Background: Knee mill with quill locked so Z Home is with knee all the way down. Using PSNG tab with VERS.GE Touch Probe and AliExpress Tool Setter. Didn't like using Tool Setter for each tool change regardless of length in tool table and the Alkabal code uses tool table length to determine if a tool measurement is required. If tool length is 0.0000 then use the Tool Setter otherwise use the preset length in the table. Now using : Measure_toolsetter_inch.ngc from Alkabal to determine Tool Setter height. Inside .INI file: # Alkabal Version REMAP=M6 modalgroup=6 ngc=m6remap # Original Version # REMAP=M6 modalgroup=6 prolog=change_prolog ngc=psng_manual_change epilog=change_epilog # ---- PSNG end ---- # # end Touch Probe Also in the .INI file determined by using 1-2-3 blocks and surface of table and feeler gauges # begin Touch Probe [PROBE_SCREEN] # Absolute distance from table to bottom of spindle WORK_HEIGHT = 12.703 [PROBE] LENGTH = 3.162 [TOOLSENSOR] # Absolute distance of top of tool setter when light comes on. SETTER_HEIGHT = 3.6631 I have to double check but I don't believe the Alkabal software is using the SETTER_HEIGHT value. Instead it stores: WORK_HEIGHT minus "Tool Setter touched with spindle bottom" value into the G59.3 Z location which is -9.0399 determined from the Measure_toolsetter_inch.ngc Now T1 is my spot drill with a length of 2.91819 in the tool table and after a tool change to T1 the G54.Z offset is -10.7147 The T5 is a zero length too and I left the T1 spot drill in place for the tool change after which the tool setter probe resulted in the G54.Z offset set to -7.8167 In both cases the tip of the spot drill brushes the top of the 1-2-3 block set as a 2" point above the table. So there's another variable in play somewhere. Not sure what yet.
