Re: [Emc-users] #ifdef

Thanks Phil, I just broke it and lost pulses to the spindle. Went back and commented in the other direction and I have my spindle back. Who would have thought this was so hard... John > -Original Message- > From: Phill Carter [mailto:phillcarte...@gmail.com] > Sent: June-16-21 10:45

[Emc-users] Running 440V 3PH 2 speed motor off 220V 3PH or 1PH?

If you have some transformers lying around you could stack the secondaries to get 440V They don't need to be step-up, just sum the secondaries. You need to have them all in phase obviously. Then use a small, single phase 440V VFD Most VFD's under 1Hp accept single or 3ph, but I don't know about

Re: [Emc-users] #ifdef

Not sure I understand. Say for example the existing HAL file has this: net spindle-vel-fb-rps <= hm2_7i92.0.stepgen.05.velocity-fb But now I'm trying to get the HAL file correct so LinuxCNC starts without errors. net spindle-vel-fb-rps <= hm2_7i92.0.encoder.01.velocity

Re: [Emc-users] #ifdef

What you are asking for is a macro pre-processor for HAL files.There is nothing stopping you from doing this. I think most Linux distributions come with "m4" installed. But be warned that you just might get what you asked for. Software that uses a macro preprocessor is notoriously hard to

Is there something like an #ifdef #else #endif in HAL files? Thanks John "ELS! Nothing else works as well for your Lathe" Automation Artisans Inc. www dot autoartisans dot com ___ Emc-users mailing list

Re: [Emc-users] Master builds

I knew when Wheezy went off support I would need to renew the system hardware. The current mobo is an Intel Atom D510, so barely enough to do the job. The new mobo is an ASRock with i5 processor, and a new 6i25 Mesa card. A holiday weekend project, If I can just find that "round-tuit". --J. Ray

[Emc-users] Setting of maximum velocity and acceleration in ini file

Dear Forum, I see, I have to set the maximum velocity and acceleration in ini file at more than one place, like in [DISPLAY], [TRAJ], [AXIS_X], [JOINT_0]. I can also see in [JOINT_0], I need to set two times, one for Max velocity and acceleration and another for STEPGEN MAXVEL and MAXACCEL (25%
