Hi All
Well I am new to this forum/site but i have always been intrigued by and also interested in CNC machines.
Well I am embarking on a project at home which will have me building a 737 cockpit. A number of items on the agenda is panels and PCBs. I will be etching my own boards with Ferric Chloride.
Yes, i know, not an electronics site ete etc... However, the reason I have decided to join is that is all else fails i.e. etching of boards or not being able to find someone to engrave/cutout the percpex for me may result in me wanting to build a CNC that needs to be capable of 600mm x 300mm to cut panels and mill PC boards.
This leads me to an important question: How robust would a Dremel be for CNC usage? I have read about too much play on bearings etc etc etc... is it suited to CNC work or plastics and PCBs?? I would rather not have it destroyed but in the same light I don't KNOW i can't afford some fance motor to turn the bits...
It always seems the case - i have been surfing for the last 3-4 hours and always see a mix of stuff and never get down to questions being answered LOL - so, if this has allllllllllll been said before, and i don't doubt it, please humour me. Yes, i am a newbie here but in no way a "newbie" on earth LOL
I have seen some stepper motors i.e. 48 Steps 5V 500mA; 24 Steps 10V 345mA; 24 Steps 5V 625mA; 40 Steps 7.5V 250mA... How does one know what to get? Is more steps better than less? (assumption would say yes) is high mA better? these are simple questions that I don't have answers for...
Thanks agian for any and all responces and my apologies if i have made you swear and question "where does this dude come from" lol  |
