General Mach Discussion / Re: Threading cutting Tool path running incorrectly in Mach3 turn Version R3.043.066

« on: March 31, 2017, 06:35:41 AM »

Hi Rich
I finally got it working in fusion 360  by slowing down the feed rate to 200 mm/min   if the feed rate is set any higher than 200 then it does not make it back to ZO  also if you don't give it enough clearance it won't make it back to Z0  I'm not 100% sure but I think what the problem might be is that  my  Z axes  can't move quick enough so it arrives At the cut depth  then moves back to the start of the thread and starts cutting, the  faster  you set the feedrate  the worse the era gets

 thanks again for all your help regards Mark

Hi Rich I loaded version .062    ran it with the wizard  and fusion 360 same result as version .066  I was wondering whether you would be able to send me a copy of the post  processor you are using with fusion 360
 and a couple of simple threading programs that way I could load it into my machine and  see if it works on mine  I have sent a  email to Artsoft  they suggested that I load mach4  with a PMDX smart bobs  orpokey57CNCd25  motion controller  as they seem to think Mach3  had its limitations with threading.
 I will do that if I have to but at the moment my lathe   can be run in manual mode using Arduino  and encoder wheels which is being  control through a GECKO 540  parallel port  controller  using a port switch  so if I upgrade to ethernet I would need to use something that I could plug my encoders into  so I can run the lathe manually  I was thinking of using a Vital  motion controller,   I will go down this path if I can't get it working on Mach3
 regards Mark

Hi Rich Thanks for the reply this may sound like a strange question but as I have only recently got  my version of Mach3  I went to  the website  and  only the latest version   seemed to be available for download
 regards Mark

This is the code that fusion 360 generates a thought this might help but as I said earlier it doesn't matter whether I use the wizard or fusion 360 the end result is the same

General Mach Discussion / Threading cutting Tool path running incorrectly in Mach3 turn Version R3.043.066

« on: March 21, 2017, 02:53:38 AM »

I am running Mach3  turn  Version R3.043.066 everything works okay when I use a wizard or fusion 360 to generate a tool path the part turns out fine, but when I try to use the wizard or fusion 360 to create a thread it shows the tool path in the software and it looks fine, but when you hit run it moves down to the part waits for the indexing signal runs down the first path okay then retracts and moves about three quarters of the way back down the tool path then moves in to the part goes all the way back to Z0 cutting thread backwards then starts back down the tool path the end result is the last part of the thread is fine but where it drops back in on the way back is ruined because it is effectively cutting backwards as well as forwards I have tried everything that I can think of, looked at the forums but can't seem to find an answer your help would be much appreciated.  I have attached some photos of the  tool path before I run it and after I  run it and this is the code that is generated
