Hi all,
I am experiencing some odd direction changes on a home-brew CNC
machine that I have on loan.
The machine was apparently purchased off ebay, and all the settings I
dug out from data sheets for the driver chips and motors.
X and Y are working well, but

Hi,
Under some circumstances this effect can be produced by one
motor winding connection not being good at the driver end of the motor
cable. Usually with a long (2 mtr) cable. Can also be due to one output of
the driver unit being bad. With power off, use an ohmmeter to check the

Not sure I agree about not needing EMC. I would like to use EMC (perhaps
more to the point AXIS) to load cad files and then generate gcode...
Riley, EMC does NOT generate gcode from CAD files - You have to use
CAM software for that purpose -
Thanks for the clarity. So in tutorials that I have watched / read how to.
I see AXIS load a DXF file then it passes gcode to emc which spits out step
dir?
What part is creating the gcode from cad files? Is this a function of
AXIS? Again sorry if this is a lame question.

What you're seeing is AXIS loading a G code file,
not a dxf file. There is no part of EMC2 that
creates G code fromCad files. Axis is just a GUI
for EMC2, which is a motion control
software. You need some kind of CAM software to
convert drawing files to G code.

Riley,
As mark said, EMC3 does not generate G-code from CAD files.
Axis is a display interface for EMC for the machine operator.
You need another program like pycam (see sourceforge.org) or cambam
(cambam.co.uk)
or others to load in CAD files like DXF or STL files, and generate
g-code

AXIS has the ability to run filters while loading files, so if someone
has a DXF to G-code converter, that can
A common ATmega8, e.g. in an Arduino board, is regularly used for gcode
interpretation on RepRaps and Makerbots. They can even load gcode from SD
cards.
However, I don't know if they are able to interpret [ ] or expressions,
or even loops.
Still, using axis as a gui might be beneficial, as if has
Stephen,
I agree, that EMC and associated software can do a GREAT DEAL more than
just interpret and display g-code, but Riley seems to be a 'rookie'

to understand the basics of EMC architecture and use. Knowing all the hooks
are there is great, but right now he appears to

Thanks for all the info! Great stuff. Stephen. You talked about Filters

Filters are programs that get a file name on the command
basically, they are called on command line level, and output some gcode on
the standard output stream, if I understand correctly.
There is also a second idea of having a filter menu, that gives calls

Thanks for all the suggestions.
No solution yet but a quick update...
The signal from the direction pin checked out ok on the multimeter so
it is definitely a hardware issue.
I have so far checked for bad connections leading up to the PCB and
off it to the motor and they are ok.
