[Emc-users] Kicad to HAL
I came across this recently when working on Hal components. https://softsolder.com/2021/04/08/kicad-to-hal-overview/ Kicad-to-HAL program converts a specially drawn Kicad schematic describing the hardware and interconnections into the HAL configuration file required to set up the machine. ___ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
Re: [Emc-users] Schematics
Hi Thaddeus, I second Chris on using Kicad. I just started with it a few weeks ago and it's very good. Easy to use, lots of libraries and it's really easy to edit or make new components in case you don't find what you want.

If relays are correctly designed door will be locked until relays are fully closed. Nicklas Karlsson Long answer, might have missed some details below. So in the event of a Fault, the whole machine is powered down. This powerdown is also the fault reset. Because they pulse the Fault while powering up as you press F2 again, there is a oneshot triggered by F2 on that disables the fault detection for about .8 seconds, otherwise it faults on the power up. Forever. The Sheldon lathe is all by SSR's as the 127 volt motor power is by one leg of the 254. Control trigger straight from the 7i90. The GO704 has an even more complex time delay startup to limit the inrush as it spindle motor supply has too many microfarads that must be be charged slowly else it clears a 30 amp breaker in the service if switched straight on, so it gets a 50 ohm 200 watt resistor in series with its line feed for about 4 seconds. So now it runs on a 20amp breaker that is right at its trip point if the spindle motor stalls as the pico pwmservo that drives it is set for an 18 amp max. There, if I had those motors on it, but they are regular 2 phase steppers, I revert to resistor limits for 1 second to give the motors time to get stopped, faster than just dropping power. So there two SSR's involved there. TLM is in the process of being converted to a full poweroff, but has normal steppers. Basicly the machines are dead until F2 has been toggled on, then pull the tool if its a lathe and rehome. The lathes get homed at the X out stop first, then Z. On the 6040, Z first, at the top to save broken tooling, then Y at the front, X to the left, then B to whatever offset is zero degrees. All that is subject to fine tuning yet as I need to recal Z for the new motor too. The 6040 has had the spindle raised in its mount to gain some vertical range at the same time, but I've not yet re-attached a shares linear scale to re-calibrate it. Assuming the same u-step divisor in the driver, I just multiplied its scale in the .ini file by 1.5, seems pretty close, these motors are 1.2 degree motors, not 1.8 degree. Changing the Z motor took the up speed max from about 20mm/sec to about 150 going up, the OEM motor could just barely lift a decent spindle motor. This 1nm motor lifts it with authority. This is the third time I've rebuilt the electronics on this 6040, the OEM supplied stuff was junk, incapable of moving the machine, so it went ino the trash trailer about a week after I boght it. And it has a lot of gingerbread I'm still tracing out, bringing to life in the .hal file, mounting and wiring up. When done, the mist checkbox will only control the liquid pump while the gui controls the volume, and the flood checkbox will enable the air compressors to drive the mister with more gui controlling the pressure, so I can clear sawdust with a dry air blow. I intend to make some vise screws for my and others woodworking bench vises, buttress threads on about a 1.9" diameter stick of hard maple, 2 start threads with a 12mm pitch. 3d printed in PETG half nuts, many times stronger than PLA, are alike with 2 starts, and 2 starts for faster clamping on a board. Current G-code is for a 12mm per turn pitch, fine tuned to exactly match the nuts
