Rayh,
the whole gauntry acts as a swivel :-}
It's all made of aluminium sheet 15 mm thick, 30 cm wide and 70 cm
height with two 80x80 beams of 122 cm long. If I remove one of the ball
screws I can move that side a few centimeters without applying too much
force.
I thought of adding a timing
Folks,
The FISL's program committee sees the EMC project with enthusiasm.
They are asking if anyone of the people in charge of this project
could attend the Forum. This year it will be held on April, but next
year it will be on June.
Is this the right list to ask that?

On Fri,
Hi RobThat sounds like it should work since the two motors will not bind against a rigid frame. You're right about those motors jumping whichever direction they please when you apply power. As long as you don't have to worry about loosing steps, both motors could be driven from the same set of
Couple of thoughts Jorge. First is how to manage building the machine base. I'm sure that you know that the parts of the machine that hold it together and allow it to move are what absorb the cutting forces and harmonics and allow it to cut accurately. The KT company built quite a business with
Rob,
I have a machine with 2 motors on the y axis. This is how I home both
motors together... I have a positive adjustable stop on both ends. This
is a bolt with lock nuts. When both ends of the axis are on these stops
the machine is aligned and in what I refer to as the Hard y zero. To

i use gecko drives with 10 micro steps and i don't know if i ever lost
a step or not. i would like to add encoders to the back of my double
shafted stepper motors. i would like emc to stop all motors and report
any lost steps. i definitely don't want emc to try to make up for the
There is atleast one person doing this.. Here is some light reading.

Greetings all;
Pursuant to my need to re-think how I use the PMDX-106 to control the
spindle's vsr controller, I had wired the vsr's output such that a run
enabled relay is at the output of the vsr, and the reversing relay was beyond
that.
Rather than switching the AC power relay to the vsr

That SKU-47158 schematic is conspicious by its incompleteness.
The arrows labeled A,B C are in fact interconnects to the brains of this
servo amp, and which are not shown.
Note that a bipolar driving waveform presented to C, referenced to that
