Just wanted to see the mill run some G-Code. I'll be working on the limit switches and homing switches now. I want to get them installed before I make chips.
All of your videos are by far the best I’ve seen for G0704 conversion. Excellent content and video quality. Looking fwd to your next ‘lesson’! Ps: I’ve been building my conversion for almost 4 years with DMM servos and the acorn board. I fried the Z drive when I sent 48v to the 5v cable by not remembering I inverted the location of the plugs on the cabinet. Project is on hold for now, but I’m really interested in getting away from Windows computers and learning Linux system one day. Your control cabinet is a work of art...thanks for sharing your expertise!
Thank you very much. I had a pretty good idea what I was getting into with the CNC conversion... but didn't have a clue about the time it would take to produce the videos. Though I don't regret it. Learning DaVinci Resolve on top of LinuxCNC and basic machining keeps me busy. 🤔
Thanks, Regarding the closed loop steppers... The CNC program (LinuxCNC in this case) generates the DRO output, which is calculated, and indicates where the cutter "should be". If everything is working properly the closed loop stepper has no advantage over an open-loop stepper. It's when something goes wrong that the closed-loop stepper is useful. Too fast of a feed rate, for example, may cause missed steppes, and the closed loop stepper system can be configured to alarm out and stop the mill. I have mine configured so that the mill will stop if the error is greater than 0.002". Servos are better, but closed loop steppers are cheaper. Closed loop steppers... Better than open-loop, not as good as servos. IMO.
I had to move across the country and the mill/controller is not assembled at the moment. I have a great deal of preparation (site clean up) to do before I can get it working again. Follow-up videos are on my to-do list, but it may be a while...

Very nice. With the closed loop stepper motors, no dro scales required? Readouts are provided by the stepper encoder and step caloibrations?
Thanks,

@@joat_mon thanks for the explanation.
Damnnn what happened? Was hoping too see it millong some parts.
