Hi Ken,<br>
<br>
Concerning the Ethernet-based XPS-C6 controller, do you know if all
you have to do is tell the controller to go to some 6-axis position,
or do you have to direct the controller to get there axis-by-axis,
or must you do something even more complicated (e.g. start motor,
speed up, slow down, brake, stop, check where you are, repeat, check
for overshoot, back up, etc)?<br>
<br>
Our preference of course is to simply use a single command to tell
it where to go and not worry how it gets there.<br>
<br>
Thanks,<br>
<br>
<br>

Here's what I hope is a final design for the goniometer. Still to get a quote and confirmation that we can get all these stages vacuum compatible.
Any questions or comments ?
Cheers,

Hello Ken,
Thanks for the files. I've attached a more developed concept drawing with the requested stages. I'm still working with our factory to make sure we can provide the BGS80 and URS100 in vacuum. I don't think this will be an issue, but waiting on confirmation from suppliers for the vacuum compatible components.
So please stay tune and I will keep you updated.
Thanks,
Phong

Hi Phong,
Thanks for the update.
I think we'll have to go with the MTM100PE1V6 vertical translation,
since there seems to be no other option. However, I've noticed a couple
of other crucial differences between the quoted specifications and those
outlined in my original. I've noted these below as comments after each
axis as described in the quote. I've also attached a pdf made by our own
CAD expert using step file from the Newport web site showing
approximately the layout we'd like. I'm trying to keep the overall
dimensions to a minimum since this will need to go in a vacuum chamber.
I'll be in Jefferson Lab next week and will meet the engineers for the
project and discuss the specs with them. If you can magage to address
any of these issues before that I'd really appreciate it.
Regards,
Ken

<pre wrap="">Hello Ken,
I just wanted to follow up with you. I believe the quote should have
been generated for you. If you have any questions about the quote,
please let me know and I can assist.
In regards to the GTS30V, I have spoke with our factory and we won't
have the capabilities to find the correct components that would allow
this stage to be vacuum compatible at 10-6. So I believe our option
would remain the same as what is quoted. I've attached the concept
drawing again, but this time with the vertical set to the side.
One thing I wanted to find out if you had a time frame that was needed
for the system? I know the quote states 12 weeks, but this could be
pulled in.
Best regards,
Phong

Hi Phong,
Thanks. This is very useful.
A vacuum level of 10-6 torr is fine.
I would appreciate a quote for the parts with assembly, and an update
when you get some information on a vacuum version of the GTS30V
<a class="moz-txt-link-rfc2396E" href="http://search.newport.com/?q=*&x2=sku&q2=GTS30V"><http://search.newport.com/?q=*&x2=sku&q2=GTS30V></a>.
We managed to find step files for some, but not all of the components.
Is there a single download somewhere with a library of the components?
Or a directory on the web?
Regards,
Ken

The XPS-C6 <a class="moz-txt-link-rfc2396E" href="http://search.newport.com/?q=*&x2=sku&q2=XPS-C6"><http://search.newport.com/?q=*&x2=sku&q2=XPS-C6></a> would be
the recommended controller and the driver cards would be (5) XPS-DRV01
<a class="moz-txt-link-rfc2396E" href="http://search.newport.com/?q=*&x2=sku&q2=XPS-DRV01"><http://search.newport.com/?q=*&x2=sku&q2=XPS-DRV01></a>.
With the XPS controller the communication is now through Ethernet. The
XPS does have drivers for other software such as LabVIEW, Matlab.
Also it does contain a GUI and you can develop TCL scripts. Many
options and you can find more details from the link under Downloads.
I do have a question, as I have been assuming vacuum level at 10-6
Torr, is this correct?
If you do need a quote for the above parts with assembly, I can
provide that for now until I can gather more information about a
vacuum version of the GTS30V

Subject: Re: goniometer quote and design
Hi Phong,
We discussed the drawing you sent, but like me the others wanted more
details. Ideally, we'd like to get rid of the very large vertical stage
which would dictate the size of the vacuum chamber.
I'd like to know which motor stages from the Newport Range are in your
current design, so that we can look at specifications and prices. Can
you please let me have that information. As I said in the previous mail,
it would be ideal if we had access to the AUTOCAD/STEP files. :
"We have an autocad specialist in the group, who has developed similar
designs in the past using the autocad / step files which are available
for the THORLABS motion stages. Ideally we'd like to do the
configuration ourselves in autocad, using your design as a starting
point. Would it be possible for you to give us the information we
require to do this? eg step files for the different motor stages and a
recommendation of the possible stages we can use, and the details of
those which are in your drawing."
Controller.
Can you let me know which controller you advise for this system.
We want to be able to send sequences of commands from our own computer
programs - currently we do this on an RS-232 line using MM2000 type
controllers.
Regards,
Ken
