Support, not only potential issues, but the lack of available training and documentation provided by some of Mastercam's competitors is laughable.

2016?

Try closing down Mastercam completely as well and reopening. I have ran into the same scenario on less than desirable Mastercam computers. Opening back up fixed it for me, a few times. Also make sure your tool path doesn't leave a small floating chip, it will stay and on the retract it can cause a collision. Even if its a pixel sized piece of material left behind.

I can see sending the typical, ask your reseller for blatant post request. But, come on he asked for specific help. If that was always the response, this site would be as useful as off topic.

The forth topic, is tricky, I am assuming its a Haas from the unlock and lock codes A Haas does not need the lock and unlock codes for positional work. It will automatically unlock and then lock once the move is completed, as long as you started in a locked state. If you unlock the rotaries through M codes, then the only way to lock the rotaries is through M codes. However the current Haas post needs to have the unlock and lock codes active, so it puts in unlocks when you are using the rotary axes to feed. Then it locks once the tool path is finished. Personally I think it would be best to control the lock/unlocks through Misc Integers, and set only the tool paths that need the locks/unlocks in their respective tool path default settings. Another option would be to turn off the lock/unlocks and just put them in a manual entry before the start and at the end of full 4th and 5th axis tool path operations.

MP master has the M05 before the G91G28Z0. It really is the post to use for FANUC.

My average on mills is .005 on walls and .005 on floors. But it really depends on what tolerances I am trying to hold and what kind of feature. Surfacing vs Contouring etc.

I ALWAYS TYPE IN CAPS INSIDE OF MASTERCAM

A decent warm up program will cut that down considerably. Moving all axes and running the spindle at operating speeds. After a decent warm up you should see less than .0005. This is why I would set all my tools at the same warmed up condition when ever possible. Also having tools that run for awhile, run them close to the same rpms when possible.

YCM/Supermax Sharp Daewoo +1 on Feeler Haas DM??

The reasoning behind this is, there were 7 or so different pallet sizes and a variety of sub-plates, so a retract that was safe on one pallet/sub-plate may not be safe the next time the job was setup. Jobs were only reposted for process and revision changes. Operators would not use the probes and some horizontals didn't have them, so you would have to key in the variable for the pallet being used. I no longer program everyday, but I will keep the retract/variable idea in mind for future applications.

On a horizontal I prefer a full rapid retract in the Z when doing rotations, mainly because of different pallet sizes in use.

On super critical blend parts I would back up small diameter end mills .0005 to .001 high. Run a few features and check the blend and rerun. This is when I needed less than .0002 mismatch.

I have used them on large verticals, to hold fixtures to the table or large chucks of material. Put as many bolts through the vise halves as you can, its a lot of force. Really nice quality.

Magnetic parallel holders are awesome, ebay for 15/20 bones. 5 axis vise stops if you do a lot of vise work. One or two good sets of hard jaws. A few sets of aluminum and steel soft jaws.

Select just the stock model operation and toggle the tool path on and off, like you would a normal tool path. Most likely this is just what you are after. But, if you have created a Pmesh from the stock model, meaning you have created a solid from the stock model, put it on its own level and turn that level on and off. It can get pretty confusing if you don't have good organization with Pmesh solids and stock models. Gosh darn it you people type too fast.....

If I buy a .0005 indicator it will always be a Shars, they break the same as a name brand. But for .0001 test indicators, I have always used a Starrett with the long tip.

Doesn't X+ list the tools in the order they are used in Mastercam and not numerically?

The X9 MPL post does in fact have it, just confirmed.

The mpl post from the download section should have it.

Slit one corner of the nut and hold in the vise. Also helps to make a nut that is longer than standard, if your thread is long enough. Not the best, but for a quicky, she'll do. I usually prefer to make a threaded fixture to screw into and then put a nut on the back, if a 5c is not practical due to size.

I would set your WCS to TOP (A0/B0), then make your C/T Planes rotated as you need. Post up a file if you can. The trunnion Haas post is pretty solid out of the box.

Does the surface finish look the same on single axis linear cuts? Even the Ballmill groove looks less than desirable, a tooling or process change may help, but I think you have a machine problem. What is the model of the machine?
