CNC lathe Multi Channel

Hi...Is there any way to do multi channel machining in linuxcnc?
I would like to have 2 independent cutters that would follow same toolpath but with a space between them where tool2 would do same motion as tool1 but 2 inches later than tool 1 , following same profile...I think i have seen something like that before but I do not know how it was done.

Thanks for any help!!!,

Rick

Lcnc support single-channel only. Unless you have the means to have two instances running and synchronized by a wait-server, then it 'could' be done.

To this day the cheapest way to build a multi-channel turning machine-tool is to use a Sinumerik 828D-T with the added M-C license (roughly $9k). S120 drives, servos and cabling are additional. All together you're looking at a $20~25k (minimum) investment.

Turn. Correct. Requires sync, starting at the CAM/kin post-processing...

I copied this from a previous question that seems similar....does the partial answer i pasted below seem appropriate for my desired use?...

Thanks!!

If you want to control them independently and simultaneously in g-code you will need to have a axis letter assigned for each degree of freedom you intend to control in g-code. Possibilities would be XYZABCUVW and you would be limited to those 9 in g-code. So if you are wanting to have your multiple Z and C axis do different things at the same time you are going to have to use the drive letters. Where things get grey are if you don't need simultaneous independent control. Then you can do things with changing which joints are slaved to what axis letters, but this will add an order of magnitude of complexity to your machine configuration. So if your multiple Z and C axis are either doing the same thing together (slaved) or not simultaneously, then you could possibly use Z1, Z2... and be changing which joint is obeying the axis command using M-codes.

Using additional axis letters will only let you run different tool paths by running them sequentially (ie you would have to wait for one to finish until you could start the other). If that is all you need then it may do what you want but that is not multi-channel use.
Multi-channel controllers can run different toolpaths in parallel, basically like running two machines at the same time with the added benefit of being able to synchronize the two to avoid conflicts.
