attched is a proposed schematic for 5 axis using 2 bob controller,with the use of 2 x axis drive motors. Is mach3 - 4? currently supporting more than 5 axis? Im looking for 5 axis screen set for mach or another application that support more 5 axis?

thanks.

Mach3 supports 6 axis plus a step/dir spindle.
There's a 6 axis screen here, and possibly one or two more 5 axis screens in the MAch forum.

You have 6 axis in your schematic?
In order to use 7 motors like that, you won't be able to slave the X motors. But you can drive the 2 motors by splitting a step and dir signal.

thanks ger
I figured that... may be in that case, what other cam software support 7-8 axis
I may want include a lathe in the future.

Thanks

anyone here in the zone, have any luck building a work robotic arm
like this one

doesnt seem that hard if your have a good mill or good cnc router to fab your
parts?... anyone know of anyplans on the net for ref?

I found this video showing the some of the working interior of a smaller articulated arm.

I inquired with brian today about the kinematics module, he told me its in the works for mach4 , some time after the dust settles after the big release.
FYI Im the mean time ecm has a kinematics suport.

Has anyone see a source for aluminum indexer circular base (3"-4" diameter) the housing should be made of aluminum? That is simular to the joint in the above video of the articulating arms. The ones i seen are small steel square base 3"x3"x2" and very heavy for the B C axis on a arm.

Thanks

I know you have already read about this in the robot arm thread - but emc2 already has kins support for robot arms. (very flexible...)

Thanks , for posting the welding video, as noted in post 7 mach will have support in in the near future, for now emc is the only way... unless there
huge suport for it.

This arm is simular to my idea i had, use a couple of rotatary platters for the waist and shoulder and elbow joints
I would add another joint for wrist joint ( seen in video 3). Anyone know how axis emc supports? In there current release?


Just looking at this video (2), this arm looks simpler to fabricate than a large 5x12 with 5 axis gantry machine, also less material for the table top.


other inspiring designs for arms

Mach3 V4 was supposed to be released 3 years ago, so the near future may not be as near as you think.

I wasn't going to say anything ....

another 5 axis schematic using a single bob

This drawing for ref only!!!! other bobs and vendors may better suited.... ( having optical isolatation and more features)
this drawing is only intended for educational purposes.... use at your own risk!

that why the comment was made to use emc.... in post #7
read between the lines... lol

Eloid,
What BOB u use? Do you have pmdx 126 schematic for 5 axis? or just replace your BOB on drawing with pmdx 126? I have this pmdx 126, its 4 axis.
