Centroid Community CNC Support Forum

Hey Shawn, Thanks for the reply. Yep, we've run drag knives for a while using Donek's gear. The Vectric plugin does a pretty good job. Funny enough, I just built a centroid acorn system for them :D . This one will need to be setup as a 4th channel by hardware pairing on the two long axis motors to o...

Hi Folks,

A buddy contacted me looking for assistance setting up an Eot-3 oscillating tangential knife. I'm wondering if anyone out there is running the same or similar t-knife on their system. If so, what software and post are you using?

Thanks
Matt

Thanks for putting this together. Of our plethora of shopbots, we have a PRS Alpha and I was curious about how that conversion process might work. I also like the idea of sharing the x axis to open up a spot for rotary, something we had been thinking about lately.

I freely admit to badgering, cajoling, bribing, and if you ask Matt, humiliating these guys into getting on board with Centroid and becoming part of what may be the best and most helpful forum on the net. I'm Matt....can confirm the humiliation :lol: :lol: . However, all of our chats are always a l...

Matt... I didnt realize you were converting that "ol gal over in the corner". She has been a workhorse for sure. One down, four to go! Just wait till you upgrade one of the newer ones. Thanks for posting I suppose I should have been more specific since you're aware of our arsenal of shopb...

Did you buy the wireless MPG? If not, you might consider it. Will make setups easier.

Nope, but if I was to convert one of the other modern machines, I'd totally go for it. I've seen it in action and it's totally worth it.

Well, I promised I'd show some video of the machine running. It's nothing glorious, but here's a little action and information. If anyone has any questions, feel free. It seems my post inspired another to take a stab at upgrading their Shopbot V4g control box and I imagine others, even with newer Sh...

Gary, I know your storage is limited... I could MAYBE keep a few of those for you over at our place. I promise you won't end up with an RBK board when you come to get it

Let's see a video of it and the control running! I'll get on that one. Bare in mind, I'm not sure it's going to be the most interesting video as we have strapped it down pretty hard in terms of it's accel/decel/move/jog rates to keep it running slow but steady. It is after all a 17 year old machine...

Thinking about either buying one of Gary's upgrades, or building one myself. I have an old PRT with a 4G upgrade. Looking at the Acorn wiring diagram for the Gecko 203V's I see the need for a "220 OHM Pull Up resistor". Is that only necessary when you don't go the route of the DB25 connec...
