Make sure OpenPnP is closed when editing machine.xml, or it will get overwritten.

Hi Behnam

you could probably do that by using a PushPullFeeder. Then create a PUSH_PULL Actuator that has its X mapped to a separate X axis and Y mapped to nothing. hat is done by AxisMapping.

P.S. be a bit more patient for answers :-)

... Sorry, it just occured to me that this won't work. While you can do the "hail the taxi"-move (i.e. move the tape holder underneath the nozzle), the absolute pick location will still be done and that's not what you want. :-(

Hi,
I've some simple idea but need to test it first at my side. Do you use 1.0 stable or 2.0 develop version?

[Marek T.]

Add AutoFeeder and close Openpnp.

Edit machine.xml and replace X/Y coordinates of this feeder with NaN instead of the 0/0.

You need to test it on your own, I cannot today. It may have a chance to work as you want but not 100% warranty.

Note that this method, may don't work properly in the future after when some Openpnp 2.0 updates will stop it.

Hi i try and not work
I edite and save
During open openpnp have error and not open

[Behnam Max]

Can i try by javascript?
Or new feeder class

[Behnam Max]

I have made feeder on head it is good idea for led placment pleas help me jason

[Marek T.]

I must didn't do literally what I said. I just did the same in Openpnp 1.0 and 2.0, and both are opening properly.

Sample part of machine copied from 2.0:

         </feeder>
         <feeder class="org.openpnp.machine.reference.feeder.ReferenceAutoFeeder" id="FDR1586902516014" name="ReferenceAutoFeeder" enabled="true" part-id="R0805-1K" retry-count="2" pick-retry-count="2" actuator-type="Double" actuator-value="0.0" post-pick-actuator-type="Double" post-pick-actuator-value="0.0" move-before-feed="false">
            <location units="Millimeters" x="NaN" y="NaN" z="0.0" rotation="0.0"/>
         </feeder>

Hi

You need to provide much more information, a log etc.

Read this:

https://github.com/openpnp/openpnp/wiki/FAQ

Specifically:

https://github.com/openpnp/openpnp/wiki/FAQ#how-do-i-turn-on-debug-logging

If there is a language problem, use one of the online translation machines, the've become quite good.

Tell which version of Openpnp you have, 1.0 or 2.0.
Provide your machine.xml file.

I can't see any error when run Openpnp with modification that I told you. When do you get an error?
