A general question on using two motors in this situation. I'm using steppers, so I'll frame the question for them.
Assuming identical motors and driver boards, is it possible to wire both driver boards to the same output from the breakout board. Example: run the wires from the BOB X-axis step pin to the step input for 2 drivers and the X-axis direction pin to dir input on both drivers? Power, watch dog, etc. wired as necessary for safe operation. 2nd question: Is there a glossary/dictionary of terms/acronyms used regularly on this list. I have a hard time figuring some of them out. I'm thinking of LCNC/machining terms, specifically. TIA Raymond Julian Kettle River, MN The things we admire in men, kindness and generosity, openness, honesty, understanding and feeling are the concomitants of failure in our system. And those traits we detest, sharpness, greed, acquisitiveness, meanness, egotism and self-interest are the traits of success. And while men admire the quality of the first they love the produce of the second. -John Steinbeck, novelist, Nobel laureate (1902-1968) On 06/12/2014 03:42 PM, Viesturs Lācis wrote: > 2014-06-12 16:52 GMT+03:00 Todd Zuercher > <zuerc...@embarqmail.com>: >> I don't really have a good reason, more exploring options and thinking out >> loud, not really wanting to fight with the problems with gantries in >> LinuxCNC, > > Well, I do not see much issues with LinuxCNC regarding gantry machines. > So far (up to 2.5.4) there have been 2 things to watch out for: > 1) machine would remain in joint mode, if MDI command is executed > through halui from pyvcp button (this affects any machine with > nontrivial kinematics);. > 2) operator has to remember to switch to world mode after homing all > joints, otherwise jogging machine will cause jogging just one side of > gantry.. > > First one is fixed in 2.6 branch. > Second one is fixed by something like 30 minute (including dowloading > source code from git) setup routine - start by adding few lines to > Axis script to create hal pin in Axis GUI that switches to world mode, > then connect it to axis.n.homed pins through and4 module (created by > customizing and2 module). > > I do not know of any other gantry-related issues (just spent another 5 > hours with my gantry router and making some chips, LinuxCNC works just > wonderfully). > > Viesturs > > ------------------------------------------------------------------------------ > HPCC Systems Open Source Big Data Platform from LexisNexis Risk Solutions > Find What Matters Most in Your Big Data with HPCC Systems > Open Source.
