edgecam and a pacer router help!!!

[rally.sport]

Ok so everyone seems to have problems with writing posts it seems,
i have edgecam 10.5 and a pacer router and im trying to get a correct post. my problem seems to be the file output R numbers in it after a x then a y the the R comes up a correct post ive seen has x y then z no R's ive seen another post which had i and j codes but again no R's but i do not know if it worked.
the file with i and j came from a guy using one via edgecam i believe the xyz file is a delcam out put code which weve seen demonstrated and worked.
also the blknum only goes up to 9990 then 9999 for all other lines (steps of 10 on our machine) doesnt matter what i seem to do never changes
i dont have access to support from edgecam as the program came with the machine allready loaded onto the pc bought secondhand and as far as i can tell the licence was the outright type not with maintenance as we cant get the 10.75 upgrade to download.
any help? or anyone got a post?
thanks in advance

With everything you've written, I still have no idea about what the code should look like.

Samples....
It does this X Y Z
I need this X Y Z

Is the R on an Arc move? Some machines do Arcs with an R (Radius). You've really not given much info about what you need it to look like.

hi mike thanks for the reply
the lack of detail is down to the learning curve im on! im not a machine programmer until about 2 months ago when i bought our first cnc machine.
the machine controller is a program called XMC-E and has 2.5d g code facility or hpgl which is how we are bringing in our data.

what i have is the following all generated from same model same paths:

N210 X17.841 Y80.232R226.302 this code gives a correct type of cut but seems to be a poor quality ie not enough lines when on the XMCE display for the machine

N220 G17 X30.172 Y132.209 I-40.244 J-41.931 F2377.3 this code travels only in straight lines at cut level the i and js are cut at z clearance although it appears to ramp up to z clear the path is correct quality

ive tried the above without the G17 codes and no difference.

N110 X18.412 Y18.309 R0.826 this produced no vectors in job error message when loading i dont know why as it appears the same as above top when comapring complete code.

N100X67.287Y40.582Z-3.469F3000 this code came from a powermill file and works fine every line has all the co ordinates in it.

when changing settings i cannot find what makes the R or the I J co ordinates change between them on the output it seems that the tick boxes in the modal section do not effect it likewise the machine settings for helical arc and arc plane do not seem to make this change.

Answers i need today after playing with the machine and 20 different codes i generated in my evenings are:
in machine setup the arc plane has several settings from none to xy+zy+zx what do the different settings achieve/do? i realise that the G17 code came from this box and thats how i tried it without.
the helical arc settings of none,single multi what are they for?
resolved rapids?
rapid 3d?
what setting changes between the R and the IJ code line output for the arcs?
is it possible to get a x... y... z... output on all lines from edgecam as per the powermill file?
lastly i can only get to n9990 then n9999 for all the remaining lines tried to change block numbers and nc file general settings but no difference.


thanks in advance to any answers and help from all users.

oh yes the other thing i forgot to mention with the first line in my previouse post the r codes produced a stepped curve not a smooth one but i havent checked it again with other generated paths as it was the first one i cannot be sure about the finishing quality set in the defaults the i and js were smooth but at z clear.

[rally.sport]

ok ive had a chance this evening to try some more.
the item im doing is best described as like a letter P a straight edge then a curve to a point.
it seems that all R codes for arcs come out staggered on the arc not smooth despite changing user setttings and the path is generally poor quality.
with the ij codes it seems that the lift to z clear happens changing the links from ramp stay at depth or optimised only changeds a stop and lift to z clear or a ramp to z clear during the arc.
ideally i think i need to make the ij arcs path stay at the xy level after the straight move.
all of the curves look fine when viewed in the ec system its only when loaded in via XMC-E
thanks

Does this machine do arcs?
What post are you editing (cgd file)?
Are you using the Wizard to edit the post?

It sounds like you saying the machine only does linear moves.

What is the geometry your cutting?

If it's a spline curve, the outout could be for a million small arcs. But there should also be a G02/G03 for the arc command.

hi mike

yes i believe the machine can do arc's it uses xmce software which has 2, 2.5 and 3d input/config modes but my version only has 2 and 2.5d according to the manual it will import g code or hpgl for 3d work within this 2.5 setting but offers no inbuilt modification to the path suits me as im using ec for that bit.
the display sees the arc and the machine moves the ij arc fine but a z clear with the r mode it sees a stepped edge and moves a short edge but stays at depth.
for a post ive tried using and modifying a fanuc bases and a iso generic bases and also one from scratch with the wizard it seems that any of them produce a similar g code path but the pacer machine makes the same mistakes on any of these posts.
its a surface geometry but ive tried turning it into a solid and got the same resulting problems so i can eliminate that

another oddity ive found is the mill by region setting when roughing then profiling it roughs by region but the profile cut did one pocket complete then the main p shape and 2 more pockets were done one layer at a time both in the player module and the actual job being free run

Good day

Does anyone know how to change the edgecam sample lathe to the machine that you are using, example to a siemens lathe?
