Mach4 General Discussion / Re: Mach Motion Lathe Wizards Bug? Help.

Not sure what you're asking, but I ran the wizard took a screen shot, posted the code, opening the code in gcode editor and took another screen shot.

Weird, why would my code be off? I mean there's quite a few things off with the parting wizard. It doesn't post the correct tool number, doesn't post the correct feeds and speeds and doesn't peck.

My mach is the latest release as of a couple weeks ago.

Rhtuttle, thanks for trying. Any suggestions? I mean once I'm aware of all the bugs I can manually change them, but it makes it difficult if I go back and update the wizard as I'm want to do if I creeping up on some dimension or trying out a new sequence.

Oh also if you notice in the pictures I posted above for parting that setting a different offset for the tool doesn't change it in the gcode. I set T0314 but the parting wizard puts the tool as T0303.

I'm guessing you retro fitted that machine as well? If so why not home inside the servo too? That's what I did on Mori Lathe. My new servos has that option if you want to set it in it's own software. I'm guessing you would have done that if it was possible using the old servos?

I think though my limit switches on the Mori are pretty accurate, but I never bothered to test them because I always though that limit/homing switches weren'' that accurate. I always thought professional machines used an index on a linear scale or servo. I mean some do and some don't, I expect. Plus my machine is from 1978 who knows how worn those are.

The manuf. of the servos said I can enact the pulse index by setting it up in Mach to do it  for me. At the time I didn't know how to maybe I'll explore that now; making a one button startup routine.

Yeah, I originally had the tool changer working with an 8 position rotary switch and push button to activate the tool changes. Then when you people taught me about Modbus I just too the switch function out of my ladder program and now Mach sends those commands to the PLC. SO I can let the gcode change the tool, or type it in MDI or still use the rotary switch, but now the rotary switch now does a tool change in mach so it's changing the tool number in mach and moving it to the correct tool change position.

I'm really liking modbus and PLCs, when you realize how easy it is and how you can impliment PLCs with it, the possibilities are endless.

Almost picked up TWO Fadal 4020 VMCs yesterday!!! Auction, perfect condition, went for about $5K each, one 1992 and one 1998. Rigging and transport kept me from buying them. $4000 from LA to SF. or $3200 for one sooo.... I really need to buy a 15K trailer so I can just rent a truck and pick this stuff up myself. They had some OLD but Working perfectly Kitamura Mycenter 1's, could have got one for $50.00!! But again transport.

Here's a pic of the wizard entries and the resulting code for the messed up Parting Cycle. Also the pecking part doesn't work at all.

@overloaded, it's not an offset issue as it still drills to the correct depth, just takes forever(s) ;-). I'm not cancelling anything. This is straight from the wizards. I'm doing 3 different drill cycles and compile them all within the wizard.

Here's the code:

Oh and another bug, kind of. If I do multiple drill cycles in the same program only the first drill sequence moves the drill to the Z that was set in the wizards. After my carriage moves for a tool change to a different drill the carriage won't move back to the correct Z so it starts to peck drill about 2 inches in front of the part. It has the correct coordinates to drill to, but the starting Z is way off and other drills after that are that way too so I have to edit the gcode so as to not waste time having it drill air.

Found a ton of more bugs in Mach Motion Lathe Wizards.

The parting wizard crashed my tool, now I need another parting tool. No matter what you change the feedrate to it stays at 10 IPM and the RPM stays at what you have in the preferences, in my case 1800 RPMs.

And it locks up every so often. It also will get hung up and the settings won't change. So if you go to run a program and some of the gcode is not what you want and you go back to the wizard and change a value and update it, it doesn't update the Gcode when you generate it.

I'm not sure why Chad used a Y, but I've found that Mach can at least read a Y output on a PLC and X. If you can find an address in your PLC software for an internal bit, I never looked, then I'm sure it can be done. I'm sure it must be as a PLC using Modbus can be pretty robust if using internal commands.
