  1. No dice. I switched to a different machine def and the z depths posted a 4 place decimal but the arc moves were split in 2 insted of 4 and no extra z moves were posted. In the above code I am milling a circle. Unfortunatly it's an old machine and stops at each quadrent so all arcs have to break at quadrent. I've tried changing control def tolerances,config,and even post settings with no effect to step down tolerance. Thanks for the help so far.

  2. I tried to change tolerance in the control definition to no avail. Heres a sample of the code.

    N140 G1G40Y16.8354

    N150 Z-.1983F10.

    N160 G41D26Y18.3354F30.

    N170 G3X-4.3354Y14.Z-.1984J-4.3354

    N180 X0.Y9.6646I4.3354

    N190 X4.3354Y14.J4.3354

    N200 X0.Y18.3354I-4.3354

    N210 G1G40Y16.8354Z-.1983

    I have to calculate a start position that forces a three place decimal. In this case 2.

    N140 G1G40Y16.8354

    N150 Z-.16F10.

    N160 G41D26Y18.3354F30.

    N170 G3X-4.3354Y14.J-4.3354

    N180 X0.Y9.6646I4.3354

    N190 X4.3354Y14.J4.3354

    N200 X0.Y18.3354I-4.3354

    N210 G1G40Y16.8354

    N220 Z-.26F10.

    This .0001 variance is messing with my code.

    Could this be a post issue? Seems to only do this in arc moves.

  3. I analized the contour and z for all lines is the same.If I go from 0 to -.935 step down is output to 4 place decimal and the .0001 varience is output in the arc move. If I start at .015 to

    -.935 steps are even and I get a 3 place and all is good. It seems is that if overall depth does not divide to a equal amout MC calculates the steps to a .0001 tolerence. For this machine +/- .0002 is the best I can do. Would like it to stay 3 place if possible.

  4. Simple 2d pocket. .05 step down,.01 finish cut. From 0 to -.395. Mastercam calculates the step down in even amounts but for some reason in larger arc moves it calculates a .0001 varience in the z depths that is being posted to my code as a three axis move. My machine is not capable of three axis moves and stops. Need to eliminate these z moves.

  5. use_pitch : 0 #0 = Use feed for tapping, 1 = Use pitch for tapping

    rigid_tap : 1 #0 = Floating tap output, 1 = Rigid tap output (suppress spindle output and output M29)

     

    This is what I have in my post,(mpmaster). Once you set the pitch of your tool in tool parameters

    feed will automaticly change when you change speed in your operation tool paremeter. IPR may be easier but I'm old and set in my ways.

  6. There is a switch in the post to switch from feed per rev to in per minute. This should switch yor f line from pitch to feed and get rid of g95. If I stop a program in the middle of a tapping cycle and try to restart without cancleing g95 my machine will not move. I stay in in per minute and and calculate my feed in tool library.

  7. Running X4 Mu2. When I try to create points or arcs below the construction plane,say z-2. they snap to z zero. I usually create points

    position,small arcs or arc center. Auto cursor detects x-y but not z. Will highlight at correct z depth but z does not move in ribbon bar. I figured out how to change construction plane for z manually but it used to do it auto in x3. Is there a setting for this?

  8. My boss has been asking me as well. Want's to know how much time I spent programming a part. Event log is only good for seven days. He's got me looking at parts I did months ago. The way I estimate programming time is by sorting part files by date last modified and guestimating between the end dates. Add the cycle time and hope it matches my time cards. Setup sheet has cycle time for each operation. How bought creation time as well? Is it possible?

  9. Looks like what I'm looking for. I plan on using only spade drills as much as possible. I'm using the mpmaster post I got off this site. I have modified it several times so I know a little bit abought post mods. Maybe MC could add this feature. Definetly what I'm looking for. Logging off for the holidays. More info would be great. Thanks.

  10. Running X4 mu2. Getting into running extended length spade drills. M3-M5 carbide self centering blades. Cat 50 hmc coolant through with chip blaster. First off I'm running a stubby spade drill for a 135 deg spot. I need to start drill slow to center then then full feed once I'm in. Could use some learning on spade drills. I'm not used to running drills at high surface feed. 250+ on dia. from .5 to 1.5. Need drill cycle to go slow full dia. then full feed with blaster. Drills cut great but I'm getting bell shaped holes and major drift. I do mostly gray cast but get some 4140 once and a while. Ellp Meee. Thanks.
