should lazycam standard let you generate g-code or is that restricted to pro?

thanks
had a quick look for a gcode list but obviously didnt look in the right spot. possible a few too many tasty ales

oh and i almost forgot. lazycam. it say i only have a demo version. do i have to purchase a separate licence for it or will the one i have for mach enable it? if so how? i copied the licence file into the lazycam directory and that didn't seem to work.

my board is a xylotex max is 30v i think. if i have problems with 12v i will have to go into the hip pocket again and get a 24v power supply with a few more amps. not a big deal i hope but would be nice to keep the 10a 12v one i already have.
i have been playing around with some small programs to get used to the system and have noticed that g53 doesnt call the machine co-ords but calls an incremental move. if this is true what g-code do you you to return the machine home at the end of a prog. in almost all other experience ive have ive used g54-6 g90x?y?z? to call the part offset at the start of the prog. then to return to home called
g53
g0 x0 y0 z0
ive found that g28 will do the same, is that the mach3 equivilent?

ah i see now. that sucks a little
i will just have to slow it down and hope then. do you know if i will have motor troubles if i only run 12v instead of 24v

so i guess that the 4 encoder inputs are for manual hand wheel inputs rather than position feedback?

thats about what i thought they are only $50us a piece which is about half  the nearest price i could find. want the run encoders too. not have with the open loop system ive got at the moment. have you had a go at making them or would you get off the shelf stuff?

General Mach Discussion / Re: Very basic question about tool diameter compensation

« on: August 12, 2008, 06:50:45 PM »

hi sid
i havent read all the posts on this topic so someone may have already explained this better but i have a reasonable understanding of cutter
compensation ie left or right.
basically it relates to cutter direction in relation to the programmed path. for G41 (left) the tool will CLIMB mill and for G42 (right) the tool will conventional mill
to put this clearer - if you want to cut the outside of a circle in a clockwise motion use G41
                                - if you want to cut the outside of a circle in an anticlockwise motion use G42
another way to look at it is if you look at the cutter as it cuts away from you , the cutter compensation will put the on either the left or the right of the programmed path. LEFT (G41) for left ect ect
as far as actually calling it up in mach3 i dont know yet. im a newby myself
hope i helped

it really doesnt matter yet as the machine is only a toy. i will soon have a new hafco hm45 to play with which will get setup properly.
any suggestions on stepper motors? i have been looking around but cant seem to get any good comparisons. was looking mainly at the one xylotex flog with there kits, 425oz. i havent had alot to do with electronics and am not sure if they are too big or not. the hm-45 have a table of 600x300x300 approx 1500w spindle motor mt3 spindle. is there a rule of thumb for this stuff?

  finally some sucess.
i re-installed it on top of its self and got the same result of nothing working.
i then tried the driver test again and got the same.
then i tried just clicking on the driver files to see where they were in the properties section and couldnt see anything out of order, while rerunning the driver test between each driver file i tried. the driver test kicked into life after i looked at the "specialdriver.exe" file. dont know if that is what brought it to life and i dont really care because i have full movement in all 3 axis's and at a much better rate than i expected. i am getting around 3000mm/min out of x and y 1500 out of z. rather fast when the travel is only 100x60x60. thanks for your help 
will talk again soon
