#GECKO G540 4 AXIS STEPPER DRIVER DRIVERS#
With a breakout board and 1 or 2 stepper drivers If you don't want to control the spindle speed or use the charge pumpĪnother way is to add a second printerport or use a motion controller The 5V supplies negative terminal to the G540 common (terminal 12)Ī modified printer cable could enable the use of pins 14 & 16 for a 6th axis The -step to the G540 output1 and -direction to the G540 output 2 Its possible to use them to control a 5th axis for a rotary tableĬonnect a +5v supply to the + step & + direction to the external driver If you don't use the two G540 outputs to control relays ( G540 terminals 5 & 6 ) The remaining 2 outputs - pin14 connected to the PWM to 0-10V converter, pin 16 the charge pump The printerport has 12 outputs connected to the G540Ģ control the open drain outputs normally used to switch relays on and off (pins 1 & 17) It depends on what outputs from the G540 you are using now Will you just leave the g251 enabled all the time or is there a solution to that as well? Good luck with getting it working that way. I didn't realize the G540 had 2 digital outputs. A second parallel port will give you most of those things you mention even, just not fast and no analog. (at least for now)Yeah, I guess for $13 it's certainly worth a shot. I'm not sure I need the extra features provided by the mesa cards, but I'm just using *lowly* stepper drivers, no closed loop, no spindle control, no probes, etc. It seems the Mesa cards are a lot more purpose built, but I'm still having a hard time justifying it over a dual parallel port pci card that has been confirmed to work with linuxcnc and is like $13 shipped.
I went ahead and ordered a gecko g251x and hope to connect it to the open pins on my gecko g540 board (as several have suggested) and continue to use it as a "breakout board." After some more searching on other forums, there are several people who have experience with adding a few extra steppers to a g540 via various ways.
No spindle or laser or anything else using any other pins of the port. I perhaps should also add that at this point I don't really run much else besides endstops. Would a dual pci slot work? Is there an advantage or disadvantage to one? I could always use a newer computer and a dual pci slot. My other option would be to put a second parallel port in my available pci slot, thus running my gecko g540 with four drivers, and using a breakout board (perhaps like a c10) and one or two drivers (like a tb6600).īefore buying anything else, does this seem workable for linuxcnc? I know a lot of parallel port cards work poorly, so I'll need to be selective. My gecko g540 is connected and I'm using all four internal drives.įrom my reading, it appears it is *possible* to do some work and get a fifth driver working on a single pci slot. I currently have an itx intel motherboard with a working built-in parallel port running linuxcnc. My goal is to get a five axis setup working with my diy cnc, as a learning experience rather than a money-making machine (trying to keep it affordable and reuse what I have if possible).
