What thickness are you thinking for the back plates? If I were you, I'd build up a test beam, attach a lever (proxy for the Z beam) at the center...
I'm sure I'll p!ss some people off saying this but VCarve is kind of a glorified clip-art engine. OK, so it does a lot more than that but so many...
If the gantry plates are steel they might be ok. AL - would need to be 10-12mm thick at least.
I don't understand how the X and Y rails are constructed. It looks like they are boxes made of sheet material. I must be missing something as...
Yeah, I have a couple that are stuck, too. In a couple of cases I've replaced the low profile ones with screws that take a bigger hex drive -...
Not a nuisance at all. Flaky wiring always has weird symptoms - "I didn't do anything" is the clarion call to check the wiring. I was having...
Actually, you can wire the opto inputs in 2 ways, sig/gnd or +5/sig. It works either way - think of +5 as + and gnd as -.
Well, FWIW, flaky wiring is always fine until it's not. Check your ground wires, too.
There is a thread on another site about cutting embossing dies with a cnc machine. You might want to take a look at it.
Maybe this is a dumb question but how are you using LPT pins to communicate with GRBL?
Yes, that is also a very real possibility though, if only used for GRBL, it's less likely since the pin would have been in input mode. Some of...
Assuming you want the black in that image to stand up and everything else to be cut away, this is where a carving application shines. F-Engrave...
That sounds like a short to ground. The inputs are normally pulled high on the Atmega so somewhere the circuit is pulled low. A visual inspection...
I've never gotten sketchucam to do letters or freeform images very easily. Pocketing has problems with complex irregular shapes. F-Engrave,...
Assuming you are creating designs that stand a few mm above the surrounding material, I think you might be able to use F-Engrave. It can take a...
I have the same machine and while it can "cut" aluminum, it's really not a metal machine. The amount of flex inherent in the design means a very...
I have a CBeam too. Use Sketchup/Sketchucam for some things. F360 for a lot of things. F-Engrave (free) has turned out to be a real gem for...
EMI can be maddening to track down. Moving your spindle wiring away from other wires will help. Switching to NC limit switches can help a lot....
Assuming the machine is cutting precisely and you have the precise diameter of the bit, then what David said is quite important. I have spent way...
The "three way" switch approach works fine with the IOT relay if you feed one side of the switch from the IOT relay (and the other from the...
