Mary's MakeShop DIY CNC Video Channel

Great job there lass!

You young folks' communications & production skills on youtube flabbergast me. I did a few video editing projects back in the 80's on VHS/S-VHS and it was a real pain.

Anyway, welcome aboard & keep 'em coming!

Thanks DICKEYBIRD! I use Movavi studio, so it’s been pretty intuitive. I know I have it super easy compared to your video editing projects back in the day. I already know where to start improving though... I didn’t realize until I uploaded the video that my cockatiel, Sunshine, was chirping the entire time. Oops!

Hopefully my videos just get better from here!

Sunshine can chirp all she wants. I keeps it real. You were a natural on the video!

Mary's MakeShop: My Centroid Acorn CNC Control System Set-up

Mary, nice job. However, I think you may have something incorrect in your video. You showed a CNC controller the had a connector that was not a DB25, and indicated that it was not meant to interface with a parallel port. That is incorrect. The port is a centronics interface and was found on printers and the like some time ago. These connectors are compatible, but require the correct cable to interface. Just thought you may like to know.

I saw that too....Mike, we are showing our age here (That's why I didn't mention it) Oh remember Okidata? Star Micronics (oh, never mind)
However, because it has the Centronics connector it would be interesting to see the schematic from it. Never know what the Chinese do.

One of the new features in Acorn 3 is the ability to assign the pins on the DB25. It offers that flexibility so you can do as Mary did, plug in a DB25 from a legacy parallel port system and assign the signals to match the breakout board inputs or motor driver inputs provided it uses the DB25

Hello Mike and Marty! Thank you so much for the catch. I messed up and should have clarified. In the router I found on Ebay that I used as an example of what not to buy, I should have just circled the USB port when talking about it not being compatible with the Acorn(picture below).

Based on the labeling and other diagrams, it looks like the Centronics interface is the control output for the engraving machine’s motors and not the Acorn. Or is there a cable that could interface from the USB to DB25(parallel port) connector? I'll look into that and sorry if it's already discussed on this forum.

Anyway, thanks for your feedback. I really appreciate it!

Not bad at all!

I really liked it. Looking forward to seeing your machine make some cuts.

Thanks Reedfirst! I'm stoked to start cutting the walnut I have and try out my video time-lapse skills.

Mary,

Congrats on a great video. The Acorn club is growing

Russ

Thanks Russ!! Happy to be part of the Acorn club

Well Mary, I think you might be right! The USB appears to be the motion control input and they chose to use the Centronics connector for all the output connector, not a great choice but hey, we know better.

Mike, we are showing our age here

Yes, yes we are. I won't mention the Dec printer terminals I learned to program on. Oops...

Keep up the good work Mary. Impressive, using Fusion CAD/CAM and tinkering around with the G-code....
