Thanks, I'll check out those videos when I'm home.

Thanks for the info.

One more for you, Chris.

Chris built a Dolly (it's posted on this forum). Like mine, it is 12v with the Trinamic drivers. Moorviper is right about them being a challenge to set up, but it is possible.

lots of viewing, but i have watched those videos.

Not sure if i was missing the point, but i didn't get much that i didn't already know from the first 3 videos. I haven't even got the steppers working well enough yet to see if they are whining. If i have missed a clear bit of help here, please feel free to spell it out for me, it's been a hard day at work and my brain is just about limping along.

The second video, raised one concern (I can't remember that if i have disabled SD support - but i will check when i get to my laptop with the Firmware on it).

One thing that seemed to be a resounding message from all videos is that it might be best to go 24v and get some 1 amp steppers. I don't know what comes stock with the anet a8, but it might be better to get some that i know stats on than try and continue with ones that don't might be part of the problem.

All that said, i still feel like there is an error here that i can't clear. As you say getting these working on a 12v system is a challenge, are there any things to check, or be aware of when setting them up on a 12v system? Like common faults?

Not against upgrading to 24v but i want to be sure it will fix the issue, and i wont just get the same error message.

Thanks a lot for your help so far, both of you.

I have confirmed that SD support is disabled my firmware. As i use octoprint i don't feel the need for a screen or SD card at the moment.

My printer has an auto bed levelling sensor, according to Chris' basement vid, i shouldn't need to hook up the diag pin to the signal on the endstop. Should this be put elsewhere? or can i just leave it unplugged?

Still lost as to what the error with my Y driver can be. Any more things to check?

Update!

I decided to take out the 2130 on the Z. as I figured this was another problem I couldn't be bothered with just yet.

In doing this, the error with the Y has stopped, and both A and Y Axis work.

i am happy enough with this. Thanks for your help!

Now I just need to work out why my PSU has decided to stop working.

yes normally x+y are enough
z and e are normally not moving that much

only if lift on retract is enabled

Interesting. I've previously noticed that Marlin did not necessarily report the correct driver's error, though I don't know why. My understanding is that the z-steppers should be powered by two drivers rather than one in parallel, especially if running at 12 volts. (I'm using an A4988 on my z-axis and extruder.)

Glad to hear the progress!

It is a bit odd as it also seemed to invent an error for the y as when I disabled the monitor line the y axis wouldn't move and just made noise. It might have been a power thing I guess? If they are relatively hungry it would make sense that all I did was reduce the load and it worked.

While it might sound like a cop out I'm going to call this one done and get nack to printing rather than upgrading.

2100 for e and z
2130 for x and y

All should be quiet enough and still give me an element of control.

Plus side, I do have enough spare 2130s to do the same on my resurrected da vinci! So there is a positive!

Once again, thank you, I really appreciate the help.

Hi guys,
I'm replying to this topic as I also have a "sound"-related TMC2130 issue.
In my case, I'm still building my printer so X and Z aren't complete yet, but I did assemble the Y already.
The weird thing is that it's basically quieter in spreadCycle than in stealthChop!
In spreadCycle, you can hear a pretty loud whining noise, but in stealthChop the motor buzzes like crazy at almost the same volume!
Any help is appreciated,
Thanks!
Dave

Hi Dave,

The 2130s don't seem to be too quiet if you tell them to go 10mm. I thought I'd done something wrong when I first installed them. They are much quieter when actually printing. Also, bring the current down as much as you can.
