Place here button

[roberto_imai]

Everytime I use the place here button, I get a tinyg reset.
What can I do to prevent this?
Is there a way to adjust the Z for "Pickup this" and "Place here" buttons?

[JuKu]

What should happen is that the mcahine moves to the location shown on the camera; Z axis goes down slowly until the switch triggers (it does not know the Z height, so it probes it); Z axis backs off until the switch releases; vacuum is swithced off; Z raises and machine moves to the starting location, showing the result is camera.

If you get a reset, a limit switch is triggered when not expected. I'm guessing that either the vacuum or motor noise couples to the switch and you have a noise issue or the tube movement is restricted, keeping the switch closed.

[roberto_imai]

Yes, it hits the upper Z limit switch and resets.

Here is a video:
https://www.dropbox.com/s/9ytdguvtfr8b8 ... 5.mp4?dl=0
As you can see at the end of the video, the high Z limit switch gets triggered and it goes into halt.
Is it what is causing the error?

[JuKu]

> Is it what is causing the error?

Yes. The question is why it is doing that; it is supposed to return to normal Z0 level. Please restart the machine (so that startup conversation gets in the log, click place here (no need to pick up anything) and send me the full log window content (click in the log window, ctrl+A to select all, copy and paste to a text document).

[roberto_imai]

Ok, so here is what I did.
Turn on
Home
Place here
It went to calibrate the nozzle
Came back and did a successful place here
Place here again
Halted

I'm traveling right now (I'm back in the office on Wednesday), so I don't have my machine to compare. Just by reading it, I don't see anything odd, other than hitting the switch when it is not supposed to. When that happens, it is already decelerating and almost stopped. (The last periodic position report says 0.128mm to go, and a small fraction of speed left.)

Please try slower Z settings and perhaps faster homing acceleration, as well as checking how much more the tube could go up when the lower switch triggers. My theory at this point is that when the machine is probing down, first the switch triggers. The head starts to decelerate, using the homing acceleration setting. Before it has time to reach a complete stop, it hits the physical limit, set by the shaft collar. The z motor loses a step or two, and the head is not as low as the software thinks it is. Therefore, when going up, it goes too far.

[roberto_imai]

Which Z settings?
On basic setup, I have 4 fields for acceleration and speed and then home acceleration and speed.
When I change them, they don't seem to take effect.
Do I need to click "Load user defaults to TinyG" button for them to be used?

[JuKu]

The probing is done by home speed and acceleration settings, regular moves by the other speed and acceleration settings. If my guess is correct, lower homing speed and larger homing acceleration would cure it.

When you change a setting, it turns red to indicate that the setting in the user interface is different from the setting in TinyG. Pressing enter will write the setting to TinyG.

[roberto_imai]

Yes, that worked.
Thanks!!

[sebastian]

I noticed the same issue on my machine, what speed/acceleration speed settings did you use in the end?
