Hello,

I am setting up my Liteplacer and already solved a lot of problems. But now I do not have any idea:

when I start placing the Liteplacer picks up the part which is nice. But then the needle goes up and then I get an Error "Attempt to Move while Nozzle is down". "OK" terminates the show. So Liteplacer pics up the part and terminates with this nozzle down error despite nozzle is already up again.

Homing and Calibrating of Z works fine and is done.

Here is the log of this Error

Your TinyG settings have a nan (not a number) on ja and ct parameters. I don't really know what these mean, but to correct, send these:

$ja=100000
$ct=0.01

Please report back if these correct it.

The logs show, that TinyG responds to G0 Z0 command (goto z0 using default speed) with status report that doesn't make sense (Z position 29.921, previous command successfully done). It the above doesn't get TinyG to its senses, I have to look really deep into this (and I will).

Hello JuKu,

thanks for very fast reply.

No, It did not work. But I figured out that it seems to be caused by
[sv] status report verbosity 2 [0=off,1=filtered,2=verbose]

should be
[sv] status report verbosity 1 [0=off,1=filtered,2=verbose]

Seems that I made a very time consuming error at the begin of the setup: I did not press “Reset All to Built-in Defaults” Button at the begin. Due to this I had a lot of errors, most of them I found a solution here in forum (e.g. wrong setting AAM for A-Motor resulting in endless turning, wrong setting XTM and YTM resulting in termination of homing etc.). So I assume that there are some users who skipped the Default Button, too.

So I am thinking if I should press the default-Value Button now, make me trash all my settings. Or I will compare to your GOODSETTING.TXT and change values in my system step by step (skipping values where I know that these are correct.)

If I will have a new problem I will check GOODSETTINGS.TXT first...

Now I am very happy with LitePlacer has placed the very first 1206

Thanks
Sven

Your settings seem to be mostly fine, so I think that comparing to the reference makes most sense at this point. Glad you solved it.
