Pathpilot here has been a Godsend here, flawless from the beginning! As stated above, its well worth the change.One thing I have noticed is that the feedrate isnt constant, on a specific curve it appeared to stop three times while machining the curve, usually this will leave a mark in the finish but I didnt notice any marks? Maybe there is a setting for this I dont know??I really like it as it can be trusted to run while I do other things in the shop.There are still a few rough edges but I think over time those will be worked out.I am new to this forum, so hope I posted correctly. I've always used Mach 3, but decided to make the change to Pathpilot. I went for the new Tormach computer (controller) with software just so I'd get a seamless transition between operating systems.So far, it's been great, although Linus (Unix) is still a mystery to me. I had to give Tormach a call to find out how to transfer gcode files from my inside-the-house computer (with Fusion 360) to my shop computer. Not difficult—just different from Windows.
VistaCNC iMach III USB Control Pendants are truly Plug 'n Play devices! Support Mach3, Mach4, LinuxCNC, UCCNC, Machinekit. Work with parallel port controller, USB and Ethernet based controllers for metal, wood, plasma and foam cutting applications. 3 jogging modes: accurate Step, silky-smooth Velocity, and constant Continuous. New updates to Tormach’s PathPilot® CNC control software include an enhanced trajectory planner for faster cycle times, and a new visual conversational programming feature for intuitive, step-by-step template to quickly write G-code for milling and lathe sequences.
It has a nice, clean interface that I like, and the conversational modes work better than those of Mach 3.James (seatlanta). I will likely stay with Mach 3 untill I can no longer use it. At that point I will have to decide whether to go with Mach 4 or Pathpilot. The main thing I don't like about Pathpilot is that it requires a specific computer, which you have to purchase from Tormach. The only trouble that I have had with my machine has been the computer. Having to go to Tormach for computer support when something breaks on it instead of ordering a (cheap) part or computer from one of the many available vendors is a sticking point for me.

PathPilot has been installed successfully on computers not supplied by Tormach. Tormach was, early on, restricting support for PP to users with a Tormach controller, and may still be doing that (sensible, as an install on an unknown machine is difficult if not impossible to support). That aside, one can order the distribution disk and install on anything that will run LinuxCNC.

I have to check this out again but one glitch I ran into lately with Pathpilot is that I accidently entered the offset data for a tool into the wrong tool number position. When Pathpilot used that tool number it got a zero length for the tool since that slot was never set up with a tool. It happily went with a zero length tool and crashed the spindle into my work piece just before I was able to hit the emergency stop. I plan to follow up with Tormach about this potential problem. They are very responsive.

I freely admit it was my fault for programming the wrong tool number but IMHO it should not allow a zero length tool (other than the spindle) when running a program. A zero (or negative) tool length offset can be valid if your reference is other than the spindle nose. This isn't uncommon so I wouldn't expect them to change anything.There a discussion about best practices for tool offsets on the PathPilot forum on CNC Zone recently. One person mentioned that he initializes all of his tool offsets to 11.111 that way if he forgets to set up the tool all that happens is that the mill head goes up.You can write a g-code file to fill in the table. The P value is the tool number.eg: (credit kstrauss from the above mentioned thread)G10 L1 P96 Z11.1111G10 L1 P97 Z11.1111bob.
