Hi All, Thank you for the tips. I am no expert in post writing. I appreciate the feed back. I will edit my post and give it a go after the Christmas break. We have shut the machines down today for the year. I wish all of you a Merry Christmas and I will let you all know the outcome. Cheers Dave

Hi Metal Slinger This is an extract from my UMC post. You need to add your M73 and M74 here before you can do anything. This will output through tool air by using the Coolant 4 seletion in your coolant selection dropdowns inside you operation parameter page. # -------------------------------------------------------------------------- # Coolant output code selection for X style coolant # Note: To enable X style coolant, click on the General Machine Parameters icon # in the Machine Definition Manager, Coolant tab, disable first check box # Output of X style coolant commands in this post is controlled by pcan, pcan1, & pcan2 scool50 : "M8" #Coolant 1 on value scool51 : "M9" #Coolant 1 off value scool52 : "M83" #Coolant 2 on value scool53 : "M84" #Coolant 2 off value scool54 : "M88" #Coolant 3 on value scool55 : "M89" #Coolant 3 off value scool56 : "M73" #Coolant 4 on value scool57 : "M74" #Coolant 4 off value scool58 : "M8(Coolant5=ON)" #Coolant 5 on value scool59 : "M9(Coolant5=OFF)" #Coolant 5 off value scool60 : "M8(Coolant6=ON)" #Coolant 6 on value scool61 : "M9(Coolant6=OFF)" #Coolant 6 off value

Hi All, I have written a macro for my control to hone bores using a flex - hone. Due to the flimsy nature of these tools it is generally a good idea to only start the spindle once the flex-hone is partially in the hole to avoid whipping. The spindle on M3 command is embedded in my controls macro . In order to use my macro as a drill cycle, I have setup a custom cycle (9). This is working perfectly, however, in the tool change area of my post I am wanting to stop the output of the spindle command for drillcyc$ 9 " only ". OK so from my code below here is what is happening. If I have drillcyc$9 (my honing cycle) in my operations, I am indeed getting no spindle output which is what I want, however, I am getting no spindle output for any other operations either including a standard 2d contour. If I am using any other drill cycle I am getting the spindle output as required both in drill cycles and standard contours etc.. I have tried a few things, but I am at a loss now. I can't seem to force the spindle back on if I am using my custom drill cycle. Thanks in advance for looking at this. # -------------------------------------------------------------------------- # Start of File and Toolchange Setup # -------------------------------------------------------------------------- p_goto_strt_tl #Make the tool start up at toolchange pfd_shft_inc psign_ang_out ##### Custom changes allowed below ##### #Unlock rotary axis if use_clamp, [ p_lock = zero s_lock = zero pbld, n$, s_slock, e$ pbld, n$, s_plock, e$ ] if stagetool <= one, pbld, n$, *t$, "M6", e$ if n_tpln_mch > m_one, #Toolplane mapping mode [ #Enter your mapping scheme here... pg68_map pbld, n$, "G43", *tlngno$, *zabs_s, e$ pbld, n$, *sg00, pwcs, "X0.", "Y0.", *zabs_s, e$ pcan1, pbld, n$, *sgcode, *xabs_s, *yabs_s, *p_out, *s_out, strcantext, e$ ] else, #5 axis and regular mode ( n_tpln_mch = -2) [ if cut_ra_head & use_g45, #Swap xout and yout based on offset axis [ tloffno2 = tlngno$ + g45_of_add n$, sg28, "Z66.386", e$ pcan1, pbld, n$, *sgcode, pwcs, *sg254, *sgabsinc, *yout, *p_out, *s_out, *speed, *spindle, pgear, strcantext, e$ pbld, n$, "G45", *tloffno2, *xout, e$ ] else, #HONING ONLY [ if drillcyc$ = 9, #NO SPINDLE OUT FOR HONING [ n$, sg28, "Z66.386", e$ pcan1, pbld, n$, *sgcode, pwcs, *sg254, *sgabsinc, *p_out, *s_out, *speed, pgear, strcantext, e$ *sg254, *xout, *yout, e$ ] else, #OUTPUT SPINDLE FOR ALL OTHER DRILLCYCLES [ if drillcyc$ <> 9, #OUTPUT SPINDLE FOR ALL OTHER DRILLCYCLES [ n$, sg28, "Z66.386", e$ pcan1, pbld, n$, *sgcode, pwcs, *sg254, *sgabsinc, *p_out, *s_out, *speed, *spindle, pgear, strcantext, e$ *sg254, *xout, *yout, e$ ] else, [ if opcode$ <> 3, "OUTPUT SPINDLE FOR ALL OTHER TOOLPATH TYPES n$, sg28, "Z66.386", e$ pcan1, pbld, n$, *sgcode, pwcs, *sg254, *sgabsinc, *xout, *yout, *p_out, *s_out, *speed, *spindle, pgear, strcantext, e$ ] else, [ n$, sg28, "Z66.386", e$ pcan1, pbld, n$, *sgcode, pwcs, *sg254, *sgabsinc, *p_out, *s_out, *speed, *spindle, pgear, strcantext, e$ *sg254, *xout, *yout, e$ ] ] ] ] if stagetool = one, pbld, n$, *next_tool$, e$ #Lock rotary axis if use_clamp & (cuttype = zero | opcode$ = three | opcode$ = 16), [ p_lock = one s_lock = one pbld, n$, s_slock, e$ pbld, n$, s_plock, e$ ] if n_tpln_mch > m_one, #Toolplane mapping mode [ #Enter your mapping scheme here... pg68 pbld, n$, *xout, *yout, *zout, pscool, e$ ] else, pbld, n$, "G43", *tlngno$, *zout, pscool, e$ ##### Stop custom changes #####
