I'm a bit disappointed that I wasn't able to figure this out. I generally think of myself as fairly handy with this stuff, or at the very least, able to follow simple directions... :roll:
I agree, these units tend to put up a fight before going quite.

Re: V2.60 bricked???

Thanks for the update. That is a strange one. We program the bootloader to the boards after the reflow process and hand solder the black connectors. After that we plug each board into a raspberry pi where we upload the GRBL firmware and test that we can send G-Code to it. It's a bit of an concern th...

Re: Sainsmart TB6560 connection

Got a reply from the manufacturer and it went like this: The signal interface of our single axis stepper driver is DIR, STEP, EN,+5V. The +5V is the common terminal. Therefore, it doesn't compatible with your controller. I think there should be a way to still use them but I m not knowledgeable enou...

Thanks! I suspected that. Is there a setting in bCNC that keeps power to the stepper controller (after I take care of the overheating)?
No the DRV8825 drivers need to be manually set at the Resistor Pot(Potentiometer). Be careful not to touch the driver as they get burning hot.

Re: Limit Switch configuration

You should also use NC (normally closed) switches. They are standard in CNC machines and a lot safer than NO. http://www.cnc4everyone.com/safety/limit-switches The GRBL firmware recommends Normally open as in the diagram. We have added noise filtering to the board to take care of most noise issues.

Re: V2.60 bricked???

Hi Andrew,

Have you made any changes to the RPi image? What RPi version do you have? How are you powering your RPi?

Have you tried to directly connect to the HAT? https://wiki.protoneer.co.nz/Raspberry_ ... _interface

Re: Steppers move but not smooth

I've connected NEMA 23 stepper motors to DRV8825 controllers. The move on G commands but not in a continuous movement. They rotate one turn, stop, rotate one turn, stop, etc. until the movement command is complete. Any ideas as to why and how to correct? That sounds like the drivers are overheating...

It appears there is a way around that.
