4-Gang 1-Way Switch To Control 3 Power Supplies and a Router Independently

Category: Computers and Hardware

I thought I'd add some pictures - PSU - Dinkle terminals - relay - lazy wiring board - contactor - Monetary NO push button to energise relay (SW1in schematic), rotary type switch to control power to circuit (SW2 in schematic). In my control panel the contactor is not mounted close to the relay but closer to the power supply supply minimizes the length of the AC power cables. This was just quickly thrown togther for demo purposes, in the cabinet it's more professional looking.

And a close up of the lazy wiring board, diodes are snubber diodes. Wiring is so much easier. Relay & contactor can be same or different voltages, hence the R+ & R- and C+ & C- points on the board. The 240AC is wired directly to the terminals on the contactor.

Encoder on 7i95t

Category: General LinuxCNC Questions

Sorry... that was a test i did.
Its set to 1000 usually. (Same problem ocours)
(1000 [PPR] x 4) / (4 [mm/rev]) = 1000 [Pulses/mm]
(Is this correct, when seeing in the halshow, that the encoder counts 4000 counts per rotation?)

But it seems, to not even use the encoder_scale, because i can just comment it out, without it throwing me an error at the start-up...

ENCODER_SCALE = 1
????
This should be 4 times the encoder PPR divided by the total distance moved for one rotation.

Encoder on 7i95t

Category: General LinuxCNC Questions

I've been following this excellent step-by-step guide, but I'm currently stuck with a problem: the DRO is off by a factor of 1000. When I move the machine by one leadscrew rotation—which should be 4 mm (since it's a 4 mm/rev leadscrew)—the DRO now shows 4000 mm instead.Previously, it correctly showed 4 mm, so something must have changed, but I can't figure out what. Could someone please take a look at my configuration files?

I just discovery tuna, realtime IRQ tuning, my first impression was great.
Just test it at buster, going to bookworm now.

Sure, when I did this, I uploaded the unmodified nvem-full-config.txt - from the Remora repo.

Reading the upload script, it looks like it makes a copy of what I feed into it and writes it to this config.txt file? Comparing the two documents showed them as identical.

Something else worth mentioning, I had read that the 4/5/6 axis boards used the same hardware, and that Remora doesn't care which version of the board you get. I bought a 4 axis version as the others were more expensive for seemingly no value add if used with Remora. I did use my multimeter and could trace the 5 and 6 axis step/dir pins back to what looks like a buffer IC at least. Hopefully I don't have some later version of the board that has additional locks in place.

In fact, with torque control, I don't think Linuxcnc is up to the task, you should choose OMRON..... PMAC controller.

Usually, the controller with a position closed-loop, the generation of following errors, and the PID controller of the upper computer, has little to do with it, because the position loop can be adjusted in the drive. At the same time, the following error = the maximum feed speed is proportional to the position loop gain

Oh so those are now all in one file?
There were 3 back then, quick start, documentation and integrator's manual.
I recall thinking "how is this software under 5MB in size while documentation is nearly 30MB???"

Just a heads up. Tommy's link is to Linuxcnc v 2.6 and our release version is now 2.9 so it will be obsolete in places.
The PDF files are available from the Documention page but are just a copy of the content in the HTML version which I tend to use in preference,
But none the less I too was gobsmacked when starting off to find the documentation runs to 1347 pages!
2.9 version: linuxcnc.org/docs/stable/pdf/LinuxCNC_Documentation.pdf
