I have created a new feature-branch that supports up to 8 spindles. Spindle-synched moves such as threading and feed-per-rev can be synched with any spindle. The readme file for a sample config in the feature branch is here; https://github.com/LinuxCNC/linuxcnc/tree/andypugh/JA14_multispindle/conf

Old multi-spindle mills were used to cut multiple identical copies, usually with a hydraulic tracer running on a pattern. For that kind of use the code wouldn't need to be any different. Just load your 2+ workpieces then run the machine. Another multi spindle machine that was used before CNC was

We several multi spindle wood carving routers already running Linuxcnc. It was not hard to set up a little hal logic to enable/disable the spndle(s) you want to use. I set up a few custom M-codes, for it. Works like a charm. Big heavy duty multi spindle woodworking machines used to be much mo

we have a "lathe" at work that has a spindle that uses "S" codes and a rotary "C" axis. The rotary axis often is used as a spindle. The spindle feeds on Z and the C axis is mounted on X. But I suppose that's not what you are asking about. On Tue, May 24, 2016 at 4:59 PM, andy pugh wrote: > Has

I would enjoy, given the opportunity, attempting to set up LCNC on a turning center with a main spindle, subspindle, and multiple turrets. These are very efficient machines for making turned parts (and generally have live tooling as well). I believe one typical way of controlling these is with a s

In my case no as only one spindle is being used at a time. I assume for multi-spindle routers where they are making several copies of the same part that one speed for all is OK. JT On 5/24/2016 4:19 PM, andy pugh wrote: > On 24 May 2016 at 22:07, John Thornton wrote: >> I've seen some talk ab

I've seen some talk about multi-spindle routers and I'm fixing to start working on one. The main thing is being able to turn the spindles off and on as needed. The last one I did I used digital out IIRC. JT On 5/24/2016 3:59 PM, andy pugh wrote: > Has anyone here ever wanted multi-spindle supp
