You have to remember PP is written for Tormach Machines which exclusively use inch ballscrews so in many places in the ui code this assumption is made. you'll have to fix them all
this is what i see on a cursory look at just the mill ui. really should check all python files, a grep could help there
is see reference in
ui_common.py as well
in the mill ui
these are places to check for where tormach may be correcting for the assumption the machine is in inches
some of these are snippets, i put ... at the end of each block if it is
Code:
def get_linear_scale(self):
"""Return the scale factor for all linear axes based on current G20/G21 mode"""
return 25.4 if self.g21 else 1.0
Code:
def on_touch_z_button_release_event(self, widget, data=None):
btn.ImageButton.unshift_button(widget)
valid, dro_val, error_msg = self.conversational.validate_z_touch_val(self.dro_list['touch_z_dro'])
if not valid:
self.error_handler.write(error_msg, ALARM_LEVEL_LOW)
return
ind = 2
# the G10 command wants values in mm if G21, but actual_postion and g5x_offsets are in machine units (in.)
# so we take the sup value and turn it into machine units, then send the offset command in g20/21 units
supplemental_offset = dro_val / self.get_axis_scale(ind)
tool_number = self.status.tool_in_spindle
...
Code:
def get_current_gcode_states(self, param):
outstr = '\n<span color="#003aff">'

for gc in active_gcodes:
if gc in 'G54G55G56G57G58G59': outstr += '<b>'+gc+'</b>'+' - current work offset\n'; continue
if gc == 'G20' : outstr += '<b>'+gc+'</b>'+' - machine in <b>inch</b> units\n'; continue
if gc == 'G21' : outstr += '<b>'+gc+'</b>'+' - machine in <b>metric</b> units\n'; g20 = 'mm'; continue
if gc == 'G90' : outstr += '<b>'+gc+'</b>'+' - distance mode <b>absolute</b>\n'; continue
...
Code:
def update_gui_unit_state(self):
is_metric = self.status.gcodes[linuxcnc.G_CODE_UNITS] == 210
if self.g21 == is_metric:
return
self.g21 = is_metric
# swap button art on jog step sizes
self.clear_jog_LEDs()
self.set_jog_LEDs()
# store off in redis for startup in same mode next time.
self.redis.hset('machine_prefs', 'g21', self.g21)
if self.g21:
self.dro_long_format = "%3.3f"
...
Code:
class Tormach_Mill_Gremlin(gremlinbase.Tormach_Gremlin_Base):
def __init__(self, ui, width, height):
gremlinbase.Tormach_Gremlin_Base.__init__(self, ui, width, height)
self.ui_view = 'p'
self.g21 = self.status.gcodes[linuxcnc.G_CODE_UNITS] == 210
if self.g21:
self.grid_size = (10.0/25.4)
else:
self.grid_size = 0.5
self.connect("button_press_event", self.on_gremlin_double_click)
Code:
def set_grid_size_small(self, widget):
size = (5/25.4) if self.ui.g21 else .1
self.set_grid_size(size)
self.ui.gremlin_options.update_grid_size('small')
def set_grid_size_med(self, widget):
size = (10/25.4) if self.ui.g21 else .5
self.set_grid_size(size)
self.ui.gremlin_options.update_grid_size('med')
def set_grid_size_large(self, widget):
size = (25/25.4) if self.ui.g21 else 1.0
self.set_grid_size(size)
self.ui.gremlin_options.update_grid_size('large')
you'll probably want to review all of these if you want to change the units in the ini file instead of the method used by tormach which assumes the machine is in inches
