Re: Cheap closed-loop drivers. Am I asking for trouble?

No, I want to experiment with it and learn things that aren't already written down somewhere. It's real hard to get a straight answer around here...

Re: Cheap closed-loop drivers. Am I asking for trouble?

They're designed mainly for 3D printers. Not sure what kind of torque specs you would get out of them, they are likely set to run in "Stealth Chop" mode to make them quiet. Is it a mini lathe? Hey, they must be good for you, they're "Lower Calorific"! :lol: Yeah, it's an 8 inch ...

Re: Cheap closed-loop drivers. Am I asking for trouble?

Hm. That was not an answer to any question that I asked, but thanks for googling something for me. I have these already, as I stated in the first post. Free is as cheap as it gets. If you mean they're expensive because they're going to break, you could have at least offered a crumb of evidence to su...

Cheap closed-loop drivers. Am I asking for trouble?

I have a pair of these https://www.biqu.equipment/products/bigtreetech-s57b-v2-0-closed-loop-driver-control-board-57-stepper-motor-oled-3d-printer-parts stepper driver boards in a drawer, and a lathe build that could use them. I'm not confident enough to just start hooking em up though, so I thought...

Re: G540 mounting ideas. Why is it designed like this?

I'm not questioning the design per se, just trying to understand it. But your explanation was extremely expository, thank you!

My question remains tho, how do other DIY acorn folks handle this? Two separate enclosures?

G540 mounting ideas. Why is it designed like this?

I'm having trouble making sense of the way they designed the case, ports and mounts on the gecko g540. I'm attempting to put all the components for cnc control of a lathe inside the same enclosure, as I assumed everyone would. The problem is that the db25 port is designed to face outside the enclosu...

Re: CNC12 Lathe. G540 config reset button problems

NEVER MIND! I fingered it out myself.

If anyone else ever has this problem, check to make sure you have your e-stop wires run in pairs. I had my NC leads run to opposite boards compared with the common leads. Silly me

CNC12 Lathe. G540 config reset button problems <self resolved>

Hello all, I've been stumped in the process of bench testing my CNC lathe setup. After using the wizard to configure cnc12 for my gecko g540 controller, the "reset" button does not appear to be tripped, though the DRO screen says "emergency stop detected". Pressing the reset butt...

Gecko g540 and 4.2A steppers. Can I add a resistor?

I'm new, and I apologize if I missed another thread that answers this question, but I'd like to ask how important the "current standby mode" is for my use case. I'm converting an 8x16 lathe and I have two 4.2A rated steppers for the two axes and a gecko g540. I don't plan to run the machin...
