Please correct me, if I am wrong, but if I will change this line:
81 genser-links[t].quantity = GO_QUANTITY_ANGLE;
to this one:
81 genser-links[t].quantity = GO_QUANTITY_LENGTH;
then it will change all the joints from angular to linear.

Since my impression is that the TYPE(t) value cannot be set to
GO_QUANTITY_LENGTH or GO_QUANTITY_ANGLE, but rather it will be either
1 or 0, determining, if joint is angular or linear, I would like to
ask, if anyone could comment, which of the following examples of code

You might look at the kinematics for a SCADA arm for some hints, it is
a very rudimentary version of what you are doing.
Nope, scarakins uses very simple calculations with sin and cos
functions. It seems to me that from mathematics point of view

Hi Viesturs,
I wanted to reply to your private email too (same matter) but didn't get
around to it.
Let me try to address your questions one at a time:

The kinematics in emc2 don't care if it's the arm or the workpiece that
move. they both move relative to each other, so you have to take care of
both in your kinematic file.
If only the workpiece rotates then surely it's a lot simpler and your

orientation is significantly less so.
Yes, generalising something makes everything pretty difficult, because
it has

Yes, that is correct

Thanks, Alex! I start feeling like I do understand something :)

the adding HAL pins looks ok, but one would need to test/debug it to say
that it's 100% ok.
How are the simulated machines created? I suspect that there was

Hello, folks!
Genserkins.c says that Currently the type of the joints is hardcoded
to ANGULAR.
I would appreciate, if anyone could share some advice, how the linear
joint could be implemented.
My need is to move small robot arm along 3000 mm long linear slide in
implementation of robotic MIG
