Aligning PedalPCB drill template with Tayda drill template

Hi all,

everyone else seems to wrap their head around this stuff more easily than me judging by the forums. I'm trying to work out how to line up the PedalPCB drill template with the Tayda drill template for the Chop Shop v2.

I've used the Tadya drill template from this post and then mapped the co-ordinates in Illustrator (shown as the red circles in the attached picture):

However, when I overlay the PedalPCB drill template from the Chop Shop webpage (the black rings in the picture) they don't line up. I had originally imported the PedalPCB drill template PDF into Illustrator and then dragged it onto the Tayda drill template. But either as a simple copy/paste or when scaled down a little (as in the current picture) they don't line up.

Can someone help me understand what I'm missing? Is one source more accurate than the other here?

Cheers

I would go into the tayda section for predrilled PPCB enclosures they used to sell and check the datasheet. These have the coordinates in them that can help you put them into the drill service tool
 
So here are the basic spacing for pedal pcbs. This would follow the 3 knob template and you just add the led and the switch. Your y coordinate would be the same as the lower knob. The x I would measure from the center of the lower pot hole to the center of the switch hole. If I were to guess it would be -20mm. Robert is usually very consistent so I would say if that’s not accurate it’s within 1/2mm. When in doubt always measure from the board itself.

Thanks for that.

So the vibe I'm getting here is that if you're wanting to use the Tayda drill services and UV printing services (with any hope of the whole thing actually lining up and not having the pedal knobs hanging over text/artwork) then the PedalPCB drill template PDF isn't really accurate. Instead you really have to measure the board yourself with a set of calipers. Does that sound about right?

In which case the co-odinates listed in the Tayda drill press template I linked to above (once checked against the PCB itself) is likely to be the better thing to follow. Am I on the right track here?
 
The pdf is usually pretty accurate but really more for printing out and using it to put on a box. If you want to use the Tayda service use the coordinates from the drill template and move those over. The Tayda service is great!

Yeah the first pedal I made I just painted and drilled myself using the PDF and it came out okay, but obviously there's less ability to fix it up on the fly if Tayda is doing all the drilling and printing so I just wanted to make sure I had it right given the misalignment between the two things as shown in my attached picture. Always something to learn with these pedals!
