too much. The motor (got one connected at the moment) does not get warm. Where should I start with this.
Thank you for your time.

Good evening,
Spend most of the weekend figuring out what is causing the motor not to move. It goes, slow, sometimes in different directions and makes a lot of noise. I went through the motor guide and still I have something that is not correct and maybe I do not understand everything correctly and being a Dutch guy that could be the case.
Got a yaml file from Github. Got TMC2130 and motors that are 1.5 ampere, 24 volts, 2.3 ohm, 1,8 deg. In any case I tried to change the current on the stepper, which is now 1.5 v also tried to lock the motors but I can’t get that to work only with using the $ME command. What am I missing? Can you help me please? Thank you in advance.

It goes, slow, sometimes in different directions and makes a lot of noise.

The usual cause of “slow, different directions, and noisy” is a bad connection between the stepper driver and the stepper motor. A stepper motor has two coils. Motion happens when coils A and B are energized in sequence – A B A B A B etc. – with a particular timing pattern (phase) and polarity. If there is a broken connection to one of the coils, the motor sees the pattern A _ A _ A _ instead. Instead of moving smoothly, the motor will sometimes move slowly with jerking, sometimes move in one direction for awhile then switch directions, and sometimes just sit there shaking.

The other things that can cause this behavior, in addition to a broken wire or bad connection, are

• The motor is bad – one of the coils inside has failed. That can be tested with a multimeter. The resistance across coil A should be the same as the resistance across coil B – typically a few ohms.
• The stepper driver has failed and can no longer energize one of the coils.

Those causes are listed in the order of most common to least common. Connections fail more frequently than motors. When a stepper driver fails, it usually fails so catastrophically that there is no motion at all, not just one coil driver.

http://wiki.fluidnc.com/en/support/faq#motor-moves-erratically

I measured the motor 2.5 ohms on both channels so that should be ok. Even put the two wires together and the motor was hard to move. Changed to a different driver, problem is the same. 6Pack is in SPI mode, card on 5 V, TMC2130 on 1.5 volts. When I send a movement command I measure about 21 volts. Still the motor makes a loud noise and goes back and forward. Do you have any other idea?

What do you have the Vcc set for?

https://github.com/bdring/6-Pack_CNC_Controller/wiki/Stepper-Jumper-Motor-Setup#stepper-jumper-motor-setup

On 5v

And I just read it should be 3.3v. Now I have no movement at all and not change in voltage on the motor.

You could try a different motor, or swapping that motor to a different stepper.

It should be 3.3v. The TMC2130 can run at either voltage, but SPI returns data to the ESP32 so it must be 3.3v or it can break the ESP32.

It usually does not hurt in the short term, but definately leave it at 3.3v.

Can you show us your startup messages?

Do you mean the yaml file or something else?

Try sending $MD and $ME commands. Check the lock state after each command.

No it does not lock, but does for a few second after reboot. If I make a bridge between 1A and 1B the resistance is higher but not a lock.
Just to be sure, A- to 2A, A+ to 1A, B- to 2B and B+ to 1B

The each coil mounts to adjacent terminals.

Ok, so I reconnected it to the picture above. It all stays the same, locks when I reboot for a few seconds and then you can move the stepper again. Do you have any other ideas?

$ME does not lock the motors?

No

I am running out of ideas.

Try changing  idle_ms: 250 in your config to 255

Changed, no result. $ME has no effect. It still makes me think why the motor unlocks after reboot. Could that be a thing?
I connected a different brand stepper motor just a moment ago and there is no change.

That is strange, but I have tried to test everything I can think of regarding that.

Send $axes/x and paste the results.

You could try adding :low after disable_pin: I2SO.0

I doubt it will work, but it is the only thing I can think of.

I think I found it, I let you know tomorrow if I am right. Hardware issue, but not the card.

Sometimes if it locks for a few seconds, then unlocks, it is because the driver overheated and shut down to protect itself. I have also seen cases where the power supply shut down or glitched, causing the driver to shut down.
