Hello,
I am struggling with my postprocessor to do some turning with Mach3.
I have generated a g-code with Solidcam and there is the G74 code. Mach3 does not accept this.
I do not understand the G81 code and I think that this is intended for drilling on the mill, not for drilling while turning.
This is the part in my .gpp file for turning;
@turn_drill
local string for for1 for2 for3
for1 = '2/2.0(P)'
for2 = '2/2.0(P*10)'
for3 = '5.0(P*1000)'
local numeric save_feed xc_new
gcode = 74
if drill_type eq drilling then
r = 0
q = abs(drill_lower_z + r)
endif
if drill_type eq peck then
r = r
q = (down_step)
endif
if drill_type <> tapping
{nb 'G'gcode, ' R'r }
{nb 'G'gcode, ' Z'drill_lower_z ' Q'q:for3}
if drill_type eq peck then
{' R0.'}
endif
if feed_unit eq css
{' F'feed }
else
{' F'feed:'5.0(p)' }
endif
else
gcode = 32
save_feed =feed
xc_new = 100-p_feed
feed = feed*xc_new/100
{ nb 'G'gcode ' Z'drill_lower_z}
if feed_unit eq css
{' F'feed }
else
{' F'feed:'5.0(p)' }
endif
;tbd.. check for a maximum of 10 mm mistake (BIG MISTAKE)
;!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
feed = save_feed
{nb 'M5'}
{nb 'G'gcode ' Z'drill_upper_z ' S'(spin*1.3):integer_def_f ' M4'}
if feed_unit eq css
{' F'feed }
else
{' F'feed:'5.0(p)' }
endif
endif
endp
Someone has been working at this, see the comment.
Can G81 be used for turning?
Any ideas how to solve this?? Please??
