About FIVE_BAR or SCARA_TYPE 2
It is suported, but it may be broken (i just left old code but some artifacts may appear)
Last stable version (with fivebar tested) limited by changelist - 8e789cd9eb17dd5e8e8ee45dbc814715ddcb8e36 (11 Aug 2015)
When thinking about your parallel shifting arms...have you ever considered setting up a Printer built like a palletizing robot arm?
With your current software implemented inverse kinematics it should not be that difficult (at least for you...).
My arms block can be converted to palletizing robot arm - just rotate on 90deg plus add extra arm to constraint end effector to be perpendicular to the ground, then add rotation axis or ever leave as it.
Hi! Nice printer Why not going two arms instead of parallel arms? It seems to me a more elegant mechanism and more easy to be covered and hide arms, wires ,etcc How about tip dropping? Do you have to compensate XY or does it print OK in all printing area? Thank you so much! I am going to design a single arm scara printer in a couple of weeks cheers!
Two arms(canonical scara) or parallel (my) arms mechanically the same. (of course if i correctly understood your terminology)
You may drive second arm by belt or stepper placed on the end of first arm.
In case of stepper - it should be very strong, acceleration and speed will be decreased due to the mass.
In case of belt - i don't see problems, but parallel arms were chosen (as for me it is a little bit stronger)
I don't do any XY compensation. Print quality is enough for me, i use him as a my primary printer.
My printing area started from 50mm (in Y coords), but in coordinates less 50 i saw some problems.
