In a response to an earlier post of mine where I had stated that the CNC machine was 'almost done', a friend of mine said "Great! 90% down, only 90% to go!"
This comment is becoming more prophetic than I'd like.
The machine has been capable of movement for a few days now, but the x axis has been troublesome. Even though it's being driven by a beefy NEMA34 motor that should be capable of over 600 oz-in of torque, I've been able to stop it with just a couple fingers. After sleeping on the problem Monday night, I decided to check the documentation of the motors and the driver boards, and discovered that the boards can only supply 4.3A of current, while the motor wants 5.5A. After consulting with some of my friends at the Asylum and some testing, we've decided that the best course of action is to order another smaller NEMA23 motor like the ones currently driving the Y and Z axises, which we know the driver boards can handle.
Some good news is that I had an interview with Because We Can for their internship position that went very well. However, I wouldn't be available until June, and they said that because of their size they can't reliably plan that far ahead. Still, I'm pretty optimistic about the opportunity, and will be staying in touch with them.
