¿ªÔÆÌåÓýOne other thing I would add to Jerry's suggestions.? Stay away from dedicated full CNC hardware solutions.? Once in you are 'in'.? Setting up a separate break out board with individual drivers allows you to make incremental changes rather than scrap an entire board because one driver fails.? It also allows you the choice to switch to other control systems. ? That's why I chose the MESA 7i92H instead of one of the MESA Ethernet c/w terminal strips etc.? If you decide to change from LinuxCNC to something else it's a more expensive operation to scrap things;? essentially you are starting over. ? With the PMDX-126 (way too expensive nowadays IMHO) you can use the Parallel port from a PC running either Windows or Linux for MACH or LCNC or some other CNC software. ?Or plug in an Ethernet Smooth Stepper or the MESA 7i92H for MACH or LCNC.? But you can also get a far east BoB for under $10.? ? In all cases your wiring for motors, switches fans, power supplies stays the same.? Only the source of the parallel port cable changes.? The BoB in the attached photo, with 12V-24V applied even supplies 0V-10V for Spindle Speed control. John ? From: [email protected] [mailto:[email protected]] On Behalf Of Jerry Trantow

I mentioned in a previous message not to let the Linux part of LinuxCNC get in the way. Once setup, you can treat?it as a g-code processor and not worry about Linux. The cost is free, so it's always good starting point. If you have a hackerspace nearby, there is probably someone versed in linuxCNC.? ? I run my router, lathe, mill with linuxCNC. I used machineKit/LinuxCNC to run my 3d printer for a short while before rolling back?to Marlin firmware. I have Tormach PathPilot that I intend to try on my lathe. I'm planning to convert a friend's plasma cutter to LinuxCNC this fall/winter and I can run a laser diode on my router. ? There is documentation available and good support(but not organized very well) via? and good but often outdated info on the wiki. ? ? On Mon, Jul 19, 2021 at 10:23 PM Tamra <tamrabrogdon@...> wrote:
