The downside with servos is that you’re looking at reduction of some variety, and of course, cost. It also seems somewhat dicey to run a non linear rail machine at those speeds, and while I know many...

Give that a shot and see if it simulates better.
I landed on UCCNC after running Mach3 for years (with ESS), then demoing Mach4, LinuxCNC, and Acorn as I tried to move into a modern platform. My neighbor has a machine with LinuxCNC that I taught...
So I got "free" relays to replace the incorrect ones as I got to keep the incorrect ones (I do have some DC plans so it will work out nicely). I connected it all up tonight and with little surprise...
For the HD I used on my fourth, a 50:1 unit, I sized my Oldham couplers so that it would fail before I damaged the HD. It’s also possible to do that with belt drives. Obviously there is a bit of a...
Case closed, boys. I ordered the 24v-380v AC solenoids, I received the 5v-200v DC solenoid. I didn’t read the label, and so I spent two our three hours messing around with the wrong parts. Seems like...
Well, no luck with those tests. Same results. It also seems my fan blew after leaving it run on 70v for a half hour, it won't run on any outlet.
It seems these SSRs are leaking like 70v when off....
I soldered up a 15k resistor with a bunch of 2.8k and 3.5k resistors (not sure wattage). I connected it across 1 & 2 on the SSR. Same result.
I measure dthe voltage from the "off" side of the SSR...
Okay, 2w it is.
14k if my math is right?
I’m in the US, so 110/120 AC.
Edit: fat fingers, lazy proofing
Thanks!
The main thing is that I have four distinct and switchable relays now, which is a huge improvement. I'm close to being functional again should I get the leakage worked out.
Any guess on...
Came across this video, same guy that was posted earlier with the tear down on the Fotek unit.

So yeah, I'll have to test with my...
My wife hasn't showered since like Sunday, she's been too sick to get out of bed for the most part. I don't think she noticed my lack of hygiene. She's improving though, she could come home as early...
I got the Fotek units connected up. I ended up installing four of them, all running on 5v, all connected to the four outputs on the MX3660.
I can switch them all on and off, but they all have a...
I bet they replaced Kirk with Picard.
I ship to CA all the time for my business. It's a real bummer when I'm sending $100 USD of parts and it costs $43 to get it there.
Many of my customers have U.S. shipping addresses that they cross...
I think the hand writing is on the wall here. I need to buy the Fotek units. Continuing to mess with this relay board simply doesn't make any sense.
I certainly appreciate everybody's contribution...
The C10 is connected to the UC300eth-5lpt.
The behavior of the MX3660 outputs are consistent with the C10 removed or plugged in.
I have not even attempted to configure the C10 jumpers, I've...
I get 0V (off) and 5V (on) across the 1k5 resistor. This solves the dimly lit LED issue when off.
The multiple output issue is persistent.
The SSR switches on/off, though sometimes gets caught in the unknown state, meaning the LED light in this video sort of flickers unpleasantly. I tried to catch it in the unknown state, of course it...
Here’s a video.
Note how the LED’s lit dimly despite being in an off state on the controller, then when the pin is activated they turn on fully. Also, sorry for the shaky video, I was recording...
I totally misinterpreted the drawing. I really need to take a class on fundamentals of this stuff.
I recently installed a C10 BOB as I needed additional inputs for encoder and some proximity...
Thanks, I'll give it a shot with something like .7k, maybe .5k.
Britt's suggestion is a good one, definitely consider it. I think there's an offshoot the Grbl that has backlash comp, but I can't remember the name.
Fusion360 is the go to software these days. It...
Also, John-100, I came across a previous post where you commented heavily regarding the MX3660 and I basically followed your guides there. This was from a few years ago. That's where I got the idea...
Just for fun I moved my wire (the one that connects to the relay input) from Output 2- over to Output 3-. Same result, the LED on the relay board lights faintly before activating the port/pin. When...
That achieved the same results as connecting V+ to Output 1-, and linking Output 1+ to Input 1.
Output 1 and 2 turn on simultaneously, despite me having Output 2 turned off in ports and pins....
I also said "I've tried connecting 5v+ to Output 1+, then running a lead from Output 1- to the relay input 1. I can't recall now, but either it didn't function or the results were the same."
I'm...
That's how I connected it the first time I set it up. It makes perfect sense to me, but I couldn't get it to work. I'll try again though.
