My MaxNC kicked the bucket again so I'm looking for a cheaper solution than replacing their drive board and dead motors which I've done once. ?Two options I can think of are using small hydraulic motors that won't burn out when overloaded or some other maler's drive products. ?Any leads? ?Any advice on how to make my own hydraulic system? ?I can hook up chips to drive a proportional hydraulic valve to a Raspberry Pi but I know too little about position sensors and the software to make G-Codes work. ?Thank you. When I send this message it says sent but it doesn't show up in the group display, so I'm thinking my rural ISP may be eating my posts. ?Sorry if duplicates appear - I do want an answer. ?Thanks. |

开云体育Hi: ?? Adding Hydraulics to a maxNC would be like adding rocket boosters to a 1960 red rocket wagon. I think what you really want is either better stepper drives, or a 3 axis servo system to run it. It may just be your drivers, they weren't very good originally, some had wave steppers, others a "kinda" servo system. Check into a Gecko G540 or similar device. A G540 could basically replace your entire drive electronics in one fell swoop if you have steppers.? Going any higher level for a MaxNC would require thinking about replacing the MaxNC altogether.. With the G540 you can drive it from LinuxNC or Mach3 from a printer port, or if you have 64 bit windows you could get a Pokeys or similar device to drive the G540.. I doubt you'd ever have to replace it again... ?Two cents.. for what 2 cents are worth in Canada at the moment.. Art ? ? On 7/9/2016 12:06 PM, maxnc15@...

Art, Thank you. ?I see the G540 is a bit cheaper on Ebay.? Kirk ---In CAD_CAM_EDM_DRO@..., <fenerty@...> wrote : Hi: ??

开云体育Exactly.Use 2M542 or similar drives, for 1. no-back emf, 2. soft start, 3. ability to use differential signals, 4. ability to disable single drives 5. less noise Vs gecko 251s or g540. Oh, they are cheaper as well, but thats less important. 542 series is around 40-50$ / drive, use 48V DC. On 09/07/2016 19:05, 'Andy Wander'
