Who's using Path Pilot over and above Mach 3.
Who's using Path Pilot over and above Mach 3.
I have been running it since it became available, not one glitch or uncalled for move yet! Transition from Mach 3 was easy for a not so savvy computer guy, I really like it.........

I have two 1100's with pathpilot on one and Mach 3 still on the other.
Today I ran an old programme on Mach3 on my old machine and was thinking about just this subject.
One thing to consider is will pathpilot be installed on a series 3 stepper/board set up or the old set up?
I still have series one gear running and it is slow and noisy compared with my latest series 3 with pathpilot -
But I am not sure how a combination of the two would run - I know they are compatible, but I mean how noisy and fast they would run etc.
M3 is a ugly messy layout after pathpilot though.
All that said, M3 still works fine so I should not complain.

So - May I use your thread to ask a related question.
How well does Pathpilot run on a series one machine?

I'm still running Mach 3 on my 2011 Series II. It has served me well since day one, so I say "if it ain't broke, don't fix it".
You can buy GOOD PARTS or you can buy CHEAP PARTS, but you can't buy GOOD CHEAP PARTS.
I went to pp and the world hasn't ended. I can use my atc and it has only crashed once which is great. I think this was due to not properly shutting pp down and my z height info was lost.
I like the soft limits and the fact that Tormach will be trying to fix bugs quickly.
Yeah i plan on getting it SOON.
A few days ago we had one of our famous "power bump" outages, goes off for a second then comes back on, it did this in the middle of a 4 part machining job and it only made a slight blemish in one of the parts, I think due to the cutter travel stopping while the cutter was still coasting down. I rebooted the computer, restarted the same program after referencing and it ran fine, I am sure it was off slightly due to the referencing but it didnt show in the finished parts other than the one blemish! I did not reindicate the part, just ran it to see what would happen.
I had forgotten the soft limits, those are invaluable to me - "wrong way Corrigan" applies here ha!

I've got two machines (not Tormach) currently running Mach 3 that have homing and limit switches. I've restarted a part after rehoming with no visible indication of a problem. Well, if I go back far enough to make sure I am before the buffered commands in my SS. Anyway, Mach 3 has that capability as well and it works.
My main reason for asking about PP vs Mach 3 was to find out if there was any huge advantage to one over the other for a new machine. Mach 3 is very configurable and I have written several of my own macros and screen sets, but if PP is rock solid, configurable, and over all better I'ld consider it. Are there any short comings to PP? G or M codes it doesn't support fully? I notice that it lists its own post processor for partnered software products. Is that absolutely necessary or will it run standard Fanuc code? I seem to recall that there were some tweaks for post processors even for Mach 3 for Tormach in the past. One had to do with tool changes. I never understood the need for that by the way since the tool change macro in Mach 3 is easily configurable.
I am very aware of many of Mach 3's shortcomings by the way. That being said I routinely run several hundred thousand lines of code, have run a couple code files right at 1 million lines, and one that was 1.3 million.

The main thing I like about Path pilot is its ability to run unattended, I couldnt do that with Mach as I never knew when it would make an uncalled for move.......some users dont have this problem but I sure did..
There are a few things in the user interface that could stand some attention, but I think over time that will be cleared up.
mike sr
Those are some large programs! My parts take a max of 20 minutes and thats a large contour op.
So far its rock solid.......
One main screen does it all.....
It doesnt recognize a P code before a G81 or 83, it throws a warning that it doesnt recognize them and they will be ignored, the program runs fine though and the tapping cycles retain the delay in them, I usually set .5 to 1 second delay at the spindle reverse in my tapping cycles, it uses the delay in those cycles.The only other problem I had was if I set up a tapping op and used the transformation function it would throw an error on that, selecting all the holes in all the parts it works fine. This was right at the start and it may be fixed now with the newer releases.

PP has a couple really big one ups over mach 3, in my mind.
- Soft limits; this saves me so much time during setup of large parts. No more bumping into the limit switches and having to reref!
- Work envelope checks; you'll get a warning if a program will exceed travel limits, again a blessing for large parts.
- Much nicer looking and designed interface. It could use more work, but it's a big step up from mach.
- The tool table and work offset screens are simpler and easier to work with.
There are also, supposedly, a litany of improvements in the motion control scheme over mach3. I couldn't speak to that, and I can't honestly say I notice any difference, but there you are. Like you I never had any any real bad behavior from mach3. But enough people did/do that I know those were genuine complaints and it's nice knowing that PP is built on a more stable code base. I have very high confidence in the software not trashing my parts or machine.
I haven't noticed any real negative qualities from PP. I know some have complained that they can't use dropbox or whatever without getting a little hacky in order to access the linux desktop. I have no intention of connecting my controller to the internet for any reason, or using it for anything other then controlling the mill, so that's not a problem for me.
I think the interface and usability features are worth the cost of the upgrade alone. The technical improvements the MESA board and linux back end provide are probably worth it too even if you never see the difference. The perhaps more practical reason for upgrading is simply staying on Tormachs support; I don't know how much meaningful support they can provide for mach3, but they know PP inside and out.
You are the second person who said that. Mach 3 has soft limits and I have them programmed on both of my machines with homing switches. You can program them for machines without homing switches as well. You turn limits off, mechanically move to your home position. Set home. Turn limits back on. For the two with homing switches I just hit ref all and I am done, or I can go to the diagnostic screen and home individual axis.Soft limits; this saves me so much time during setup of large parts. No more bumping into the limit switches and having to reref!
On the two machines I have setup soft limits on I get that also.Work envelope checks; you'll get a warning if a program will exceed travel limits, again a blessing for large parts.
Well, most of the standard screens for Mach aren't very convenient, but I have modified all my screens eliminating stuff I don't need (like extra DROs) and increasing the size of the code window, and moving a lot of controls to the all pages page instead of just on the run page. I don't think I could do it all on a single page, but that is a nice idea. It would sure bye nice to have controls and diagnostics on one page, but it gets awfully crowded quick. I make liberal use of the free screen editor Klaus wrote for it.Much nicer looking and designed interface. It could use more work, but it's a big step up from mach.
That would be awesome. I do find the tool table with Mach 3 a bit cumbersome to work with. That right there would be a huge deal.The tool table and work offset screens are simpler and easier to work with.
Well, they ran their machines on Mach 3 for years so they should be pretty familiar with it.There are also, supposedly, a litany of improvements in the motion control scheme over mach3. I couldn't speak to that, and I can't honestly say I notice any difference, but there you are. Like you I never had any any real bad behavior from mach3.

I am thinking about some more machines and my path is yet undecided. (pun not intended)

One thing to consider with pathpilot/linuxcnc you can specify in gcode how close to follow the programmed path.
G64P.005 tell the machine to go as fast as it can but never deviate more than .005 from gcode.

As shipped, soft limits have been disabled on Tormach machines that come with Mach3 and Tormach froze the version to one from several years ago. The Tormach Mach3 install is locked so some of the configuration parameters can't be changed from within Mach3 but on request, Tormach will supply the password to unlock the configuration. Many users have also just installed a more recent generic version of Mach3 which works just fine for someone like you that already knows their way around Mach3 but beginners can quickly get themselves into trouble so a frozen version with locked configuration makes support for that sort of user much easier for Tormach.
Perhaps of more interest to would be the claim that the trajectory planner in PathPilot is reportedly much better than what was available in Mach3.
Go to to this page on Tormach's web site and download their White Paper on Pathpilot from their Technical Documents link:

It should give you a better idea of the benefits they see for PathPilot vs Mach3.
After hacking to 150ipm, gaining Linux access and dropbox. PathPilot is more than 2x better than Mach 3, and I may even stop saying bad things about my Tormach in my videos. I honestly feel like I have a new and RELIABLE machine.
When I went to PP I bought a new HDD and replaced the Mach3 HDD so that I could just swap back if it was not working out. To date I have not fired it back up on Mach3 even once. I highly doubt I ever will. The PP upgrade really is an upgrade, a major one. 100% of the odd un-commanded moves, etc that I had with Mach3 vanished, and I can now drop files directly to the machine over the network. The PP upgrade is a brilliant move on Tormach's part. To anyone thinking about upgrading but not sure, I highly recommend that you do it. If you have cold feet buy a second HDD like I did, unplug the old one and leave it sitting there in case you need to move back for any reason. FYI, I bought an SSD and my boot time from main power switch to refing all three axis is about 34 seconds.
