Progress update on the Acorn build. Wow, just wow. The motion is so smooth and stepper noise is basically non existent. What a difference this upgrade has made. The use of the pendant style jog wheel is a dream compared to the joystick when edge finding parts and the ability to have movement in the…

Awesome, glad it’s been working well. After a vac table, new steppers are my next project, which might force me to update the drivers and controller… we’ll see.

@trlwoodworks To be honest, if you are planning an upgrade, the controller should be your starting point. Starting with the steppers is like putting the cart before the horse or like buying an expensive camera body but using a basic lens to bring in the light. Higher quality signal generation/motion…

@alldaysammyj , I just noticed this on the first pic. Are you running the 2 larger power supplies in parallel? Assume the small one is for the Acorn board. [image]

Doubtful, as the Onefinity controller will not support a 4th axis.

I would continue to research what else is involved with opting out of the 1F controller, as it involves more than just attaching the acorn (or other controller - I am using a Masso G3). You will need to purchase other hardware, and set up wiring for homing sensors, etc… This will add cost, time, and…

Hey Bill, hey Larry, hey Tom, [image] Machinist: Doubtful, as the Onefinity controller will not support a 4th axis. I doubt Onefinity will make one available, but the accessory market is full of them . Regarding the ability of the Onefinity or the Buildbotics Controller to use the fourth ste…
