JLCPCB opinions and more
blazini36:
I use them several times for prototyping boards in quantities of 10. Once I shrunk my boards down to 100mm x 75mm I realized it got super cheap. Shipping is like $18 but It still beats out anything else when the whole thing is $27 and I get them in 3 days. I wanted to try Oshpark because I like to support American companies whenever possible, but I couldn't figure out why the hell the same gerber file cost like $300 and shipping was something like 12 days. I'm not a pro and I tend to make mistakes on boards but I don't have time to breadboard everything so a quick inexpensive PCB that I can slap some solder paste on and cook is what I need. Now that I know my last prototype is a winner I think I'm going to see if I can get a reasonable price out of Oshpark since I can afford to wait, it's still a low volume board. I don't bother with V-cuts or paneling or anything.
I will say that JLCPCB has always sent very high quality boards very fast. Every mistake on a board I've had was my own, so I have zero complaints about them. I also use AllPCB for single sided aluminum boards because JLC doesn't seem to do them. I haven't had any problems with them at all either except they don't seem to be as convenient, and their site doesn't have a built in gerber viewer. They are also very fast.
Edit: nevermind Oshpark, 3 PCBs for $54 when I just paid $27 for 10. And that was an extra $8 for blue PCBs.
TERRA Operative:
I've used them a few times for their edge card service where they chamfer the edges for you. (Which Seeed don't offer AFAIK)
One lot came missing the chamfer, but they refunded and the next lot that came were perfect.
Gold plating seems fine and the silkscreen and copper layer quality have no issues so far either.

I have contacted their support by e-mail for help with my gerbers and truly enough I am amazed.
Granted I did it within their working hours but they replied to be within the hour.
They told me that my gerber designs seem ok.

You were right about that I added V-score (for eagle it´s layer 102) and exported only the V-score in a GKO line along with comments on the same layer.7
Seems that they did not have any trouble handling that.
About the renegade ball:
Yes SeeedStudio CAM job works. I have only added the V-scoring layer and some more silkscreen options, but apart from that they were quite happy with it.
And yes, from what it seems so far, cause I have not concluded with my order, if you do the panel yourself, you only get to pay 2$ for 10 boards/panels.
I have watched one of Dave´s older videos and decided to make my boards according to his suggestions, that also fit my purpose.
For reasons of completion I include a photo of the panel. It´s for my OSH project posted here: https://www.eevblog.com/forum/oshw/openservocan-(-for-hobby-standard-size-servos)/

Does that mean V-score along the outlines of the 100x100 mm area?
Or does that mean V-score INSIDE the 100x100 mm area?
Does that mean ONE V-score or several?

I am still in contact with their support, I´ve sent a second e-mail to clarify some other things and I have not yet concluded the order.
Although in their email they said and I quote: "We can make V-cuts, plated slots and milling.But we cannot make rectangle plated slots."
I really think this whole situation begs for a proper tutorial. Let me finish first my dealing with them and I will write everything in detail thereafter.
Edit: I do doubt that they do V-score selectively inside the PCB. V-scoring is done by cutting wheels not a CNC.
