Acrylic display windows
In the FAQ section of this website it says that I can add a display window to my panel by using a rectangle-in-rectangle shape. I have a 16" x 5" x 0.125" black anodized aluminum panel to which I'd like to add a tinted display window. Can you help me with the following questions please:
1. What thicknesses of acrylic do you offer?
2. What tints of acrylic are available?
3. How do I specify my choice in the Front Panel software?
Many thanks,
Carl

ReplyCan the Plexiglass Red Filter you offer be used
for VFD or LED Display Filters.?
Posted By: Jorge de la Paz on Jan 02, 2010 04:13AM
ReplyWe offer the brand Plexiglas GS from Evionik (Product description) for both clear and red acrylics.
You can find the optical properties on page 6. It has a pretty good transmittance percentage of 92 and blocks UV. Basically, it depends on what kind of filter you are looking for. There are acrylics available on the market with integrated light guiding material or non glare surface texture.
If you are looking for UV protection and a couple of percent in transmittance loss aren't a problem, our plexiglas will be usable as VFD or LED display filters.

Reply(1) For transparent/translucent plastic materials , pLease add Clear Lexan (Polycarbonate) material to your available materials. In many instances the proximity of a polystrene or plexiglass material to an lcd or other electronics can build up a static charge and transmit it to the lcd/electronics ,possibly zapping it.
(2) For Opague plastic materials ,please add ABS materials like black. No issues with static unlike Plexiglass/POlystyrene materials.

ReplyHello Jeff,
I can sympathize with you in regards to static discharge. Having worked for many years in the plastics industry, I can offer some insight.
Both polycarbonate and acrylic will have immense static discharge potential, but this appears to be more of an issue with the masking that is placed over the sheet. A sheet with poly-mask will have immense discharge capability (I have experienced a 1/4" arc from a sheet of 3mm polycarbonate), while a sheet with paper masking tends to have almost none. At Front Panel Express, we always remove the masking on any sheet we machine, and it sits on a giant grounded metal mill for significant periods of time. When the plastic is packed, if two pieces of plastic are to be packed one on top of the other, a piece of tissue paper will be placed between them. I would imagine, however, that a material like FPVC might still have issues, even with those efforts taken.
We are able to machine plenty of different opaque plastic materials, and we can special order these quite easily. For the amount of this type of machining that we do, it does not make a ton of sense to keep all of these materials around. For something like black ABS, you will typically see one day added to your order for us to receive the material.
Many thanks,
-Paul

ReplyHi,
On this page, it is mentioned that the clear acrylic comes in thickness from 2mm to 10mm.
But, in the quoted post (below) and in designer, the maximal thickness is 4mm.
1. We offer plexiglas in 2, 3 and 4 mm thickness. See here
What information is good, because I would like to make a led edge-lit window whit engraving. So I will need a thickness of 6mm minimum.
Thanks
Julien

ReplyHello Julien,
The forum post is from 2009 and outdated. You can order clear acrylic up to 10mm in thickness.
Best regards,

Vector support?
Hello.
Why can't a user cannot generate a design in a vector program, such as Illustrator or Corel Draw for the cuts and import to Front Panel Designer? Some of us have fully-designed setups already in vector, so this would save a lot of time versus having to needlessly redraw them in your software.
Posted By: Jeremy B on Dec 08, 2008 06:36PM Category: Front Panel Designer
Hello Jeremy,
A vector import does not bring information of the z-axis. Everything with 'depth information' as countersinks, cavities or threaded holes would not be correctly defined.
We are working on an import option in Front Panel Designer to allow more complex shapes. This will be available with the next version. We will keep you informed about the release date.

Bulged Rectangle
Hi, just wanted to introduce myself and a problem that has me stuck. I'm Jeff and having a heck of a time trying to figure out how to make a bulged rectangle for the shape of my panel. The panel will fit in A Seahorse 520 case which has radiused sides and corners and is not a perfect rectangle. I've tried to used the curved slot tool to shape the rectangle but it's giving me fits and I just can't seem to get it right. I'm computer savy but not Cad savy so there is a bit of a learing curve. If I can get the basic panel shape down adding the rest of the data shouldn't be an issue. Below is a picture of the panel with dimensions and I am hoping that someone can help me figure out how to successfully draw the basic panel shape or give me some advice on what I need to do. I would be nice if there were a template for cases like these or if we could import a DXF file (I have this drawn in Autocad). ANy help would be appreciated:
Posted By: Jeff Schaber on Dec 02, 2008 08:45PM Category: Front Panel Designer
Hi Jeff,
You don't have to to design this shape in Front Panel Designer. The combination of several curved slots can be tricky especially when smooth arc-arc transitions are needed. We can import dxf files for 'complicated' outer shapes in our milling files so that panels aren't only restricted to rectangular or circular shapes.
In Detail:
Just design the panel in a rectangular shape (in your case 14.17" x 16.63").
Place all cutouts and engravings as wanted. Please add a note for us that you want the shape modified by dxf import and submit your order as usual. As soon as we receive your dxf file (please send to order@frontpanelexpress.com with the reference number of your order) we will let you know the additional cost for the modification, usually between $15 and $45.
It is also possible to provide just a pdf with the dimensions you want and let us do the rest.

Suggestions for polishing raw aluminum
I've so far only worked with anodized aluminum, and I'm wondering if anybody's had luck in getting a nice polished shine from the raw aluminum.
I was thinking of getting a bottle of Mother's Aluminum Polish, but the panels themself won't be cheap, so I'd rather not experiment.
I've read that only some types of aluminum alloys polish well.
Another concern after polishing is keeping the polished shine. I'm guessing something like everbrite, carnauba or some other clear wax, polyurethane clear coat, etc..
Does anybody have suggestions?
Thanks
~James

Machining on edges / perpendicular faces
In the thread titled "Beveled edges" it was revealed that a part can be machined on its edge if the material is thick enough. What are the constraints to this?
For example, can I machine a M2 hole in 4mm material? What position tolerance is there between features machined on the front and features machined on the edge?
Also, is it possible to machine on the perpendicular faces of right-angle aluminum? I have a section of aluminum which appears similar to this:
The sides are 25.4mm wide and 3.2mm thick. Is it possible to machine on the two outside faces of this material? How about the inside faces?
Thanks!

For example, can I machine a M2 hole in 4mm material? What position tolerance is there between features machined on the front and features machined on the edge?
That is possible. Our position tolerance of objects on different sides/edges is +/- 0.1mm. M2 in a 4mm panel works fine, M3 would be pretty tight and is not recommended.
You can set up your design as the following:
- Design an additional panel with height of 4mm and length in accordance to the front panel. This will give you the top view on the edge. Choose 4mm thickness, we will fix the panel thickness for you later. You can go up to 4.5mm deep with a M2 hole.
- Check the box for customer's material, the material price is already included in the front panel.
- Place the M2 holes where needed. Please let us know how the holes are related to the front if they are not symmetric (a note in "Remarks" is fine).
Also, is it possible to machine on the perpendicular faces of right-angle aluminum? The sides are 25.4mm wide and 3.2mm thick. Is it possible to machine on the two outside faces of this material? How about the inside faces?
In general, yes for the outside. But it depends on your design, e.g. distance to edges etc. Inside is a little more tricky and really depends on what you want to have cut or engraved. I can give you a more specific answer if you could provide a drawing or even better a Front Panel Designer file.

Diane

Scale Generator
How do you install and run Scale Generator?
Posted By: Don Cleveland on Nov 07, 2008 08:05PM Category: Front Panel Designer
Scale Generator is based on java script, and requires the Java runtime to be installed to allow it to execute.
If you already have Java installed you should be able to double-click the jskala_english.jar file to launch it.
If you don't have Java installed, the simplest way to get it is to visit , click the 'Java Software Free Download' link in the top-left and follow the instructions there.
Posted By: Diane Haensel on Nov 08, 2008 10:38PM

ReplyHi Don,
the download for the Scale Generator can be found in the Tips & Tricks section.

I've searched, but cannot find jskala_english.jar, is it
part of the Zip file?
Posted By: Don Cleveland on Nov 21, 2008 05:41PM

ReplyHi Don,
I'm glad you got it to work. The problem was a combination of the versions of Internet Explorer and Java. Not all versions work well together. We recommend to keep both IE and Java up to date to ensure Scale Generator is working on your computer.
Thank you for pointing that out for us.

ReplyScale generator.
As well as Don, I’m unable to download “Jaskala_englis.jar” even if I update my Java runtime (6/16)and re-downloaded Front Panel Design as well as Scale gen from Tips and Tricks.
When I unzipped “Jaskala_english.zip”, no “ jaskala_english.jar” shows up.
Any turn-around?
If nothing else, could you please be so kind and e-mail it me?
Thank you

ReplyHi Jakester,
Did you specify the target directory or did you just enter the file name? You also need to add the extension .plt to your file name.
An instruction about Scale Generator can be found here
I am sorry for the inconvenience. Please do not hesitate to call us in case you still have problems to get it to work. Our customer service would be more than happy to walk you through Scale Generator.

my email address.Would appreciate any help on this....
thank you.

ReplyHello,
I can see how people have this problem since java is a pain to manage. This is what I did (and worked from me):
1. Uninstall Java. I like to use the free version of revo uninstaller () since it deletes all registry entries as well as dlls and temp files. If you're going to use this program chose the advanced option.
2. Re-install Java. Go to and use the offline option. Please make sure to only install java and remember your file destination (which you can customize as well).
3. Go to and click on the "Scale Generator - Script for generating scales" link. If everything has gone right you should see a small window .

ReplyThe center point of the scale is offset upwards. Could use advice in setting it right.
Posted By: Randy Humbert on Jul 21, 2010 05:54PM
ReplyHello Randy,
When you generate the scale, the "Length" box determines the diameter of the inner circle from which the scale marks emanate. The overall object size then is dependent on not only that angle, but also the lengths of the segment marks, and which segment marks are at the largest extremes. As the segment marks have two available lengths the actual "size" that the scale becomes in Front Panel Designer is a fairly complicated size to calculate.
Given all of that information, I would make a temporary hole with the diameter of the length specified for the scale.
Place that hole over the hole where the scale will go. (Align/distribute makes this easier)
Be sure your grid is turned off, then drag the scale over that hole until the indexing marks line up so that they are all perpendicular to the temporary hole.
Delete the temporary hole, then group the original hole and the scale to keep them together.
I started to whip out a fancy formula for calculating the vertical displacement from the scale center, but it quickly became overly cumbersome.

ReplySOLVED THE PROBLEM!
The issue of this problem lays in use of 7Zip program (or similar programs) that has an ANNOYING "helping" function in renaming files with the extention ".jar" to ".zip" .
Sollution! -> RENAME THE “Jaskala_english.ZIP” TO “ jaskala_english.JAR” (Used large letters only to ease the viewing of the matter. :wink: )
The other issue with "CANT FIND ANY PLT FILE!" is because YOU have to add the ".PLT" at the end of your file so that FrontPanelExpress will be able to se it. Either do this inside Scale Generator when naming your file or do it manualy in by marking the file, press F2 and place the cursor at the end of the filename and add .plt to it.
Happy Scaling!

I want to add a little more information to this thought. A lot of customers still have this problem and I blame it mostly on Microsoft Internet Explorer! IE is trying to protect you by renaming .jar file as a .zip file. You can turn this feature off by:
1. In the upper-right corner of IE8, click on Tools to open the drop down menu;
2. At the bottom of the Tools menu, click Internet Options;
3. In the Internet Options dialog box, select the Security tab;
4. On the Security tab, select the Internet zone, then click the Custom Level button;
5. Scroll about 2/3 down the list to the option "Open file based on content, not file extension" and change the setting to Disable;
6. Click OK;
7. Repeat steps 4-6 for the Local Intranet zone and Trusted Sites zone;
I'm sure it's very similar for IE9 that went live just recently. Another suggestion would be to use a different browser.
I hope this helps!
