Hi to all,
I am in the process of retro'ing a Cincinatti talon lathe.I had the machine up and moving with a Delta tau system,and the pmac died.Enough...
I am using a Mesa 5i20 and 7333ta for the motion part.I have a bunch of get started questions.
How do I tell this thing its a lathe?What axis is the spindle considered?
The Mesa uses a driver and pinout(hostmot 2).In what order does this stuff get loaded.Is the pin out for each application as simple as the .pin examples?Does this get complied?Whats the basic steps to get it loaded?
DT used a C type system to address i/o. A bit is defined ,ie, x:$000d4,then an M variable is pointed at it,M835,the an a macro name is pointed at that, CR_ESTOP,so when you wanted to address or read that bit you used the name.You made a header file and used those address's to write your logic.
#define CR_Estop M835
m835 ->$ x:000d4
How are the available i/o bits accessed in EMC,ive looked at several Hal files and it seems as if i/o points are just made on the fly.Am I making this harder then it is?How does it work?Can I define an input 4 bits wide,say for a BCD turret encoder?
is there any way to avoid the ladder programming for plc stuff and use text base?Like I said,I put a considerable amount of time in on DT,Im used to something like this.
if(cs_control_reset=0 and estop_prev=1) and (cr_estop=1)//no estop
CR_machine_elec=1 //power relay board
cr_amp_enable =1 //power to drive
cr_hydr_pump=1 //power hydraulics
endif
I would also expect the user units for each axis to be:
(ppr x 4)x(pitch of the screw) ie (2500x4)x(25.4/8)
2500ppr x the decode x an 8mm pitch.Several of the example files didnt use the decode.How is a single ended DAC handled by mesa and Emc?
I know some of this stuff sounds dumb,but Im new to this.Any help anyone can share would go along way.Thanks ahead of time.
