I'm using hitech pwm servos with ezbv4. The movement range is 180 or more, but ezb software doesn't allow the whole range.
Can Synthiam make a plug-in for configuring the range as required ?

i think this topic answers your question.
degree servo
The question you are asking is related to the ezrobot ezb v4 hardware product. That product is made and sold by ezrobot, not synthiam. You can contact ezrobot on their website. Similarly to how Microsoft makes windows but your laptop is made by Dell or Acer, etc...
however, since I took part in designing the ezb v4 for ezrobot, I have an answer. The ezrobot ezb v4 follows the standard for servos. The servo you purchased does not.
of course, you’ll want a solution. There are two...
1) use an arduino as an ezb because (I believe) you can customize the pwm range. I haven’t done it but I seem to recall seeing a parameter in the servo library to adjust the pwm timing
2) use a ssc-32 add-on to the ezb v4. Actually, the ssc-32 will work with any ezb and also direct usb com port to. The plugin has the ability to adjust the pwm range. Here’s the link: https://synthiam.com/Products/Controls/Servo/SSC-32-Servo-Controller-16180
ezbv4 : an hardware made by ez robot firm
ARC : a software you made for ez robot firm when Synthiam didn't exist
Synthiam: a new firm making software , for everybody (including ez robot firm ).
ARC : a software you made as Synthiam , but [u]compatible with ARC

Synthiam is a company that makes software for programming robots. Just like Microsoft Windows is on your Acer or Asus or Dell computer. You cannot buy hardware from synthiam. Synthiam has a website at http://Synthiam.com that has information about what we do. You can click on links on that website and view software information - and what robots/hardware the software is compatible with.
ARC was created to work with a few robots and controllers. Ezrobot ezb v4, ezrobot ezb v3, ezrobot iotiny, Ssc-32, roomba, ar parrot drone, sphere, woweee mip, and a few others overtime. Eventually ARC also connected to arduino and raspberry pi.
ARC is outdated and is being replaced by Arc. ARC will cease to exist in the next few weeks, and ARC will take over.
Arc is only backward compatible to ARC projects. It’s not compatible with ARC.
An ezb is any device that is programmed to connect to ARC or ARC. Anything can become an ezb if it’s programmed to connect to ARC or ARC.
you mentioned ez-robot servos follow standard servos and the OP 's servo not.
I discovered the EZ-Robots servos timings by measuring and trial and error, ASFAIK there is no EZ-Robot information to clarify the intervals, neither i can find information regarding the "Standard Servo" timings, can you help post a link or clarify the intervals ?
The Lynxmotion SSC-32 uses (from the manual) a range of .5ms - 2.5ms.... I guess just for grins (since I don't own an oscilloscope) I could hook up an ez robot servo to an SSC-32 and test it's ranges....
