Re: Limit Switches and Homing Issue

Chris, Thanks for sending your configuration. I have it loaded on my machine. I had to make a few changes in the limit switch configuration to make it match my machine. I only have limit switches on one end of each axis. I ended up with my x-axis limit switch being wired as a maximum limit but your ...

Re: Limit Switches and Homing Issue

Hmmm, Please reply with your system configuration as an attachment. You can get your configuration using the following procedure: 1. Go to the "General" page on the Buildbotics Controller. 2. Click "Backup" 3. Save the resulting json file to your local computer. 4. Attach that configuration file to ...

Re: Limit Switches and Homing Issue

Chris, The problem may be that the limit switch is engaged before you even start the sequence. Try disabling the min 0 switch in the Motor 0 configuration page. Then clear the estop by clicking the estop button. Then move the spindle away from the switch. Then, re-enable the switch and try your homi...

Re: Limit Switches and Homing Issue

Chris, From your first post, it looks like the Motor 0 min switch is active. It is possible that the switch is still engaged. If you can see it, please verify that it has opened. Another way to test is to verify that you do not have ground on pin 3. If the switch is still active, try increasing the ...

Re: Limit Switches and Homing Issue

Chris,

You have to set up the soft limits on your motors to make the limit switches work correctly. Try setting those up on the Motor configuration pages and let me know how it goes.

Re: Kern laser retrofit

It only takes a minute or two. Your computer needs to be connected to the internet. Once you click Upgrade, you get a dialog that asks for a password. The default password is 'buildbotics'.

Remote Video from the Buildbotics CNC Controller.

It's easy, just connect a web camera to the USB port and reboot the controller. The web camera must be compatible with the Raspberry PI. Here is a link describing compatibility of web cameras with the Raspberry PI. https://elinux.org/RPi_USB_Webcams Here is a video demonstration of the Buildbotics C...

Re: Acctek AKM1212 CNC Router

The Buildbotics Controller cannot supply signals to the Leadshine drivers. Did your motors appear to stall before the power supply shut down? It is possible that your Mean Well power supply did not cut out due to overcurrent. When motors stall, the inertia of the motor is dissipated by feeding curre...

Re: Acctek AKM1212 CNC Router

I'm glad your motors are all moving. How did you end up connecting the axis that is driven with two motors? The spindle could pose a problem. Communicating via RS485 is only part of the issue. The exact commands are specific to each spindle. Unless, it uses the same protocol as the Huanyang spindles...

Re: Acctek AKM1212 CNC Router

Sounds like a fun project. There are three ways that you can hook up two motors for a single axis. 1. Wire the motors in parallel from a single port. This method only works if the motor rating for the individual motors is 3 amps or less because the total current available from a single driver port i...
