Re: Returning to MACH3/4 from LinuxCNC
|
Fanuc 21 firmware has been out since 2010 ish - any was just a development due to hardware changes of software/firmware that had been out for many years.? Bugs were eradicated years ago and there has been no need to improve on it since. If it ain't broke it don't need fixing.... ? My original reply was LinuxCNC related.?
Pathpilot is a commercial Tormach product and is also neither Mach3 or LinuxCNC. It is a Linux based system, as are Fanuc controllers.?
Pathpilot was developed because neither Mach3 or LinuxCNC did what Tormach wanted, so they took the open source HAL from LinuxCNC as a basis for their own work. To counteract any licencing issues they had to release their software but cleverly limited it to some custom Mesa style boards made specifically for themselves. I seem to remember they also bought out the company that made the boards to protect against clones.

I have no experience with Fanuc 21 controllers but I’ve never encountered any bug free software after over fifty years of computer usage. Congratulations! ? I’m sure that you understand why Tormach doesn’t exactly make an effort to ensure that you can use their free software on non-Tormach machines. On the other hand PathPilot runs on most any reasonably modern cheap PC and touch screen with no need to find an XT machine with a parallel port. ? BTW, the original question was regarding Mach3 and LinuxCNC rather than Fanuc controllers. ? ? From: mach1mach2cnc@... [mailto:mach1mach2cnc@...]

Subject: RE: [mach1mach2cnc] Returning to MACH3/4 from LinuxCNC ? ? John Stevenson and I did look at Pathpilot when it first came out. At the same time we obtained a couple of stand alone panel mounted clone Fanuc 21 style lathe controllers. It took me little longer than a week to get one of the clone controls wired and working fully closed loop. It's still working now, never needed any bugs fixing as it didn't have any. It has the great advantage of NOT using pc hardware or cluttering the shop with a keyboard or mouse. Pathpilot looks very pretty but was an utter bastard to get it to work with non tormach hardware and we never fully sorted it. It was quickly abandoned to the trash and forgotten about until now.? As Dan noted - quite easy to piss off the Linux guru's - any criticism is taken as if you called their mother or granny a whore LOL? On 22/09/2019 18:09:02, 'Ken Strauss' ken.strauss@... [mach1mach2cnc] ? I used Mach3 for several years on my Tormach PCNC770. When Tormach released PathPilot (which is mostly LinuxCNC) 3 years ago I converted. There is absolutely no comparison between the two types of control software.. LinuxCNC hasn’t crashed or randomly done funny things over the last 3 years, the user interface is very attractive with clean elements instead of the gaudy default colours of Mach3, touch screen operation is a delight, the tool table works reliably, soft limits work, I can transfer files to my machine over Ethernet and even surf the net while running a job, the GCode dialect supports named variables and conditional execution which is great for hand written code but most importantly bugs are fixed with updated releases several times a year rather than being ignored. In summary, I would even consider going back to Mach3. ? From: mach1mach2cnc@... [mailto:mach1mach2cnc@...]

Subject: Re: [mach1mach2cnc] Returning to MACH3/4 from LinuxCNC ? ? Hi John - It's some years ago now but I gave it a good test but gave up. I'm not a programmer or software developer or any other sort of guru so failed to get it to work reliably. Unless you know Linux really well - forget it. It seems to have been written by some clever people but for specific instances and hardware and if your machine or method of working didn't exactly match you were on your own and expected to modify or amend to suit yourself. The GUI interfaces were mostly appallingly bad too. A quick look a few minutes ago shows nothing much appears to have changed in years LOL... On 21/09/2019 01:13:13, 'John Dammeyer' johnd@...
