Yes you are correct.
First you copy the file our_kins.c to src/emc/kinematics/
Then you change the Makefile:
- look for rotatekins somewhere towards the end of the file and add the
following
obj-m += our_kins.o
our_kins-objs := emc/kinematics/our_kins.o
This will look for src/emc/kinematics/ou

'comp' is the tool for compiling HAL components that are implemented in
a single .c file. Kinematics modules are one kind of HAL component.
If you are using the package version, install emc2-dev and
build-essential packages using Package Manager or the commandline.
Then, use 'comp' to compile an

the driver has not been updated for 4 vs. 8-axis HOSTMOT.
Likewise it would be nice

Chris,
Thanks for the info. I'll give the filtered PWM option a try. I'm in the process
of hooking up the spindle encoder at the moment so will soon see what resolution
it's got. I can see from the wiring diagram that it's A & B quad and index but
I've no idea what resolution. The axis motors all
Peter, Anders
In my case 8 axis support in the driver would be nice for the next project I'm
working on (conversion of a Wessel CNC router to EMC control + AC Servos +
Perske spindle) although for the VMC I'm retrofitting at the moment I need all
the IO I can get. The IO for the toolchanger is lo

Thanks for your comments Andy but I can't see anything wrong in my ini
file and still can't understand what is going on. The problem I was
describing of not being able to reliably set zero home positions occurs
when I first switch the machines on. For instance, I just turned on to
set up a new
Take a look in the .var file you are running. Variable 5220 should be 1
and the rest zero unless you are trying to preserve some offsets.

If Eagle can import the gerber file and convert it to an Eagle board the
n the trace isolation gcode from an Eagle board program is already done.
I'' look later tonight to see if Eagle will import the gerber files or
if a User Language Program is needed and/or available. I've never needed
to tr
There are a bunch of different things that affect the relationship
between machine coordinates and gcode coordinates.
"G5x coordinate systems":
At any time, one G5x coordinate system is in effect. Normally the
G54 coordinate is in effect at emc startup and after readahead
reaches M2.

I notice on stepper charts for speed vs torque that the bigger the motor the
lower the
RPM at max. Looking at the Nema 23 STP-Mtr-23079 from Automation Direct the
Chart stops at 1350 RPM.
