I may be able to avoid all of this by using the TTF Text option in cstep.
At
the moment, I would just like to engrave simple text in a straight
line. Can
cstep do this successfully?
Is it possible to install other fonts? If so, how?
Hi Luberth,
Are you planning to build-in an opto encoder feedback function for
exact,
no-error positioning?

Hi,
I have one:
Please, insert subroutine to activate plasma torch activating, before
start
moving. I don't knew all details about this operation, but I can find
and
proceed to you, but I assume you already knew.

Path optimizing
optimse the HPGL file so there is less useless penup movement
see basic program at http://www.luberth.com/java/vectorize/vectorize.html
Path planning
Read ahead in the HPGL file and do no rampdown/rampup
if the direction of new move is same
or do a percentage of rampdown/up if +/-90degrees
for smoother motion
Backlash compensation
Compensate the free play in nuts and spindle
Floppy.disk
When opening a HPGL drawing file from floppy and then run the program
isnt nice
Because reading from floppy is slow
If drive is A or B then copy file to harddisk and then run it
TTF
Making the TTF and Borland CHR stroked font working
Motor output
Not delay after motor output
But a delay that keeps track of time around output
So no time difference because of variable number of commands(lines
of code) around output
accelerate/deccelerate rampup/rampdown
i used a simple t=t+1 for accelaration
wich looks like ___/
would be better if this is an S curve
i think that would be smoother
so the hard edges are rounded
searching for examples (famous curves frequency example?) http://www-gap.dcs.st-and.ac.uk/~history/Java/Frequency.html
only did lowest possible technical school so need some time to understand
this
http://www.cs.uiowa.edu/~jones/step/highlevel.html
Assign a depth to HPGL pencolor
or assign a max. depth to PenDown and do that in N numeber of cycles
Multiple offsets to repeat a contour
Rasterto vector conversion
edge detection, thinning, tracing
dxf, dwg support
m g code support
vector select/edit/delete
change delayvals to feedrates/min
moveto field enter a xyz val => move to that xyz position
etc.
