Re: Unable to upload gcode

I can help you go back to 0.4.12 to see if that helps. Do you want to do that?

Re: AMB PWM Spindle

You should try a module like this: https://www.ebay.com/itm/3-3V-PWM-100HZ-3KHZ-Signal-to-0-10V-Voltage-Converter-D-A-Digital-Analog-Module/163596299408?hash=item2617196c90:g:rR4AAOSwJ8hcig-o You will most likely find that it allows nearly the full speed range, but is not particularly accurate. If y...

Re: AMB PWM Spindle

The referenced link says that the speed control is achieved through a 0-10Volt analog input. Are you connecting this directly to the 0-3.3 Volt PWM output on the Buildbotics Controller, or do you have an adapter that converts the 3.3VPWM to a 0-10V analog output?

Re: AMB PWM Spindle

Can you post pictures of your spindle and spindle controller, and a screenshot of your spindle configuration on the BB Controller? This would help me get started making some coherent suggestions.

Re: Trying to find good stepper motors

Missed steps can be caused by lots of things. Can you describe your system? What kind of controller do you have? What is the model number of your motors? How fast are you driving them? Are you sure that your mechanics are not binding?

Re: Unable to upload gcode

Hmmm, Here's a few questions: - Are you able to see the files on your thumb drive before you attempt to load the file? - Are you able to load files that are already in the pull-down menu? - How many files do you have in the pull-down menu? - How big is the file that you are trying to load? - Does it...

The joy stick will not travel past the soft limits if the machine has been homed.

Re: Proximity Sensor pnp or npn

The limit switch outputs connect directly the AVR microprocessor outputs. You can use any type of proximity sensor that you want as long as it never connects the output from the BB Controller to more than 3.3 Volts or less than 0 Volts.

Re: Thoughts after a few months tinkering with BB and observing other controllers

I'm not sure I know what you are asking, but it sounds like you are asking how to configure the motors. That is done on the motor configuration pages. You can find an explanation of the motor configuration pages in the manual. Here is a link to the section: https://buildbotics.com/manual/#motor-page...
